The moment you see your two cards you get your win and tie chance, recalculated on the flop, turn and river against the opponents still in the hand.
No-limit Texas Hold'em · Practice table
Sit down against computer opponents and play hand after hand. Your odds assistant updates your win chance and the cards you're waiting for as every card hits the felt.
Practice chips only. No real money, no deposits, no withdrawals, no prizes.
PokerPracticeSimulator is a free browser game for practicing no-limit Texas Hold'em against computer opponents with practice chips. While you play, an odds assistant shows your chance of winning and the exact cards that would improve your hand, so you learn the math of every decision as it happens.
It shows four things on every street: your win and tie chance, the cards you're drawing to, a plain-language read of your hand, and how the computer players are acting.
The moment you see your two cards you get your win and tie chance, recalculated on the flop, turn and river against the opponents still in the hand.
Flush draw? Open-ended straight? See exactly which cards complete your hand, grouped by what they make, with your total outs.
No jargon walls. Every hand gets a short, honest read on how strong it is and whether it's usually worth playing.
Computer players make their own decisions — from loose beginners to tricky regulars who bluff and value-bet.
A practice hand works like a real one: you get two cards, then bet on the flop, turn and river until someone wins the pot.
Choose how tough the computer players are and how many sit with you — or hit Random start.
Fold, check, call, bet or raise. Opponents act on their own and the hand plays to a showdown.
Your win chance and outs update after every new community card. Then deal the next hand.
Short answers first. Each answer links to a source where you can check the numbers.
No. Every chip is a practice chip: you can't deposit, withdraw or win prizes, and you never need an account. If you run out of chips you simply rebuy for free and keep playing.
Your win chance comes from a Monte Carlo simulation: the remaining cards are dealt out 12,000 times against the opponents still in the hand, and the assistant counts how often you win or tie. On the river against a single opponent it checks every possible hand exactly instead.

Outs are the unseen cards that would improve your hand to one that is likely to win. A flush draw on the flop has 9 outs and completes by the river about 35% of the time; an open-ended straight draw has 8 outs and gets there about 31.5% of the time.

A pocket pair flops three of a kind or better about 11.8% of the time, roughly 1 flop in 8.5: of the C(50,3) = 19,600 possible flops, 17,296 contain neither of your two remaining cards, and 1 − 17,296/19,600 ≈ 11.8%. Two suited cards flop a made flush only about 0.8% of the time (C(11,3)/C(50,3) = 165/19,600), which is why suited hands are mostly about draws.

Each computer player rates its starting hand with the Chen formula, then estimates its own win chance on later streets and bets, calls, raises or bluffs according to its difficulty level. Easy players call too much, while hard players semi-bluff draws and size bets for value.
It uses standard no-limit Texas Hold'em rules: two hole cards, five community cards, blinds of 10/20, minimum raises equal to the last raise, and side pots when a player is all in. The best five-card hand at showdown wins, with kickers breaking ties.
