Throw balls at structures to make them collapse but be careful not to exceed the allowed limit! Throw balls at cans and barrels to knock them but try not to throw too hard or slow.Make sure that your accuracy of throwing balls at target increases with levels because difficulty level will increase with time. For the most part one hit is sufficient to knock over the target. There are some levels that are almost impossible, though. I can't remember the level number but all the targets are lying on their sides and moving up and down slowly. You only have one more ball than the number of targets. The objective is straight - knock down cans with the ball. However, the game is easy to play but hard to master and knocking down cans arranged in unique setups like pyramid and more while avoiding obstacles can be really challenging.
