Trick scores
Overtricks score the same per-trick value. Undertricks cost 50 each when not vulnerable and 100 each when vulnerable (more if doubled).
| Denomination | Per trick bid and made |
|---|---|
| ♣ or ♦ | 20 |
| ♥ or ♠ | 30 |
| No trumps | 40 for the first trick, 30 for each after |
Bonuses
So 3NT making exactly, not vulnerable, scores 100 + 300 = 400; 4♠ vulnerable making scores 120 + 500 = 620. Vulnerability rotates with the board number and is printed on the board.
| Result | Not vulnerable | Vulnerable |
|---|---|---|
| Part-score (under 100 trick points) | 50 | 50 |
| Game (100+ trick points) | 300 | 500 |
| Small slam (12 tricks) | +500 | +750 |
| Grand slam (13 tricks) | +1000 | +1500 |
Duplicate: the same deal for everyone
In a club game or championship, the cards are kept in numbered boards and every pair plays the same deals as the other pairs sitting in the same direction. Your score is compared only with the others who held the same cards — luck of the deal is removed and skill decides.
Matchpoints vs IMPs
- Matchpoints (pairs events): on each board you get 1 point for every pair you beat and ½ for every tie. Each board matters equally; an overtrick can be worth as much as making a slam.
- IMPs (teams and some pairs events): the difference between your score and the other table’s is converted on the International Match Point scale (for example 420 vs 170 = +6 IMPs). Big swings matter; small ones do not.
- Victory points (VPs): in team matches the IMP margin is converted to VPs out of 20 to rank the teams in a Swiss or round-robin.
Movements, boards and the director
The tournament director runs the movement (which pairs meet and which boards they play), rules on irregularities under the Laws of Duplicate Bridge, and publishes the results. Scores are entered at the table on Bridgemate devices and appear live on the results site.
Masterpoints are awarded on your finishing position — see Masterpoint Categories for how BFI’s plan works.
