Beat the Springs in Donkey Kong

Another arcade classic strategy rundown, and again c0ncerning Donkey Kong. As the video rightly notes, the Springs board, a.k.a. Elevators, is most devoted players’ greatest barrier to playing to the kill screen, and even pros mess it up sometimes. I think it’s the worst part of the game, personally. Donkey Kong is great, says I, because it’s open to multiple strategies, while the later Elevators boards have to be finished a specific way, all because of those springs. That way is what this video (4m) is about.

Sadly the video has been made non-embedable, so it’s up to you to follow the link, if you care. The video encapsulates information on donkeykongforum.net (which it mislinks). That link is some hardcore geekery, of the kind beloved to Set Side B’s cadre of pixelated aliens, so please take a look.

Here’s the basics, in text form. Donkey Kong gets more difficult over the course of five “levels.” These are different from “boards,” a.k.a. “racks” or “screens.” In the corner of the screen there’s a notice, “L=X” where X is some number. That’s the Level. It goes up by one every time you finish a Rivets board.

The problem is, starting with Level 2, the spots at which the springs hit the ground is slightly randomized. The final climb up to Pauline’s platform is super dangerous, since Mario is vulnerable the whole way. Level 4 is the hardest difficulty for the springs on Elevators, and you have to handle it a very specific way: climb up to the first safe spot, wait for a spring that comes out bouncing at a specific location (near DK’s right foot) then running to another safe spot, then waiting for another specific spring speed to rush over and up the ladder.

So go forth and conquer the elevators, and as Coily the Sprite reminds us:

Great Mappy Strategy Video

Our retro arcade strategy week is over, but this is a related video that I’ve been sitting on for quite a while. The Disconnector made a very nice strategy video (20 minutes) for Namco’s cult favorite cat-and-mouse game Mappy. It works as both an introduction and a guide to the game as it develops.

Not only is the information good, but it’s really well put together! Looking through the rest of their channel, while the post about other games (most recently about Robotron [8 minutes]) it seems to be the only strategy video of its sort. I hope they make more, I think they have a talent for it!

The @!#?@! of Q*Bert

Fourth of five retro arcade strategy posts this week, how about we learn how to play the swearingist classic game: Q*bert.

Here’s a video that covers what each of Q*bert’s five levels is like (18 minutes):

You play Q*bert, and at first it seems simple. Level 1, you jump on each cube once. Slick and/0r Sam may change them back once in a while, but you can just jump on them again.

Level 2, you jump on each cube twice. That makes each level twice as long, but still not much of a problem. The rising difficulty here comes from more and faster enemies.

Then you reach Level 3, and Q*bert becomes a much different game. Now jumping on a solved cube unsolves it. If you don’t work out how to handle this, levels can drag on indefinitely. It’s a bit of a wall for players here, and Slick and Sam become much more annoying.

Level 4 is similar, except you have to jump on each cube twice, and jumping on one after it’s complete changes it back to the intermediate color. But worst is Level 5, where jumping on a solved cube changes it back to the original color. This is a huge change, for it means the pyramid can actually become unsolvable without using a Disk, or waiting for Slick or Sam to come in and reset some of the cubes. For more details, I refer you to the video. You know, the one I embedded a few paragraphs up. Go! And if you think that’s nuts, check out what happens in the unreleased sequel Faster, Harder, More Challenging Q*bert (GameFAQs link).

Here’s another strategy video (10 minutes), with tips by Jody Martin, released to the Youtube channel of Starfighters Arcade. It more basic in focus, but is more interested in explaining enemy behavior and how to react to it.

Something I’ve thought is interesting about Q*bert, which is also true of Pac-Man, is that it’s like a turn-based game, but where you can play around with the timing of the moves. I’ll try to explain.

While both games let you decide when to make decisions, both encourage playing in a discrete, point-by-point way. When Q*bert lands on a cube, there’s a limited number of decisions they can make, other than waiting to make your move. In Pac-Man, your moves are constrained to the maze paths, but you can turn slightly early, you can pause when you hit a wall, and you can double back at any point. You usually don’t want to pause or double back in that game, because they introduce uncertainty in patterns (although a few patterns rely on them, which makes them much harder to perform). Q*bert is resistant to patterns, using pseudorandomness to affect the paths of the balls and most enemies, and the player’s ability to break out of the rigid temporal confines of that game’s movement is more helpful.

Contrast both games to Robotron and Defender. Those games have “free” movement, they’re not confined to a playfield with limited choices but let the player move around how they want. In actuality they’re games where the turns are taken in real time each frame. That adds a much greater role for player skill, but it also requires you to be much more precise.

Defender Strategy

Defender’s difficulty is legendary. Craig Kubey in The Winner’s Guide to Video Games said it was like being locked in a closet with a swarm of killer bees, and I actually think that’s not overstatement. And yet, people have flipped Defender’s score counter many times in a single game.

In an 18-minute strategy session, Joe Dearman explains the basics of playing Defender well, but I’m afraid if you don’t have a certain base facility it might be hopeless. Although I’m generally good at video games, I don’t seem to have it myself. Take a look and see if this looks like something you might be good at, but be warned, Defender’s controls themselves are complicated, with a lever and five buttons, although I dunno, game controllers these days tend to have many more than that. It is important, however, not to underestimate this game. It will rapidly annihilate you if you aren’t very good.

Both Defender and Robotron 2084, mentioned yesterday, were made by Williams, and designed by Eugene Jarvis, who still works in arcade game production today, or did last time I checked.

Another thing these games have in common is they’re very adjustable. Operators can choose starting difficulty, ending difficulty and on which wave it’s reached. This thread at arcade-museum.com breaks down the different romsets and differences between them. The earlier roms, “Blue” and “Green,” are generally harder, and increase in difficulty through 99 possible levels. The most common and latest set, “Red,” only has 30 effective levels.

At the higher numbers of Blue and Green, weird behavior can be seen. Defender has an enemy called the Baiter, which exists to harass the player if they take too long in clearing a wave of other enemies. At maximum difficulty Baiters become hilariously numerous, the game sending them in about once every two or three seconds. Watch a few minutes of this game with the wave difficulty settings cranked up to maximum from wave 1 (39 minutes). The extra ship level is set it easier than normal, needing just 5K to get an extra, and it’s set to restore all the Humanoids every wave, but that’s mostly to make the game possible, although there does exist video of someone surviving maximum difficulty with ships and Humanoids at normal settings, up to a score of 909K. (1 hour 7 minutes, somehow).

Here is the first of those two links, I’ll leave the other for you to click on if you’re interested. Both of them have the amazingly persistent Baiters, and in both of them the player manages to hold up under the pressure, for a while anyway.

Robotron 2084 Strategy from arcadeimpossible

It’s the third of this week’s classic arcade strategy find posts, and today’s dedicated to the original twin-stick shooter, Robotron 2084.

Robotron’s what I’d call a very pure game. It’s simple in play, nowhere near as complex as Eugene Jarvis’ first game Defender, but deep despite it. The left joystick moves, the right joystick fires, and until you get used to that you’ll have short games. In fact, you’ll probably have short games regardless. It is ruthless.

These videos feature host “Greg” and star player “Darrin,” who is the one giving most of the advice. The first video covers the first nine waves (5½ minutes). They set the template for the game: there are theme levels that cycle every ten waves. There are Spheroid, Quark, Brain and, for levels ending in 9, Grunt waves that completely surround you with enemies right from the start, and each poses its own kind of challenge.

The second video covers intermediate-level play, and wave beginnings (7 minutes):

The videos mention three parts, but it appears that only two were ever uploaded. They mention a site in their descriptions, robotron2084guidebook.com. In the 12 years since the videos were posted that site’s gone dark, but being a text site it’s pretty well preserved on the Wayback Machine, and has lots of good information. They also mention video on the high score site scoreground.com, but sadly it’s also defunct, and the mentioned video that was hosted there is probably lost. If there’s one good thing about Google, I guess, it’s that they let Youtube videos persist on their site for decades without culling them too much.

Donkey Kong High-Level Basics

Continuing with this week’s theme of classic arcade strategy videos, these Donkey Kong videos are from a variety of Youtube sources.

Rob O’Hara on basic strategy (9½ minutes). Note that he’s playing on one of those multi-machine emulators so the sounds are a little off.

arcadeimpossible talks with former world record holder Hank Chen (22 minutes):

Getting deeper into the weeds now. Here’s a high-level strategy video on just the Barrel (a.k.a. Girders) boards (41 minutes!). All the following videos are from Chambers_N Gaming:

Was that a lot to say on this one subject? Well hold on, that was just part 1! Here’s part 2, which is another 42 minutes!

And here’s detailed strategy on the Rivets (a.k.a. Ziggurat) boards, although it’s “only” 19 minutes:

That a single game can inspire so much discussion so long after its release speaks volumes about the quality of its design. A lot of it has to do with how much randomness is in the game. Even the best players die sometimes! Donkey Kong is heavily resistant to rote patterns, although there’s still things the player can do to subtly affect each board, and make it more manageable. On the Barrels boards, on higher levels, you can affect when barrels decide to come down ladders by steering towards them as they reach their decision point.

Introducing Simon Tatham’s Puzzles & Tips On Dominosa

I’ve brought up Simon Tatham’s Puzzle Collection here before. It was then, and still is now, one of the great wonders of the World Wide Web, a completely, utterly free, in both beer and libre, collection of randomly-generated puzzles of 40 different styles and counting, available for pretty much every platform. Not currently for Mac, because Simon’s Mac stopped working, but you’re free to compile it yourself if you can.

Let’s delineate the platforms: Windows, Linux, Mac (with the above caveat), Android, iOS, Java and even Javascript. You should be able to field one of those options, right? And which puzzles are provided? Black Box, Bridges, Cube, Dominosa, Fifteen, Filling, Flip, Flood, Galaxies, Guess (Mastermind without the trademarked name), Inertia, Keen, Light Up, Loopy, Magnets, Map, Mines(weeper), Mosaic, Net, Netslide, Palisade, Pattern (a.k.a. Nonograms, or Picross), Pearl, Pegs, Range, Rectangles, Same Game, Signpost, Singles, Sixteen, Slant, Solo (genericized Sokoban), Tents, Towers, Tracks, Twiddle, Undead, Unequal, Unruly and Untangle. Not only will the software generate an endless of stream of puzzles for you to solve, often with a user-selected difficulty, but some platforms will even print out books of these generated puzzles for you to solve, along with an answer key.

The puzzles I’ve boldfaced are what I call Nikoli-style puzzles. Nikoli is a popular Japanese puzzle magazine, the original home of Sudoku, and has a particular kind of logic puzzle that’s really satisfying to play. They usually have simple rules, but with profound implications, and with some thought you can deduce processes to help you solve them. Sudoku aficionados will immediately know what I’m talking about. The main subject of this post is about one of these Nikoli-style puzzles, Dominosa.

Nikoli specializes in human-created puzzles, and Simon Tatham’s Puzzle Collection creates its puzzles by computerized process. These kinds of puzzles really are better when set by hand. But that doesn’t mean the automatically-generated kind doesn’t have its place.

Also, Simon Tatham’s puzzles are completely free, don’t track you, and don’t have ads, making them a real rarity in this money-desperate age. If you need any proof that the app stores of Apple and Google are rigged against you, then consider that the Puzzles have been available on both their platforms for over a decade, but their discovery algorithms never seem to surface them. (Here’s some help in finding them: Google Play, Apple App Store.)

To give you idea of what kind of puzzles these are, and to get you on your way to solving one kind of them, here are my observations about Dominosa. The rest of this post is pretty long, so this is your chance to check out if you don’t want basic tips on how to solve it.


Dominosa, KDE version

Dominosa presents you with a grid of numbers, usually from 0 to 6 (you can choose to solve larger puzzles). The numbers represent the values on a field of dominoes, but the edges between them have been removed, leaving only the numbers of pips that would be on their two sides. Your job is to place dominoes on the field, over the numbers, to reconstruct where they were originally. The puzzle is solved when every number is accounted for, filling the board with exactly one domino of each pair of values, with no contradictions.

I’ll present a series of images representing working out one of these puzzles at a basic level of difficulty. Not all of them are as simple as this.

A Dominosa puzzle, from the Android version of Simon Tatham’s Puzzles.

The way I solve these, I first look through for pairs of numbers. If you’re on a version of the Puzzles with keyboard support, you can press a number to highlight all of its values throughout the board. If you don’t have a keyboard, there will usually be number buttons onscreen that fill the same purpose. There may also be Undo/Redo buttons; if there aren’t, you can use Ctrl-Z/Ctrl-R for that.

I start out by looking for all the zeroes. Here they are:

In a double-six puzzle like this one, there will always be eight of each digit. What I’m hoping to find is exactly one isolated pair of one of the numbers. There’s only one domino with each pair, from 0-0 through to 6-6, so a single pair means that a domino must be there.

No luck with Double-Zero, so I keep going, checking each number in turn. (You can only have up to two digits highlighted at once; pressing a number again turns off its highlighting.)

I have better luck with the 2s: there’s only one adjacent pair. So I click on the space between them to place a domino, as so:

In Nikoli-style puzzles, as you correctly fill out each little bit of the puzzle, it makes the rest of it slightly easier. When you make progress in solving it correctly, the puzzle seems almost to knit together, until the whole grid is complete.

It’s not just single pairs that are useful though. Sometimes you’ll find single triples, either in a straight line as here, or in an L-shape. So long as there aren’t any other adjacent digits of that value in the puzzle, then you know that one of the two possible pairs must be the correct one.

How is that useful? In the below case, there are borders between the digits that the two possible placements have in common. Since one or the other must be correct, the two domino edges that the possibilities share must be edges in the solution. We can mark edges in Dominosa with the right mouse button, or on mobile platforms with a long press:

Above I’ve placed the horizontal edges that the two possible Double-Three locations have in common.

Moving on. There’s a single pair of 4s, so I’ve marked that domino. And there’s an L-shaped arrangement of three 6s. It’s on the outside of the puzzle, so there’s really just one edge to place, like so:

I’ve also started on the second step of the puzzle, looking for non-identical domino pairs. This is where the ability to highlight two different numbers becomes useful.

Now we’re looking for each possible 0-1 combo. There’s three possibilities here, which isn’t helpful.

The process I use is to check for the dominoes with one zero: 0-1, 0-2, 0-3, 0-4, 0-5 and 0-6. After that, the remaining pairs beginning with 1: 1-2, 1-3, 1-4, 1-5 and 1-6. When I move to the next digit, there’s fewer to check, because we’ve already done some: 2-3, 2-4, 2-5, 2-6; then 3-4, 3-5 and 3-6; then 4-5, 4-6, and finally 5-6.

Of the 1-2 domino, there’s only two places where it could be, so I can place edges alongside them. Also, there are two 1-6 pairs. But because we’ve ruled out one of them, when we tried the Double-Sixes, there’s only one pair left that could possibly be the domino.

Ah. Now we have one of the best things we can find: a dead-end. A place with a cul-de-sac, where a domino has to go regardless of its digits. Every digit in the puzzle must connect in one direction, and the 3 to the right of the 4-4 has only one way to go, so that must be where the 3-1 goes. And because of the two edges nearby, the 1-2 also has a location where it has to go.

The great thing about these placements is, they weren’t narrowed down from the lack of other pairs of digits. Since the 3-1 has to go there regardless, all the other 1s by 3s on the board can’t be options, so we can place edges between those numbers.

We’re lucky again; each of these edges produces mandatory domino placements, in the same way!

These, in turn, allow us to place another domino, a 1-4, and to block an edge between another 1 & 4. It results in an unfilled region of the puzzle with only one entrance. Dominoes have exactly two ends, so any region containing an odd number of digits is impossible. This lets us place a useful edge, between a 5 and a 6, because if the edge were below the 6 instead, the region would have 11 digits in it.

Continuing with checking for pairs, there’s a triple, a 1-5-1 with no alternatives around them. Since each puzzle must have exactly one 1-5, it has to be one of these two places, so all the other 1-5s in the puzzle must have edges between them.

And that means a mandatory placement for the 1-0.

Hah, I neglected the mandatory 6-2 at the right side of the puzzle! But I did find a single remaining instance of a 2-4, which I filled in.

And then I noticed the 6-2:

We’ve done about half the puzzle now, but really we don’t have much left to do. The 6-2 we place means we can place edges between the 2 and 6 at the bottom of the puzzle, as so:

We can hurry through the rest of the puzzle. There’s a single triple of 3-4-3, so we can place an edge above its 4:

There’s a single 3-6:

That creates two dead-ends, a Double-3 and 0-4, and then a 4-3:

From here, most of the rest of it can be worked out with the same principles. When we get to small areas like this, often figuring out where to place one domino, or even edge, makes the rest of its region obvious. There’s a small region with a single path into it, so the fact that regions can only have an even number of digits comes into play again.

This puzzle is almost solved, so let’s just jump straight to the solution:

As noted before, most puzzles aren’t this easy. Often after you’ve been through all the possible pairs of digits, you still have a significant amount of puzzle left to do. Usually, if you look carefully at the puzzle, you can figure out placements that, if made, will result in contradictions to the rules of the puzzle. If you find one of those, you can then place an edge between its numbers.

There’s a couple more tricks I know of, but they start getting harder to explain easily here. I’m by no means an expert: I’m sure that experienced Dominosa solvers know tricks I have yet to figure out. I also don’t want to explain too much about how to solve these puzzles, as I got a lot of entertainment in figuring out my solving process, and I’d hate to deny that to you. Most of the processes I’ve mentioned so far are pretty obvious implications of the rules. Revealing the less obvious tricks feels a bit like a spoiler.

One great advantage you have in solving Nikoli-style puzzles on a computer is the Undo feature. Like doing Sudoku by hand, if you reach a point where tricks fail you and solving algorithms leave you stranded, you can progress by making assertions, basically guesses, then working them through until you reach a contradiction. There’s a whole strategy to this: you want to make a single binary, this-or-that guess, and to pick an unlikely guess, one that will prove itself incorrect quickly. Then you can erase the marks you made following your guess, and then mark its opposite.

On a computer, you can undo until the point where you made the guess, with Ctrl-Z. On paper, you’d not only have to remember all the marks you’d made since the guess, but you’d have to erase them all, which makes a huge mess. If you undo too far, you can press Ctrl-R to redo the removed moves. It’s really a tremendous aid!

Give Dominosa a try, and see what you can deduce. If you want to try some of the other Nikoli-style puzzles, that feel similar but have a different process, I recommend Loopy, Slant and Bridges.

Grouping Ghosts in Ms. Pac-Man

Ms. Pac-Man. Currently on the outs with Pac-Man rights-owner Bandai-Namco because its origins weren’t with them, and its developer GCC licensed the rights to another party than them, which has given us such travesties as “Pac-Mom.” Which is a shame, because in general Ms. Pac-Man is a better game than Pac-Man. Its four mazes don’t have the nuance that Pac-Man’s does (there’s no one-way routes, for instance), it doesn’t have scatter periods to give the player a breather during each board, and after board #7 its fruit, and the score award for chasing it down, is random, taking an important measure of skill and just throwing it up in the air and shrugging.

But it does have multiple mazes. And its Red and Pink ghosts behave randomly for the first bit of each board (here’s a prior post about that), eliminating the major design flaw of Pac-Man: its vulnerability to patterns. Pac-Man is certainly not the only game to lack substantive randomness, but the nature of its maze-based play is that it’s relatively easy to perform them. So long as you hold in the direction you need to go at least five frames before you reach an intersection, you can be sure that you’re performing a pattern perfectly, making Pac-Man into an endurance game more than anything. Ms. Pac-Man doesn’t have that problem.

But that doesn’t mean that Ms. Pac-Man can’t be mastered, and the basis of that is through a technique called grouping. Grouping can be done in Pac-Man too, but if you know some good patterns it isn’t necessary. But in Ms. Pac-Man it’s a key skill, both to make sure you eat as many ghosts as possible in the early and mid boards, and for general survival, for a bunch of ghosts in one lump is much easier to avoid than a scattered mess of four separate ghosts.

David Manning’s introductory video on grouping ghosts in Ms. Pac-Man (20m) is ten years old, but it’s still an invaluable aid for players seeking to master that game.

The basic idea is to understand the ways to move in the maze so that pursuing ghosts take slightly different routes to reach you, so that leading ghosts are delayed just a bit, or trailing ghosts approach you slightly faster.

This time I’m going to leave the explanation to the video, but it’s interesting to think about, and to see if you can apply this information yourself.

Someone Other Than Me Talks About Rampart

It’s true! Thanetian Gaming on Youtube has an 18-minute video about Atari Games’ neglected classic Rampart. Remember back in September when I posted a strategy guide that no one asked for over four days? Judging by his video he could stand to read it, but no matter, I’ll accept anyone talking about my favorite arcade game in a positive light!

On Gatekeeper Info, Tim Walz and Crazy Taxi

(EDIT: I’m reminded that AOC is a representative, not a Senator. Which is like, lol, if you care about facts or something. Still I’ve corrected it.)

We don’t post about politics much here. This is entirely not because it might drive people away, but it is because much of the rest of the internet is full of it, and we’re feeling a bit overwhelmed by it all, and the terrible consequences if the wrong person (you know who he is) wins in the US in just a week. Anyway, many of our readers aren’t even in the US, and to all of you, I say, I envy you.

But a weird bit of news came out involving Kamala Harris’* VP** candidate Tim Walz that both edges into our lane and is an excuse to talk about something I’ve long been wanting to remark upon, about Sega’s classic arcade racing-game-but-not Crazy Taxi.

(* For non US-people: Kamala Harris is the Democratic candidate for President in 2024. **”VP” stands for Vice President, a largely ceremonial role, but should something happen to the President, the Vice President becomes the new President.)

I’ve played a lot of Crazy Taxi. I played a lot of Crazy Taxi 2 as well. I had a Dreamcast, for the brief period it existed, and they were unquestionably great games for that system, with amazing (if Youtube-unfriendly) soundtracks. Well as it turns out Tim Walz has great taste in games, because back then he had a Dreamcast too, and he had Crazy Taxi for it. And he streamed a few minutes of it, with terrific Democratic*** House Representative**** Alexandria Ocasio-Cortez.

(***”Democratic” refers to the Democratic Party, the US’s left-ish party that currently serves as our feeble bulwark against the hooting forces of awfulness that beset our entire world. ****”House Representative” means a member of the House of Repesentatives, one of the US’s two Legislative Houses. That concludes the US civics portion of our post.)

Most of the stream was taken up with playing Madden, which isn’t in one of our more favored categories, but the five minutes of Crazy Taxi were posted to Walz’s Youtube channel:

I am conflicted about this video. Walz is one of the most personable people ever to be nominated for high office, a genuinely friendly individual. But he isn’t a great Crazy Taxi player. And it might be because he doesn’t know how to do a maneuver called a “Crazy Dash.”

(Let me say now: I don’t even appreciate making jokes that sound like “he’s bad at gaemz lol im voting for other guy,” the stakes are way too high for me to be able to laugh at that. Just, keep it in your hat/purse/gender neutral container, please.)

But this reminded me of something I’ve thought about for a long time, and was driven (heh) home to me over DragonCon this year. There was a Crazy Taxi machine there, at stand-up model, I think with a slightly flaky gas pedal, that made it unreliable to perform Crazy Dashes.

Crazy Taxi. Image from MobyGames.

A Crazy Dash is simple to perform once you know how. From a halt, with the gear shift in Reverse, in quick succession shift to Drive and slam the gas pedal. If the timing is right, your car will lurch forward with a burst of speed. And if you do this while driving, shifting to Reverse with foot off the gas, then shifting to Drive and flooring it with the same timing as a Dash, it’s called a “Limiter Cut,” and you get an even greater burst of speed!

Crazy Dashes and Limiter Cuts are essential to even slightly good games of Crazy Taxi, which is why the sit down version of the game puts instructions for how to do them on the control panel, why the Dreamcast version’s manual explains precisely how to do them, and why at least one of the squares in the “Crazy Box” challenge mode is all about teaching you how to perform them. It’s what I’ve come to think of as gatekeeper knowledge: it guards the way to good scores and long games. If you don’t know it, you’re doomed to fail.

Image from Kotaku

Crazy Taxi is an arcade game. Even on the Dreamcast, it’s just a direct port of the arcade version with added modes. Arcade games want your money, and they don’t want to give you very long games in exchange for it, so the next player can step up and put in their doomed quarters as well. But the catch is, if good players can’t have decently-playing games, then people won’t play. I heard it said that the average target game length was 90 seconds, and average means a substantial number of games will come in under that mark.

Yet, I can play Crazy Taxi for substantially longer than 90 seconds. I can go for 30 minutes. And it’s thanks in part to the Crazy Dash and the Limiter Cut, essential knowledge for the reckless cabbies of Faux San Francisco.

Because of the DragonCon Crazy Taxi machine’s flaky gas pedal, I didn’t have any 30 minute games there. But I did manage to make the scoreboard, barely, at 20th place, with a score of just over $5,000, getting (by the inflated metrics of its scoring system) a Class S license. Thing is, I must have watched a dozen other people play the game at DragonCon this year (the arcades there are always super packed), and none of them came close even to my meager score. Because none of them knew how to do a Crazy Dash. It was a stand-up cabinet, which didn’t have that sticker explaining how to do one.

That’s what I mean by gatekeeper information: it’s literally One Weird Trick to stellar Crazy Taxi scores and game times. Once you know how to do it your journey isn’t over, in fact I think that’s where the game starts to get really interesting, and my highest scores on the easiest difficulty are nearly $70K. But if you don’t know how to at least do a Crazy Dash, you will never get a good game of Crazy Taxi, you just have no chance. You’ll just waste too much time accelerating from a stop, and you’ll have to stop frequently to let off customers and pick up new ones. Its just how it’s designed.

There, this is a slightly more respectable score. It’s from my Youtube playthrough!

What amazes me is that Crazy Taxi was a hit, it did very well in arcades and on Dreamcast, and yet still most players never learn this information. And in a way, and understand that I’m uncomfortable with this conclusion, that’s for the best? Like how a crane game set to reflex towards a target winning percentage will be more likely not to drop a piece of plush if a lot of players have recently lost, so too are all those players losing quickly at CT allowing the designers to guard half-hour games behind a simple maneuver that, still, few players will ever bother learning. The alternative is to make the trick harder, or even not to have one, dooming everyone, the casual and the dedicated, to those pitiful 90-second games. That’s capitalism for you.

Which shows, I guess, that the illusion of being able to do better is more important to arcade game success than reality? I don’t know, I’m uncomfortable talking about illusions in a post that started out mentioning politics. But hey, Tim Walz! If you read this and want some Crazy Taxi tips, reach out! And good luck in November, please help Kamala Harris to send That Other Person as far away from public office as possible.

Once you start thinking of it in terms of gatekeeper knowledge, you start seeing it everywhere. One-hit kill action games are full of it, since the first time you encounter any enemy, it’s likely to behave in some way that will kill you. The best action games will try to have an enemy demonstrate unexpected behavior at least once before it’s likely to be fatal. And any time a game kills your character out of basic unfairness, like from a sudden unavoidable death trap, that’s gatekeeper info.

UFO 50, for all its greatness, does this a lot. The very first game in the collection, Barbuta, has an instant death laughably close to the start. Some of its games feel like a sequence of deaths you have to experience, each at least once, before you’re allowed to win. But it’s far from unique in this, and in presenting itself as the history of a fictional 80s developer, it could be argued that it’s mirroring the development of game design at the time.

Balatro University’s Beginner’s Guide to Extremely High Scores

It’s a long one today folks. To mark the release of the mobile version of poker-based time sink Balatro, let’s sit back, for two hours and 42 minutes, and watch Balatro University plot their way through the first eight antes of a game:

The video says it’s part 1 of 2, and ends after the nominal win, but the game doesn’t end there. If you want to watch the rest of the game, it’ll take another two hours and 27 minutes of your time, to get to Ante 18.

Irrelevant note in passing: the Youtube ID for this video contains four consecutive lowercase ‘u’s.

High-level Balatro is a game of extremely big numbers, and Ante 18’s requirements are along the lines of 5.53130, which in regular notation is 5,531,000,000,000,000,000,000,000,000,000. Be still my beating heart! If you just want to jump to where the game starts to get insane, try this link to a moment a little into that video.

So if you don’t want to watch five hours of video but still wan to know something of what’s going on? First off they use a lot of Purple Seals. Every time a Purple Seal card is discarded you receive a random consumable Tarot card. Tarot cards have a bunch of uses. Two of them give you money, but most of them give you some way to modify your deck. Particularly, Strength lets you increase the rank of two cards, Hanged Man lets you destroy two cards, and Death lets you turn one card into a copy of a different one.

With enough Tarot cards you can perform potent crimes against power, like turning your entire deck into a single type of card! That not only makes some poker hands, like Four of a Kind, or the secret hand Flush Five, really easy to make, but it lets you exploit certain Jokers that operate on a different card each round. These Jokers always pick one of the cards in your deck at random, but if you only have one type of card, they have to pick that one!

The most valuable kind of Joker for the long haul is one that gives you multiple Mult Multipliers, and to retrigger those multipliers. A Glass card multiplies your Mult by 2; a Glass card with a Red Seal multiplies it by 2 twice; other Jokers that retrigger cards multiply it by 2 more times.

It sounds fairly simple written out here, but setting up this system is where the skill lies. While I observe that the real game of Balatro isn’t merely in performing these ludicrous offenses to mathematics, but in figuring our how to do them, watching a really high-level player smash through its strictures and rules might give you some ideas for improving your own game, even if you don’t follow Balatro University’s techniques exactly.

Arcade Mermaid: Rampart, Part 4: Level Strategy

Arcade Mermaid is our classic arcade weirdness and obscurity column! Frequently (no promises) we aim to bring you an interesting and odd arcade game to wonder at.

Yes! More Rampart! I’m still out of town at DragonCon so I’m repurposing an old strategy guide I wrote for Extended Play into a week of posts. Even I’m starting to get sick of Rampart by now, but please stick around. And if you’ve ever tried playing this infuriating game in the arcade, this might give you the advice you need to get through to levels you might not have thought possible! And this is even a fairly short post!

Level Strategies

Level One (“Recruit”)

Castles available: 6

It’s advised not to start on this level unless it’s your first game. You’ll not only miss out of 5,000 points by starting here, but it means the beginning of Level 2 will begin you with only two cannons instead of three, and you’ll face more ships.

This level is so easy that it barely rates mention. It has six castles, and only Gunships appear. Unless you’re purposely stalling, you’ll finish this map in two rounds. Even if you stall, the level auto-completes in three rounds, regardless of if you fire a single shot.

Another reason to avoid picking Beginner is that its selection is always the “J” map, which is one of the easier selections from the initial four boards. It’s better if you pick it later, when the opposition is harder, to balance out the difficulty.

Level Two (“Veteran”)

Castles available: 5

The Veteran level is randomly chosen from one of the other three basic maps, although it tends to be the “C” map most often. Ideally it won’t be the “Hat” map, it being the easiest, as you’ll want it to be your Level 4.

If you started on the board, the first round will always put you up against four ships, one of which may be a Lander. Later ships are frequently also Landers. As a result grunts may appear on this board, but even if some appear, so long as you focus on destroying enemy ships and don’t suffer major setbacks like losing your home castle, you’ll probably wipe out the attackers before they become a huge problem.

On a later round in this level you’ll probably encounter your first Red Ship. A Red Ship tends to get off two or three shots in a round, each producing flaming crater you must build around.

Level Three

Castles available: 5

You always get to pick this level yourself. I usually try to make it “C,” “J” or “Hat,” in that order. I usually avoid picking “N,” but it’s not really harder than “C,” so pick whatever is your preference.

Much of the fleet will be Landers here, so this is the first level where you must be diligent about thinning out their numbers. Especially try to take care of ships about to land; grunts are unwelcome visitors to deal with, and it’s best if they never show up at all. In the event of a landin, which is sometimes unavoidable, try to spare a few seconds to build a barrier to them, to wall them off from the rest of the board. If you can contain them in a small area around the landing, you can keep their numbers down that way and thus reduce the number of shots you must expend in cleaning them up. Don’t think you can just let them be! They will overwhelm you easily if you ignore them.

I try to pick a home castle that’s near another castle, so I can capture them both with one wall. If you can consistently get both each round, that’s three cannons each time. Use them to connect the space between the two castles, but try to keep that space as small as possible. Try to aim for the minimum-sized rectangle needed to save both of them, and then try to place all your cannons within that rectangle.

Level Four

Castles available: 4

Now the game starts to get serious. If you can get here on your first credit you’ve done very well, but your weak basic guns will become more and more of a liability for you. Dark ships start appearing on this level, and will continue to appear until the end of the game. They all take one extra hit to sink. That’s three hits for Gunships, four for Landers, and six for Red Ships.

Try to make Landers that have a chance of landing at a diagonal shore your top priority. If one makes it through, then at the start of the Building phase devote three seconds or so it blocking their progress with walls. If they get away from the shore and a significant number appear, then focus on surviving and shoot them with cannons during Battle. Red Ships start to be a significant threat here. Once all the potential landings are taken care of, try to pump six shots into a Red Ship.

Level Five (peninsula)

Castles available: 3

Regardless of how you got here, you have a choice between two new maps for this level, a diagonal peninsula going upper-right to lower-left, or one going from upper-left to lower-right. I call these the “slash” and “backslash” maps, respectively. I usually pick backslash, but both are about the same difficulty.

These maps have the property of having two seas, a small one at the top of the screen and a more typical larger one at the bottom. The small water region is both a blessing and a curse; the restricted movement makes it easier to destroy ships there, but landings are very likely unless you clear out the Landers arriving there. What is more, these maps are the only ones in the game that break the rule about landings only being possible on diagonal shores. Landers in the small sea are also counted as landed if they contact land at the very edge of the screen, even if there’s no diagonal shore nearby. This property doesn’t extend to screen-edge landings in the larger sea.

The worst thing about these levels is that the game takes off the limiter on the number of Red Ships that can be generated each round. Red Ships here are nearly as common as Double-Sailed ones! You’ll frequently see seven or more on-screen at a time. While you must remain vigilant to prevent and/or mitigate landings, you must also work towards reducing the number of Red Ships. The large number of flaming craters on these levels made adopting a “summer home” strategy imperative, where you switch off between castles when one gets too difficult, or even impossible, to save. It’s usually a good idea to try to capture two castles in the first round because of this; then you can station some or all of your cannons for that round at the other castle, so you’re not defenseless when you’re forced to turn to it for survival. From there, you can focus on getting cannons around the third castle for maximum safety.

This level is a strong test of your Rampart skills, and often is a barrier to progression until you’ve played many games. But it’s not invincible. On Easy difficulty, I’ve passed this level still on my first credit multiple times. The biggest thing you have to worry about is the high probability of impossible situations.

Consider: when any castle is adjacent to other objects, you must capture the whole collection as a set. Chains of objects like this increase the difficulty of getting the whole thing, and increases the odds of getting an impossible save. I’ve seen this happen after even the first round on a peninsula board, and I’ve seen it happen on all three castles on one of these maps at the same time.
The only substantive thing you can do, besides rotating between castles, is to shoot some of the dangerous walls yourself. Red Cannonballs don’t leave craters if the wall is already destroyed, but that takes time and often makes for a difficult repair.

So, what if you manage to clear this map? What happens next? The game scrolls the FINAL BATTLE banner, and you get a one-way ticket to:

Level Six (island)

Castles available: 2

It all comes down to this. This level is a special kind of hell, only slightly mitigated by the fact that it seems you can get away with sinking fewer ships here, and, because you’re surrounded on all sides, your shots often don’t have that far to travel to reach a ship. There are four prime landing areas, each in one corner of the map, so landings can only be delayed, not prevented. And you only get two castles. Enjoy!

When you start looking more closely at the map, some slight advantages become apparent. There’s a lake in the bottom-left of the board, which gets in the way, somewhat, of grunts approaching from the bottom. Both castles have a good amount of land around them, although there are so many Red Ships here that the “summer home” strategy is essential to survival.

The continue limit eases up a little bit here. If you were at the maximum of four continues upon starting Level Six, the game will grant you an extra continue when you get here. (You still have to pay your coins for it though.) And also, if you were at that final credit, the game will actually downgrade your cannons one step when you get here, so get used to expending two/three/five shots for Gunships/Landers/Red Ships again. If (ha ha, “if”) you do expend that last continue, you go back to only needing one/two/four shots to sink ships. (There is more information on the effects of continues on cannon power in the notes, later on.)

This level is an ordeal, but it can be finished surprisingly quickly. I’ve seen it cleared in three rounds, although that was after several continues (it had been a pretty great game up to that point). This level is the big obstacle to one-credit clears, I’ve managed to finish everything up to it on one credit only to bang my head against it repeatedly. Using save states, I’ve managed to finish it with a single continue, so it is possible to finish it relatively cheaply, but making do with such weak cannons is a real challenge.
