The player controls Mickey Mouse whose task it is to catch eggs as they roll down four slopes, two on either side of the screen. If an egg is dropped it lands on the floor releasing a chick who walks away off screen. The eggs fall ever more quickly as the total caught closes in on multiples of 100.
