We love it when we find weird and unique indie games to tell you all about! Our alien friends to the left herald these occasions.

Primesweeper is a recreation of Minesweeper, but with two changes:

• You can’t mark squares where you think there are mines. This isn’t as bad as you’d think it would be, partly because…
• All the spaces have three digit numbers on them, and the mines are hidden by the spaces with prime numbers.

Don’t let the math terms scare you, it’s not as hard as you’d think it would be, at least if you know a trick to determining divisibility by 3: the sums of the digits of all numbers that add up to 3 are themselves divisible by 3.

Primesweeper is from vole.wtf, created and filled with things made by Metafilter member malevolent, who has made many a free wonderment and entertainthing to enjoy. If you enjoy Primesweeper (or even if you don’t), I’m sure you’ll find something else fun on their website.

A generation of Windows users spent time productively by running Minesweeper, a standard inclusion with Windows from the days of Windows 3.0 through Windows 7, until they decided that it Must Be Monetized, and switched out for a free-to-play, ad-riddled version of the loathed Microsoft Store, just one of thousands of little crappages that have made up, and continue to comprise, the enshittification of tech.

Well, there are other ways to play Minesweeper that don’t require tithing your attention to the marketing department of Microsoft. An open-source version for many platforms is included in Simon Tatham’s Puzzle Collection, a collection that’s playable for many platforms including web browsers, and which is still one of the great unknown treasures of the internet. (If you’re running Linux, you might be able to find it in your distribution as Mines.) There’s another free version for Linux and Windows called LibreMines that can be found on Git, and KMines for KDE.

In the past week there’s been released on itch.io a fantasy version called Dragonsweeper, which has several interesting innovations. It was inspired by Hojamaka’s Mamono Sweeper (Japanese), as as Hempuli’s Mamono Mower. Hempuli (the creator of Baba Is You and a whole host of Sokoban-inspired puzzles) also made Cavern Sweeper, which I believe I’ve linked to before.

But probably the ultimate in this category is still the 12-year-old Desktop Dungeons, which is commercial but well worth it, and its 3D remake Desktop Dungeons Rewind.

Every game linked here is worth it. To call one out specifically, Desktop Dungeons has great depths that’ll take you many play sessions to uncover.

All of these games involve hidden terrain that hides things that are dangerous, but let you deduce their position using clues in the squares. Many of them let you fight back against those things, if you manage the level of danger you face. Desktop Dungeons changes that a bit by letting you see monsters freely without danger, but also making unrevealed squares themselves a resource that you must manage, since exploring them helps you up and restores your magic, but at the cost of also healing any monsters you’ve wounded without killing them.

Dragonsweeper is current quite the indie darling. It hides both monsters and mines in the unrevealed squares, although the mines are worth 100 threat points each so their numbers can’t be confused with those of the other monsters. It also has special generation quirks for several of the monster types, and once you understand them it makes the game considerably easier (although, like classic Minesweeper, once in a while you’re still forced into guessing).

There is a complete solved playthrough of Dragonsweeper on itch.io’s Youtube channel (11 minutes), but for a change I’m not going to embed it, as it will probably spoil some of the finer points of playing it, and in a real since, learning how to play a game like Dragonsweeper is the real fun of it, and not just the execution of a strategy that’s handed to you. So go and try it yourself, and don’t sweat the inevitable lost games! You’ll be picking up essential information for when you do start winning, and besides, losing reveals the whole map, and that has much to teach you about how the monsters hide.

You can get all 10 books for $25! It’s gone up lately but it’s still really worth it! All of the books have no DRM and can be read in most any reader, including Amazon devices! They can read EPUBs now! At last finally surprisingly at this late date!

StoryBundle is a wonder, they always present so much interesting stuff. I’m rather surprised they keep asking me back, so I try to make my own weird little contributions to it worth your while.

The board on the left is a Sudoku-like game; the board on the right is Minesweeper. The two boards match: the numbers on the Sudoku board are the number of mines in the matching area of the Minesweeper game. You use each to help you solve the other!

It’s not perfect, mind you. There’s currently no way to mark a square that definitely has a mine in it, just the question marks you see in the right-hand board above. There are still cases, familiar to players of standard Minesweeper, where you end up having to guess. And don’t click the “change size” button if you care about the current game: it doesn’t make the boards larger, it starts a new game with bigger Minesweeper and Sudoku boards!

Still though, I have to give creator Rianna Suen props for a cool idea! I found this through the “map obelisk” area during Roguelike Celebration, which is a pretty cool place to find things beloved of clever people!

I got a treat for you people today, a genuine treasure of the internet, a collection of forty computer-generated puzzles of wide-ranging types, from Sudoku (called “Solo” because of trademarks) to Minesweeper. And they’re not only all open source and free, they’re free for many platforms. Not all the puzzles are yet available for all platforms, but it’s continually being worked on, with new puzzles added from time to time. It has been for nineteen years; when it got started it only had five puzzle types. It’s one of the best things out there, and I’m amazed it’s not better known generally.

I can’t overstate what a wonder this collection is. All the puzzles are their own executable, if you don’t just play them on the web anyway. Each one of these puzzles offers many hours of happy puzzling. My own favorites are Loopy, Slant, Bridges, Dominosa, Galaxies, Net and Untangle. Most of the puzzles are of a type that should be familiar to fans of the Japanese puzzle magazine Nikoli, but they’re all randomly generated, and playable on multiple difficulty levels.

If the name Simon Tatham sounds familiar, he’s the guy who also created and maintains the popular networking tool PuTTY.

Here’s the links, all of these are free:
