RaseThe Rubber Bridge App
Play Rase
The full game — auction, play, rubber scoring and double-dummy analysis.
Both are free. In the browser there is nothing to install and no sign-up, and it works on a phone, tablet or computer. The iPhone and iPad app adds no ads, no accounts, no tracking, and plays offline.

About Rase
Rase is rubber bridge for iPhone and iPad, and plays in any browser too. You sit South and bid a real auction against three robot opponents, play the hand out, and score it the traditional way — above and below the line, with part-scores carried, honours counted, and proper game and rubber bonuses. Afterwards a double-dummy solver grades your auction bid by bid and your play card by card.
There is no account and no sign-up either way. The iPhone and iPad app needs no internet connection at all — it never makes one. In a browser you need a connection to load the page, but once it has loaded the game and the analysis engine run on your own machine, and nothing you do at the table is sent anywhere.
Common questions
Which bidding systems does Rase support?
American Standard 2/1 and ACOL, each with its own set of convention switches — Stayman, Jacoby transfers, minor-suit transfers, weak or strong two-bids, Blackwood (regular, RKCB 1430 or 3014), Gerber, Landy, Jacoby 2NT, negative and takeout doubles, better minor or short club, and your choice of signalling and discard methods. The bidding chapter explains every one of them. The robots bid and defend to whichever system you have chosen. Set it all under System & Conventions on the home screen.
Does Rase work offline?
The app, completely. Every part of it, the analysis engine included, runs on your device, and it never connects to the internet.
In a browser, not quite. You need a connection to load the page, and it will not open again without one. After it has loaded, though, nothing further is fetched: the deal, the robots and the double-dummy analysis are all computed in your browser, and no card you play leaves your machine.
Where is my data stored? Will I lose it?
Your settings, current rubber, saved hands, and scorepad entries live in the app's own storage on your device and never leave it. They survive closing the app and restarting your phone. Deleting the app deletes them permanently — there is no cloud backup, so if you delete and reinstall, you start fresh.
Can I use Rase to score a game played with real cards?
Yes. Open Live Scorepad from the home screen, tap in each contract and result, and the pad handles the arithmetic — doubles, vulnerability, honours, game and rubber bonuses. There is a rubber timer and a history of past rubbers. If you want the rules behind the arithmetic, see rubber bridge scoring.
Why does the analysis sometimes say a contract was cold when I went down?
The analysis is double-dummy: it works out what was achievable with all four hands visible. That is the fair benchmark for the cards, not a claim that any human should have found the line. Treat it as the ceiling to aim at — how your hand is graded goes through it in full.
Can I replay a hand?
Yes. Completed deals are kept in the Hand Archive. Open any of them to reread the analysis or replay the deal and try a different line. Replays are not scored.
The robots are too slow / too fast
Adjust the pace under System & Conventions.
Is there any gambling in Rase?
No. There is no wagering, no chips, and no simulated betting of any kind. Scores are the standard rubber bridge point totals used in the card game itself.
New to rubber bridge?
The whole tutorial library is free to read on this site — ten chapters covering your first deal, the rules, scoring above and below the line, bidding systems and conventions, card play and technique, what changes if you are coming to rubber from duplicate, and a glossary of the vocabulary.
It is also built into the app: tap Tutorials & Reference on the home screen.
