Bidding Room

Bid random deals against bots, take on a situation, or bid with a partner: every contract is scored across the layouts that fit the auction

The Bidding Room is a free bridge bidding trainer: you bid a random deal with three bots and reach a contract. It suits every level, from a beginner learning responses to a partnership testing game and slam judgement. Your grade is how your contract scores in IMPs against every other contract your side could have reached, averaged over the layouts that fit the auction.

How the Bidding Room grades a bid

The Bidding Room deals a random hand and three bots bid with you, playing 2/1 Game Force. When the auction ends, BridgeDummy plays your final contract, and every alternative contract, across 20 layouts that fit the bidding, so you see in IMPs how much your judgement gained or lost.

It is free and unlimited. Hover any bot call to see what it meant, and use the same hand again to test a different route.

Bidding Room questions

Is the Bidding Room free?
Yes. Deals in the Bidding Room are free with a BridgeDummy account and there is no daily limit.
How is my contract scored?
Your hand and partner's are fixed; the opponents' hands are re-dealt to match the auction across 20 layouts. Every layout is solved double dummy for your contract and for the alternatives, and the average difference is shown in IMPs.
Can I practice with a human partner?
Yes. Bidding Challenges let you bid the same boards asynchronously with a friend, with the same contract scoring afterwards.
How is this different from bidding puzzles?
Puzzles ask for one call at a decision point and grade it against at least 1,000 simulated deals. The Bidding Room is a full auction with bots, graded on the contract you reach.
