The game is one of the numerous variants of the Tetris idea. The game aim is to aid as many little chicks come into the world as possible. The hen sitting at the roost lays coloured eggs, 3 at a time, which start falling down. Your task is to make them fall so that at least 3 same coloured eggs lie beside every other (horizontally or diagonally). In this case the chicks hatch and the shells vanish.
