Rhythm Heaven Megamix

Rhythm Heaven Megamix, known as Rhythm Paradise Megamix in PAL regions and Rhythm Sesang: The Best Plus in Korea, is a rhythm game developed and published by Nintendo for the Nintendo 3DS. It is the fourth game in Nintendo's Rhythm Heaven series, following Rhythm Heaven Fever (2011) for the Wii. The game was first released in Japan in June 2015, and in North America, Europe, Oceania, and South Korea throughout 2016.

Rhythm Heaven Megamix is primarily a compilation of over 100 rhythm minigames from the series' previous entries—Rhythm Tengoku (which was Japan-exclusive), Rhythm Heaven, and Rhythm Heaven Fever—as well as 30 new ones. Unlike previous entries in the series, Megamix features a story, where the players' objective is to rescue Tibby, who had fallen to Earth World, and bring him back home to Heaven World, passing through various sets of rhythm games to make their way back. In addition to the main story, the game features additional game modes such as the Challenge Train, which contains a selection of rhythm minigames with twists and faster paced gameplay, including stages with WarioWare-themed minigames. Longtime series composer Tsunku returned to compose music for the game.

Rhythm Heaven Megamix sold at least 1 million copies, and received generally favorable reviews, with praise for its soundtrack, artstyle, and assistive features for newcomers, but criticism for its lengthy story mode, simplicity, and certain design choices. Rhythm Heaven Megamix will be succeeded by Rhythm Heaven Groove for the Nintendo Switch in 2026.
