Essentially, RTP refers to the Return to Player from a particular slot or casino game. In some ways, it’s the opposite of the House Edge. For example, the slot game Starburst has an RTP of 96.1%. This means that the House Edge will be 3.9%. Overall, the RTP is connected to the amount a player is expected to receive back from what they bet.
Don’t take this literally and believe that, for every £10 you stake, you are therefore going to win back £9.61. If this were the case, then the entire practice of gambling would be so predictable – and lose you money over the long run – that people would never bother playing. In reality, a player could stake £10, then receive a huge win. Or they could lose everything. This means that RTP isn’t as black and white as it seems. Let’s take a closer look.

Whenever you see an RTP percentage displayed on a game, such as a video slot, this refers to something commonly known as the theoretical RTP. When a slot is being created, the developers will make this figure part of the essence of the game. Every time the reels spin, the results will be determined by an RNG, or Random Number Generator. These results are completely random, and cannot be rigged or guessed. A better description of an RNG, however, would be to call it a Pseudo Random Number Generator. If the results were completely random, this would mean that a casino operator would have no way of ensuring they would make money from the enterprise. Consequently, a code is built into this pseudo random sequence of number generations, which will ensure that a house edge is part of an unlimited number of spins. To put this concept into practice, it’s best to go back to the Starburst slot example. Whenever you spin the reels, you will know there is a variance every time. You could land a big win, or lose everything. But if you keep spinning, and do so for a very long time – in fact, if you never stop – the average RTP will edge closer and closer to that figure of 96.1%.
The performance of slots was previously only required to be tested before their release, as before September 2016, regulators would only demand the RTP be examined once in the run-up to being released to the public. However, since this date, the UK Gambling Commission has required operators to monitor the ongoing performance of their slots. This is because the Commission stated it was possible that developers could have created games which had an RTP that went down over time, which would in turn benefit the operator by providing an increasing house edge. To achieve this, developers could include a hidden code or similar during the creation of the slot game. As a result, this leads to the concept of Actual RTP, and how this can be combined with Theoretical RTP.
The best way to demonstrate Actual RTP is to use an example, such as a casino overseeing the RTP for the Starburst slot. The Theoretical RTP is 96.1%, and the operator wishes to test this figure against the end of the month which has just concluded. When the site looks at the numbers, they will see that they built up £200,000 in turnover for this game from player bets. Players won a total of £189,00, meaning that the site made £11,000 in profit. To do the maths and work out the Actual RTP, you would need to divide 189,000 by 200,000. The answer is 0.945, which translates to 94.5% RTP. While this is beneficial for the casino, as they have gained over 1.5% more profit than usual, it means the players are not getting the return that the Theoretical RTP said they would. This form of variation is not unusual by any stretch of the imagination, and the more time that goes by, the closer to the Theoretical RTP this game will get.
It isn’t just the RTP that affects a player’s experience with slot games – it’s the volatility, or variance, too. In essence, two slots may have the same RTP, but one could be high variance while the other is low. High variance means that the slot will pay out huge amounts occasionally, while low variance means that smaller wins are gained more often. When a casino operator oversees how a slot is performing, they will take the volatility into consideration as well as the RTP. If you know how often payouts occur, and how big they are, this helps to explain the overall performance in terms of RTP. If it’s a high volatility slot, the results will be more drastic, and vice versa. This means that an operator can create a scale which factors in this variance in results. If the RTP is within a high threshold and a low threshold of the slot’s Theoretical RTP, it can be deemed a permissible result. The threshold will be looser for higher thresholds and tighter for low variance slots. That being said, the longer the monitoring period lasts, the closer its expected that these parameters will get smaller, edging further and further towards the Theoretical RTP.
If you’ve spent a fair amount of time browsing progressive slots to play, you may have noticed that lots of them offer large jackpots that don’t have as high an RTP. In fact, the figure may be in the low 90s or the high 80s. What’s behind this? Well, when a player triggers the jackpot, the slot will have to pay out a huge amount of money. This cash therefore has to be put aside over a long period of time in order to pay for that one lucky player’s huge win. As a result, the slot developer will achieve this by lowering the RTP so the money can be divided up in this way. In some ways, playing a progressive slot is like playing the lottery – and if you want to get more involved in the actual gameplay behind slots, it may be better to look for a non-progressive with a higher RTP.
Bear in mind that choosing a slot with a higher RTP is not a strategy that will guarantee larger wins. If you want to benefit from a long term gambling strategy, then the higher RTP games are definitely advised. Other factors can of course go into a decision, such as choosing a video slot because it appeals to you visually, or because it’s a branded theme of a movie or TV series you love. Overall, though, if you want to win back as much money as possible while also being in with the chance of landing that big win, go for as high an RTP as possible.
It’s often the case that a casino bonus will involve playing on slot machines, and the wagering requirements are often lowest for this type of game if you encounter a bonus which has different requirements for different kinds. What many people may not know is that the value of a casino bonus can be impacted by the slots you choose to play, along with their RTP. If you want to improve your chances of winning and completing the bonus wagering requirements, your best bet is to go with slots that have a higher RTP percentage. Whenever you go to claim a casino bonus, make sure you read the terms and conditions included in the small print. This is especially useful when it comes to evaluating the value of your bonus in relation to slots. Some operators will lessen the value of, or even ban, play on certain slots, with the reasoning being that they have an RTP which is higher than average. There is a way to work out how to gain an advantage over the casino, though – essentially, you would need to follow a formula whereby the wagering requirements are balanced against the RTP. If you have a bonus with a wagering requirement of 30x, your advantage can be obtained by playing slots which have an RTP of roughly 96.7% or higher. If the wagering requirement is 40x, then the RTP will need to be higher to compensate – in other words, around 97.5% or higher if you want to maintain this advantage.
Don’t forget that, when you’re considering an RTP percentage, this is connected to the portion of money which is paid back to players over a long period of time. It isn’t an instantly applicable number, and won’t work over a single bet. This may result in slot RTP rates not looking as attractive, but remember that anything can happen in the short term, so you need to focus on this possibility as well as the long term return average.
If you want to decide which slots are the most playable based on their RTP rate and no other factors, then it’s important to think in the long term. To keep playing over a more extensive timeframe, a good balance must be maintained. However, other criteria will affect a player’s likelihood of winning. For example, Hit Frequencies are often considered, and these are frequently confused with RTP rates.
It’s likely that the term Hit Frequencies isn’t new to you. Some people will mix them up with RTP rates, but this is incorrect as they are only a part of RTP rates. Many players will tell you that a slots game which displays its hit frequency is far more appealing than those which don’t. The difference between these two terms is as follows: RTP rates provide a theoretical percentage when it comes to the number of wagered stakes which will be paid out to players over the long term. Hit frequencies, on the other hand, will tell a player how often a winning spin will take place. As far as comparing the two, hit frequencies can be seen as more accurate when it comes to finding a game which will pay out on a regular basis.
On average, a slot machine will have a hit frequency rate between 9% and 25%. In other words, up to a quarter of spins will give you a win. This is part of the calculation behind RTP rate, but the hit frequency does not detail the size of these wins. To be more precise, they do not specify whether this win is a 1p win from a £1 bet, or a £500 win on a £1 bet. Both the likelihood of winning, and the amount you’re set to win each time, is subject to variance.
It’s common for people to consider slot variance and volatility to be the same as RTP rates. However, they aren’t, and they are more similar to hit frequencies in that they are merely part of the calculation behind the slot RTP rate. In essence, variance or volatility refers to the likelihood of a player winning, and how much those winnings will be worth compared to your stakes.
This is where more in-depth analysis comes into play. At first glance, a slot machine with an RTP rate of 85% may seem less lucrative than one with 95%. However, add variance and volatility to the equation and you may just get a different result. A slot with a lower RTP rate may actually result in bigger wins for players.
The three types of variance are low, medium and high. With low variance slots, these will often have high RTP rates. Players will win more often over the long term, but the game will not pay out large sums of cash very often. While you can win on many spins – because the hit frequency rates are high – the amount you actually take away after each win isn’t that big. You may have guessed that high variance slots have the opposite effect. These slot machines have low RTP rates, and wins are not paid out often due to the hit frequencies being low. That being said, when a player does land a win, it’s well worth the wait. The strategy players typically attempt to follow is sustaining a large enough balance that they can deal with continually losing until that patch is over and they land a big win. With medium variant slots, these are the most common games you’ll find on online casino sites. The hit frequencies, RTP rates and prizes are mid-range, so there isn’t too much volatility either way. As these are a safe option, they are popular with gamblers across the globe.
A similar term is slot volatility, and this refers to the amount of risk there is involved with a slot. All this means is that low variance slots have low volatility, medium variance slots are subject to medium volatility and high variance slots are highly volatile. Another phrase which may have come out is ‘high paying slots’. However, this concept doesn’t exist. A player may be lucky enough to win a good amount of money on a slot game and recommend it to a friend, but it doesn’t then follow that the friend will have a similar experience. The best strategy is to avoid any slots which are described as high paying, and instead seek out those which have low or high variance and volatility, according to your playing preferences.
RTP refers to the amount of money a player will get back from a slots game over time. However, there is a difference between theoretical and actual RTP. Furthermore, this term isn’t to be confused with hit frequencies or slot variance and volatility. These terms only form part of the overall RTP calculation. Hit frequencies are used more often by players as an indicator of how likely they are to win, but this figure doesn’t go into specifics.
Casino sites have a duty to constantly monitor the performance of their game RTP rates to ensure the house edge doesn’t gradually increase too much in their advantage. Due to factors such as volatility, the margin may vary slightly month on month, but should slowly edge towards the original RTP stated to be within the blueprint of the game. Progressive jackpots will have a lower RTP than non progressives, but there are particular circumstances where they can be well worth playing.

However, if you get four symbols, you win 25 times your stake, and if you get five symbols, you win 100 times your stake. You get ten free spins, and if you land three or more symbols, you get ten more free spins.
With the two enticing bonus features, and a high RTP of 98%, it’s no wonder why this title has been so popular for so many years.
1429 Uncharted Seas is a little unlike other sea-faring titles. This slot is based more on the early years of sea exploration, so you can sea old style maps, mermaids, ships and sea creatures.

It’s also worth noting that the highest paying symbol is the mermaid. This symbol can payout 50 times your stake. With these features, and an RTP of 97.6%, this title possibly isn’t getting the attention it deserves.
