Launch the app and select your difficulty level (Easy, Medium, or Hard). You'll be dealt 13 cards. Start by passing three cards to another player (direction varies each round: left, right, across, or none). The player with the Two of Clubs leads the first trick. Follow suit if possible, or play any card if you can't. Avoid taking tricks with hearts or the Queen of Spades unless you're aiming to Shoot the Moon.
