To play the game, use your mouse to click and drag over groups of birds of the same type. You can connect the birds horizontally, vertically, or diagonally, and they don't have to be in a straight line. Try to clear as many birds as possible from the board as quickly as you can to make special powerups appear. These powerups, including the clock, gem, and bomb, can be used like "wild" birds and can be connected to any type of bird. The bomb powerup will clear all of the birds of that type from the board, the clock will give you extra time, and the gem will allow you to connect two different types of birds as if they were the same type. See how high you can get your score!
