What Does RTP Stand For?

If you’ve ever wondered what RTP stands for, the answer is it’s short for ‘Return to Player’. This is a number, expressed as a percentage, which indicates the odds of winning at a specific online slot game. It represents the percentage of bets that a player can expect to win back over their entire time playing that game. However, it is just an average and doesn’t convey the exact amount a player may win.

The RTP percentage is usually displayed next to each casino video game or in the paytable. For live casino games such as roulette and blackjack, the RTP is usually expressed as odds for each type of possible bet – and this page will cover both fully.

RTP Explained

If you are playing a slot game that has a stated RTP of 95% and you play 100 spins at £1 per bet, then you can expect to win back £95 (on average). The remaining £5 is what’s often referred to as the house edge, i.e. the money the casino makes from players wagering.

If things always worked exactly like this, then slot games would not be very attractive to players as they would constantly lose money each time they spin the reels. It’s important to understand that any RTP percentage given is calculated over millions of spins. Therefore, for a single player to hit the exact RTP percentage of a single slot game each time they play, it is highly unlikely.

For this reason, RTP is often referred to as ‘theoretical’. Every single spin from each player will contribute towards the RTP of a slot game over time, think of it as one big prize pool if you like. The money you lose during your gaming session could be going towards another player’s win or visa versa.

Sometimes the house will win more and sometimes, luckily, you will! Each spin is calculated using very complex Random Number Generators (RNGs) to ensure that all players get a fair chance of a win or loss. This is why you can play the same slot game and hit a big win one day and win nothing on another day; it’s just pure luck.

Examples of RTP

You should now understand what RTP is, and how the number represents spins taken over a long period of time. The table below has examples of slots with some of the lowest and highest RTP rates around. Though there is a huge difference between the highest and lowest, it is important to note that the vast majority of online slots fall within 1% of each other at around 96%.

Low RTP SlotsHigh RTP Slots
Tales of Egypt

The low RTP has not stopped this becoming a beloved part of Pragmatic Play’s repertoire but high rollers may want to avoid it.

RTP: 94.07%
Goblin’s Cave

Playtech are the masters of slots with high RTP – and Goblin’s Cave has an incredible return rate of over 99%! The game plays on a simple 3×3 grid.

RTP: 99.32%
deadmau5

This branded online slot from Microgaming has been a big hit since its 2020 release, though its 95.22% is underwhelming. The high volatility, though, means that big wins are possible.

RTP: 95.22%
Ocean Princess

Ocean Princess is another simple slot from Playtech that has a monstrously high RTP rate, though it lacks a bonus round.

RTP: 99.10%
Rainbow Riches

If Irish imagery is your thing then few games are more entertaining than the Rainbow Riches slot, which is available at multiple big-name casinos.

RTP: 95%
Mega Joker

The majority of NetEnt’s online slots are of average RTP but Mega Joker bucks that trend with a mammoth 99%.

Take a look at this data from the UK Gambling Commission. You can see how the real RTP you experience can vary by as much as 15% either way, and you only start to see a game hit the average after 1 million spins. Before any game is verified and released at UK casinos, it must go through strict testing procedures to prove the RTP.

House Edge

Players will often talk about the house edge in casino games. This is easy to calculate as it’s the remaining percentage after the RTP is deducted. If a slot game has a theoretical RTP of 96%, this would mean that the house edge is 4%. This percentage is the casino’s profit and would be shared between themselves and the game provider in an agreed revenue split.

Knowing this, players are always on the hunt for casino games that offer the highest RTP and smallest house edge. Although there are some slots with a very small house edge, it’s actually table games that can provide some of the best odds for players.

French Roulette offers an average RTP of 98.65%, Baccarat 98.99%, Blackjack 99.54% and Craps 98.64%. These would all beat most slot games hands down in offering the smallest house edge at an online casino.

RTP Slots?

Rules set out by casino licensing organisations mean that players should always be able to find out the RTP of any slot game they want to play. This may be mentioned in the game description by the casino, and you might be able to sort slots by their RTP stats. Otherwise, opening up the paytable in any slot should show the game’s given RTP percentage. Any online slot game reviews will usually mention the RTP too.

Some game providers might be known for offering higher or lower RTP slots, but overall it is a mixed bag. Game providers usually look to appeal to the broadest range of players possible, so making games with varying RTP percentages is crucial to this.

Slot games may have a variable RTP which can be adjusted by the casino itself. In this case, you could play the same slot game at two different online casinos and experience a different RTP at each one. In-game features might also affect the slot’s RTP. For example, a hi-roller mode or a special bonus game might have a separate rating to the main game.

Another factor that can affect the RTP of a single slot is the amount you bet. Some games will offer you a more favourable percentage for bigger bets per spin or when using the max bet feature. These slots are good for high rollers. As mentioned, the RTP is just a theoretical average calculated over millions of spins. It’s always important to gamble responsibly and only bet what you can afford to lose, and consider other factors such as game volatility.

High RTP Slots – Do They Exist?

High RTP slots are the top games at online casinos because of the smaller house edge that they offer to players. When playing casino games, any perceived advantage that a player might gain will add value to a specific game. Therefore, it’s no coincidence that some of the most popular online slot games are also those which have the highest RTP percentage.

Most slots have RTPs of somewhere between 94% and 97%; this includes many favourites such as the Mega Moolah slot, which is offered by the majority of top casinos for UK players.

Slots with an above-average RTP are less common, and those with 98% or above are very rare indeed. We’ll now take a look at some of the higher Return to Player slots and what they offer.

Fans rave about the bonus features and sticky wilds here which can lead to some potentially epic wins. Those sticky wilds will lead the way, giving you an additional 5 free spins once the bonus round is active.

Rare 98% RTP & 99% RTP Slots

Finding slots with an RTP north of 98% is an incredibly difficult task to undertake because they give online casinos such a slim house edge. However, below we have outlined one of the best around.

Ugga Bugga – 99.1% RTP

Ugga Bugga RTP

This simple 3 reel, 10 payline slot from Playtech is easy to play. The lack of bonus features here is a blessing for any players new to the world of slots who are looking for an amazing RTP percentage. The key feature here is the ability to hold symbols on the reels in the style of classic fruit machines. Land a reel full of symbols, and you’ll get the option to hold that symbol over the reel for the next spin giving increased chances of a win. It’s just a shame that this slot isn’t optimised for mobile devices so can’t easily be played on the go.

RTP Table Games

RTP Table Games

Now that we’ve discussed RTP in slot games, how about in other games? Do all table games have Return to Player percentages and how do they compare to slot games? The simple answer is yes, all table games have RTPs like slots, and they usually have a much smaller house edge than slot games. Table games and live casino games can have an overall RTP as well as odds for specific bets, such as straight number bets (35:1) or red/black bets (1:1) in Roulette.

Table games can consistently offer high RTP percentages, particularly when compared to most online slot games. Because these games are played with a specific set of rules, numbers, or cards it’s easier to have a stable RTP. Professional players and serious players would choose table games over slots any day. Although the exact RTP might vary with some minor tweaks in the game format, the average RTP for French Roulette is 98.65%, Baccarat is 98.99%, Blackjack is 99.54%, and Craps comes in at 98.64%. This goes a long way to explaining why live blackjack is the game that most well-seasoned players flock to at many online casinos.

Why does RTP matter?

RTP is a big deal for players because it gives a theoretical indication of their chances of winning on a specific casino game. The theory follows that the smaller the house edge is, the bigger the chances of landing a win.

However, this can only ever be a theoretical stat, and the outcome of any casino game is down to pure luck. This is especially true for online slot games where Random Number Generators are used to ensure that the outcome of any single spin is truly randomised.

Does Hit Frequency or Volatility Influence the RTP?

Some players believe that hit frequency will give a better insight into when and how a casino game is going to payout. This term gives players a number, expressed as a percentage, which indicates how many bets out of 100 will payout on a specific casino game.

Volatility (or variance) of slots, is a stat also used by players to try and predict the likelihood of a game paying out. This is expressed as being either low, medium or high and indicates how often players can expect payouts from a slot. Low variance slots pay out more often but normally award smaller wins. Conversely, highly volatile slots pay out less often but the wins are usually bigger.

It’s a common myth that either or both of these stats affect the RTP of an individual casino game. They have no bearing on the RTP percentage, and equally, the RTP has no effect on the volatility or hit rate of any slot.

Conclusion

We’ve now seen that slots tend to offer lower RTPs than table games. We’ve also seen what RTP is and how players use it to try and predict the likelihood of a win from various casino games. It’s important to remember that any Return to Player percentage is purely theoretical and therefore can’t be used as a guarantee for wins.

It’s always a good idea to look at any game overall and factor in the bonus features and gameplay required to trigger them. The features are often the thing that makes the RTP so high in the first place, but if they are fiendishly difficult to trigger then your funds may be better spent elsewhere.

The most important thing is to stick within your personal playing limits and have fun when playing casino games online. Make the best use of casino bonuses and don’t chase losses just because of a high RTP!
