Ten tricks, a kitty and a joker
Ten cards each from a 43-card pack, an auction that runs from six tricks to ten, and three cards in the kitty for whoever wins it. Bid what you think you can make, take the kitty and throw three back, name your trumps, and bring it home — miss it and you lose what you bid.
Above the ace of trumps sit the Joker and both bowers, which is the part everyone learns the hard way. Play four in partnerships, or two-handed where each of you plays a dummy as a second seat. First side to 500 wins, and falling to −500 goes out the back door.
