AI built for Bridge
DOM.ia, our artificial intelligence, is built on the Google Gemini API. But technology alone is not enough: we have fed and trained the model with exclusive technical documentation created by Ramón Gómez, professional Bridge player and multiple Spanish champion.
This combination of computational power and real expert knowledge is what allows DOM.ia to offer precise analysis, contextualized suggestions and explanations that a player of any level can understand and apply.
Real-time analysis
During the game, DOM.ia analyzes the bidding state and offers you suggestions for the best available bid, analysis of each declaration and explanations of card play errors. All in real time, without interrupting your game.
Analyze the bidding
Here is the analysis of each bid:
What should I bid?
My recommendation is 5
With your support and additional values, 5♣ is a competitive bid to make it harder for East-West to find their contract and to show the great club fit.
Replay analysis
Once the game is over, DOM.ia breaks down each bid and each play. It shows you your successes, points out errors and suggests alternatives with clear explanations. The perfect tool to learn from every hand.
Play Analysis with Dom.IA
This analysis identifies two critical errors in the play: West lost a potential trick at trick 3 by not developing their long diamond suit. At trick 5, North (dummy) made an error by discarding a spade, weakening their strongest suit instead of discarding a less valuable diamond card, costing the declaring side a trick at that point in the game.
ErrorTrick 3: West played 7
West, as defender, played 7 instead of a diamond. This choice was suboptimal because it didn't actively seek to establish West's diamond suit to generate tricks, losing a potential trick for the defense.
Better play: 7
Playing 7 would have been superior because it would initiate the development of West's diamond suit, which contained the J, potentially creating a trick for the defense and increasing their total trick count by one.
ErrorTrick 5: North played 4
North (dummy) discarded 4 , a card from their strongest suit (spades, where they hold AK). This discard was an error because it unnecessarily weakened the potential for tricks in spades for the declarer.
Better play: 8
Discarding 8 would have been better because it would preserve the strong spade suit structure (AK642), maximizing the declarer's sure tricks in that suit and maintaining the total trick potential for the declaring side.
The engines that play
Bridgedom's bots are not a single model. The auction is handled by a specialised external engine with the conventions implemented at professional level. Card play is decided by our own engine, which simulates thousands of possible layouts of the hidden cards (Monte Carlo) and evaluates each one with our Double Dummy solver, written in C++ and compiled to WebAssembly so it runs on your own device.
The difficulty levels are built on top of that engine. Each level, from beginner to expert, is a profile with its own parameters —how many layouts it simulates, how long it thinks, how often it makes a deliberate mistake and how bad that mistake can be— so a beginner gets an opponent their size and an expert gets one that doesn't forgive.
Built-in assistant
DOM.ia is built in as an assistant exactly where it can actually help: in the auction and in the post-game analysis. From there you ask for what you need —what a call means, what the best available bid is, why a play was a mistake— and it answers in plain language, without leaving the game.
