Pokies Odds: How Probabilities, RTP and Payouts Work

How pokies outcomes and payouts work

Gaming machines use a random number generator to determine outcomes. The game’s design assigns probabilities to possible results, while its rules determine which results qualify for payouts and how much they pay.

When people ask about the odds of winning on pokies, they may mean several different things: the chance of any payout, a payout larger than the stake, a particular prize or a profit over an entire session. Those are separate questions and can have very different answers.

Hit frequency generally describes the chance of receiving a payout on a play. It does not necessarily mean the player has made a profit. For example, a $0.50 gross payout on a $1 spin leaves a net loss of $0.50. A display celebrating a payout does not change that arithmetic.

A session result depends on the stakes and payouts across all plays, not just on whether one spin paid. A player can have several payouts and still finish behind, or have relatively few payouts and finish ahead.

What to check on a paytable

The paytable and help screen explain how a particular game pays. They are a useful starting point before placing a bet, but a list of prize amounts does not necessarily reveal how likely each result is.

The Australia and New Zealand gaming machine standard addresses access to paytables, rules and game features. Requirements and implementation can vary by jurisdiction and machine, so check the information provided for the game you are playing.

Do not assume every game uses paylines or that a maximum bet is always needed for a jackpot or feature. Rules on qualifying bets and the treatment of existing machines vary. The relevant game information should explain the options and any conditions that apply.

• Find the information or help screen and read the game rules.
• Check the denomination and the total amount staked per play.
• Identify selected lines or ways, if the game uses them.
• Look at qualifying combinations and whether listed amounts are gross payouts.
• Read the rules for features, prizes and any selectable options.

Pokies RTP and the payout percentage

Return to player, or RTP, is the expected gross return as a proportion of total wagers over the long run. Gross return means money paid back before subtracting the stakes used to play. It is a theoretical measure, not a promise about what an individual will receive in a session.

For example, a hypothetical game with 90% RTP has an expected gross return of $90 for every $100 in total wagers. A particular player could receive more or less than $90 from $100 of play. Even over many plays, actual results can differ substantially from the theoretical expectation.

The phrase pokies payout percentage needs context. A source may use it to mean theoretical RTP, or it may describe returns actually observed over a particular period. Those figures answer different questions, so check what is being measured and which game version or setting it covers.

RTP also does not tell you the chance of a payout on the next spin. It does not, on its own, reveal hit frequency, the chance of a net-profitable spin or the probability of finishing a session ahead.

Why turnover matters

RTP applies to total wagers, often called turnover, rather than just the money a person initially brings to a venue. Turnover can include the same money more than once when a payout is played again.

For example, someone who starts with $20 could place $30 in total bets if they receive payouts during play and wager some of that money again. The $30 is turnover; it does not mean they brought $30 to the venue or necessarily lost $30.

At a hypothetical 90% RTP, $30 of turnover corresponds to $27 in expected gross returns and a $3 expected net loss under the model. That is an average expectation, not a prediction of the person’s actual result.

House edge and volatility

The pokies house edge is the complement of theoretical RTP when both refer to the same game and model. For the hypothetical 90% RTP above, the calculation is 100% minus 90%, giving a 10% house edge. That corresponds to an expected $10 loss per $100 of turnover, not a fixed loss for every player.

Pokies volatility describes how widely outcomes can vary around the average. Higher-volatility games often involve larger prizes that occur less frequently; lower-volatility games often involve smaller returns more frequently. These are general descriptions, not promises about the next session.

Two games can have similar theoretical RTPs but very different patterns of payouts. Volatility labels are not necessarily standardised, and a higher RTP does not by itself mean that payouts are more frequent or that an individual player will profit.

Can you calculate pokies odds?

You can calculate a probability if you know the relevant outcomes and how likely each is. To calculate expected return, you also need the payout for each outcome and the stake. A pokies odds calculator is only as useful as the information and assumptions entered into it.

The following is an invented, simplified model, not a real machine. Each spin costs $1, and there are ten equally likely outcomes. The amounts listed are gross payouts, before subtracting the $1 stake.

• Six outcomes pay $0 each, producing a $1 net loss.
• Three outcomes pay $0.50 each, producing a $0.50 net loss.
• One outcome pays $7, producing a $6 net profit.

Working through the hypothetical model

Four of the ten outcomes provide some payout: the three $0.50 outcomes and the one $7 outcome. The chance of any payout is therefore 4 divided by 10, or 40%. Only the $7 outcome pays more than the $1 stake, so the chance of a net-profitable spin is 1 divided by 10, or 10%.

To find the expected gross payout, multiply each payout by the number of outcomes that produce it, add the results and divide by ten: (6 × $0 + 3 × $0.50 + 1 × $7) / 10 = $0.85 per spin.

Dividing the $0.85 expected payout by the $1 stake gives a theoretical RTP of 85%. The expected net result is a loss of $0.15 per spin, and the house edge is 15%. None of those figures describes a particular real game.

If spins in this model are independent and have the same probabilities, the chance of at least one net-profitable spin in ten is 1 − 0.9¹⁰, or approximately 65.1%. That is not the chance of finishing ten spins ahead: the stakes and payouts on the other spins also affect the final balance.

A real game’s paytable or RTP alone generally cannot reconstruct its complete probability distribution. A calculator cannot supply a reliable game-specific answer by filling those gaps with guesses.

Are machines due after losses?

A run of losses does not make the next ordinary independent base-game outcome due to pay. Nor does a near miss, a previous player’s losses or an apparent run of wins establish a predictable next result.

Independence means the probability of the next ordinary result is not changed by those previous outcomes. It does not mean every short sequence will look balanced: long runs and clusters can occur by chance.

Some bonus features or sequences have their own rules and may depend on the current game state. Read those rules separately rather than assuming that every displayed step works like an independent base-game spin. A state-dependent feature does not mean the machine must compensate for earlier losses.

Do bet size and game options change the odds?

A bigger bet does not automatically improve the chance of a specified outcome. If a game simply scales the stake and all payouts while leaving the outcome distribution unchanged, doubling the stake doubles the dollar amounts at risk and paid, but not the probability of that outcome.

Changing lines, ways or other options can be different: it may change which results qualify or how the game operates. The effect depends on the rules and configuration, so check the total bet and the applicable options rather than assuming the same outcome probabilities apply.

Increasing the stake also increases the amount exposed on each play. It is not a way to make a negative expected return into a guaranteed profit.

Comparing machines and published information

Different games and configurations can have different rules and theoretical returns. Switching machines, however, does not automatically make a payout or a profitable session more likely.

Start with the machine’s help screen and paytable. Venue staff, the manufacturer or the relevant regulator may be able to provide further information, but the complete probability distribution or exact configuration-specific RTP may not be publicly available.

Be cautious with percentages found elsewhere. A figure for a different version, configuration or jurisdiction is not proof of the setting on the machine in front of you. Before relying on a comparison, check what the source actually describes.

• The game name and version.
• The machine’s applicable configuration, if disclosed.
• The total bet and selected options.
• The payout and feature rules.
• The source and date of any published percentage, and whether it is theoretical or observed.

Australian rules for land-based and online pokies

Land-based gaming machine licensing and technical requirements vary by state and territory. For example, South Australia says a venue needs a gaming-machine licence and an entitlement for each machine. Check the relevant state or territory regulator for current local rules.

Western Australia has a distinct approach: its government says poker machines are prohibited, while certain non-poker electronic gaming machines may be authorised at the casino. It would be misleading to assume ordinary pokies are available in pubs and clubs throughout Australia.

The Australian Communications and Media Authority says online pokies and online casinos are prohibited services when offered to people in Australia. An offshore licence, acceptance of Australian dollars or the fact that a site can be accessed does not establish that the service may lawfully be offered here. The restriction should not be confused with a claim that every person who accesses such a site commits an offence.

Limits and support for gambling harm

Setting spending and time limits, avoiding chasing losses and stopping when gambling is causing harm are practical harm-reduction measures. They do not improve the odds or change a game’s house edge.

If you are concerned about your own gambling or someone else’s, Gambling Helpline is available on 1800 858 858. The service is free and confidential and operates 24 hours a day, seven days a week.

You can also ask your local gambling support service about venue self-exclusion. Check which venues and arrangements it covers rather than assuming an online-wagering exclusion automatically applies to physical venues.

FAQ

Are pokies odds the same as RTP?

No. Odds describe the probability of a defined result, while RTP describes expected gross returns as a proportion of total wagers over the long run. Neither measure predicts what will happen in an individual session.

Does a higher RTP mean I am more likely to win?

Not necessarily. RTP alone does not establish how often a game pays, the chance of a spin returning more than its stake or the chance of finishing a session ahead. It is an expected-return measure, not a guarantee of a better personal result.

Can a pokie be due for a win?

Past losses do not make the next ordinary independent base-game outcome due to pay. A feature may have its own rules or current state, but that is different from a machine being obliged to repay previous losses.

Do bigger bets improve the odds?

Not automatically. If the game only scales the stake and payouts, the probability of a specified outcome stays the same. Changing lines, ways or other game options may change the applicable rules, so check the machine’s information.

Where can I find a game’s odds or RTP?

Start with the help screen, paytable and game rules, then ask venue staff or consult relevant manufacturer or regulator information. The full probabilities or exact RTP for a particular configuration may not be publicly available; a figure for another version is not necessarily applicable.

Can a pokies odds calculator predict the next spin?

No. A calculator can estimate probabilities or expected returns from suitable inputs and assumptions, but it cannot predict the next independent outcome. It also cannot reliably recover hidden outcome probabilities from RTP alone.

Does receiving a payout mean I have won money?

Not always. If the payout is smaller than the stake, the spin is still a net loss. For example, receiving $0.50 back on a $1 spin leaves you $0.50 behind on that play.
