Tetris Plus (Japanese: ???????, Hepburn: Tetorisu Purasu) is a puzzle video game developed by Natsume and published by Jaleco for arcades exclusively in Japan in 1996, and was ported to the Game Boy, Sega Saturn, and PlayStation later that year. The game would be followed by a sequel, Tetris Plus 2, in 1997. There was supposed to be a port on the Nintendo 64, however that version was never released.
