4 honest poker & casino math tools

Our approach: no hype. House-edge math is house-edge math, and pretending otherwise hurts players. These four calculators are designed to make the math obvious so you can decide what's worth your time and money.

Gambling involves risk. If you're chasing losses or gambling more than you can afford, please seek help at begambleaware.org or your local equivalent.

Hold'em Equity Calculator

Fast Monte-Carlo equity vs. a specific hand or a range (e.g. 22+, ATs+, KQs). Unlike heavy clients that require download, this runs entirely in the browser. The unique bit: we also output a "call or fold" suggestion by comparing equity to the pot odds you set.

Omaha Hand Strength

Pot-Limit Omaha is the most misunderstood poker variant. The "nut advantage" flag tells you whether your draws go to the absolute best hand (top of the straights/flushes) or second-best — which often decides the entire hand. We compute raw equity vs. up to 4 ranges and overlay the nut-advantage note.

Blackjack Basic-Strategy Trainer

Pick your hand and the dealer's up-card; the tool returns the basic-strategy decision plus its expected value vs. a stand. Hit/Stand/Double/Split — and a confirmation flag if you're about to deviate from the book. The book reduces the house edge to roughly 0.5% under standard rules.

Baccarat EV Calculator

Baccarat is one of the few casino games where the math is published: banker bet ≈ 1.06% house edge, player ≈ 1.24%, tie ≈ 14.4% (with 8-deck shoe). Use the calculator to see your expected loss for any session length, with a streak tracker that explicitly shows why streaks don't change EV.

The poker page that says the quiet part out loud

Equity vs. ranges — be careful with very wide ranges

A range like "any two" makes equity meaningless — you'll get 50% vs. most hands. The tool warns when the range is so wide that "call or fold" is not actionable.

Blackjack assumes standard rules

S17, DAS allowed, 3:2 blackjack. Some tables have 6:5 BJ or restrict doubles — house edge goes up. Verify before you sit.

Baccarat: yes, banker really is the best bet

Even after the 5% commission, banker has the lowest house edge. Tie is a sucker bet. The math hasn't changed since the 1980s.
