Bridge scoring for beginners
The score rewards accurate contracts. Start by understanding part-score, game and undertricks; the detailed numbers will become familiar through play.
First compare tricks with the contract
A contract of 3NT promises nine tricks. If declarer wins nine, it is made exactly. Ten tricks means one overtrick. Eight tricks means down one, giving the defenders an undertrick penalty.
Undoubled trick values
| Denomination | Contract points |
|---|---|
| Clubs or diamonds | 20 for each contracted trick above six |
| Hearts or spades | 30 for each contracted trick above six |
| No Trump | 40 for the first contracted trick, then 30 each |
Only the tricks promised in the contract determine whether the contract is a part-score or game. Undoubled contracts worth at least 100 contract points earn the game bonus. This is why 3NT, 4♥, 4♠, 5♣ and 5♦ are the lowest game contracts in their denominations.
Common bonuses and penalties
| Result | Basic undoubled score |
|---|---|
| Made part-score | Contract and overtrick points plus 50 bonus |
| Made game, not vulnerable | Contract and overtrick points plus 300 bonus |
| Made game, vulnerable | Contract and overtrick points plus 500 bonus |
| Small slam: 12 tricks bid and made | Additional 500 not vulnerable or 750 vulnerable |
| Grand slam: 13 tricks bid and made | Additional 1,000 not vulnerable or 1,500 vulnerable |
| Undoubled undertrick | 50 each not vulnerable or 100 each vulnerable |
Double and Redouble increase contract points, bonuses and penalties. Their scoring is more detailed, so it is sensible to learn it after ordinary contracts.
Why bidding the right level matters
What vulnerability does
Vulnerability increases both reward and risk. A vulnerable game or slam earns a larger bonus, while going down costs more. The board states the vulnerability before the auction begins.
Duplicate scoring
In Duplicate bridge, several players play the same deal. Your raw score is compared with the other North–South or East–West results on that board. Matchpoints reward each result you beat and usually half a point for each tie. This means an extra overtrick can matter, but making a sound contract remains the first priority.
Beginner priority: know the number of tricks required, recognise the common game contracts, and concentrate on making the contract before chasing an overtrick.
