Suit Combination Calculator
Enter declarer's and dummy's cards in one suit. The analyzer solves every possible lie of the missing cards exactly, in your browser.
The numbers are double-dummy: they assume you guess every layout correctly, so they are a ceiling on any real line of play. The guaranteed figure is the floor against the worst lie. For blind-play practice with real percentages, use the suit combination trainer.

What does the card combination analyzer compute?
For your two holdings in one suit it enumerates every possible lie of the missing cards, solves each lie double-dummy under trainer rules (declarer may lead from either hand each round), and aggregates exact probabilities: expected tricks, chance of at least N tricks, and per-split detail.
Is this the success rate of one line of play?
No. Double-dummy means the declarer is assumed to guess every layout correctly, so the numbers are a ceiling on any real line. The guaranteed figure is the floor: what succeeds against the worst lie.
How many missing cards can it handle?
Up to 8 missing cards (256 layouts), solved exactly in your browser with no server calls.
