Flow Ball

Flow Ball (Japanse: ノリ玉 Norikan)[https://en.wikipedia.org/wiki/Help:Installing_Japanese_character_sets ? ] ) are pearl-like balls that can be obtained by getting a perfect in every rhythm game or clearing a challenge for the very first time in Rhythm Heaven Megamix. They can be used to buy some extra rhythm games at the museum shop instead of rhythm coins that cannot be found in the story mode. You get 1 Flow Ball per Perfect, and several Flow Balls depending on the difficulty of a challenge. A total of 144 Flow Balls is required to unlock all games.
