You'll see Donkey Kong on the left side of the screen along with his trusty drum. When you play the game, a steady stream of action icons scroll in from the right. As they near a marker by your drum, you'll have to perform the appropriate action. The game has four different actions: left drum, right drum, both drums, and clapping. Some actions are also stretched out to cover a longer area, asking you to execute that action as quickly as possible for more points. If you are in time with the song, you do well and earn points. Missing the cues eventually causes you to lose the game.
