Abalone

Abalone is an unofficial port of the board game of the same name to Atari ST computers with monochrome monitors.

The players move up to three marbles at a time, setting them on pegs arranged in a hexagonal shape, trying to push each other spheres out of the board. The opponent's marbles can only be moved when a certain alignment is achieved, where the player spheres are in specific superior numbers like 3 to 2, 3 to 1 or 2 to 1.

The game feature single player games with three different AI players, as well as a two-player hot-seat mode. Moves can be taken back with an Undo function. The game can be started on the default board or on a randomly created position.
