What RTP means at new online casinos

RTP, return to player, is the share of all money staked on a game that it pays back over a very long run. A 96% RTP slot pays back £96 for every £100 staked on average, so the house keeps £4.

RTP says nothing about a single session. Over a few hundred spins your result can be far above or below it, especially on high-volatility games.

That percentage describes an average across a very large number of plays, not a personal forecast. The game's RTP and its volatility answer different questions: expected return over time and how widely results can swing.

Check the information screen for the exact version loaded. The same slot title can be configured at different RTP levels, so the name alone cannot tell you the setting.

Where to find it

Open the game's information or help screen. UK-licensed casinos must make the RTP available for each game. Many studios release a slot in several settings, often from about 94% to 97%, and the casino chooses one.

The game's information panel is the most useful place to check because it identifies the configuration loaded for that session. Look for a percentage in the paytable, rules, or game help menu; the wording and menu location vary by studio. A casino lobby tile may name the game without showing its return setting, so a search result or promotional description may not settle which version is running.

A published RTP is a theoretical property of a configuration, not a live reading of recent results. Short streaks do not change the displayed percentage. If the figure is absent or unclear, ask the casino which version it offers before you play, and do not infer a value from another casino's copy of the same title.

What a few points are worth

RTPAverage cost per £1,000 staked
97%£30
96%£40
94%£60
92%£80

The table uses the simple house-edge calculation: 100% minus RTP. At 96%, the theoretical edge is 4%, so £1,000 in total stakes corresponds to £40 in expected loss over a sufficiently large sample. The £1,000 is turnover, not a recommended deposit or a single bet.

Turnover counts every wager. If a player stakes £1, loses part of it, then stakes the remaining balance again, the total amount wagered can exceed the original £1. This is why expected cost depends on the number and size of rounds as well as the RTP percentage.

The calculation is an average, not a forecast for an individual. A session may end in profit, break even, or lose more than the modelled amount. Higher turnover increases the expected amount lost at a fixed edge, while a higher RTP lowers that expectation; neither relationship says what the next spin will do.

These figures assume the displayed RTP applies to every stake and that no bonus terms, jackpots, or game-specific rules change the calculation. For a worked comparison of stake size and pace, see our casino game selection guide.

RTP and volatility

Volatility describes how results are spread: low volatility means frequent small wins, high volatility means long dry runs and rare big wins. Two slots with the same RTP can feel completely different.

RTP and volatility answer separate questions. RTP estimates the share of stakes returned over a very long run; volatility describes how unevenly wins may arrive along the way. A higher RTP does not necessarily mean more frequent wins, because the same theoretical return can be distributed across many small payouts or fewer larger ones.

Imagine two games with a 96% RTP. One may produce small returns regularly, while another may hold more of its return in infrequent features. The shared percentage does not tell you which pattern applies; check the game's rules and paytable for its features, hit frequency if published, and prize structure.

A short session is too small to average out those swings. The result can differ sharply from the long-run percentage, particularly when a game concentrates payouts into rare events. Choose a stake that remains affordable through an ordinary losing stretch, and stop when you reach the limit set before play.

RTP and bonuses

The cost of clearing a bonus is bonus × wagering × (1 − RTP). At 10x and 96%, £100 of bonus costs about £40. A higher-RTP slot makes the same bonus cheaper to clear, if it counts in full. Our bonus hub has a worksheet.

This simplified estimate treats every qualifying stake as fully contributed and assumes the RTP remains constant. Actual offers can limit which games count, cap the stake, restrict withdrawal, or set a maximum cashout. A bonus may therefore cost more to clear than the basic equation suggests, and the result is not a promise that the bonus will be converted into withdrawable funds.

Check the contribution percentage before choosing a game for wagering. If a game contributes only part of each stake, you may need more total play to satisfy the requirement. If a bonus excludes a title, its RTP is irrelevant to that offer's qualifying progress.

Read the rules before accepting an offer, including the qualifying period and withdrawal conditions. Our terms and conditions guide explains what to look for in the small print. If the terms do not state how a game contributes, ask the casino rather than assuming full contribution.

Questions

RTP: questions

What does RTP mean?

Return to player (RTP) is a theoretical percentage of total stakes a game returns over a very large number of plays. At 96% RTP, £96 of each £100 staked is the long-run average return and £4 is the theoretical loss. That is a population average across many plays, not a promise that any player receives £96 back.

RTP also describes gross returns, including winnings that are staked again. It is not a cash-back rate or a prediction for the balance you will have when you stop.

Is RTP the same at every casino?

Not always. Some slots are supplied in several RTP configurations, and a casino selects which version to offer. Check the percentage shown in the individual game's information panel instead of assuming the title has one universal rate.

Two versions can share the same name and artwork yet use different theoretical return settings. Confirm the percentage after the game has loaded, because a casino's general game list may not show the configuration.

Should I always pick the highest RTP?

A higher RTP means a lower theoretical loss per pound staked over a very long run. It does not guarantee a win, reduce the randomness of each spin, or show how much you could lose in a short session. Volatility and enjoyment matter too.

Compare like with like: the same game, stake basis, and return setting. Set a spending limit before play, and treat the whole stake as money you can lose.

Does a bonus change a game's RTP?

A bonus does not normally change the game's programmed RTP. Wagering requirements can make you place more total stakes before a withdrawal is available, so the expected cost of clearing an offer depends on the bonus amount, wagering multiple, eligible games, and RTP.

Read the offer's contribution rules and maximum cashout in the casino terms and conditions. The same calculation is only a model when the game contributes fully and the RTP setting is known.

Can RTP predict what happens in one session?

No. RTP is a long-run expectation, while a session is a small sample. A player can finish above or below the theoretical return, and a high-RTP game can still produce a long losing stretch.

Results from a few hundred spins cannot confirm a game's published RTP. Use the percentage to compare theoretical cost, not as a target balance or a reason to keep playing.
