Bridge Scoring Table

Find the contract in the left column and read across to the vulnerability. Every entry assumes declarer took exactly the tricks bid, undoubled. The figures most players look up are the games. Not vulnerable, 3NT scores 400, 4♥ or 4♠ 420 and 5♣ or 5♦ 400. Vulnerable they become 600, 620 and 600.

Each entry adds two things. The trick points come first, 20 a trick in clubs and diamonds, 30 in hearts and spades, and in notrump 40 for the first trick and 30 after. Then comes a bonus. A contract worth less than 100 in trick points is a part score and gets 50. One worth 100 or more is a game and gets 300 not vulnerable or 500 vulnerable.

Two jumps in the columns follow from that. The first is at game. 3♠ scores 140, but 4♠ scores 420, because the bonus changes from 50 to 300. The second is at slam, where a further 500 or 750 arrives for twelve tricks and 1000 or 1500 for all thirteen. 6♠ not vulnerable is worth 980, more than twice the game below it.

Minor suits are the slow road. 2♣ scores 90 and 3♣ 110, and it takes eleven tricks to reach game. Notrump gets there in nine, since the first trick counts 40.

Overtricks, doubles and redoubles are not on the grid, because each adds a dimension the table would need a page for. Overtricks undoubled score at the trick value of the suit. A doubled contract that makes doubles its trick points and earns 50 for the insult, which can lift a part score into game. For any of those results the scoring calculator gives the exact figure, and contracts that fail are covered by the undertrick penalties.

The scoring guide explains why duplicate gives the bonuses on every board instead of carrying part scores forward as rubber bridge does. If you keep a summary card at the table, the bidding cheat sheet pairs well with this one.

How much is 3NT worth in bridge?

3NT made exactly scores 400 not vulnerable and 600 vulnerable. The tricks are worth 100 (40, 30 and 30), and the game bonus adds 300 or 500.

What is a small slam worth?

A small slam in a major made exactly scores 980 not vulnerable and 1430 vulnerable. That total is 180 in trick points, the game bonus and the slam bonus of 500 or 750.

Why is 5♣ worth the same as 3NT?

Both contracts are worth exactly 100 in trick points, five clubs at 20 each and three notrump tricks at 40, 30 and 30. Each gets the same game bonus, so both score 400 not vulnerable and 600 vulnerable.

What does a grand slam score?

7NT made scores 1520 not vulnerable and 2220 vulnerable. 7♠ or 7♥ scores 1510 and 2210, ten points less because the first trick is worth 30 rather than 40.
