Success involves mimicking the patterns shown, contributing to a shared score as both players work together. The gameplay focuses on cooperative play; two people must coordinate their actions to achieve high scores and advance through the game’s music selection. It is considered part of Namco's instrument-based arcade games released during that period. This version, designated UL1/VER.A, represents the initial release of the title in Japan.
