Arrange blocks falling from the top of the screen into rows so that you can clear the bin. Move the shapes into different directions and rotate them by 90 degrees. When a horizontal line without gaps is formed, it clears, and any blocks above that line shift down. Game Center support to play with your friends (requires iOS 6 and later). Offer a challenge to your friends from within the Game Center to beat your score and track their progress as they struggle to catch up.
