Description: You have to stack up all of the shapes in logical order that they don't fall down. In each level, you have a different mission with different shapes. There are many shapes for you to play. You should use your brainy skill to arrange them standing straight. After your shapes had been stacked, you need to make sure that they can stand firmly for at least 10 sec. When you stacked up all of the shapes successfully, you move to the next level. Be a good stacker!!!
