I’m not going to say that famously Ms. Pac-Man is a more random game than Pac-Man, because who really knows things like that who isn’t a hardcore gamenerd. But among hardcore game nerds, it’s common knowledge. (If you didn’t know, A. congrats on your coolness, and B. sorry to now destroy your coolness.) Here a video about how randomness works in that game, from Retro Game Mechanics Explained (21 minutes):
Pac-Man is a game that is vulnerable to patterns: if you do exactly the same thing each time on the same level, the same results will occur. There is one pseudo-random element in Pac-Man though: when vulnerable ghosts reach an intersection, the code picks an arbitrary address from a range of memory addresses, then uses that value to pick a direction to decide which route to take. Two implications of this: vulnerable ghosts are most likely to head left at intersections and least likely to go up, and if any byte in that range changes the behavior of the game slightly changes too, even if it’s not an executable byte. Patterns still work in Pac-Man, despite this pseudo-random function, because the seed is reset at the start of every level, so if you do exactly the same thing, vulnerable ghosts will still have the same information fed to their movement routines.
Ms. Pac-Man has other sources of randomness: the ghosts, in Scatter mode, use a different source of pseudo-randomness to decide where to go, one that isn’t so easy to manipulate; and which fruit appears and which of four predefined routes (three for one of the mazes) it’ll take through the board.
Ms. Pac-Man doesn’t have its ghosts scatter periodically through the level like they do in Pac-Man. They only scatter at the start of the board. It’s not much randomness, but it’s enough to upset rote pattern creation, since each ghost has the opportunity to make several decisions of which path to take during that period. The way the randomness is handled is interest itself. The ghosts pick one of the corners of the board, much like they would in original Pac-Man, but randomly, when making their choice of target to home in on.
So there! Now you can amaze your friends, if it were 40 years ago and your friends were then able to be impressed by your knowledge of Ms. Pac-Man! You’re retroactively welcome!
PacStrats on Youtube has a video that gives three patterns that will take a casual player all the way to the kill screen at level 256.
I say casual because this doesn’t attempt to produce a “perfect” game, of 3,333,360 points. This is because it doesn’t attempt to eat all four ghosts on every Energizer while that is possible. It actually ignores the ghosts when they’re vulnerable. There are patterns for that on PacStrats too, but you’re not going to be able to do it by memorizing just three patterns. You can really push your personal limits, and that of your free time, trying to get better at video games, and most of us have a point where we have to say that’s enough, and then go and read a book/buy groceries/have sex/something else. The three patterns in the video below are a nice middle ground.
It isn’t easy to devise a Pac-Man patterns, and it’s much harder to come up with a small number of patterns that cover all the levels. Patterns work because the movement of the ghosts is completely deterministic, depending on how Pac-Man moves. If you can move Pac-Man with frame-perfect accuracy, then the ghosts will oblige you by always responding in the same ways. The frame-perfect requirement is eased up a lot by the nature of Pac-Man’s motion. So long as you don’t reverse directions or delay, Pac-Man can only change direction at intersections. So long as you have the joystick, or whatever ludicrous controller setup you’re using, pressed in the direction you want to go next three frames ahead of the turn, your gluttinous circle’s progress will be on track for that pattern.
So, if you try to perform a pattern and it doesn’t work, what went wrong? Most commonly it’s because you hesitated at some point, failing to make a turn at least three frames in advance. Sometimes that’ll be okay, but two of the ghosts, Pink (Speedy/Pinky) and Blue (Bashful/Inky) use the direction that Pac-Man is facing in their AI calculations, and that can change much more rapidly compared to his location in the maze. Even being a single frame off in your timing can produce a situation where Pac-Man will be facing a direction that will cause them to take a different path at a choice. Also, some of the motion of the ghosts is determined by the amount of time that’s elapsed in the current level, and if Pac-Man’s in a subtly wrong position then it can be disastrous later on.
The periods over which the patterns are good are the first four levels (Cherry to second Orange), levels 5 through 20 (first Apple through to 8th Key) and from 21 onward (9th Key to the kill screen). The actions of the ghosts are not the same throughout the run of each pattern. The second pattern, in particular, works over so many levels mostly because its creator, through trial and error, happened upon a pattern that’s good for so much of the game. Because the travels of the ghosts will be different on different levels, it’s important not to get spooked because they are moving differently than they did on previous levels. So long as you move Pac-Man through the patterns assuredly, without delay, and at least three frames in advance, then he’ll clear the boards in succession for as long as you care to keep going, until level 256, where Pac-Man’s All-You-Can-Eat buffet closes its doors.
Unfortunately, PacStrats has made their pattern video non-embedable, so if you want to see these patterns in action you’ll have to click through to the video’s Youtube page.
From the linked page. Piranha is one of a whole category of Pac-Man bootlegs that try to obscure their origin.
I’m considering writing more on the subject of the male-gendered Pac, which I assume is a mere matter of social custom among the Pac-People since they have no genitalia or clothing. Pac-Man bootlegs, in particular, are bizarre and wonderful, even if they often aren’t very fun to play.
But Cam has a nice page devoted to Pac mutants. And these old Geocities-style pages need much more love these days, so for now I’ll link to them. Have a look!
A little remarked-upon aspect of these Pac-legs is how their character name is strictly determined by how many letters long it is, so that they can fit on this screen in the same amount of space that PAC-MAN did.
If it’s generally entertaining, I try to save game-related animations and cartoons for Sundays, but this is probably interesting more for how it illustrates how the Pac-Man propery is changing. Yes, it’s another excuse to rant a bit about how Pac-Man’s lore is changing under Namco’s direction, like in the Baby Pac-Man post!
I recognize that Bally/Midway’s taking the lead on Pac-Man promotion and lore amounted to a bit of cultural chauvinism. In the early 80s, U.S. licensors of Japanese arcade games would outright put their own copyright notices on games. When I was a kid and Pac-Man fever was running at 104 degrees (Fahrenheit), I knew that Bally/Midway was a thing that existed, but nothing at all about Namco. They filled that widespread ignorance of the game’s origins with their own lore, starting with Ms. Pac-Man, and it’s surprising that now, long after their deal was dissolved and Midway games division consumer games division shut down, that their lore survived for so long.

A lot of that has to do with the enduring popularity of Ms. Pac-Man. Other Bally contributions like Jr. Pac-Man haven’t proven nearly so enduring. Another part of the U.S. Pac-Man lore, that has ended up exerting a strong, almost unhealthy, influence over their property has been the Hanna-Barbera cartoon show, yes the one almost no one remembers except for its weird Christmas special, from 1982. That thing got two seasons, alongside likewise forgotten (and less durable) properties Richie Rich and The Little Rascals. H-B’s version of the characters continues to pop up randomly in different places, like the cover art for the original version of Tengen’s release of Pac-Man for NES.
The Hanna-Barbera cartoon was a strong influence over the art design and music of Pac-Land, which means among other things that that weird cartoon is now echoed in Smash Bros. Ultimate. Shh! No one tell Warner Bros!
Okay, time to spiral on down to the point of this post. A “pop-up store,” it seems, is a “retail concept” that involves setting up a small store for a limited period of time, often with a strong theme or a focus on a single brand. Kind of like a micro-sized version of Spirit Halloween.
Namco experimented with a Pac-Man-themed pop-up store in Japan in 2016. They called it “Pac-Store,” and they came up with its own idiosyncratic take on the Pac-Man lore for it, and made a series of short web cartoons to promote it. They’re still on Youtube, but they’re collected into one video by The Pac-Man Archive. That’s what is embedded below. Even though it’s mostly in Japanese you should watch a few minutes of it, if just to see how Namco has retconned the history of the hungry yellow sphere.
Like gag me with a spoon, it’s Pac-Marie! I love the Pac-gloves on this style of character.
From Ghostly Adventures: Pac-Man and friends who I don’t even care enough about to learn their names. UGH. That’s a lot of detail spent on the idea of Pac-shoes. Image from Gamespot.
Pac-Man has two assistants, but they’re not Ms. Pac-Man or Baby or Jr. They don’t even have “Pac-Mom,” Namco’s more-recent recreation of Ms. Pac that isn’t burdened by AtGames’ licensing with Ms. Pac-Man creator GCC. Instead, Pac is backed by “Pac-Marie” and “Pac-Little.” Keep in mind that the horrible “Pac-Man and the Ghostly Adventures” TV show was released around 2013, and its characters got unfortunately crammed into at least one iteration of Pac-Man Museum (the one I have on Steam). It’s interesting that they didn’t use those for Pac-Store. Maybe Namco was already coming to realize that Ghostly Adventures was destined for purgatory.
I actually don’t hate Pac-Marie, she’s got a fun design, and it’s not like Pac-People have much to distinguish them anyway. She’s still a hell of a lot more appealing than anything from Ghostly Adventures.
Over on Mastodon, Dan Fixes Coin-Ops has been documenting an epic quest: the repair of a Baby Pac-Man machine.
It’s one of the non-Namco Pac-Man spinoffs that Bally/Midway released in the wake of the original’s extremely high popularity. I’d like to remind readers that while Namco has been the sole beneficiary of Pac-Man’s heights lately, the original game, at first called Puck-Man in Japan, was not popular there. The spin-offs, console ports, handheld games, trading cards, stickers, clothing, cartoon show, Christmas special, breakfast cereal and unnumbered other items, that was all Bally/Midway’s doing. Toru Iwatani created and designed it, his team made it into a game and cabinet, Namco released it in Japan to middling success, and from there Bally/Midway got behind it and turned it into one of the most gigantic video game hits there’s ever been, a machine that at one point had one hundred thousand units.
Now, I’m not going to deny that their effort led to some erasure of knowledge of Namco’s existence at the time. All those Pac-Man machines and spin-offs mentioned “Bally Midway Mfg. Co.,” with nary a mention of Namco. But it’s undeniable now that erasure is happening in the other direction: a search over the History page on official Pac-Man website has no mention of Bally at all, even though the page acknowledges that the game was “a major hit in the United States.”
Some of that success leaked back to Japan and fueled some Namco-made sequels: Super Pac-Man, Pac N Pal, Pac-Land, Pac-Mania, Pac-Man Arrangement and eventually Pac-Man Battle Royale and Pac-Man Championship Edition, and more recently things like World’s Largest Pac-Man and Pac-Man Battle Royale Chompionship.
Bally/Midway made their own sequels. One of those, Ms. Pac-Man (created by GCC), came to eclipse the original in popularity, but in addition to their licensing of Super Pac-Man and Pac N Pal they made Jr. Pac-Man (also from GCC), as well as Professor Pac-Man and this game here. The one Dan Fixes Coin-Ops repaired. Baby Pac-Man.
Baby Pac-Man is a game that only could be made by Bally, because it’s a video game/pinball hybrid.
Bally, together with the company that would buy them, Williams, is arguably the greatest pinball maker there’s ever been. Up until around 2000 (a heartbreaking year) they made wonderful machines like The Addams Family, Twilight Zone, Attack From Mars, Star Trek: The Next Generation and quite a few others. In 1982 though pinball was in a slump while video games had reign over arcades. The decision to make a game that connected one of the greatest arcade games of all with pinball must have seemed obvious. (It wasn’t their only attempt to capitalize on their golden license with a pinball table, witness Mr. & Mrs. Pac-Man, which I’m informed was released eight months before Baby Pac-Man.)
The combination of an arcade video game and pinball makes for a unique experience. It also makes for a game which breaks down even more often than your standard arcade game, as the thread notes: there’s three computers in the thing, and it’s subject to all the typical arcade game problems, all the typical pinball problems, and special problems with the portions of the machine that connect the two halves together.
The thread begins memorably:
In case y’all were tired of hearing about popular Fediverse people making bad decisions, just thought I’d let y’all know I bought a 1980’s hybrid pinball/videogame tonight
Like this isn’t for a client, I’m not working on it to earn. This game COST money. This is my game now, I paid for it and it lives in my house. I’m not gonna get to give anybody a bill.
This is such a perversion of the natural order of things. I’ll probably route it one day, but for now this is an arcade machine that I SPEND money on!
It’s taken me a little while to get it into the house and have a chat with the mate who sold it to me and let the littleun have a go and put her to bed and fix a couple things and have a go myself so I’ve not been catching up on my notifications, I saw some questions so I’ll do a little thread on it over the next couple of days
I cannot stress enough that you should not buy one of these things
Folk who like 80’s pinball want stuff like this or Haunted House and you shouldn’t buy a Haunted House either
These are games for pinball techs or people with money to hire pinball techs or very close friends of pinball techs
Except Baby Pac-Man needs you to be friends with an arcade tech too.
He finally got it working after three months of work, and what a journey it is. He did it for love of the game: while Baby Pac-Man is dissed in some circles it’s a genuinely interesting game. But to like it, you have to abandon the relatively lenient expectations of classic arcade video games. Pinball is inherently unfair, and that unfairness oozes out and coats even the video portion of Baby Pac: the ghosts don’t waste time in coming after you, and you start with no Energizers: you have to earn them in the pinball portion, which for the most part you can only visit once per life/board. You can return to the video portion temporarily though by locking the ball in a scoop.
Here is the full thread (to date) in Masto Reader, which is a Mastodon version of Threadreader. It takes maybe half a minute to collect the posts and present them though, so to read the whole saga you’ll have to be a little patient.
An interesting video about Baby Pac-Man (although with some bad sound) District 82 Pinball’s here (12 minutes), which covers the tech and gameplay:
In this video from four years ago, top-level Galaga player Jordan Dorrington gives us advice for how to get far into the venerable arcade classic.
Some of the tips given:
On the first level, enemies never shoot as they enter. Shoot as many of the bugs as you can as they enter the screen.
Boss Galagas never try to capture your ship if there’s only one remaining.
On the first two Challenging Stages, if a double ship is positioned exactly in the center of the screen, you can stay there to shoot the bugs fairly easily and get an easy Perfect.
Starting from Stage 4, some extra will be among the ones that will swoop around entering formation, and will leave the attacking ranks to rush you.
After the first three stages, the game settles into a pattern of four stages. The first three stages of each set have distinct patterns, followed by a Challenging Stage.
The first stage in each set of four has the bugs entering in two mirrored processions from the sides of the screen. The second stage has them entering from one side in double rows. On the third stage they enter from the side in one long string.
Galaga kill screens are difficulty dependent. There’s a game-ending screen on difficulty levels (or “ranks”) A and C. The other difficulty levels loop and continue indefinitely
Basic strategy for cleaning up the remaining bugs is to start at one edge of the screen, and as they fly down at your ship, to move towards the other side a tiny bit at a time, to avoid the shots coming at you, and shooting to eliminate as many of the bugs as you can in the process.
If you survive a long time on a single wave, there’s a well-documented bug in the code that causes the enemies to shoot less and less, and eventually cease firing completely. In casual play that’s great, but Twin Galaxies rules are that you cannot take advantage of this bug intentionally.
If you get really good at Galaga, it’s best to play as Player 2, as the first player’s score rolls over after six digits, but the second player’s score records seven digits.
The game’s difficulty stops increasing at Stage 31.
If you’re playing on a difficulty without a kill screen, after Stage 255 you’ll progress to Stage 0. It throws many players off in that the bugs travel at the slowest speed, but their shots are extremely rapid.
The hardest part of the game is recovering from losing a double ship. The game is much harder in single ship play.
