Duplicate raw score
The calculator applies contract scoring to one board and reports the declaring side’s signed score with a component breakdown. It is not an IMP, matchpoint, percentage or tournament result calculator.
Rubber is different
Rubber scoring carries a different session structure. Do not use this single-board output as a rubber score sheet. ACBL’s learning material treats the formats separately.
Check the inputs
The final contract, declaring side’s vulnerability, doubling state and actual tricks all matter. A scoring tool cannot infer them from a partial auction.
