You have fifteen seconds available to form groups of three or more birds of the same character. Birds can be moved only vertically and horizontally. Try to eliminate required birds from the right menu. Remove several groups of birds and time will be increased, so have the chance to go the next level with more time available.
You will need to move as quickly, connect angry birds and earn points. If you're stuck and do not know what move to make, you can use the clues button to show you a hint! Every time you use the hint button, the time will flow faster.
