• A poker odds calculator is a tool that poker players use to determine their odds of winning a hand so as to gain an edge over competitors. The most popular calculators used are for Texas Holdem, Omaha, and 7-Card Stud. For a long time these calculators were only available to Windows users but the good news is that they are now Mac compatible.

Texas Hold'em Cheat SheetOdds Based on Outs after the Flop. If after the flop, you have: Two outs: Your odds are 11 to 1 (about 8.5 percent) A common scenario would be when you have a pair and you are hoping your pair becomes a three-of-a-kind (a set). The odds calculator can be used to simulate heads-up Texas Hold'em situations to find each hand's chance of winning before the flop, on the flop, and on the turn. The values displayed in the bottom right-hand box display the hands' chance of winning, which can be useful in determining whether to call varying sizes of bets and raises.

How the poker calculator works

The Grosvenor Casinos Poker Calculator works by using what’s known as a “Monte Carlo” algorithm. This algorithm estimates the percentage of making a hand in Texas Hold’em by simulating what would or could happen had the hand been played out multiple times. The calculator runs all the possible outcomes of the hand from the point at which the player is on the board until it hits a limit of 12,500 simulations.

Why 12,500?

To ensure a perfectly accurate percentage each time, one would need to run hundreds of thousands of simulations, which would cause the calculator to run much slower – especially where there are no board cards. Instead, we have chosen to impose a limit of 12,500 possible outcomes, which means the calculator is within 1.5% accuracy of the displayed percentages. For calculations that have less than 12,500 outcomes (when the hand progresses further) the calculation is more accurate. To ensure the tool calculates hand percentages as quickly as possible, the calculations run on a separate server – as opposed to the individual’s computer.
