Book of Ra Deluxe
A land-based cabinet classic ported online. Settings vary by operator, so check the figure on the info screen rather than trusting a review table.
Straight answer
The only reliable return figure is the one inside the game's own information screen on the site you are playing. Open the paytable through the menu inside the game, the RTP is stated there, and it reflects the exact configuration running on that account.
British slots typically sit between 94% and 97%. A one-point difference is worth £1 per £100 wagered on average, which is real but far smaller than the effect of volatility on any single session.
What the number actually means
Short version: it is a long-run average, not a promise about tonight. Return to player is the proportion of everything wagered on a game that it pays back across its entire modelled lifetime. Billions of spins, not your session. A 96% slot returns £96 per £100 wagered on average, over a sample far larger than any individual will ever produce.
Two consequences follow, and both are routinely misunderstood.
It says nothing about your evening. Over a few hundred spins, actual returns scatter enormously around the average. Players regularly finish well ahead on a 94% game and lose quickly on a 97% one. That is not the figure being wrong; it is the figure describing something other than a single session.
It is a rate, not a budget. The house edge applies to turnover, not to your deposit. Wager £500 on a 96% slot and the expected cost is £20, regardless of whether that £500 of turnover came from a £50 deposit recycled ten times or a single £500 stake.
Checking the real figure, in three taps
- Open the game. Demo mode works and costs nothing.
- Open the menu, usually the burger icon or a small "i" in a corner of the game frame.
- Find the paytable or game rules and read to the end. The RTP is normally stated in the final section, often alongside the maximum win multiplier.
If the figure there differs from a table you read elsewhere, the in-game number is the one that applies to you. Where a game offers optional modes, a feature buy, or a selectable volatility setting, each mode frequently has its own return figure, and the paytable lists them separately.
Why the tables disagree: studios commonly release the same title
at several return settings, sometimes spanning four or five percentage points. A review
published against one configuration is simply describing a different build from the one you have
open.
Titles worth checking first
These are games with a reputation for competitive returns, chosen to span different mechanics. Verify each one in the paytable before deciding. The reputation is not the setting.
Starburst
Low volatility, both-ways pays and no bonus round. The reason it is still in every free-spins promotion is that its variance is predictable.
3 Pyramids of Gold
Three separate pyramid meters fill as coins land, splitting the top prizes into smaller, more frequent hits than a single jackpot ladder.
Mighty Fish Blue Marlin
One of the few titles that lets you pick the volatility level before spinning, which changes hit frequency without changing the return figure.
Rain and Ruin
Bleak art, brutal maths. Worth a demo run first so you can see how long the base game can go without paying anything meaningful.
Olympus Rivals
Two reel sets compete for the same bonus trigger. It plays faster than it looks because both sets can pay in the same spin.
Notice what the list is not: it is not ordered by RTP, because publishing a ranked table of figures that vary by configuration would be exactly the mistake this page is about.
Where the genuinely better returns are
Chasing an extra half point between two slots is a rounding error compared with changing category. The differences between game types are much larger than the differences within them.
| Game | Typical return | Conditions |
|---|---|---|
| Blackjack | Over 99% | Playing a correct basic strategy, favourable table rules |
| Video poker | 97%–99.5% | Depends heavily on the paytable and correct play |
| Baccarat (banker) | About 98.9% | Commission applies on winning banker bets |
| European roulette | About 97.3% | Single zero only; double-zero wheels are much worse |
| Mainstream slots | 94%–97% | Varies by configuration |
| Progressive jackpot slots | Lower base return | Part of every stake funds the pot |
Blackjack is the outlier, and the condition attached to it is not optional: over 99% assumes a correct basic strategy on every hand. Played by instinct, the edge collapses. The strategy is a published table, freely available, and it takes an evening to learn.
There is a catch that keeps this honest. The categories with the best returns are exactly the ones excluded from bonus wagering, for the same reason: the house edge is too thin to fund a promotion. You can have the better return or the bonus, not both at once. See the wagering page.
Check it yourself, in the game
Demo mode, menu, paytable. Thirty seconds, and it is the only figure that applies to your account.
What RTP cannot do for you
It does not make a game due
A slot below its stated return over your last hundred spins is not owed a correction. Each spin is independent, and the certified random number generator has no record of what came before. "Due" is a feeling, not a mechanism.
It does not describe a session
Two slots at identical returns can produce completely different evenings if their volatility differs. If you want a session that lasts, volatility is the number to look at, not return. The slots page covers the trade.
It does not make gambling profitable
A 97% slot loses 3% of everything wagered on average. Better is better, and better is still negative. Anyone presenting a high-return title as an income strategy is describing something that does not exist.
It does not tell you what a session costs
The figure applies to turnover, and turnover is not the same as what you deposit. A £50 deposit played through five times generates £250 of turnover, at which point a 96% game has an expected cost of £10, not £2. People consistently underestimate this because they think in deposits and the maths works in wagers.
It cannot be changed mid-session
We cannot alter a certified game's return figure while you play, and no game behaves differently because your balance is high. Certification exists specifically to make that impossible, and it is tested by independent laboratories.
Used correctly, the figure is a tiebreaker: given two games you equally enjoy, pick the one that returns more. Used as a strategy, it will not carry the weight put on it.
Questions UK players actually ask
What is a good RTP for a slot?
Anything at 96% or above is competitive for a British slot. The band across the market runs roughly 94% to 97%, and a single percentage point is worth about £1 per £100 wagered.
How do I check a slot's RTP at Casumo?
Open the game, open its menu, and read the paytable or game rules to the end. The figure stated there reflects the configuration actually running on your account.
Why do different sites quote different RTPs for the same slot?
Because studios release several configurations of the same title and operators choose which to run. Both figures can be accurate for different builds, only the in-game one applies to you.
Which games have the highest return at Casumo?
Blackjack played with a correct basic strategy, at over 99%, followed by video poker and baccarat. All of them are usually excluded from bonus wagering for that reason.
Do jackpot slots have lower RTP?
Their base return is lower because a slice of every stake funds the progressive pot. The total return including the jackpot can be competitive, but almost none of it reaches an average player.
Can a casino change a game's RTP?
Not mid-session, and not on a certified game running a fixed configuration. Independent test laboratories verify it, which is one of the practical benefits of licensing.
