PocketBalone is a port to Pocket PC of the classic Abalone, a relatively recent but nonetheless well-known board game.
The goal of the game is to push 6 out of 14 of your opponent's marbles outside the board. The rules are included in the programme but are in any event easy enough to find on the web.
At only 159 KB, this port is totally worth your attention. You can play alone against the AI, or with 2 to 3 other human players. It is also possible to make handicaps or obstacles (movable or not). In brief, all the options have been foreseen.
