Bridge Bidding Simulator

BridgeDummy helps you simulate bridge bidding decisions by generating many deals consistent with the auction and constraints, then scoring your options with double-dummy analysis.

Auction-based deal generation

Evaluate a bid in context: generate many deals consistent with the auction and your constraints (shape, points, suits).

Objective evaluation

Candidate bids are compared using double-dummy analysis across many generated deals, removing luck from the result.
