As in all Poker-related games, you have to collect a poker combination, higher than your opponent. Cards sequence is moving between two rows of fangs. When you click on the "Clap" button, these fangs clap and slice cards to 2 parts: upper fangs move down cards to your hand, and lower fangs move up other cards to opponent's hand. After such slicing you have 5 cards. If your combination is higher than opponent's, you go level up, and girls show more and more.
