Accelerating Birds

• 1). Begin a game by selecting a level. If you choose a level after world 1, level 16, you may have yellow, triangle-shaped birds in your group.
  
  
• 2). Pull the yellow bird in the slingshot back by touching the screen or clicking it with the mouse. Pull back and aim by setting the angle and power (distance from the slingshot). Release to launch the bird into the air. If you don't have the yellow bird in the slingshot, launch the other birds until he is in the slingshot.
  
  
• 3). Tap the screen again while the bird is in midair. The bird will accelerate and crash into the structures with more force than normal. Note that this only works with yellow, triangle-shaped birds.
  
  

Exploding Birds

• 1). Select a level after world 2, level 14 to get exploding birds in your attack group. These are the round, black birds.
  
  
• 2). Launch the black bird from the catapult, targeting the pigs. Aim for a weak spot in their structure.
  
  
• 3). Tap the screen to initiate an explosion, or wait a few seconds. You can do this while the bird is in the air, or after it has landed. When the bird explodes, it damages an area of the screen, and any pigs or tower blocks in the affected area.
