Push

Push is played on a 15X15 square board with each player having 10 stones. Pieces move one as a chess king, and a player has three moves on a turn. There must always be a one place buffer between opposing pieces. When a piece is moved next to an opponent piece it is pushed away one space to create the buffer. If a piece is pushed into another piece, or the side, it is captured. A player loses when they are down to one piece. Push was an entry in the THE THOUSAND-YEAR GAME DESIGN CHALLENGE
