The game board has to be assembled with 4 parts to create a big 3D arena. The race track has twenty-eight boxes of which sixteen are risky: firing a crossbow may shoot a pawn in it at any time. The same bow determines, according to the box where the ball comes from, how many spaces you advance. In turn, the player must skillfully position the crossbow to try to remove an opponent's pawns lying on its trajectory. Then he moves his pawn the number indicated by the ball.
