Estimate your Texas Hold'em starting-hand win probability against 1-8 opponents, using a 2,000-trial Monte Carlo simulation with a full 5-card hand evaluator.

Monte Carlo estimate — deals 2,000 random showdowns against uniformly random opponent hands and community cards. Results vary slightly (typically well under 1 percentage point) between runs.
This calculator estimates your Texas Hold'em starting-hand win probability using Monte Carlo simulation: it deals 2,000 complete random hands — your 2 hole cards plus a shuffled deck of the remaining 50 cards distributed as 2 hole cards per opponent and 5 shared community cards — and evaluates the best possible 5-card poker hand each player can make from their 7 available cards on every single deal. Counting how often your hand ends up strictly best (a win) or tied for best (a tie) across all 2,000 trials gives an estimate of your true win probability.
$$P(\text{win}) \approx \frac{\text{Wins}}{\text{Trials}}$$
Wins: the number of the 2,000 simulated deals where your hand was strictly the best hand at showdown.
Trials: the total number of simulated deals — 2,000 for this calculator.
This is an estimate, not an exact answer — the true combinatorial probability would require enumerating every possible deal exactly rather than sampling a random subset of them. With 2,000 trials, the estimate is typically accurate to within roughly 1 percentage point, and running the calculation again will give a slightly different number each time as a new random sample is drawn.
Pocket Aces (A-A) is the single strongest starting hand in Texas Hold'em. Against exactly one random opponent, it wins roughly 85% of hands, ties a small fraction, and loses the rest — mainly to hands that pair up favorably or complete a straight or flush against it. Add more opponents and that win rate drops steadily, since each additional random hand is one more chance for someone to catch a hand that beats even a strong pair — with 8 opponents, even pocket Aces wins well under half the time, simply because there are so many more hands in play that could improve past it.
With 7 cards available (2 hole cards plus 5 community cards), there are 21 different ways to choose the best 5 of them. This calculator evaluates all 21 combinations for every player on every trial and keeps whichever 5-card hand ranks highest, following the standard poker hand hierarchy from High Card up through Straight Flush: High Card, Pair, Two Pair, Three of a Kind, Straight, Flush, Full House, Four of a Kind, and Straight Flush. Ties within the same hand type are broken by comparing the relevant card ranks in order — for example, two Full Houses are compared by their three-of-a-kind rank first, then their pair rank.
Assuming a strong starting hand's win rate stays the same regardless of how many opponents are at the table is a common mistake — win probability drops substantially as more players are dealt in, since more hands means more chances for someone to catch a big improvement. Confusing "win probability against random hands" with "win probability against how real opponents actually play" is another — real players fold weak starting hands far more often than a uniformly random deal would, which meaningfully changes practical odds at an actual table, something this calculator doesn't model. Expecting the exact same percentage on every run is a misunderstanding of what Monte Carlo simulation is — small run-to-run variation is expected and doesn't indicate an error.
Hole Cards — the 2 private cards dealt to each player at the start of a Texas Hold'em hand, not shared with anyone else.
Community Cards — the 5 shared cards dealt face-up in the middle of the table (the flop, turn, and river), available to every player in building their best hand.
Equity — a player's mathematical share of the pot based on their probability of winning the hand at showdown, which is what a win-probability calculation like this one estimates.
Monte Carlo Simulation — estimating a probability by running many random trials and counting outcomes, rather than computing the exact answer analytically — useful when the exact calculation would be too complex to enumerate directly.
This calculator uses Monte Carlo simulation — it deals out 2,000 random hands and counts how often your starting hand wins — rather than computing the exact combinatorial probability. Because each run deals a fresh random sample, the result varies by a small amount (typically well under 1 percentage point) from run to run, converging closer to the true probability as more trials are simulated.
Pocket Aces (A-A) against one random opponent's hand wins roughly 85% of the time heads-up, with a small tie percentage. This is the strongest possible starting hand in Texas Hold'em, and its win rate drops as more opponents are added, since there are more hands that could improve past it.
No. This calculator assumes every opponent plays a uniformly random hand all the way to showdown — it measures your hand's raw equity against random cards, not against how real opponents would actually play. Real opponents fold weak hands and play strong ones, which changes the practical odds at an actual table.
