Polyrhythm

Polyrhythm (ポリリズム) is the 4th Rhythm Game of Stage 4 (22nd overall) in Rhythm Tengoku.

The arrange version, Polyrhythm 2, appears in Last Technician in Rhythm Tengoku.

Gameplay
This game is structured on a grid with two pathways, the upper path labeled 十ボタン (+ Button), the lower labeled Ａボタン (A Button). 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, Akai Mono roll out, requiring the player to repeat the given pattern using ✚ and Ⓐ for the upper and lower row respectively. After the pattern is repeated, a new one is tapped out. The patterns sometimes vary between paths.

Trivia

 * This game appears to have inspired multiple aspects of Built to Scale in both Rhythm Heaven and Rhythm Heaven Fever, such as the general art design. Thus it can be considered a predecessor of those games.
 * This is one of the few games that doesn't feature a Practice.
 * It did, however, get a tutorial in the arcade version.
