The four toy-sized characters appear in a small container surrounded by other toys in a playroom; the container's floor features an 8-bit Mario from Super Mario Bros. Hovering above their heads are four Fly Guys carrying a basket filled with numerous balls in each player's color. As the Fly Guys hover out of sight with the basket, the four players each spread out to a corner of the container, and the game begins.
The Fly Guys dump the basket of colored balls into the container. Each player must collect all 50 balls of their own color as they bounce around. Players can jump on their opponents to slow them down temporarily. The first player to collect all 50 of their balls wins. If no one collects 50 of their balls within five minutes, the game ends in a tie.
The winner is shown standing alone in the center of the container, celebrating as the Fly Guys dump a basketful of confetti over them. In the event of a tie, all the characters will sulk instead.
