Simon Tatham's Portable Puzzle Collection is a popular collection of small one-player video puzzle games for PCs written by Simon Tatham and others, using a framework written especially for portability to other platforms. Some of the games are original but most are re-implementations of existing game concepts, such as Nikoli puzzles.

Due to the nature of the collection framework, any game written using the simple game API can be ported to many platforms without modification. There is extensive documentation for developers of both games and "frontends". As of April 2008 there were 27 separate puzzles in the collection, not including variations and the multiple difficulty levels within each of the games.

The official site hosts versions for Microsoft Windows and Mac OS X, and provides source files for compiling the software for Unix using GTK+. The collection is free software published under an MIT License, with ports being having been developed for the Palm OS, Windows Mobile, GP2X and Nintendo DS homebrew (as Puzzlemaniak).

[edit] Presentation

Each game in the collection runs in a window using 256 colors. They use standard controls but some vary from game to game. Every game includes undo/redo functionality as well as load/save. Most, but not all, of the games include a solver that will show the solution to both generated and hand-entered puzzles.
