Tetrominout is a combination of Tetris and Breakout. Create lines before the Breakout ball obliterates your setup, or use the ball to ‘fix’ any mistakes you made in your Tetris wall.

Both the ball and the tetrominos increase in speed independently depending on your skill. If you are bad at Tetris, the Tetrominos will fall slower and the ball will move faster and vice versa.
