FlopKit
FlopKit is a free Texas Hold'em reference site for players who want the numbers in front of them instead of in their head. Everything lives on one page: the ten hand rankings with exact by-the-river frequencies, the full 169-hand starting grid, the order of betting across all four streets, and the pot odds behind a close call. No account, no email gate, no paywall.
The frequencies come from the combinatorics rather than from simulations. There are C(52,7) = 133,784,560 seven-card sets; a royal flush appears in 4,324 of them, which is 0.0032%, or 1 in 30,940 — the widely quoted 1 in 650,000 is the five-card-draw figure. The starting grid covers all 169 hand types (13 pairs, 78 suited, 78 offsuit, drawn from 1,326 two-card combinations) and groups them into play, conditional and fold tiers as a starting reference for newer players, not a fixed answer for every position, stack depth or table.
Every reference page is also built to print from your browser, where you can save it as a PDF. A4 (210x297 mm) and US Letter (8.5x11 in) use the full one-page layout; pocket size (4x6 in) splits it into two condensed cards. Each prints in colour or black and white, with no watermark, so the sheet works as a one-page handout or desk reference and the pocket cards as a quick reference to carry.
FlopKit does not claim a named professional reviewer. Probabilities are combinatorial frequencies, not solver output or simulation estimates, and every page carries a correction contact for anyone who finds an error.
