Press the brick and it will fall try to line it up and make a straight tower. If a brick touches the floor the game stops working and you have to retry. One problem is that there is a glitch that if you tap the middle of the screen and wait than after the first block it makes a perfectly straight Tower. To fix this, after you place a brick each time click off to the side of the tower than continue as normal.
I based this project off of a project in a book called tower builder.
