AI HOLD'EM
Play Texas Hold'em Online vs the Computer
Play heads-up No-Limit Texas Hold'em — one-on-one against the computer — directly in your browser, free, with no download and no sign-up. You are dealt two hole cards, the small and big blinds are posted, and the betting goes around before the flop, turn and river. Make the best five-card hand from your two cards and the five community cards, and win the pot at showdown — or take it down earlier by betting your opponent off the hand. Beginner plays loose and passive, Medium plays solid pot-odds poker, and Hard runs a Monte-Carlo equity engine with sharper sizing and smarter bluffs. Use the bet slider to check, call, bet, raise or move all-in, and press Show odds for your live win chance.
How the AI thinks
Poker is the classic hidden-information game — you never see your opponent's cards — so the AI cannot use minimax the way chess or Othello engines do. Instead it estimates its equity by Monte-Carlo simulation: on every decision it deals your two unknown hole cards and the remaining community cards at random many times over, plays each of those complete boards out to a showdown with a fast five-of-seven hand evaluator, and counts how often it would win. That win probability is compared against the pot odds it is being offered — the price to call versus the size of the pot — to decide whether to fold, check, call, bet or raise, and it sizes its bets according to how far ahead it thinks it is. A capped share of bluffs and semi-bluffs keeps it from being readable. The whole engine runs locally in your browser, in a background worker thread so the table stays responsive, and nothing is sent to a server. It is a solid, honest opponent — not a perfect solver, and the cards still fall as they may.
How to play Texas Hold'em — the rules
- The blinds and the deal. The dealer button posts the small blind and the other player the big blind; each player is dealt two private hole cards.
- Betting rounds. There are four: pre-flop, then after the flop (three community cards), the turn (a fourth) and the river (a fifth). When no one has bet you may check or bet; facing a bet you may fold, call or raise.
- Making a hand. Your hand is the best five cards chosen from your two hole cards and the five shared community cards. Standard poker rankings apply, from a high card up to a straight flush.
- Winning the pot. If everyone but one player folds, that player wins without showing. If the last betting round completes, the players show down and the best hand takes the pot; equal hands split it.
- Heads-up order. One-on-one, the button posts the small blind and acts first before the flop, then acts last on the flop, turn and river.
Tips to beat the AI
- Play position. Acting last (on the flop onward you have the button on alternate hands) lets you see what the AI does before you commit chips.
- Mind the pot odds. If it costs you a small bet to win a big pot, a modest hand can be a correct call; against a huge bet, you need a much stronger hand. Press Show odds to check.
- Value bet your big hands. When you are likely ahead, bet — checking strong hands lets the AI see free cards and draw out.
- Don't pay off the river. A big bet on the river usually means strength; folding a bluff-catcher is often right.
FAQ
Is this real-money poker?
No. It is a free single-player game with play-money chips only — nothing to buy, deposit or withdraw, and no cash value of any kind. Your stack is just a score saved in your browser.
How does the AI decide to fold, call or raise?
It estimates its equity by Monte-Carlo — dealing your unknown cards and the rest of the board many ways and counting how often it wins — then weighs that against the pot odds, with a capped share of bluffs. Solid and honest, not a perfect solver.
What is heads-up poker?
Poker played between two players — you and the computer. The button posts the small blind and acts first pre-flop, and first-to-act switches to the other player after the flop.
What if I run out of chips?
You can top your stack back up at any time with the Reset chips button — it is only play money. Your stack otherwise carries over between sessions in your browser.
Is it free? Does it work offline?
Completely free, no download, no sign-up. The engine runs client-side, so once loaded the game keeps working without a connection. More AI games: AI Hearts, AI Euchre, AI Chess or all games.
