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.
Free and unlimited. Hover a bot call to see what it meant, or replay the hand to try another route.
Bidding Room questions
- Is the Bidding Room free?
- Yes. Unlimited deals with a free account.
- 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 1,000+ simulated deals. The Bidding Room is a full auction, graded on the contract you reach.
