HellChess (Amiga) has been updated to v1.2 This version can play six different games, and unlike the windows version you don't have to register the program before you can play all of them. (Amiga gift)
The games HellChess can play are: Chess, Checkers, Othello, Chinese chess (Xiangqi), Japanese chess (Shogi), Connect4
The game rules are explained inside the game, so you can start playing the new games without buying books to learn them.
