Tetris Diamond

Part of G-mode's series of mobile Tetris releases, Tetris Diamond features a unique diamond tetromino. This piece, visibly made out of diamonds, doubles the score for clearing lines when used. It also features the T-spin, a then-recent addition to the Tetris rules which allows a T-piece to be carefully maneuvered into a tight space. There are four different game modes:

• Tetris: The classic game mode.
• Diamond: This game's custom mode featuring the new diamond piece.
• Dia.2min: A two-minute timed game using the Diamond rules.
• Puzzle: Specific predefined puzzles in which players are given specific sets of blocks and must try to clear the entire playfield.
