Simon Tatham’s Portable Puzzle Collection – Games for the Brain

Simon Tatham’s Portable Puzzle Collection

I recently published an article identifying 13 fun open source puzzle games. Each game is worth downloading. As a reader pointed out, the article didn’t include an exquisite puzzle collection. That’s Simon Tatham’s Portable Puzzle Collection. Let’s call it the Puzzle Collection for brevity.

Every game in this Puzzle Collection is published under an open source license. And the collection is portable. What does that mean? Well, the games run on almost every modern operating system. Besides Linux, Windows, Mac OS X, you can play the games on anything that supports Java, or JavaScript. They can also be played on the web.

In fact the portability of the games are one of their chief virtues. You can be just about anywhere, on any combination of hardware and operating system, and indulge in a few minutes of puzzling. That’s the lead developer’s intention. These games aren’t intended to hog the whole afternoon. Instead, they are great to dip into when you need a brief diversion from whatever you are meant to be doing.

Many of the puzzles are not invented by Simon or any of project’s other contributors. A number of the puzzles were invented by Nikoli, a Japanese publisher that specializes in games and, particularly, logic puzzles. There are some classic puzzles included in the Puzzle Collection. Implementations of quintessential puzzle games like Master Mind, Sudoku, and Minesweeper are featured. And there are lots of small puzzles that most people will never have played elsewhere. The diversity of the collection makes it a treasure trove.

Here is a short video demonstrating Guess (Master Mind), Inertia, Tents, Mines (Minesweeper), and Solo (Sudoku).

Besides the 39 puzzles below, there are a few unfinished puzzles lurking in the project’s repository including implementations of Block Puzzle (another puzzle invented by Nikoli), the block-sliding puzzle ‘Klotski’, and the well-known Sokoban barrel pushing game. There’s also a puzzle called Group which is, in fact, complete. It’s a Latin-square puzzle, but played with groups’ Cayley tables. You are given a Cayley table of a group with most elements blank and a few clues, and you must fill it in so as to preserve the group axioms. It’s not included in the puzzle collection because Simon considers it too esoteric and hard. But it’s easy to compile at least.

Below is a short tutorial showing you how to download and compile the latest source code for this game, and the other 38 games in the puzzle collection. The tutorial takes place in Linux, using the Ubuntu 17.10 distribution, but the procedure will be the same, or very similar, for other Linux distributions.

If you find the videos helpful, please give them each a like and subscribe to our YouTube channel.

Besides the main 3 operating system, the puzzle collection has also been ported by contributors to Palm, Android, Symbian 60, iPhone, iPad, and the Windows Store.

    Great writeup. I like that you threw in there some more of the background that I wasn’t as familiar with
    Thanks for throwing this in here.

    As I mentioned in the other blog post, each puzzle is procedurally generated, so there’s an unending supply of new puzzles to do.
    Some of the puzzle games have varying levels of difficulty (besides the size of the grid) which may range from trivial to mind-bending.
    There are also no high scores, no timers, no push to finish-as-fast-as-you can or to beat-your-previous-best, so they’re great to just leave up in the background somewhere for when you have a couple of minutes to kill or for when you want a challenging puzzle to work through or think about without the pressure of a timer ticking off the time you’ve spent.
