The price of a call
The explanation below covers the main points. Pot odds compare the chips required to call with the pot you can win after calling. If the displayed pot is P and the call costs C, the simple break-even equity is C divided by P plus C. This basic calculation assumes that calling closes the action and no later bets change the result. Revisit the relevant section if a detail is unclear.
A simple numerical example — details
A useful starting point is the following overview. Suppose the pot contains 100 chips after an opponent's bet and you must call 25. Calling creates a pot of 125, so the simple threshold is 25 divided by 125, or 20 percent. That percentage is a required winning share under the assumptions, not a prediction of your actual hand strength. Use this explanation as a reference during your next visit.
Equity versus pot odds
The explanation below covers the main points. Equity is your expected share of a pot across possible outcomes against the hands your opponents might hold. Pot odds describe the price being offered. Comparing them is useful only when your equity estimate and the assumptions about later action are reasonable. Use this explanation as a reference during your next visit.
Counting clean outs
Here is the context for this part of the site. An out is an unseen card that improves your hand to a result you expect to win. Some apparent outs can also give an opponent a better hand, making them unreliable. Count those possibilities before treating every card of a suit or every straight-completing rank as equally helpful. You can return to this explanation whenever you need a reminder.
One-card draw probabilities
Here is the context for this part of the site. On the flop, with your two cards and three board cards known, 47 cards remain unseen to you. Nine clean outs would represent 9 out of 47 for the next card under a simple unknown-card model. The actual usefulness of those outs still depends on the opponent's hand. Keeping the full context in mind helps avoid misunderstandings.
Two cards to come — details
The explanation below covers the main points. If you will see both remaining cards without further cost, nine clean outs have a probability of at least one hit equal to 1 minus 38/47 times 37/46. That is roughly 35 percent. Paying only for the turn does not automatically buy a free river, so do not use the two-card figure for every flop call. The same principles apply each time you use this part of the site.
Implied odds — details
For this topic, keep the following in mind. Implied odds consider additional chips you might win on later streets when a draw completes. Those extra chips are uncertain because an opponent may fold or stop betting. Large remaining stacks create possibilities, but they do not guarantee a payoff sufficient to justify the current call. A careful reading can help you distinguish the different situations.
Reverse implied odds — details
Here is the context for this part of the site. A hand can improve and still lose a larger pot to a stronger hand. Low flushes, weak top pairs and some straight draws can face this problem. Considering these unfavorable later costs helps avoid counting only the attractive outcomes in a call calculation. The same principles apply each time you use this part of the site.
Side pots and eligible chips — details
The following details clarify how this works. When players are all-in for different amounts, you cannot win every chip shown in the total pot. Your contribution determines which pots you are eligible to contest. Evaluate a decision using the relevant pot and possible additional action, rather than applying the full displayed total without adjustment. Revisit the relevant section if a detail is unclear.
Use the practice hint carefully — details
This section explains what to expect. Practice Mode displays a call-to-pot ratio to make the immediate price visible. It does not inspect hidden opponent cards or provide a guaranteed equity estimate. Compare that ratio with your own assessment of the public board, ranges and future betting before deciding. You can return to this explanation whenever you need a reminder.
