The game is based on the principle of luck, and you need to place cards on the screen and hope that you'll be able to form a hand that totals 31 in cards of one suit or get a higher score. There is no strategy, no logic behind this game. 

This is the classic version of the card game. Your goal is to beat the opponent. The idea is that you choose a card from your hand and it will be replaced with the one in your pocket. You can choose how many cards to place on the screen and how many cards to choose. You can also make the opponent choose a card instead of choosing a card from your hand.
