This is a game of international chess are described here. The chess pieces are represented by arrangements of circles which indicate their movements. Pawns are single circles, Rooks are 5 circles arranged in a + pattern (indicating horizontal and vertical movement), knights are 4 circles in an L shape, bishops are 5 circles in an X pattern, queens are 9 circles in a square, and the kings are large single circles.

This version includes castling and en passant captures. Pawns are automatically promoted to queens upon reaching the back row; there is no option to promote to a different piece. There are two rule variants available in the Variations menu. "Chess256" starts with pawns randomly placed on the second or third ranks, resulting in 256 possible starting configurations. "King's Corner" places both kings in opposite corners, and randomly places the other (non-pawn) pieces on the back row, making sure the bishops are on opposite colors. There is no castling allowed in King's Corner.

The computer AI is very weak even on Hard; it only looks a few moves ahead and has no opening libraries.


Player 1 gets an early checkmate by capturing the highlighted pawn with the queen.
