Bridge Bidding and Opening Lead Simulator
Generate many deals matching an auction or constraints, solve them with double-dummy analysis, and get objective feedback on bidding and opening-lead decisions.
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
Compare candidate actions and get instant, objective 5-star feedback on how close your choice is to best.

FAQ
- Is BridgeDummy a bridge bidding simulator?
- Yes. BridgeDummy helps you practice bidding decisions on many generated deals consistent with the auction/constraints, scored with objective double-dummy analysis and 5-star feedback.
- 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.
