RTP in Slots – Meaning & Calculation
Before we continue any further, we would like to clear all misunderstandings or questions our readers might be facing regarding the whole subject of RTP. So what is RTP? It is an abbreviation for return to player – a theoretical percentage, which shows what portion of the total bets made, you can expect to be returned in the form of winnings.
Most gamers look up those numbers and use them as an indicator of the probability of winning. Anyway, be aware that, RTP should be considered together with other metrics, such as house edge and variance in order to get a good perspective on what to expect. Plus, remember that even though a lot of players confuse house-edge and RTP, those two are something completely different.
But don’t worry, we’ll get to explain more and compare the two further along in this article. Meanwhile, you can take a look at the best payout casino sites in the UK, since we’re reviewing the topic. Lastly, here’s a brief table with some of the topics we’ll be discussing next:
RTP Testing & Verification
As we mentioned already, slots’ RTP% gets tested and verified early on, in the pre-launch phase. In addition to that, online casinos go through regular testing and payout audits, conducted by independent auditors. This is done so that players can be proven and guaranteed fairness and accuracy of the games. Below, we have listed some of the most reputable auditors, in case you’re interested and want to know more about them.
- eCOGRA
- iTech Labs
- GLI
The listed above are well-known third-party organisations that all the best real money casinos work with. And because we are aware they’re going to be new for most readers, here’s a little something for each one:

Slots Return to Player Compared to Other Games
It is no secret that if you’re playing with the main objective of winning money, some games are going to pay better. This is simply because certain categories have higher payout percentages and numbers. For instance, the average blackjack game has an RTP above 97% and, oftentimes, that number is within the 99%, while slots would normally be around 96%. In this regard, we have prepared the table below with games’ average values, so that you can compare slots to other casino games.
As was noted already, some games, like blackjack and live-dealer baccarat, have notoriously high RTPs and low house edge. However, don’t forget that they require more skills, whereas, for example, slot games are all about luck. Plus, even though the average RTP for slots is 96.63%, you can still find high RTP slots with RTP above 99%, as seen in our top 10 best RTP slots.
What Is Considered a High RTP Slot Percentage?
Speaking of the highest RTP slots, you might be wondering what then would be considered a low RTP and where’s the line. Well, anything below 94-95% is low. Slot games with an RTP above 97% are impressive, but of course harder to find. You can check down below the highest RTP online slots found at UK casinos:

Nevertheless, there are many classics like the Cleopatra slot, whose RTP is only 95.03% and is still extremely popular and very much loved amongst players. Hence, it’s not just the RTP that’s important. Sometimes it’s the special features, other times, it’s the iconic theme or something else that’s so good that makes gamers overlook the title’s lower RTP numbers.
House Edge vs. RTP Value
First off, probably the best way to separate and differentiate those two is by imagining them as the two sides of the same coin. The house edge shows the casino’s profit margin, whereas the RTP shows the return to the player percentage. Therefore, a high RTP means a low house edge and the other way around. The higher the RTP, the less the casino wins, at least in theory. As you already saw in our comparison of the highest RTP slots, there are additions with very low house edge, which makes them very alluring for gamblers.
Calculating the house edge, or the profit of the casino is super simple – it is the difference between 100% and the RTP percentage of the specific game.
RTP vs. Variance in Online Slots
The variance in online slots, also called volatility, is an important metric that should be taken into account together with the RTP. You’ve certainly heard before of low-variance and high-variance slots. Simply put, low-variance games are those whose payouts are distributed in regular small wins, while high-variance titles pay out mostly in large-sized wins, but much less often. Additionally, the higher the hit frequency of a slot, the more likely you are to catch winning combinations. However, high-hit frequency online slots do not necessarily pay out better, so keep that in mind.
High RTP Slot | Payout % | Slot Volatility | Official Site |
---|---|---|---|
Goblins Cave | 99.32 | Medium | Mr Vegas |
Gorilla Gold Megaways | 97.00 | High | 32Red |
Guns N’ Roses | 96.98 | Medium | 888casino |
Jack Hammer | 96.96 | Low | 888casino |
Immortal Romance | 96.86 | Medium | Mr Vegas |
Dead or Alive | 96.82 | High | 888casino |
Kathmandu | 96.70 | Low | 32Red |
Jurassic Park | 96.67 | High | 32Red |
Finn and the Swirly Spin | 96.62 | Medium | The Grand Ivy |
What’s interesting to know is that some slots have low variance in the base game, but high variance in the free spins and bonus round. That means you can expect regular small wins during regular play, and rare but substantial prizes during the special bonus features. Anyway, bonus features might take hundreds of spins to be triggered, so you need quite a bankroll to hit a big win.
One is for sure though – high-variance slots are riskier, but the prizes could really be huge. They would be a great fit for high rollers who really enjoy high-stakes casinos and games. Whereas, if you want to make the most of your budget, then you should bet on low-variance titles as they allow you to play longer. Last but not least, feel free to check out our guide on the top 10 slots with the best bonus games & features.
How Do Progressive Jackpots Influence the RTP Level?
Progressive jackpot slots have lower RTP values, compared to the standard versions, because a part of each bet, made on the game goes to the progressive jackpot pot. For example, one of the most popular jackpot games ever – Mega Moolah, only has an RTP of 88.12%. So, even though the base game in progressive slots pays off less, the accumulated massive jackpot goes to a single winner which still sounds like a good deal, right?
Online Slot | Jackpot RTP | Standard RTP |
---|---|---|
Irish Riches Megaways | 95.93% | 96.42% |
Cleopatra | 95.13% | 95.70% |
Hall of Gods | 95.30% | 95.50% |
Deal or no Deal | 93.83% | 95.06% |
Mega Moolah | 88.12% | 88.12% |
The table that we have prepared gives you a nice perspective of the idea. The standard slots versions have a better RTP, sometimes with just as little as 0.20%, which is the case with Hall of Gods. With Deal or no Deal, the difference is a little bigger, with 93.83% in the jackpot version, and 95.06% in the standard game. However, we would like to remind you that what’s most important is having fun. Just make sure you’re enjoying the play, and whether you prefer standard slots or jackpots, it’s not what truly matters.
