Gtkboard is a board games system. It implements all the common aspects of board games, such as the user interface, move parsing code, AI and file format. Games are fitted in as plugins. Currently more than 30 games have been fully or partially implemented. Some are single player and some are two player games. The user can play with the computer or with another person. It supports infinite undo and redo of moves.
