FAQ
Which bridge calculator should I use?
Pick the tool by your question. For the best way to play one suit, use the Suit Combination Calculator. For how the missing cards split, use the Suit Break Calculator. For the score of a contract or an IMP or matchpoint result, use the Score Calculator. For how rare a hand is, use Hand Probability.
Is there a bridge points calculator?
Yes, in two senses. The Score Calculator gives the points a contract scores, made or down, at both vulnerabilities, and converts score differences to IMPs. For high-card points (A=4, K=3, Q=2, J=1), the Odds Reference Tables show how often each HCP count occurs.
How accurate are these bridge odds?
The suit break, hand probability and odds tables are exact: they are computed from combinatorics over the 52-card deck, not from samples. The Suit Combination Calculator gives exact double dummy odds over every possible lie of the missing cards.
