Understanding Slots RTP: A Guide to Return to Player

If you’ve ever played online slots or visited a casino, you’ll have seen the term RTP. It sits next to game titles as a percentage, yet it isn’t always obvious what it tells you.

RTP can feel a bit technical at first, but it’s simply a way to understand how a slot is designed to pay out over a very long period. Once you grasp the basics, choosing between games becomes easier.

This guide explains Return to Player in plain English, so you can read slot info with confidence and know what the numbers really mean.

What Does RTP Mean in Online Slots?

RTP stands for Return to Player. In online slots, it appears as a percentage, such as 95% or 96.5%, and shows how much of all money staked on a game is paid back to players over a very long span of play.

If a slot lists an RTP of 96%, that means that, on average across many spins and many players, £96 is paid out for every £100 wagered. It is not a prediction for a single session. Outcomes remain random on every spin, so what you see in one sitting can be above or below the stated figure.

You’ll usually find the RTP inside the game’s information screen or paytable. It is a useful reference point when comparing games or checking how a new release stacks up.

Wondering where that percentage comes from in the first place?

How Is Return to Player Calculated?

RTP is set by the game developer before a slot goes live. They run an enormous number of simulated spins using specialist software, mapping every possible outcome from small line wins to the top prizes.

Across these simulations, the software tracks total stakes and total payouts. The calculation itself is simple: total winnings divided by total stakes, shown as a percentage. For instance, if £950,000 is paid back from £1,000,000 staked, the RTP is 95%.

Because it is based on such a large data set, the figure reflects the game’s design rather than what happens in a handful of rounds. While a slot’s RTP does not change during normal play, some titles are released with multiple RTP settings. Operators choose which version to offer before the game is made available.

With that in mind, why should players pay attention to RTP at all?

Why Does Slots RTP Matter to Players?

RTP gives a clear, long-term view of how a slot is intended to return stakes as prizes. It does not tell you what will happen today, but it does help you compare one game with another in a consistent way.

If you are deciding between two slots, seeing one at 94% and the other at 97% is meaningful. Over time, the higher figure indicates a greater proportion of stakes returned to players, which may appeal if you prefer games with a stronger return profile.

Your choice might also depend on how a game tends to pay within shorter sessions. That is where volatility comes in.

The Difference Between RTP and Volatility

RTP describes the long-term proportion of stakes paid back as prizes. Volatility describes the pattern of those payouts.

• High volatility: wins may be less frequent, but amounts can be larger when they do occur.
• Low volatility: wins tend to be smaller but appear more often.

Two games can share the same RTP, say 96%, yet feel very different. A low volatility 96% slot might produce regular small wins, while a high volatility 96% slot could deliver fewer results but with bigger swings. Checking both the RTP and the stated volatility helps you pick a game that suits how you like to play.

So, with patterns in mind, what counts as a good RTP?

What Is a Good RTP Percentage for Slots?

Many players consider anything from 96% upwards to be a solid benchmark for modern online slots. Titles around 97% are generally viewed as more favourable than those at 92% or 93%, although some branded or classic-style games may sit lower.

Remember, RTP is a long-term average based on extensive testing, not a promise for any single session. You can usually find the number in the game’s info panel, which makes it easy to compare before you start.

RTP can also vary depending on where you play.

Do Online and Land-Based Slots Have Different RTPs?

Online slots often list RTPs in the mid-90s, commonly between 94% and 97%, with some going higher depending on the provider and features. Digital platforms give developers more flexibility to offer different configurations.

Land-based machines, such as those in casinos, pubs or arcades, usually have lower RTPs, sometimes around 85% to 90%. Physical operating costs can influence the settings chosen for those machines. You might also see the same game title offering different RTPs online compared with its venue version. It is worth checking the information shown on the machine or the on-screen help before you begin.

Not sure where to find the exact figure?

How Can You Check a Slot’s RTP?

RTP Display Requirements and Transparency

Finding a slot’s RTP is straightforward on UK-licensed sites. The figure appears in the game’s help section, paytable, or information screen, usually behind an “i” or “?” icon. That page outlines the rules, symbol values and the exact RTP.

For physical machines, the RTP is often printed on a label on the cabinet or displayed on a nearby notice. It can be small, so it may take a quick look to spot it.

UK rules require operators to make this information available and easy to access. If you cannot find it, customer support should provide the details on request.

One final point on setup that is useful to know.

Can RTP Change Over Time?

A slot’s RTP does not change during ordinary play. Once a particular version is configured by the developer and selected by the operator, that percentage stays fixed for that version.

Some games are released with several possible RTP settings, and an operator chooses which variant to offer before the title goes live. If the operator later updates the software or switches to a different version, the displayed figure can change. It is always worth checking the current RTP in the game’s info screen, especially after an update or relaunch.

Under UK rules, any change to a slot’s RTP must be communicated clearly so players can see which version is in use.
