In a 2-Player game, P1 controls Mario (on the left), and P2 controls Luigi (on the right). To win, you must clear all the objects on your trays before your opponent. If you clear the screen first, you will get an egg. However, if objects pile up over the top line, your opponent will get an egg. The first person to receive three eggs is the winner.

Attacking in Challenge Mode

If you sandwich objects between an upper and lower eggshell half, they will be sent over to your opponent.
