What Are the Rules of Bridge? A Complete Beginner's Guide
The rules of bridge are not complicated. The strategy takes years to develop, and the bidding system takes real time to learn, but the mechanics of how the game is actually played are clear and logical. Anyone can follow them after one careful reading.
Bridge rules in plain English: Bridge is a four-player card game played in two partnerships, with each player holding exactly 13 cards from a standard 52-card deck. Every hand begins with a bidding auction that determines the contract: a commitment by one partnership to win a minimum number of tricks. The player who first names the trump suit for the winning side becomes the declarer, and their partner lays all their cards face-up on the table as the dummy. Players must follow suit on every trick; failing to do so when holding a card in the led suit is a revoke and carries a penalty. Bridge rules are governed worldwide by the Laws of Contract Bridge, maintained jointly by the World Bridge Federation and the American Contract Bridge League.

James Harrington has introduced bridge to hundreds of beginners over the years, and the same worry comes up almost every time: “I’ve heard the bridge rules are complicated.” His answer is always the same. The rules of bridge are not complicated. The strategy takes years to develop, and the bidding system takes real time to learn, but the mechanics of how the game is actually played are clear and logical. Anyone can follow them after one careful reading.
This guide explains the bridge rules from the beginning. By the time you reach the end, you will know exactly how a hand is played, what each player is responsible for, and what to do in every situation that comes up at the table. If you would like a broader introduction to the game before reading this, the how to play bridge guide is a good place to start.
What Do You Need to Play Bridge, and How Are the Cards Dealt?
Bridge, formally known as contract bridge, is a four-player game. Players sit at a table with their partner directly across from them and their two opponents on either side. The standard convention is to name the four seats North, South, East, and West. North and South play as one partnership; East and West are the other.
You need a standard 52-card deck with no jokers. One player deals all 52 cards, one at a time in clockwise order, face-down, until each player holds exactly 13. Players then pick up their cards and look at them privately. This is one of the central features of contract bridge: you never show your hand to your partner, and your partner never shows theirs to you. You communicate entirely through the bidding.
Card ranking within a suit
Ace (highest), King, Queen, Jack, Ten, Nine … down to Two (lowest).
Suit ranking for bidding
Clubs (lowest), Diamonds, Hearts, Spades, No Trump (highest). This order takes about five minutes to learn and never changes.
Many players also count their hand using High Card Points before bidding. An Ace is worth 4 points, a King is worth 3, a Queen is worth 2, and a Jack is worth 1. A typical opening bid promises at least 13 High Card Points. You will see HCP mentioned throughout any bridge book, so it pays to know the values from the start.
If you would like a clear picture of where each player sits and how the positions are named, the bridge positions guide is worth reading alongside this one. It explains not just the seating arrangement but also how each seat carries different responsibilities during the auction and the play, which connects directly to what you will read in the sections below.
How Does the Bidding Auction Work in Bridge?
Once the cards are dealt, the hand begins with an auction. Starting with the dealer and moving clockwise around the table, each player makes a call in turn. A call can be one of four things: a bid, a pass, a double, or a redouble.
The four types of call
Each bid must be higher than the previous one. You can go higher by naming a larger number, or by naming a higher-ranking strain at the same number. Two Hearts outbids Two Diamonds. Two Spades outbids Two Hearts.
The auction ends when three consecutive passes follow any bid. The final bid becomes the contract. The player from the winning side who first named the trump suit (or no trump) in that denomination becomes the declarer. Their partner becomes the dummy.
If all four players pass without a single bid, the hand is thrown in, the cards are reshuffled, and a new hand is dealt. This is unusual but entirely within the rules.
What Is the Dummy in Bridge, and What Are the Rules for the Dummy’s Role?
The dummy is the declarer’s partner. After the contract is set, the dummy’s role changes entirely.
Once the auction ends, the player sitting to the left of the declarer makes the opening lead: they choose a card and place it face-down on the table. As soon as it is turned face-up, the dummy lays all 13 of their cards on the table face-up, arranged in four columns by suit. If there is a trump suit, it is placed to dummy’s right by convention. From this point on, the dummy takes no active part in the hand.
The declarer now plays both hands: their own cards and dummy’s. For every trick, the declarer decides which card to play from dummy as well as which card to play from their own hand. The dummy sits quietly. They do not comment on the play, suggest a card, or indicate a preference in any way.
This arrangement is one of the stranger things about bridge when you first encounter it. One player is effectively silent for most of the hand, their cards on the table for everyone to see, while their partner makes all the decisions. It is an unusual rule and one that shapes the entire character of the game.
How Do You Play a Trick in Bridge, and Which Card Wins?
A trick is the fundamental unit of bridge. Thirteen tricks are played in every hand, and the number of tricks won by each side determines whether the contract succeeded or failed.
Each trick contains exactly four cards, one from each player. The player who has the right to lead places their card face-up on the table. The other three players then each play one card in clockwise order. Once all four cards are played, the trick is complete.
Which card wins?
If no trump card has been played, the highest card in the suit that was led wins the trick. If one or more trumps were played, the highest trump wins, regardless of what else is in the trick.
What happens next?
The winner of the trick gathers the four cards face-down and leads the next trick. This continues until all 13 tricks have been played.
One thing that surprises many new players: the first six tricks taken by the declaring side score nothing. They are simply expected. Only the tricks beyond six count toward fulfilling the contract. Those expected six are sometimes called “the book.”

What Does “Follow Suit” Mean in Bridge, and What Happens If You Cannot?
Following suit is one of the most important rules in bridge, and one of the most common sources of confusion for new players.
When a card is led, every other player must play a card of the same suit if they have one. If clubs are led, you must play a club. If spades are led, you must play a spade. You cannot choose to play a different suit simply because it would benefit you. The rule is absolute.
If you have no cards remaining in the suit that was led, you are free to play any card in your hand. You may play a trump, which wins the trick unless a higher trump is played later. Or you may discard a card from another suit, which will not win the trick but may serve a purpose as the hand develops.
For a broader explanation of bridge vocabulary, the bridge terminology guide explains the language of the game in plain terms.
What Is Trump in Bridge, and How Does the Trump Suit Work?
The trump suit is the suit designated as the most powerful suit for the duration of a hand. It is determined by the final contract: whatever suit was named in the winning bid becomes trumps.
A trump card beats any card of any other suit. If spades are trump and someone plays the Two of Spades on a trick where diamonds were led, that Two of Spades wins the trick outright, beating even the Ace of Diamonds. The only way to beat a trump is with a higher trump.
The four possible trump suits
Clubs, Diamonds, Hearts, and Spades. There is also the option of playing in no trump, which means no suit has special power. In a no trump contract, every trick is won simply by the highest card in the suit that was led.
When can you play a trump?
You can only play a trump card when you have no cards left in the suit that was led. You cannot play a trump card purely by choice when you still hold cards in the led suit. The follow suit rule takes priority.
Understanding how trump works is one of the things that makes bridge feel quite different from simpler card games. A declarer in a trump contract tries to use small trump cards to capture high cards in other suits. A good defender watches carefully to preserve their trump holdings for the right moment. It is one of the richest areas of strategy in the game, and it starts with understanding this single rule.
What Is a Revoke in Bridge, and What Is the Penalty?
A revoke occurs when a player fails to follow suit even though they held a card in the led suit. It is a breach of the rules. At club level, most revokes are honest mistakes caused by missing a card hiding among 13, and they are treated as such.
If caught in time
If you realise you have revoked before the next card is led from either hand, the error can be corrected. Take back the card you played by mistake and replace it with a legal card. The incorrectly played card becomes a penalty card and may face restrictions later in the hand. If your partner played after you but before the revoke was noticed, they must take their card back too.
If discovered too late
If the revoke is discovered only after a subsequent trick has been completed, it stands. At the end of the hand, a penalty is applied:
Contract was made
Two tricks transferred from the revoking side to the non-offending side.
Contract was not made
One trick transferred to the non-offending side instead.
The total penalty can never exceed the number of tricks the revoking side won after the revoke occurred.
At a bridge club, if there is any disagreement about a revoke ruling, the director of the session should be called. This is a perfectly normal part of club play and causes no embarrassment. The American Contract Bridge League publishes the complete Laws of Contract Bridge, and any club director will have a copy to hand.
What Does a Complete Bridge Hand Look Like from Start to Finish?
Reading the rules is useful. Seeing them applied to a real hand makes everything fall into place. This is the kind of hand James Harrington uses in his early lessons with new players: clean, compact, and showing every core rule in action. Here it is, played through from first card to final score.
The deal
North deals. After the cards are distributed, North holds:
The auction
North opens Two No Trump, showing a balanced hand of 20 to 21 High Card Points. South has enough to raise directly to Three No Trump. East and West pass throughout. The final contract is Three No Trump, played by North. Three No Trump requires nine tricks with no trump suit.
The contract is Three No Trump. North is the declarer. Nine tricks required, no trump suit.
The opening lead
West leads the Five of Hearts, face-down. North turns it face-up. South (the dummy) lays all 13 cards on the table in four columns by suit.
The play
North can now see both hands. Counting winners: five spade tricks, two heart tricks (Ace and King in North’s hand), and three diamond tricks in dummy. That is ten winners against a target of nine. The contract is comfortable.
Trick-by-trick play
Nine tricks for North–South. Contract made, with one overtrick. East and West take the remaining four tricks, but the contract was home after trick nine and those four tricks cost North–South nothing.
The score
Three No Trump scores 40 points for the first trick above six, then 30 points for each of the next two = 100 trick points. Add a game bonus of 300 (not vulnerable). Total: 400 points to North–South for the hand.
If North had taken only eight tricks instead, East–West would have scored an undertrick penalty of 50 points. The difference between making and going down is 450 points. That is why every single trick matters.

What Are the Most Common Bridge Rule Mistakes Beginners Make?
The rules themselves are clear. Applying them in the middle of a real hand, while also thinking about bidding and strategy, is where small errors creep in. These are the ones James Harrington sees most often from players in their first months of the game.
- Revoking accidentally. A player glances at their hand, sees no clubs nearby, and plays a different suit. Two tricks later, a club appears. The simple cure is to sort your cards by suit at the start of every hand and keep them sorted throughout. One extra minute of organisation at the beginning saves a great deal of awkwardness later.
- Playing out of turn. The order of play in bridge is not optional, and the laws treat it as an irregularity rather than a disaster. If a defender plays or leads a card out of turn, the declarer has a choice: accept the card as legally played, or require it to be withdrawn. If they require it back, that card is likely designated a penalty card, which must be played at the first legal opportunity. If the declarer leads from the wrong hand by mistake, the defenders may require the lead to come from the correct hand instead. At club level, call the director whenever this happens. The ruling will be applied calmly and without drama.
- Looking at dummy before the opening lead. The opening lead must be played before dummy’s cards are visible. The defender on declarer’s left places their card face-down, then face-up, and only then does dummy go down. The sequence exists specifically to prevent the lead being influenced by a view of dummy.
- Treating a bid casually. Every bid is a genuine commitment. A bid of Four Hearts means your side expects to win ten tricks with hearts as trumps. The bridge bidding hub explains what different bids mean and what your hand needs to justify them.
If you are wondering whether bridge is genuinely difficult to pick up, the is bridge hard to learn guide gives an honest answer.
Does It Matter Whether You Are Playing Rubber Bridge or Duplicate Bridge?
The rules above apply to contract bridge in all its forms. There are two versions you will encounter at clubs.
In rubber bridge, the same partnership plays together across several hands, building scores until one side wins two games. Vulnerability changes as the rubber progresses, which affects the size of bonuses and penalties.
In duplicate bridge, which is used in most club sessions and all tournaments, the same dealt cards are played at multiple tables. The scoring uses a different system, using matchpoints or IMPs rather than rubber bridge bonuses. But the rules for dealing, bidding, playing tricks, following suit, and revoking are identical in both forms.
If you would like to understand how duplicate works in practice, the duplicate bridge explained guide covers everything.

Where Do You Go from Here?
The rules are the foundation that everything in bridge is built on. Once they feel settled, the game opens up in all directions.
The natural next step is the bidding. When your partner opens One Spade, what are they telling you? How do you respond? The opening bids guide explains what the first bid of a hand means and what it promises. The bridge bidding cheat sheet is a useful reference to keep alongside you while you are finding your feet.
Once the bidding begins to feel familiar, the scoring is worth understanding properly. Knowing why some contracts earn larger rewards than others makes the bidding feel purposeful from the start. The bridge scoring guide walks through every number on the score sheet.
If you are preparing to play at a club for the first time, the bridge etiquette guide covers the conventions that nobody always explains to newcomers. Reading it before your first session can make the whole experience more comfortable.
The Learn Bridge hub sets out all the topics in a sensible order if you would like a map of what to explore next. If you are still wondering how long it takes before bridge starts to feel enjoyable and natural, the how long to learn bridge guide gives a realistic answer.
Bridge has been played by millions of people around the world for well over a century. The rules you have just read are the same ones used in every club game, every national championship, and every friendly home rubber. They do not change from one table to the next. More importantly, they are genuinely manageable. Every experienced player at your local club once sat where you are sitting now, reading these same rules for the first time.
Key Takeaways
- Bridge is a four-player card game played in two partnerships of two. Each player holds exactly 13 cards, and every hand plays exactly 13 tricks.
- The game begins with a bidding auction. Each bid names a level (one to seven) and a strain (a suit or no trump), committing the bidder’s side to winning that many tricks above six.
- The player who first names the trump suit for the winning partnership becomes the declarer. Their partner becomes the dummy, laying all their cards face-up after the opening lead.
- Players must follow suit on every trick. Playing a different suit when you hold a card in the led suit is a revoke and carries a penalty of one or two tricks transferred to the non-offending side.
- A trick is won by the highest trump played in it. If no trump was played, the highest card in the led suit wins.
- The trump suit, named in the winning bid, beats all other suits. You may only play trump when you have no cards in the suit that was led.
- Revoking, playing out of turn, and looking at dummy before the opening lead are the most common rule mistakes for new players, and all are easy to avoid with a little preparation.
- Bridge rules are standardised worldwide under the Laws of Contract Bridge, maintained jointly by the World Bridge Federation and the American Contract Bridge League.

What Happens When a Player Makes a Bidding or Play Error?
In a club duplicate game with a director, errors are handled systematically. The director is called, explains the ruling, and the game continues. The most common errors and their resolutions: an insufficient bid (a bid lower than the previous one) must be made sufficient by bidding the same denomination at the correct level, or the player must pass; a revoke discovered before the hand ends results in the defending side receiving penalty tricks; a lead out of turn allows the player who was supposed to lead to either accept the lead or send it back.
In casual home play without a director, errors are handled by mutual agreement. The standard approach is to correct the error, return to the point where it happened, and continue from there. If the error cannot be undone (a revoke discovered after the hand ends), the penalty is typically one trick awarded to the non-offending side, but in friendly play this may be waived.
The principle behind all the rules: bridge should be a game where the only information available to either side is the cards, the bids as defined by the agreed system, and the plays made. Anything that gives one side unauthorized information is prohibited. For beginners learning the rules, understanding this principle helps make sense of why specific rules exist even when they seem technical.
Frequently Asked Questions
Each player receives 13 cards, dealt one at a time from a standard 52-card deck. With four players at the table, all 52 cards are distributed with none left over. Because each player holds 13 cards, there are always exactly 13 tricks played in every hand of bridge.
The dummy is the declarer’s partner. After the opening lead is played face-up, the dummy lays all 13 of their cards on the table arranged by suit, and then plays no further active part. The declarer plays cards from both their own hand and dummy’s for the rest of the hand. Dummy may not comment on strategy or suggest which card to choose at any point.
If you hold no cards in the suit that was led, you are free to play any card from your hand. You may play a trump card, which wins the trick unless a higher trump appears, or discard from another suit, which will not win the trick. You cannot choose to avoid following suit if you do hold a card in the led suit.
A revoke happens when a player fails to follow suit while holding a card in the led suit. At club level it is almost always an honest mistake and is handled calmly. If caught before the next trick, the error is corrected with a penalty card. If it stands, the penalty is two tricks transferred to the non-offending side when the contract is made, or one trick when it is not. The session director can always be called if the ruling is unclear.
The opening lead is made by the defender sitting to the left of the declarer, and it is the only card played in the entire hand before either defender can see dummy. The opening leader must rely entirely on the information from the auction. A well-chosen lead can immediately put the contract under pressure; a poor one can hand the declarer an easy ride. It is one of the most closely studied decisions in the game.
