This is simply not the TETRIS you remember, as the main objective in this installment of the popular puzzle series is to pull the right combination of pieces out of a giant, rotating ball, forcing an explosion that will further open the gap to the ball's core. Each time you reach the center of the ball, you advance to the next level. If you get mixed up or take too much time figuring out how to make the combo, a block gets added to the outer part of the ball, making your job that much harder. Not only that, but three such mistakes will end your game entirely!
