The gameboard is a 15 x 7 grid. Each player's territory consists of the last six rows opposite the opponent. Each player places one's own six playing pieces according to the diagram in the rules.

To win the game a player must capture all the opponent's playing pieces by landing on them thereby capturing them or score five points by penetrating the opponent's territory with one's own piece and returning.

On one's turn, one rolls two-four sided dice and moves one playing piece. A player moves one piece orthogonally and is allowed only one ninety degree turn. A player may U-turn only after penetrating the opponent's territory.
