Labyrinth is the classic game where you control a steel ball by tilting a wooden labyrinth. It is available for iPhone/iPod touch and Android. The full version of Labyrinth has over 800 levels and is controlled by the accelerometer with high accuracy. Labyrinth has been downloaded more than 5 000 000 times (Yes, 5.0 million!)
Chess for Android consists of a chess engine (derived from BikJump) together with a GUI (thanks to Joseph Wain for designing the chess graphics). The application accepts moves through the touch screen, the trackball, or through the keyboard (viz. e2e4 pushes the king pawn, e1g1 castles king side, etc.)
The Puzzles package contains a collection of 27 small one-player puzzle games, which were initially developed by Simon Tatham for Unix, Windows, and Mac OS X.
The actual games in this collection are re-implementations of many well known classic puzzles
