Rule highlights
Setup, play, winning, and house rules
Setup
- Four players. You partner the player sitting opposite (North–South, East–West). Empty seats are filled by the computer on this site.
- Deal all 52 cards (no jokers), 13 to each player. The deal passes to the left each hand.
How to play
- Starting with the dealer, each player makes a call: a bid (level and denomination), pass, double or redouble. Three passes after a bid end the auction.
- The player on declarer's left makes the opening lead. Then declarer's partner (dummy) lays their hand face up.
- Declarer chooses and plays dummy's cards. The dummy player just watches for that deal.
- Follow suit if you can; otherwise play any card. The highest trump wins the trick, or if no trump was played, the highest card of the suit led. The winner leads next. Aces are high and twos are low.
Winning
- Take at least the contracted number of tricks (level plus six) to make the contract and score contract points plus bonuses. Fall short and the defenders score for each undertrick.
- The default Chicago format ends after four deals; the side with the higher total wins. Equal totals are a draw.
- With the Rubber setting, the first side to win two games wins the rubber and a bonus of 700 (500 if the other side won a game).
House rules
| Name | Description | Default | Changeable |
|---|---|---|---|
| FormatFormatChicago always ends after four deals, with a fixed pattern of which deals are vulnerable (bigger bonuses and bigger penalties). Rubber is the traditional form: the first side to win two 100-point games takes a bonus, so its length depends on how play goes. Chicago suits a game with a set time. | Chicago ends after four deals and is decided on total points. Rubber is won by the first side to win two games. | Chicago (4 deals) | Yes |
| Part-scores (Chicago)Part-scores (Chicago)A part-score is the score for a contract too low to make game (100). With carry over, it combines with later deals and earns the game bonus once it reaches 100, and a part-score on deal 4 gets 100. Scoring each deal separately closes every deal on its own, with 50 for any part-score. | Whether a contract below game carries over toward game on later deals. | Carry over | Yes |
| HonoursHonoursHonours are the trump A, K, Q, J and 10. With this rule, if one player holds four or more of them, their side gets a bonus whether or not the contract makes (defenders' hands count too). Since it rewards the luck of the deal, turn it off to compare pure skill. | Four of the trump A, K, Q, J, 10 in one hand score 100, all five 150. In no trumps, all four aces in one hand score 150. | On | Yes |
