About Bridge

Contract Bridge is a classic four-player partnership card game. You and an AI partner bid, then try to make your contract against two AI opponents.

This version uses traditional Rubber Bridge scoring. A game is won by scoring 100 contract points below the line, and the first side to win two games wins the Rubber. Bidding determines the level and denomination of the contract: clubs, diamonds, hearts, spades, or no trump.

Practise Standard American, commonly known as SAYC, with optional bidding hints, hand review, replays, claim tricks, and custom card-display options. Play free in your browser or offline in the Coppercod apps.

Quickfire Rules

Bridge is a four-player partnership game. Each player receives 13 cards. In the auction, players may pass, bid a contract, double, or redouble. A contract states how many tricks above six the declaring partnership must win and whether a suit is trump or the hand is played in no trump.

After the opening lead, the declarer’s partner becomes Dummy and places their cards face up. The declarer plays both hands. Players must follow suit where possible; otherwise, they may play any card. The highest card of the led suit wins each trick unless a trump is played.

In Rubber Bridge, successful contract points are scored below the line. The first side to reach 100 below-the-line points wins a game, and the first side to win two games wins the Rubber. Bonuses and penalties are scored above the line.

Bridge Terms

Bid — Each player in turn can bid a number of tricks and a suit (or No Trump) they believe their partnership can win above 6. ​

Trick — Each player plays a card in turn, and the best card played wins that trick. There are 13 tricks in each hand.

Trump — Trumps are set by the winning bid unless a “No Trump” bid was made, and are elevated higher than all other cards. They can be played when a player cannot otherwise follow suit.

No Trump — A “No Trump” bid has no trump suit.

Undertricks — Penalty points awarded to your opponents if you fail to make your contract

Overtricks — Bonus points awarded to you if you take more tricks than your contract

Rubber — A Rubber is completed when one pair has won two out of three games, which are won by the first team to win 100 contract points in the game. As many hands are played in each game as necessary until a team makes that target.

Double — You may Double an opponents bid during the auction, which applies extra bonuses for winning or extra penalties for losing the contract.

Redouble — If your contract is doubled by your opponents, you may Redouble to apply even more bonuses to the score.

Penalty Double — A type of Double made during the auction when you believe your opponents will not make their bid

Takeout Double — A type of Double made during the auction to tell your partner that you are strong in your opponents unbid suits.

Vulnerable — A team becomes vulnerable in the game if they have won one game in the Rubber. Being vulnerable increases the bonus points awarded and penalty points given away. (see Scoring below)

HCP — High Card Points. Used to measure the relative strength of your hand to use as a guide for bidding. 4 points for every Ace, 3 for every King, 2 for every Queen and 1 for every Jack. A total of 40 HCPs exist in the deck.

RP — Revalued Points. Used to measure the relative strength of your hand in response to your partners bid suits. Extra points can be awarded for shortness in side suits

Side suit — A suit that is not the current trump suit.

Major Suit — Either Spades or Hearts. They are considered major because they are worth more points in trump contracts.

Minor Suit — Either Diamonds or Clubs. They are considered minor because they are worth less points in trump contracts.

Final Contract — The last bid followed by three passes. This is the contract the winning team must make.

Declarer — The player from the winning contract team who first bid the winning suit. They play the hand for their team.

Dummy — The player from the winning contract team who did not first bid the winning suit. Their cards are turned face up after the opening lead and are played by the Declarer.

Below the line — Points awarded for successfully making a contract. These points count towards winning each game.

Grand Slam — Bidding for and winning all 13 tricks in a hand.

Small Slam — Bidding for and winning 12 out of 13 tricks in a hand.

TIPS

How Your Partner Plays

Bidding

Your partner, and all AI players, stick to the Standard American bidding rules. If you are unfamiliar with bridge bidding, or are used to an alternative system, it's worth reading about the basic rules before you get started.

The Stayman Convention and the Jacoby Transfer are used by the AI players when responding to NT opening bids. The AI players also use the Blackwood Convention for determining how many winners the team have for Slam Bidding. It's worth reading about these conventions too if you are unfamiliar with how they work.

The basic rules for the Standard American system are listed below:

  • Hand evaluation is based on the 4-3-2-1 point count system (Ace=4, King=3, Queen=2 and Jack=1) with adjustments for the location of honors and suit distribution.
  • A hand-strength requirement of at least 12-13 points to open 1-of-a-suit.
  • Five-card majors: opening a major suit promises at least a five-card holding in that suit.
  • Weak two bids: Two Diamond, Heart or Spade openers are made with a sound six-card suit in a hand without enough overall strength to open 1 of the suit.
  • Strong two Clubs: All unbalanced hands too strong to open at the one-level are opened with an artificial 2♣ call, as well as balanced hands stronger than 21 HCP.
  • Pre-emptive opening bids: Suit openings above the two level are pre-emptive, promising a long and strong suit.
  • Limit Raises: A jump-raise of the opener's suit by responder, in the absence of opponent interference, is invitational to game.
  • Notrump openers show a balanced hand, with the following common high card point (HCP) ranges:
    • 1NT=15-17 HCP
    • 2NT=20-21 HCP
    • 3NT=25-27 HCP

General Play

  • With the opening lead, your partner will lead a card from a suit you bid during the auction (if any), a suit that was unbid by the opponents, or lead a suit they are strong in.
  • They are watching your response to their leads. If you play a low card (2-5), they assume you want them to stop running the suit, and if you play a high spot card (6-9), they assume you want them to continue.
  • They will watch your lead and try to bring that suit back for you where possible.
  • If they spot that you are void in a suit they will run that suit to give you the opportunity to trump (when there are trumps)
  • In NT contracts, they will attempt to establish winners in suits they are strongest or longest in.

Strategy Tips

  • Start with high-card points, distribution, and any fit with partner: Bridge bidding is about the combined partnership hand.
  • Prefer a five-card major when opening where the bidding system supports it, and show confirmed support early.
  • As declarer, plan before the first trick: count likely winners in no trump and likely losers in suit contracts.
  • As a defender, use the auction and cards already played to infer suits, strength, and likely distribution.
  • Treat doubles carefully: their meaning depends on the auction and may be takeout or penalty.
  • Use the optional bidding hints to understand how Coppercod interprets the current auction.

How To Play

Bridge is a classic four-player partnership game using one standard deck of 52 cards.

The aim of the game is to be the partnership with the highest score at the end of the Rubber.

At the end of each round, the winning bidders score contract points if they met or bettered their contract, or penalty points are awarded to their opponents if they fail. The Rubber is won when the first team wins two out of three games.

Deal

The dealer is initially chosen at random, and then moves clockwise round the table for subsequent rounds.

13 cards are dealt to each player.

Bidding

The bidding starts with the dealer and moves to their left in a clockwise rotation.

Players, in turn, can pass or bid the number of tricks they believe their team can win above 6 in a preferred trump suit or “No Trumps”.

Bids are ranked low to high as follows: Clubs, Diamonds, Hearts, Spades and No Trump. A bid must be higher than the current winning bid. A higher ranking bid of equal numerical value will beat a lower ranking bid. For example, a 3♠ bid will beat a 3♦ bid.

After three consecutive players say “Pass,” the bidding is over and the winning contract is set.

Players may also “Double” an opponent's bid, who may in return “Redouble”. This affects points awarded for the contract.

Play

Whoever is left of the Declarer leads a card to start. Each player must play one card in a clockwise order, following suit where they can.

The winner of each trick is the player who plays the highest card matching the suit of the first player to play, unless a Trump is played, in which case the highest Trump will win the trick.

If you cannot follow suit you may play any other card from your hand.

Scoring

This game uses traditional Rubber Bridge scoring rules.

At the end of each hand, the tricks the winning bidding team collects are totalled and compared to the bid.

Contract points are awarded based on the following table for successful contracts. These points are scored “below the line” and count towards winning a game. See the table below for total points for each trick taken above 6 for each contract type:

Normal Dbl Rdbl
♣♦20pts40pts80pts
♥♠30pts60pts120pts
NT (1st trick)40pts80pts160pts
NT (add'l)30pts60pts120pts

Bonus points can also be won, and count towards your team's total score, but not for a game score above the line.

One-off bonus points

  • Making a doubled or redoubled contract - 50 points
  • A bonus for winning the Rubber. Winning 2 out of 2 games is worth 700 points. Winning 2 out of 3 games is worth 500 points.
