About Seven2Offsuit

Free poker math tools: a daily fold-or-call decision, an exact odds calculator, range vs range equity, a home-game clock and guides to pot odds, outs and equity. No account, no real-money play.

Hand-against-hand equity is exact: every remaining board is dealt and scored. Range against range is simulated over 200,000 deals, and the margin is shown. Daily Challenge answers compare your equity against a stated villain range with the pot odds, and every assumption is shown after you answer.
