In the game Horses & Pawns, the player controls a horse and needs to capture all pawns. Movement and capture happen like in a chess game. The horse moves by walking 2 squares in one direction and 1 in the other (the vertical and horizontal directions). To capture, the horse only needs to fall into the same house as a pawn. Every time the horse plays, pedestrians walk one house forward. If any pawn manages to leave the board, the player loses the game. If he captures them all, he gets 1 point and proceeds to the next challenge!
