Bridge is a strategic and engaging card game that relies on effective bidding, precise play, and intelligent defense. While learning the rules and strategies of bridge is essential, understanding how scoring works is equally important. Whether you are playing for fun, in a club, or in a competitive setting, knowing how to calculate scores can significantly enhance your gameplay. This comprehensive guide will walk you through the fundamentals of scoring in bridge, including contract scoring, bonuses, penalties, and special cases.

1. The Basics of Bridge Scoring
Bridge scoring is based on a combination of factors, including:
- The number of tricks bid and won.
- Whether the contract was made or failed.
- Vulnerability (a condition affecting bonuses and penalties).
- Overtricks and undertricks.
- Special scoring situations such as doubled and redoubled contracts.
Scoring in bridge varies depending on the type of game you are playing. The two most common variations are Rubber Bridge and Duplicate Bridge, each with slightly different scoring systems. Read also more about the basics of bridge card game.
2. Trick Values in Contract Bridge
Each contract in bridge is based on bidding a certain number of tricks above six (the “book”) with a specific suit as trump (or no trump). The trick values depend on the trump suit or whether the contract is played in no-trump:
- No Trump (NT): 40 points for the first trick, 30 points for each additional trick.
- Major Suits (Spades & Hearts): 30 points per trick.
- Minor Suits (Diamonds & Clubs): 20 points per trick.
For example, if a contract is 3 No Trump (3NT) and is fulfilled, the declarer scores:
- 40 points for the first trick beyond the book (trick 7).
- 30 points each for the next two tricks (tricks 8 and 9).
- Total trick score: 100 points.
3. Vulnerability and Its Impact on Scoring
In bridge, vulnerability is a condition that affects bonuses and penalties. Each partnership alternates between being vulnerable and not vulnerable during a match. The impact of vulnerability includes:
- Greater bonuses for making a game or slam contract.
- Harsher penalties for failing to make the contract.
Vulnerability Effects:
| Situation | Not Vulnerable | Vulnerable |
|---|---|---|
| Game Bonus | 300 points | 500 points |
| Small Slam Bonus | 500 points | 750 points |
| Grand Slam Bonus | 1000 points | 1500 points |
| Undertrick Penalty (Undoubled) | 50 per trick | 100 per trick |
Understanding vulnerability is essential when bidding aggressively or deciding whether to double your opponent’s contract.
4. Bonuses for Game and Slam Contracts
In bridge, contracts that achieve a certain level earn special bonuses:
- Game Bonus: A contract that earns 100 or more trick points receives a game bonus.
- Example: 3NT (100 points), 4 Hearts (120 points), or 5 Clubs (100 points) all qualify for a game bonus.
- The game bonus is 300 points (not vulnerable) or 500 points (vulnerable).
- Slam Bonus:
- Small Slam (winning 12 tricks) bonus: 500 points (not vulnerable), 750 points (vulnerable).
- Grand Slam (winning all 13 tricks) bonus: 1000 points (not vulnerable), 1500 points (vulnerable).
If a contract falls short of a game (e.g., 2 Hearts for 60 points), no game bonus is awarded, and only trick points are counted.
5. Overtricks and Undertricks
Overtricks and undertricks refer to additional or missed tricks beyond the contracted amount.
- Overtricks (Extra Tricks Won):
- If a team wins more tricks than bid, they receive extra points for each overtrick.
- In an undoubled contract, overtricks score at normal trick values (30 per major suit, 20 per minor suit, 30 for no trump).
- If the contract was doubled or redoubled, overtricks provide larger bonuses.
- Undertricks (Failed Contracts):
- If declarer fails to make their contract, they receive penalties based on the number of tricks they fall short.
- The penalty increases if doubled or redoubled and is harsher when vulnerable.
Example Penalties:
| Undertrick Count | Not Vulnerable | Vulnerable |
| 1 undertrick | -50 points | -100 points |
| 2 undertricks | -100 points | -200 points |
| 3 undertricks | -150 points | -300 points |
6. Doubled and Redoubled Contracts
During the auction, players can double or redouble contracts to increase both the risk and reward:
- Doubled Contract: If the opposing team doubles your contract, both trick points and penalties increase.
- Successful Doubled Contract: Trick values are doubled, and bonuses apply.
- Failed Doubled Contract: Penalties are significantly higher.
- Redoubled Contract: If a team redoubles, their trick points quadruple, but penalties for failure are even more severe.
Example of Doubled Scoring:
- 2 Hearts (60 trick points) doubled and made = 120 trick points + 50 bonus + game bonus.
- 3 Spades doubled but failing by 2 tricks = -500 penalty if vulnerable.
7. Rubber Bridge vs Duplicate Bridge Scoring
Scoring can vary based on whether you are playing Rubber Bridge or Duplicate Bridge:
- Rubber Bridge: Played over multiple hands, with additional rubber bonuses for winning two games.
- Duplicate Bridge: Each team plays the same hands, and scoring is based on relative performance against other teams.
Key Differences:
- In Rubber Bridge, long-term strategy matters because bonuses accumulate over multiple hands.
- In Duplicate Bridge, each deal is scored separately, making relative performance more important.
8. Summary of Key Scoring Elements
- Trick points: Based on suit and contract.
- Game and slam bonuses: Extra points for winning at higher levels.
- Overtricks and undertricks: Additional or missed tricks affect scoring.
- Doubled and redoubled contracts: Increase potential rewards and penalties.
- Vulnerability: Raises the stakes for both bonuses and penalties.
Conclusion
Mastering bridge scoring is crucial for improving your bidding and play decisions. Whether aiming for game bonuses, managing risk in a vulnerable contract, or using doubling strategically, understanding how scores are calculated gives you a competitive edge. By applying these scoring principles, you can refine your bridge strategy and enjoy the game with greater confidence. So, the next time you sit at the bridge table, keep these scoring rules in mind and maximize your points!
