Tetris The Grand Master Ace (also known as TGM Ace, and abbreviated as TGMA) is Arika's second Tetris game released for a console in December 10, 2005. It is currently the only game in the TGM series to be released for a home console.
The game reuses several elements from Terror-Instinct, a game from the main series which was released the same year. Block graphics are identical, with different block surfaces between SRS and ARS, and the backgrounds share a space theme, though new images appear in Ace. Many musical tracks from Terror-Instinct also appear in Ace, in addition to having new remixes of Korobeiniki, Kalinka, and Katyusha.
