Bridge Bidding and Opening Lead Simulator

Generate many deals matching an auction or constraints, solve them with double-dummy analysis, and compare bidding and opening-lead decisions on the results.

Start FreeTry the Double Dummy Solver

Generate Deals

Simulate many bridge deals consistent with an auction and constraints (e.g. shape, HCP ranges, suit lengths).

Double-Dummy Scoring

Solve each generated deal with double-dummy analysis to evaluate contracts, leads, and outcomes.

Objective Feedback

Puzzles give instant feedback of 1 to 5 stars on how close your choice is to best. Custom simulations show the numbers for each option. Both use double-dummy results, which assume that all four hands are known.

FAQ

Is BridgeDummy a bridge bidding simulator?
Yes. BridgeDummy helps you practice bidding decisions on many generated deals consistent with the auction or constraints. Puzzles give 1 to 5 stars from double-dummy analysis, and custom simulations compare your contracts.
Can BridgeDummy simulate opening leads?
Yes. BridgeDummy compares opening leads by generating many deals consistent with the auction, solving each deal with double-dummy analysis, and scoring candidate leads by expected performance.
Is BridgeDummy only a puzzle site?
No. BridgeDummy includes puzzles and competitive modes, plus custom simulations for advanced deal analysis.
How is this different from a double-dummy solver?
A double-dummy solver analyzes one fixed deal. BridgeDummy can also generate many possible deals consistent with an auction or constraints, solve them, and average outcomes to evaluate bidding or opening-lead decisions.
