The game board is a 9x9 grid. 48 wooden discs are laid out (on all fields except the outer rim and the center). A player's move consists of first moving one disc one field orthogonally, then jumping over any neighboring disc with any disc (there are no player colors; all pieces may be used). Chain jumps are ok, and all discs that a player jumps over are removed and counted towards the 25 victory points that are the winning condition.
