Tiny Chess is a great minichess implementation that allows you to start and play multiple games of minichess at once. Minichess is a variant of chess played on a 5x6 board utilizing 5 pawns and one rook, bishop, knight, queen and king per side. The back rows are intelligently semi-randomized to vary the game. Minichess is great for people who love chess but prefer shorter games, haven't mastered full-sized chess' intricate opening games or are just learning chess.
