The object of the game is to get the ball to your opponent’s last line before your opponent gets their ball to your last line.
To get the ball to your opponents’ last line, you can pass the ball in a straight line or diagonally to a player already on that line. Or move the player with the ball directly to the last line.
Each player takes it in turn to move their players’ two squares each go, followed by an optional pass. You may move one player two squares or two players one square.
