As soon as you sign up for the game Angry Bird Rio, you will change into an angry bird and be prepared to shoot the target in order to release the other birds from their cage.
Using the mouse, you will pick up the birds and throw them into the slingshot. The birds will then be in your line of sight when you drag and release the mouse button. This enables you to shoot the birds in a such that they strike the pedestals, rip them apart, and eliminate all of the birds from the pedestals to beat the opponents in the level.
Before hitting every target, you had to stop because there weren't any more ducks to shoot. You fail. You must continually keep your focus and excitement levels at a high level because each level will be harder than the one before it.
Use mouse.
