Each player tries to position his spheres as accurately as possible. During each game round, six task cards are revealed. These cards indicate conditions you must follow when placing the spheres—for example, which spheres must not be on top of other spheres or must not touch each other. If you complete the tasks correctly, you receive points, and if you have the most points at the end of the game, you win! A jaZams favorite! For 1-4 players. For ages 8 and up.
