Which Sega crossover game combines Puyo Puyo with the Tetris franchise?

The Sega crossover game combining Puyo Puyo with the Tetris franchise is Puyo Puyo Tetris.

Developed and published by Sega, Puyo Puyo Tetris brings the two puzzle series together in one game. Players can compete in traditional Puyo Puyo or Tetris modes, while crossover modes such as Swap and Fusion mix their distinct rules and playfields.

The original game debuted in Japan in 2014 for Nintendo 3DS, Wii U, PlayStation 3, and PlayStation Vita. PlayStation 4 and Xbox One versions followed later that year, and an English-localized release arrived for PlayStation 4 and Nintendo Switch in 2017. The Switch edition was also released in Japan as a launch title for the system.

It is easy to confuse the title with Puyo Puyo Tetris 2, the 2020 sequel. The other listed options are separate Tetris games and do not represent Sega’s Puyo Puyo crossover. Puyo Puyo Tetris is the original crossover title.
