Double Dummy Bridge Solver
Enter a deal, pick a contract, and explore optimal play with double-dummy analysis. For decision evaluation across many possible deals, use BridgeDummy simulations.
Try it here: tap a highlighted card to play it, tap a number in the table to change the contract, or tap the pencil to enter your own deal.
A double dummy solver works out the best possible result on a deal when all 52 cards are known: for any contract it returns the maximum tricks each side can take and the winning play at every turn. It is the benchmark behind BridgeDummy bidding and lead puzzle scores. Real play differs, because real players do not see all four hands.
Enter a deal
Paste a PBN or click cards into each hand to build the exact deal you want to analyze.
Choose contract
Select trump and declarer, and see double-dummy trick counts for each strain and declarer.
Play card-by-card
Click legal cards and see how choices affect double-dummy outcomes at each position.
FAQ
- What is a double-dummy bridge solver?
- A double-dummy solver computes optimal play with all four hands known, returning the maximum tricks available for each side (and often best-play suggestions).
- Does BridgeDummy include a double-dummy solver?
- Yes. BridgeDummy includes a browser-based double-dummy solver tool where you can enter a deal, choose a contract, and play card-by-card with double-dummy guidance.
- Is this bridge solver free to use online?
- Yes. The solver runs in your browser at no cost and needs no account. Enter a deal by clicking cards or pasting PBN, and it shows the double dummy tricks for every contract and declarer, then the best card at each turn as you play.
- How is this different from BridgeDummy simulations?
- A solver analyzes one fixed deal. BridgeDummy simulations can generate many deals consistent with an auction/constraints, solve them, and average outcomes to evaluate bidding or opening-lead decisions.
