FAQ

How is a bridge contract scored?

Trick score (20 per level in minors, 30 in majors, 40 then 30 in notrump) plus a game, part-score or slam bonus, plus overtricks, or undertrick penalties when the contract fails. Doubling multiplies the trick score and changes overtrick and undertrick values.

How do IMPs work?

The score difference between the two tables of a team match is converted to International Match Points on the official WBF scale, from 0 IMPs (0-10 points) up to 24 IMPs (4000+).

How do I calculate IMPs?

Add your table's score to your teammates' score at the other table, both from your side's view, then find the total on the IMP scale. Example: you make 4♠ vulnerable for +620, and at the other table the opponents go down one in 4♠, so your teammates score +100. The total is 720 points, which is 12 IMPs.

How are matchpoints calculated?

On each board you get one matchpoint for every pair you beat and half for every tie, shown as a percentage of the maximum.

What does a game score in duplicate bridge?

A making game scores the trick points plus a game bonus of 300 not vulnerable or 500 vulnerable. So 3NT scores 400 or 600, 4♥ or 4♠ scores 420 or 620, and 5♣ or 5♦ scores 400 or 600. A part-score adds a bonus of 50, and a slam adds 500 or 750 (small slam) and 1000 or 1500 (grand slam).
