— Polyrhythm Description (Rhythm Tengoku Arcade)
Polyrhythm (ポリリズム,Polyrhythm?) is the 22nd minigame in Rhythm Tengoku. It features the Red Things that roll around and bounce on an assembly line. A sequel appears later on called Polyrhythm 2.
This game is structured on a grid with two pathways. Before the player starts, a rhythm is tapped out, using a bass drum to represent the lower path and a snare drum to represent the upper path. After this finishes, a rod will roll out , requiring the player to repeat the given pattern using the D-Pad for the top row and A button for the lower row. After the pattern is repeated, a new one is tapped out. The patterns sometimes vary between paths.
D-Pad: Bounce Rod (Upper Area)
A: Bounce Rod (Lower Area)
Hit: The rod bounces to the next block.
Barely: The rod bounces on. A barely counts as a miss.
Miss: The rod lands on the ground and explodes.
