Block Stack

game.aboutGame

Block Stacking is a fun stacking and reaction game where you have to stop moving bricks and build your tower as high as possible. Just wait until the next block is geared to the rest of the building and tap the screen to stack it up. You will have to start from the very beginning if you'll click at the wrong moment and let a block fall.
