Bridge Bidding Practice Online: Every Tool Compared (2026)

Bridge bidding practice online splits into three jobs that look similar but need different tools. First, solo judgment training with objective scoring: you bid a hand and find out whether your bid was right, measured across many deals, not just one lucky layout. Second, partnership practice: you and your regular partner bid the same boards and learn where your system leaks. Third, learning a system: someone explains why a bid is right, beyond whether it scored well.

No single tool covers all three. I tested every major option as of August 2026, and most serious players will combine two or three. This roundup covers what each one does, what it costs, and which of those three jobs it fits. Prices change; check the vendor's pricing page.

I built BridgeDummy to answer a question that kept nagging me after club games: was my bid actually good, or did I just get lucky with the layout?

The bidding puzzles are the core of it. Each puzzle gives you a hand and an auction, then scores every possible bid against every alternative using double-dummy analysis over 1,000+ deals, on a 1-5 star scale, in both matchpoint and IMP scoring. Every option is scored, so you see how close alternatives compare, rather than a plain "right or wrong." An ELO rating per puzzle type and mistake review track where you leak points.

For partnership bidding, Bidding Challenges let you and a friend bid 8 boards asynchronously with EPBot filling the other seats. The creator pays 8 diamonds per table; the partner plays free. Free-practice tables cost nothing. After each board, you see full contract evaluation and what contracts other pairs reached. What Should I Bid is a free calculator: enter any hand and partial auction, and the engine suggests the next bid.

Free tier: 50 diamonds per month, at 1 diamond per puzzle. What Should I Bid costs zero diamonds. Paid plans start at $4.99/month. Web and Android.

Drawback: No structured beginner curriculum. BridgeDummy works best for players who already know the basics and want to measure specific decisions.

Cuebids is the standard for partnership bidding practice. Over 14,000 users. You invite your partner, bid deals whenever convenient, and get instant double-dummy feedback on a 0-3 star scale. Systems: 2/1, SAYC, Acol, Precision, Polish Club, custom conventions, and more.

The free tier is generous: unlimited partner bidding, 48 tickets per month, one deal type, daily and weekly events. Diamond plan: $5.99/month or $59.99/year. Heart plan: $18.90/month or $189/year, covers both partners. Web, iOS, and Android.

Cuebids has more bidding systems and a deeper partnership ecosystem: Leak Finder, deal-type filters, pro comparisons. But its scoring grades the result with 0 to 3 stars, a coarser scale than a 1 to 5 star grade of every alternative. BridgeDummy scores every alternative bid, where Cuebids grades the final contract.

Drawback: Solo practice is limited. If you want to train bidding judgment alone, you need another tool alongside it.

bid72 is a partnership bidding app similar to Cuebids. $3.49/month or $28.99/year, with a 21-day free trial.

bid72 is iOS and Android only. No web version, which limits desktop players. The community is smaller than Cuebids. If you already have a regular partner and prefer mobile, bid72 is a focused, affordable option.

Drawback: No web version and a smaller user base than Cuebids.

Bridgetastic pairs a Bidding Trainer with Brian, an AI coaching chatbot. Brian answers questions about any hand or auction in plain English. The Hand Analyzer breaks down completed deals. The encyclopedia has 1,900+ articles.

Free tier: 10 Brian questions per day and 10 bidding trainer hands per day. Pro: $5/month or $39/year. Web only; iOS is coming, Android is in beta.

I respect what Bridgetastic does differently. Brian gives text explanations of why a bid is right, which is valuable when you are learning a system or want reasoning rather than a number. The tradeoff is that AI text feedback depends on the model's training data and may not always match expert consensus. Bridgetastic is better for learning why than for measuring how well, over many deals.

Drawback: AI text feedback, not objective DD scoring. Web only for now.

Funbridge is a solo play app, not a bidding trainer. You play full deals against Argine, and your result is compared to a field of other players. It has a Bid Decoder for post-hand analysis, but no standalone bidding practice mode. Argine plays Standard American only.

Free: 2 deals per day. Premium: $15.99/month or $174.99/year. Premium+: $24.99/month or $274.99/year. iOS, Android, and web.

Drawback: No isolated bidding practice. Expensive if bidding training is all you want. Only Standard American.

Bridge Base Online is the largest online bridge platform. Bidding practice is not a core feature. You can play robot deals, but there is no bidding quiz or progressive puzzle mode.

BBO Trainer is a separate mobile app (iOS and Android only). Free: 4 deals per day plus the Daily Challenge. Premium: $9.99/month with a 1-month trial. BBO Premium costs $5.99 per month for the first year, then $9.99 per month.

BBO does not score your bidding separately from your cardplay. GIB bidding has been described as "about C-player level" on BridgeWinners. In December 2025 BBO replaced it with GIBBO, a neural-network upgrade that outperformed the old GIB in BBO's own testing.

Drawback: No isolated bidding scoring.

Bridge Winners hosts free bidding polls where experts vote on what they would bid and explain their reasoning. Each poll shows the distribution of votes with discussion threads.

This is the best free source for understanding how strong players think about contested decisions. It is passive: no practice loop, no scoring, no deal generation. Web only, intermediate-to-expert.

Drawback: Passive learning only. You cannot enter your own hand and get scored feedback.

SAYCBridge is a free, open-source web tool. Enter an auction and it tells you what SAYC says to bid next. No random deals, no scoring, no feedback loop.

SAYCBridge covers SAYC only and is not actively maintained. Useful as a quick lookup.

Drawback: SAYC only, no practice mode, limited maintenance.

1. Solo bidding judgment with objective scoring. This is where BridgeDummy leads by the widest margin. The bidding puzzles score every bid against every alternative using double-dummy analysis over 1,000+ deals, in both MP and IMP, with 50 free diamonds a month at 1 per puzzle. You get ELO tracking, mistake review, and the free What Should I Bid calculator. I have not found another tool that scores every alternative bid. Bridgetastic's Bidding Trainer is a reasonable alternative if you prefer AI text feedback over numerical scoring.

2. Partnership bidding with your regular partner. Cuebids is the specialist. Largest community, most systems, custom conventions, deal-type filters, and Leak Finder. BridgeDummy's Bidding Challenges are a strong second option: full contract evaluation, field comparison, and the partner plays free. bid72 is a simpler mobile alternative.

3. Learning a system or getting explanations. Bridgetastic's Brian chatbot explains bids in plain English. Bridge Winners polls show expert reasoning on contested decisions. BridgeDummy's What Should I Bid suggests bids for any hand and auction. SAYCBridge is a free lookup for SAYC only.

Several tools on this list score your bidding with double-dummy analysis. Here is how it works and where it falls short.

After you bid, the engine generates hundreds or thousands of random deals that match the auction, respecting the information each bid conveys. For each deal, it calculates the number of tricks every possible contract would make with perfect play by both sides. Your bid is scored by how well the contract you reached performs across all those deals.

This method is fair because it removes luck. A bid that reaches a good contract on average, over 1,000 deals, will score well regardless of any single unlucky layout. The larger the sample, the more reliable the grade. BridgeDummy uses a minimum of 1,000 deals per scored puzzle. Cuebids also runs 1,000 simulations per board (Cuebids scoring).

The limit is that double dummy assumes perfect cardplay by both declarer and defense. In practice, some contracts that are cold double-dummy get defeated at the table, and some that should fail get made on a defensive error. DD scoring evaluates the contract you reach, not how well you or your opponents would actually play it. I wrote about this tradeoff in detail: Double-Dummy Limitations.

Most improving players need two or three tools from this list. My recommendation: BridgeDummy's bidding puzzles for daily solo training with objective scoring, Cuebids for partnership practice, and Bridge Winners for expert perspective. Start with the free tiers before you pay for anything.
