Foursies is a board game where each player, black and white by default, has four pieces on opposite ends of a chequered board. Pieces can move in any direction, including diagonally, by one square per turn. The objective is to either get a piece onto the opponent's end of the board, or capture all their pieces by hopping over them. If a piece is primed to capture an opponent's piece, it is compulsory.
