1 diamond per board

How it works

A bidding trainer. You and three bots bid a random deal, and your contract is compared in IMPs to every contract your side could have reached.

20 layouts per auction, 5 bidding systems, 1 diamond per random deal

How the Bidding Room grades a bid

You bid a random deal with three bots. When the auction ends, your contract and every alternative are solved double dummy on 20 layouts that fit the bidding, so you see in IMPs what your judgement gained or lost.

Each random deal costs 1 diamond. Hover a bot call to see what it meant, or replay the hand to try another route.

Bid alone against bots. Your contract is scored 1 to 5 stars against double dummy.

Or drill a situation: one auction start with hands you pick.

Bidding Room questions

What does the Bidding Room cost?
Each deal costs 1 diamond, random or built from your own situation. Every account gets free diamonds each month.
How is my contract scored?
Your hand and partner's stay fixed. The opponents' hands are re-dealt 20 times to fit the auction, and your contract and the alternatives are solved double dummy. The average difference is shown in IMPs.
Can I practice with a human partner?
Yes. Bidding Challenges let you bid the same boards with a friend in your own time, scored the same way.
How is this different from bidding puzzles?
Puzzles ask for one call and grade it on hundreds to thousands of simulated deals. The Bidding Room is a full auction, graded on the contract you reach.
