The game is played in a room, called a 'cell', 60 by 80 by 20 metres in size.

Each player controls a bat at opposite ends of the cell and the object of the game is to use the bat to prevent the ball hitting the wall behind.

Play begins with player one tasking a 'service', a free strike at the ball and continues until the ball strikes the wll behind one of the players.

The opponent then scores 5 points and the losing player restarts the game with a 'service'.

Play continues until one player reaches a score of 35 points. This player is the winner.

You can play at various speeds, from adagio (slow) to vivace (fast). You can also change the computer's skill level or choose to play against a human opponent.
