Or even more fun, trance one player so the idea of cheating never occurs to them; and they never even consider the possibility that someone else might cheat.
You could also add some forfeits. My idea was to play an altered version of hearts, such that it works when the players don't necessarily have a complete deck between them, and it can also be adjusted for different lengths of game. With this one, I'd have one player (me?), or maybe 2 or 3, tranced so that they don't even think cheating is possible, and also they become excited, feeling a wave of "naughty" or embarassing pleasure every time they win a hand with heart(s) in. more hearts = more intense pleasure; if the total value of hearts in a trick is more than 21 (faces & aces count 10), they might even orgasm from it.
Here's the rules I'd use:
1) Each player draws 10 (or 7) cards to start
2) One player leads a random card (from the deck) for the first trick. After that, the last player to win leads.
3) In order to play a heart, you have to pay by removing an item of clothing.
4) You have to follow suit with the first card if you can.
5) The highest card of the right suit wins the trick.
6) If you win a face card, you can draw another card into your hand.
7) If 2 players play the same card, they can both draw a card. If they win, they both get the point for winning the trick, and someone deals a random card to lead the next trick.
8) As everyone has their own deck, players can join or leave mid game.
9) If you run out of cards and still want to play, you can draw a new hand by doing a forfeit chosen by the player to your left.
10) Agree a forfeit before the game, to be performed by anyone who wins the jokers or black lady (Jokers can be played, but can't win a hand)
11) The "winner" could be whoever wins most tricks when everyone's out of cards; but the real fun of the game is in the forfeits and the special trance effect of the hearts; so I deliberately tweaked it so they're not directly linked to the victory condition.
