If my mum can recognise a game of Tetris by its ear-worm-for-the-ages Type A music, it's probably not a series that needs much introduction. Puyo Puyo, on the other hand, might be. Even now, 26 years after its initial release, Puyo Puyo has largely been ignored outside of Japan despite being bloody brilliant.
Puyo Puyo Tetris
Publisher: Deep Silver/Sega
UPDATE 06/04/2017 9.22pm: False alarm, everybody. As it turns out, these restrictions only apply to the Japanese versions of the game, not the English language release.
Wondering what to play on your Nintendo Switch after polishing off Zelda? Another game release date has been locked down.
Sega's Puyo Puyo Tetris launches for Switch (and PlayStation 4) on 28th April here in the UK (or 25th April in North America).
It has lots of different modes but the main thing is yes, you can play the basic original Tetris without any of this other gubbins.
