Tetris: The Grand Master 3 Terror-Instinct

Tetris: The Grand Master 3 Terror Instinct introduced several play mechanics to Tetris game play which can be seen today in its sequels and many other Tetris implementations. The basic game play of TGM is similar to that of other Tetris games. The player must move and rotate Tetromino-shaped pieces falling into a well to form horizontal lines, which will then be cleared. During game play, the game automatically gives ranks to the player according to his/her score, starting from 9 all the way up to GM (Grand Master).
