Slot RTP Database Every Slot's Real RTP, by Casino

Every slot here carries two RTP figures

The first is what the studio published. The second is what a casino actually runs. On most games those match. On some they don't, and the gap is the single most useful thing on this page.

Studios release games in several RTP configurations and let each operator license whichever they prefer. That means the advertised figure is a ceiling, not a promise — the build in front of you depends entirely on where you're playing. Starburst is the clearest example on this site: NetEnt's specification is 96.09%, but the best build we've found deployed at a UK casino is 94.09%. Two full percentage points, invisible from the reels.

So when you're scanning the grid, the number worth reading is the deployed one. The spec tells you what the game could pay. The deployed figure tells you what it will.

Filter by volatility before you filter by RTP

The instinct is to sort by highest RTP and start at the top. It's the wrong order, and it's the mistake that empties bankrolls.

RTP sets the long-run cost of playing. Volatility decides how that cost arrives — steadily, or in long droughts punctuated by rare bursts. Two games can share a 96% return and behave nothing alike, and for anyone playing to a fixed budget the behaviour matters more than the percentage.

Our own session modelling makes the size of that difference concrete. Take £100, stake £1 a spin, play 500 spins on a 96% slot. On a low-volatility game you'd lose the lot roughly 7% of the time. On a high-volatility one, 53% — more often than not, you're out before the session ends. The expected return is identical in both cases. Only the variance changes, and variance is what actually empties a balance.

Pick the volatility band that suits your budget first. Then take the best deployed RTP available inside it. That's the order that works.

What the filters do

The Provider filter narrows to a single studio, which is useful because studios have house styles — some ship consistently high RTP, others hold back builds for operators to choose from. Volatility splits the database into low, medium and high. Mechanic covers Megaways, bonus buy, wild features, jackpots and penny slots. New shows recent releases.

The RTP control sorts rather than filters — highest or lowest first — and the Sort control handles alphabetical and release order. Filters stack, so you can narrow to high-volatility Megaways games from one provider and then sort what's left by deployed RTP.

Every category page on this site is the same database pre-filtered a different way, so the numbers agree wherever you enter. Browsing to the Megaways page and filtering this grid for Megaways gets you to the same place.

Where the figures come from

RTP is disclosed in each game's own information panel — studios are required to publish it, and UK-licensed operators are required to display the build they're running. That panel is the authoritative source, and it's what our figures are read from. Each entry carries the date it was last confirmed.

That date matters more than people assume. Operators switch builds, so an RTP figure without a date attached is close to worthless. Ours are checked regularly, but a snapshot is still a snapshot: before you play, open the game's info panel and confirm the number yourself. It takes ten seconds and it's the only source that can't be out of date.

Our main coverage is operators licensed by the UK Gambling Commission, where paytable disclosure is enforceable. Outside that jurisdiction it isn’t enforceable in the same way, so we cover crypto and offshore sites separately and flag where a figure can’t be verified to the same standard.

From a number to a decision

Knowing a slot runs at 96.71% rather than 94.51% is only useful if you know what the difference buys you. That gap is £2.20 per £100 staked — about £11 over a 500-spin session at £1 a spin.

If you'd rather see that worked out for your own stakes, the RTP calculator does it directly. The bankroll simulator runs a full session and graphs the balance, which is the fastest way to understand what a volatility band actually feels like. And the comparison tool puts up to four slots side by side, spec against deployed, if you're deciding between shortlisted games.
