The following variant makes use of the fact that there are red pieces as well as a red center and red cards. The player in charge of the red pieces has a job that differs from that of the other players. While the other players must try to move their spheres to the "Bull's Eye", it is the red player's job to prevent them from getting there. This makes "Geometry Strategy" an asymmetrical game. The red player wins if at least one player (including the red player) has lost more than half of their pieces, irrespective of how this has happened. It may therefore not be wise to remove too many red pieces from the game. The non-red players can try to prevent this by cooperating. The non-red player however whose sphere enters the "Bull's Eye" wins the game. Removing the red sphere from the game may be easy but it brings the red player closer to victory as the red player wins automatically if a player has lost more than half of their pieces. Losing the red sphere does NOT make the red player lose the game. The red player is the only player allowed to continue playing without a sphere. The red player must try to defend (and NOT conquer) the "Bull's Eye". All other rules apply. Comments?
