Select your cards below and calculate winning probability against a random hand.
This calculator uses Monte Carlo simulation to estimate your odds of winning a Texas Hold'em hand. It deals out 10,000 random scenarios, evaluates all possible 5-card combinations from the 7 available cards (your 2 hole cards + 5 community cards), and compares the best hands to determine win, tie, and loss rates.
The results show your equity against a single random hand. In a real game, your opponent won't have a random hand — they've already decided to play. So use these numbers as a baseline. Premium hands like pocket Aces (~85% vs random) drop to roughly 65-80% against a reasonable opponent range.
Monte Carlo simulation is a mathematical technique that uses random sampling to estimate results. Instead of calculating every possible outcome (which can number in the billions), it randomly deals thousands of complete hands and counts the results. With 10,000 simulations, the accuracy is typically within 1% of the exact answer — more than enough for practical poker decisions.
