From the rulebook:
A dexterity game for children and adults alike. Players flip small cone-shaped paper "cups" from a hand-shaped lever, trying to land them inside a net in a space that will afford them the most points. Scores are added using the points grid in the net.
The player with the highest number of points in a pre-determined number of rounds, or the player who first reaches a pre-determined score, is the winner.
