The deck consists of 44 cards. There are 8 sets of 5 bird cards, and 4 owl cards. Each of the 8 sets have a letter on them, then each of the birds within the set are numbered 1 through 5. The object of the game is to collect as many sets of 5 with the same letter on them as you can. The game proceeds with players asking for cards from each other and assembling sets. If you have a card but don't want to give it up, you may play an owl card. As soon as you have a set of 5, lay it down in front of you. When all sets have been assembled the game is over.
