Simple one finger game play to hit smiley cans with cannon balls.
There are 40 waving green cans spread across 20 levels and your aim is to hit and knock down the cans with balls you fire from the cannon. Move the cannon ball trajectory to where you think it will hit a can and then tap the screen to fire. As the levels get more difficult the cans will be better protected and hidden and much harder to hit and knock down. You will need to bounce the cannon balls off walls, clouds and trees and even blast square and round boulders out of the way just to hit a can. When you knock down a can it will turn red and look miserable. The total number of cans you knock down is displayed in the top left corner of the screen along with the number of cannon balls you have left to fire.
You start with 5 cannon balls and get another 5 each time you successfully complete a level. You complete a level when you knock down both cans on that level.
To complete a level you have to knock down both cans.
