Contracts Made and Set
The scoring on the traveler depends on whether or not the declarer made or didn’t make his/her contract. Both of these results are sub-divided depending on whether the contract was doubled or redoubled.
The explanations below are in the following categories:
1. Contract made
2. Contract made when doubled
3. Contract made when redoubled
4. Contract set
5. Contract set doubled
6. Contract set redoubled
When in Doubt
Remember, if you are using bidding boxes, the correct score can be
found:
1. Contacts Made - on the back of the bidding box card that
corresponds to the final contract
2. Contracts Set - on the back of the X card (double)
- on the back of the XX card (redoubled)
A. Contract Made
When a contract is made, these are the possible scoring points:
1. Contract trick points
2. Overtrick points (in this case, the same as contract points)
3. Bonus points for either
a. A less-than-game contract (called a part score), or
b. A bid and made game contract
4. Bonus points for a slam that’s bid and made, if any

A. Contract Made (continued)
1. Trick points
The scoring points for tricks are:
20 points for each trick in a minor suit contract
30 points for each trick in a major suit contract
40 points for the first notrump contract trick
30 points for each additional trick in notrump contracts
To compute the tricks score, multiply the number of tricks made
(contract and overtricks) times the trick scoring points for the
contract.
2. Bonus points
Next add either:
a. 50 points for a part score, or
b. 300 points for a bid and made non-vulnerable game, or
c. 500 points for a bid and made vulnerable game.
Finally, if a slam was bid and made, add the slam bonus points.
500 points for non-vul small slam
750 points for vulnerable small slam
1000 points for a non-vul grand slam
1500 points for a vulnerable grand slam
NOTE: Vulnerability is not applicable to part score scoring.

A. Contract Made (continued)
Examples:
a. 3 diamonds making 4 vulnerable
4 x 20 = 80 + 50 = 130
(1) (2) (3)
(1) 4 total tricks made (contract and overtricks)
(2) 20 points for each minor suit trick
(3) 50 points for a part score
b. 5 spades making 6 non-vulnerable
6 x 30 = 180 + 300 = 480
(1) (2) (3)
(1) 6 total tricks made (contract and overtricks)
(2) 30 points for each major suit trick
(3) 300 bonus points for bid and made non-vul game
c. 6 notrump making 6 vulnerable
6 x 30 =180 + 10 = 190 + 500 = 690 + 750 = 1440
(1) (2) (2) (3) (4)
(1) 6 total tricks made (contract and overtricks)
(2) 30 points for each notrump trick plus 10 for first
(3) 500 bonus points for bid and made vul game
(4) 750 bonus points for bid and made vul small slam

B. Contract Made Doubled
Here there are 5 parts to the scoring:
1. Contract tricks
2. Overtricks (if any – different from contract trick points)
3. Bonus points for either:
a. A part score not doubled into game, or (50 points)
b. A part score doubled into game, or (300/500 points)
c. A bid and made game (300/500 points)
4. Slam bonus - if slam bid and made (500/750/1000/1500 points)
5. An automatic 50 points for INSULT (50 points)
Only items “1” and “2” require special scoring.
1. The normal contract trick points score is doubled.
2. The overtricks are 100 points each if non-vulnerable
or 200 points each if vulnerable.
Examples:
a. 3 diamonds making 4 non-vulnerable doubled
3 x 20 = 60 x 2 = 120 + 100 = 220 + 300 = 520 + 50 = 570
(1) (2) (3) (4) (5) (6)
(1) 3 contract tricks made
(2) 20 points for each minor suit trick
(3) 2 times for doubled
(4) 100 points for one non-vul overtrick doubled
(5) 300 bonus points for being doubled into game
3 diams doubled = 6 diams = game
(6) 50 points for insult

B. Contract Made Doubled (continued)
Examples:
b. 5 spades making 7 vulnerable doubled
5 x 30 = 150 x 2 = 300 + 400 = 700 + 500 = 1200 + 50 = 1250
(1) (2) (3) (4) (5) (6)
(1) 5 contract tricks made
(2) 30 points for each major suit trick
(3) 2 times for doubled
(4) 400 points for two vulnerable overtricks doubled
(5) 500 bonus points for bid and made vulnerable game
(6) 50 points for insult
c. 6 notrump making 6 vulnerable doubled
6 x 30 =180 + 10 = 190 x 2 = 380 + 500 = 880
(1) (2) (2) (3) (4)
880 + 750 = 1630 + 50 = 1680
(5) (6)
(1) 6 contract tricks made
(2) 30 points for each notrump trick plus 10 for first
(3) 2 times for doubled
(4) 500 bonus points for bid and made vulnerable game
(5) 750 bonus points for bid and made vulnerable small slam
(6) 50 points for insult
C. Contract Made Redoubled
Redouble has the same 5 scoring parts as doubled, except that now
contract tricks are quadrupled (instead of doubled), overtricks are worth
200 each non-vulnerable and 400 each vulnerable and 100 for insult.

C. Contract Made Redoubled (continued)
Example: Let’s use doubled example “b”, but make it redoubled
b. 5 spades making 7 vulnerable redoubled
5 x 30 = 150 x 4 = 600 + 800 = 1400 + 500 = 1900 + 100 = 2000
(1) (2) (3) (4) (5) (6)
(1) 5 contract tricks made
(2) 30 points for each major suit trick
(3) 4 times for redoubled
(4) 800 points for two vulnerable overtricks redoubled
(5) 500 bonus points for bid and made vulnerable game
(6) 100 points for insult
D. Contract Set
For each set trick, the defense gets:
50 points if declarer is non-vulnerable
100 points if declarer is vulnerable
E. Contract Set Doubled
The defense gets more points for each set trick, depending on the
vulnerability.
1st 2nd 3rd 4th 5th
Non-vulnerable - 100 300 500 800 1100 etc.
Vulnerable - 200 500 800 1100 1400 etc.
F. Contract Set Redoubled
The defense gets twice as much as a doubled set. Per the doubled
table above, compute the score as if it were a doubled contract and
then double the result.
