Bridge contract scoring gives members a clear method for reading every completed deal without guessing how each result changes the score. At CRAZYWINGO, this article is written for players who want accurate totals, clearer records, and a stronger understanding of contract results.
Core principles that shape bridge contract scoring
A bridge score begins with the final contract, the declaring side, the trump suit, and the number of tricks actually won. CRAZYWINGO presents this topic as a structured calculation rather than a prediction, so members can follow each value from start to finish. Every deal must first confirm whether the contract succeeded, failed, or produced extra tricks beyond the stated level before any bonus or penalty is entered.
In bridge contract scoring, suit values, doubled status, vulnerability, bonuses, and penalties are applied in a fixed order. Minor suits award fewer trick points than major suits, while no trump gives a higher value for the first scoring trick. This order prevents mixed totals and helps players compare duplicate bridge results with fewer recording errors across repeated scoring checks.
How contract scores and bonuses are calculated
Successful contracts receive basic trick points first, followed by overtrick values and any bonus earned from the contract level. The final amount depends on strain, declaration, vulnerability, and whether opponents doubled or redoubled the bid at the close of bidding.
Reading bridge contract scoring tables
Clubs and diamonds award 20 points for each contracted trick above six, while hearts and spades award 30 points. No trump awards 40 points for the first contracted trick, then 30 points for every additional contracted trick. These values count only tricks named in the contract, not extra tricks won after success during the same deal.
A contract of three hearts therefore carries 90 basic trick points because three contracted tricks are valued at 30 points each. A contract of three no trump carries 100 basic trick points because the first trick earns 40 and the next two earn 30. Players should separate basic values from later bonuses before writing the full deal total on the official score sheet.
Adding partial and game bonuses
A successful contract below 100 basic trick points receives a partscore bonus of 50 points, regardless of vulnerability. Once basic trick points reach at least 100, the result qualifies for a game bonus instead of a partscore bonus. Non-vulnerable game contracts add 300 points, while vulnerable game contracts add 500 points after the declared contract succeeds.
The game threshold uses contracted trick points above six only, so overtricks cannot turn a partscore contract into a game contract. This rule is central to bridge contract scoring because bonus eligibility is decided before extra tricks are added. Members can verify the contract value first, then apply the correct game or partscore award without changing the original bid.
Counting tallying and overtrick values
A small slam means a successful contract at level six, while a grand slam means success at level seven. Small slams add 500 points when non-vulnerable and 750 when vulnerable, on top of game and trick points. Grand slams add 1,000 points when non-vulnerable and 1,500 when vulnerable.

Undoubled overtricks usually follow the normal suit value, giving 20 points in minors and 30 points in majors or no trump. Doubled overtricks rise to 100 points when non-vulnerable and 200 when vulnerable, with redoubled values twice as large. These additions make bridge contract scoring sensitive to both bidding pressure and the final trick count.
How penalties and overall totals are recorded
Failed contracts transfer points to the defending side, with larger penalties applied when the contract is doubled, redoubled, or vulnerable under bridge contract scoring rules. Accurate records require the number of undertricks and the contract status before any penalty amount is entered.
Calculating unmarked contract penalties
An undoubled contract that fails gives defenders 50 points for each undertrick when the declaring side is non-vulnerable. The penalty becomes 100 points for each undertrick when the declaring side is vulnerable, without progressive increases. This simple structure applies equally across suits and no trump contracts at every available bidding level.
For example, a non-vulnerable contract down two gives defenders 100 points, while a vulnerable contract down two gives 200 points. The original trick value is not added because failed contracts do not earn contract points for declarers on the completed score sheet. In bridge contract scoring, success and failure therefore follow completely different calculation paths.
Applying doubled doubled penalties
A doubled non-vulnerable contract down one gives defenders 100 points, while the second and third undertricks add 200 points each. Every further undertrick adds 300 points, creating a steep increase when the contract misses by several tricks. Vulnerable doubled contracts give 200 for the first undertrick and 300 for every later undertrick.
Redoubled penalties are twice the corresponding doubled amounts, so members must confirm the final bidding status before recording anything. A missed redoubled contract can produce a large score even when the number of undertricks appears small. Correct status checks keep bridge contract scoring consistent across tables, separate sessions, and duplicate comparisons between competing pairs.
Combining merging and final entries
Successful doubled contracts receive a 50-point insult bonus, while successful redoubled contracts receive a 100-point insult bonus. Their basic trick points are also doubled or redoubled, which can move a low-level contract above the game threshold. Overtricks then use the special doubled or redoubled values based on vulnerability.
The final entry should show contract points, game or partscore bonus, slam bonus when relevant, overtricks, and insult bonus in separate readable fields. Defending scores should show only the applicable undertrick penalty when the declaration fails before the required number of tricks is reached. Following this order keeps bridge contract scoring readable and reduces mistakes during fast result entry.
