The Game Boy Advance game Rhythm Tengoku contains 48 regular Rhythm Games. They are arranged in eight sets of six, with each set culminating in a Remix that combines its preceding challenges.
Released in Japan on August 3, 2006, Rhythm Tengoku was the first game in Nintendo's Rhythm Heaven series and the last first-party title released for the Game Boy Advance. Its design emphasizes listening to musical cues rather than following constant visual prompts.
The number 48 refers to the regular Rhythm Games, not every activity in the cartridge. The GBA version also includes four Endless Games and four Rhythm Toys. A common mix-up comes from Rhythm Heaven Megamix, whose much larger total includes games from several earlier entries and additional content.
