Suit Trainer

Master the art of suit combinations

Play single suit combinations: a shared daily set, survival runs, a practice pool with thousands of combinations, and a solver that shows the best plan for any position you deal. The solver works without signing in; the other modes just need a free account.

A set of combinations each day, the same for everyone - three by default. Your first attempt at each is the one that counts, solved first try or not.
After you play, you can see who else solved it first try and join the chat to discuss the hand.
The archive calendar keeps every day you played, each with its own leaderboard and chat. Days you missed cannot be opened later, and replaying a puzzle never changes your recorded result.

An endurance run: random combinations come one at a time, and each one you solve extends the run. A single miss ends it.
Your longest run counts on the leaderboard, and the page keeps your recent history.

The whole pool of combinations, grouped by how many cards the combination holds. Play any one, or deal a random one you have not solved yet.
After each solve you grade its difficulty from 1 (easiest) to 5 (hardest). Your grades build personal groups - your 1s to 5s, plus everything you missed at least once - so you can go back and repeat the ones you struggled with.

Deal any combination - both hands and a trick target - and step through it card by card. Free and unlimited for everyone, no account needed.
Every card you can play shows its exact success chance, with layout odds and restricted choice built into the number.
Open a card's layouts to explore its full plan: how the line continues after every card the defenders can play, and which layouts it wins or loses. You can select two or more lines to compare them layout by layout.
Positions are shareable - the URL contains the combination, so you can send any position to a friend.

Three all-time boards: The Daily (dailies won first try), Survival (deepest run) and Practice (combinations solved).

The Solver is free and unlimited for everyone, with no account needed.
The other modes need a free account, so your results and streaks follow you across devices.
Practice and Survival each draw from a daily allowance: 3 per day free, 10 per day with Pro, unlimited with Master.
The Daily is unlimited for everyone.

Common questions

The defenders always choose the card that gives them the best chance of winning tricks, given the layouts still consistent with the cards shown - they never give a trick away. Success percentages are computed over every possible lie of the missing cards, weighted by their real odds - vacant places and restricted choice included.

No. The missing cards stay consistent with everything played so far, but they are not dealt in advance: if you do not play the best line, they will lie in the way that stops you from reaching the target, whenever such a layout is still possible.

Taking the stated number of tricks in the suit. If one of your cards lowers your chances, the result panel shows the exact trick, the card that cost, how much it cost, and the card that was better.

A set of combinations each day (three by default), the same for everyone. Your first attempt at each is the one that is recorded - solved first try or not - and afterwards you can see the day's leaderboard and join the chat. Replaying later is free and does not change your result.

No. The archive calendar only opens the days you actually played - a day you missed cannot be recovered.

The Solver is unlimited for everyone. Practice and Survival each have their own daily allowance: 3 per day on a free account, 10 per day with Pro, unlimited with Master. The Daily is unlimited for everyone.

The complete strategy of that line, written out branch by branch: which card it plays next for every card the defenders can play, all the way to the end. Restricted choice and the odds of each layout are already taken into account in every continuation.

A line is a whole plan chosen in advance. It reacts only to the cards that appear - never to cards it cannot see - so it can lose in a layout that would be winnable if you could look at the defenders' hands. The percentages already account for this.

Yes. In the Solver the URL contains the whole combination - copy it and anyone can open the same position, no account needed.
