Rhythm Heaven Megamix

Rhythm Heaven Megamix, also known as Rhythm Paradise Megamix in Europe and Australia, Rhythm Tengoku: The Best Plus in Japan, and Rhythm World: The Best Plus in South Korea, is a rhythm game released for the Nintendo 3DS in 2015 in Japan, Hong Kong and Taiwan and 2016 in the rest of the world, and the fourth installment of the  series. The game largely consists of games taken from past installments, along with handful of new ones. Like previous installments of the series, Rhythm Heaven Megamix is a collaboration between Nintendo SPD1 and Japanese song producer (also known as Tsunku♂).

While the WarioWare  series and the Rhythm Heaven series have made occasional references to each other in the past (most prevalent in Game & Wario) due to being developed by the same team, Rhythm Heaven Megamix solidifies the link between the two series by including a set of challenges featuring the cast of the WarioWare series.

Gameplay
Rhythm Heaven Megamix is a rhythm game tasking the player to play through a series of rhythm-based minigames played using the button, the  button, and the. Rhythm Heaven Megamix alternatively offers a tapping control scheme using the, although it does not replicate the more elaborate touch screen motions from Rhythm Heaven for the Nintendo DS. Unlike other rhythm games, Rhythm Heaven Megamix has a stronger emphasis on testing the player’s sense of rhythm and will often subvert the visual cues during the course of the minigames, just like the previous installments in the series.

Rhythm Heaven Megamix is composed of 108 minigames: 78 taken from past installments, and 30 brand new. In the early portion of the game, some of the returning minigames have been altered to be easier and feature new graphics and music, while their original forms later appear as sequels.
