Drummer Duel (応援団,Ouendan?, "Cheering Party") is the 18th minigame in Rhythm Heaven. The player controls the blue drummer who is competing against the 'red team' in a taiko duel. Getting a perfect on this game earns the gift "Cheering Tips" in the Café.
The blue drummer must copy every beat the red drummer makes during his turn and must perform it correctly in the same rhythm as him. The red drummer's speed in rhythm gets gradually faster near the end of the game.
Tap: Beat drum
Hit: Yellow stars emit from the drum. The cheerleaders will cheer the player on at the end of the turn.
Miss: Black sparks emit from the drum. The drummer will have an embarrassed look on his face. The cheerleaders will stumble over.
The chanting heard in the background "Don! Doko! Don!" is Japanese onomatopoeia used to represent impact sounds (like drum beats).
In the Korean version, they were changed to "Doong" (Korean: 둥둥!).
In the Japanese version, the "You" sign is colored black with a white outline, while it is colored white with a black outline (like in almost every other game) in the other versions.
Although the drummer on the left isn't playable, he still has sprites for making a miss. The cheerleaders on the left side also have sprites for tumbling over.
Additionally, there's sprites for what appears to be an announcer, who points to the currently playing drummer, reacting to the player's performance the same way as the cheerleaders. However, this character doesn't appear in the game.
