If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Create connections between birds of the same type to remove them. For the beginning you only have fifteen seconds to remove a certain number of birds. Move selected bird vertically or horizontally to form groups of three or more birds of the same kind. If you run out of moves, go to your right hint button for help.
This game is played with the mouse only.
