Eliminate your enemies by shooting them with your caveman slingshot.
Defeat all the rival tribes to progress to the next level. Hit your enemy three times to knock them out.
Click and drag your players around the screen to aim at the enemy. The longer you hold the mouse button down, the further your shot will go. This is indicated by the size of the meter above your player.
Releasing the button will release your shot. Both you and the enemy can survive two hits. On the third hit, they will be out for good!
