Understand the result, not just the number

PokerOddz estimates how often a selected hand wins, ties, or loses across many possible deals of the unknown cards. The three percentages describe the simulated outcomes under the exact cards and opponent count you entered; they are not a prediction of the next deal.

Win percentage

The share of simulated deals in which your best five-card hand finishes ahead of every active opponent. A win is counted only when you are the sole winner.

Tie percentage

The share of deals in which two or more players have the same winning five-card hand. A tie is different from a full win because the pot would be divided.

Loss percentage

The share of deals in which at least one active opponent makes a stronger five-card hand. Win, tie, and loss should total approximately 100%, allowing for rounding.

Worked example: win probability is not the same as equity

Suppose a study reports 44% wins, 4% two-way ties, and 52% losses. Your win probability is 44%, but your estimated pot equity is 46% because you receive half of each two-way tied outcome: 44 + (4 ÷ 2). This distinction matters whenever ties are possible.

The calculator samples unknown cards without claiming to know an opponent’s private cards or personal playing range. Increasing precision runs more trials and can reduce random variation, but no simulation can guarantee a future result or include every strategic factor.

Frequently asked questions

These answers explain the calculator’s scope, assumptions, limitations, privacy choices, and responsible-use rules.

It estimates win, tie, and loss frequencies for the Texas Hold’em cards and number of active opponents you enter. It deals the remaining unknown cards repeatedly, evaluates each completed hand, and summarizes those simulated outcomes.

No. They are Monte Carlo estimates, so repeated runs can differ slightly. A higher precision setting uses more trials and generally reduces random variation, but the result is never a guarantee about the next card or a future session.

The calculator samples available cards for each active opponent after removing your cards and visible board cards. It does not know a real player’s holdings, infer behavior, or assign a custom hand range, so its output is a neutral study baseline.

Every additional active opponent receives another possible hand, creating more ways for someone to improve beyond yours. Folded opponents are excluded from the simulation, while their unknown cards remain part of the unseen deck.

It is the estimated frequency with which your best five-card hand matches another winning hand. A tie contributes only a share of the pot, which is why win probability and pot equity are not always the same number.

No. PokerOddz is intended for hypothetical examples and retrospective review of completed hands. Do not use external assistance during live play, and always follow the rules of the game, platform, and jurisdiction.

No. The site does not accept deposits or wagers, award money or prizes, run poker games, sell betting tips, or link to poker rooms and gambling operators. It is an educational probability resource.
