Sega began streaming a series of tutorial videos for its Western release of the Puyo Puyo Tetris game on Wednesday.
Puyo Puyo Tetris launched in Japan for Nintendo 3DS, Wii U, PlayStation Vita, and PlayStation 3 in February 2014.
The Switch special edition will include keychains: one featuring a green Puyo, and one featuring a purple Tetris block.
Tetriminos and Puyos collide in Puyo Puyo Tetris, with players being able to frantically stack and clear by themselves or compete head-to-head with friends.
