A tower of tin cans, wooden crates, glass blocks, stone cubes and sticks of dynamite stands on a purple carnival platform, and your cannon is loaded with a limited number of balls. Aim, fire, and watch the whole stack wobble, tip and tumble off the stand.

Every level is a new tower: castles of cans, domino lines, layer cakes of crates, glass gates and mixed piles that fall only when you hit the right support. Clear the stand before the balls run out to open the next level.

Along the way you unlock special shots: a heavy ball, a blast that pushes everything away, a triple volley and a piercing shot that goes straight through. Short rounds, real physics and cheerful plastic toys make it an easy pick-up-and-play game for kids and families, on a computer or a phone.
