Trainer Login

As a trainer you create groups, invite your students and upload your own training material (PBN). Students download the Redoublet app and can play your games straight away. Afterwards they see their score, an explanation (optional) and the DDS score, and they can replay the game if they wish. Watch the videos above for more details. Students also have access to our Analyse module: they can take photos of any bridge game and then receive the DDS score, and they can replay the game against our robot. See also the video on redoublet.com.

It's free for both the trainer and the student. As a trainer you can create unlimited groups and competitions. Students get access to the app, including the analyse and learn modules — these are and will remain free, so your teaching material always stays freely available to your students. Students also receive one month of free access to our Redoublet competition module — competitions open to all Redoublet members. If students want to keep taking part in Redoublet competitions after that month, they pay €5.99/month (cancel anytime).

Students don’t need to sign up themselves — the trainer (you) creates an account for them. If a student already has an account, they are automatically invited to your group.

Yes, you can add your own teaching materials by using the upload PBN feature.

No, there are no limits on the number of groups, students, or competitions.

The app is available for both iOS and Android. A web version is available, but it is still a BETA (test) version.

The learn module is part of the competition module (it is a form of competition). The learn module always remains accessible to students, even after their trial period has expired or if they don't have a pro account.

The robot plays NBB 5-card Major Club Player and NBB 5-card Major Beginner. Click a system to open its system card.

Our robot combines fixed bridge rules with simulations to decide its bids and plays. It uses only the information available to you as a player — there is no peeking at the other hands. It follows standard conventions (see the bidding system above) but will deviate when its simulations point to a better option. As a result, it can play brilliantly one moment and make a beginner's mistake the next. Overall, we'd rate its level as above-average.

Claims — both those made by your opponents (EW) and the verification of your own (NS) claim — are settled by double dummy analysis. It plays out every possible distribution of the remaining cards and determines exactly how many tricks can be made. This means an opponent's claim may rely on the location of cards you cannot see — that is the nature of a double dummy result. To be clear: during play the robot does not peek at all four hands; it plays only on the information available to it.
