- RTP (return to player) is a long-term theoretical average, not a prediction for your session.
- Volatility describes how wins are spread – frequent and small, or rare and large.
- The same slot can run at different RTPs at different casinos, so check the game's help screen.
Choose volatility to suit your budget, then RTP to break ties. A high RTP slot that burns your budget in ten minutes is not good value for you.
What is RTP in slots?
RTP, or return to player, is the percentage of all money staked on a slot that it is designed to pay back to players over millions of spins. A slot with a 96% RTP will, in theory, return £96 for every £100 staked – across all players, over a very long time.
In any single session your results can be far above or below that figure. RTP describes the maths of the game, not what will happen in your next hour of play.
RTP and house edge
House edge is simply 100% minus RTP. A 96% RTP slot has a 4% house edge; an 88.12% RTP jackpot slot such as Mega Moolah has an 11.88% house edge.
Why RTP can differ between casinos
Many developers release the same slot with several RTP settings, and each casino chooses which version to offer. That is why we show each developer's published default RTP and recommend checking the figure in the game's help or information screen before you play.
How to find a slot's RTP
- Open the slot at your casino.
- Tap the information, help or paytable icon (often an "i" or "?").
- Look for "Return to player" or "Theoretical RTP" in the game rules.

What is slot volatility?
Volatility (sometimes called variance) describes how a slot distributes its wins. Two slots with the same RTP can feel completely different to play.
| Volatility | How it feels | Example | Suits |
|---|---|---|---|
| Low | Frequent, smaller wins | Starburst | Longer sessions, smaller budgets |
| Medium | A balance of both | Gonzo's Quest | Most players |
| High | Rarer, bigger wins | Book of Dead | Players comfortable with long dry spells |
RTP, volatility and hit frequency
Hit frequency is how often a spin produces any win at all. Low volatility slots tend to have a higher hit frequency; high volatility slots may go many spins without a win before paying a bigger amount.
Using RTP and volatility to choose a slot
- For longer sessions on a smaller budget, try low volatility slots with an RTP of 96% or more.
- For a chance at bigger wins, high volatility slots may suit – but set a firm budget.
- For jackpot slots, accept a lower base RTP in exchange for the jackpot chance.
