If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
This game has 18 different levels and your mission is to knock down all the TNT boxes.
When all the TNT boxes fall down, you will get to the next level.
Your time and number of birds are limited so try to think well before throwing any royal birds.
Each level score depends on how many birds are left and how much time remained.
Simply click on the royal bird holded in the pellet-bow then move backwards to aim. Release it only when you consider the direction and angle are the right ones.
Good Luck and Have Fun!
