What is RTP?

How do we know the RTP is correct?

Explanation of slot volatility

Why do progressive slots have a lower RTP?

Please bear in mind: this isn’t a definitive list of the highest RTP slots. These are the greatest online video slots in the world (in our opinion) but we’ve ordered them in terms of how well they payout. This list is for the benefit of players who may have heard of these famous slots, but aren’t sure how well they pay compared to each other. Here, we’ve done all the hard work for you.

With each slot listing, we’ll also give you a recommendation for a slot site or bingo site where you can play the slot. Of course, many of these slots are widely available, so these are just our best suggestions.

20. Mega moolah (microgaming) – 88%

This classic, animal themed slot has such a low RTP because it’s progressive. That means randomly, on any spin, you could win a huge jackpot. To learn more about why progressive slots have lower rtps, that don’t take the jackpot into consideration, scroll down past this list.

18. Thai flower (barcrest/SG gaming UK) – 95%

Thai flower is another slot that made the transition from pubs and brick & mortar casinos to the internet sphere. That, to some extent, shows in its fairly stingy 95% RTP. For an on the ground video slot, this is very good. Slots in vegas casinos rarely make it above 85%! However, times have moved on and the new mobile player expects something a little more impressive.

This famous pub slot machine made a seamless transition to the world of online casino. It was so successful in fact, that it has spawned many spin-offs and sequels. These include rainbow riches pick ‘n’ mix, which is thought to have a much higher RTP at 98%.

16. Cleopatra (IGT) – 95.03%

This IGT slot is one of the most searched online video slots in the whole UK. Too bad that people don’t seem to realise that its sequel, cleopatra plus, has an ever better RTP at 96.8%.

15. Fluffy favourites (eyecon) – 95.38%

The favoured slot of bingo players, fluffy has spawned multiple sequels and progressive slots. All the regular slots have exactly the same RTP, while the jackpot versions lose a few percentage points along the way.

14. Kitty glitter (IGT) – 95.4%

This slot would have, without a doubt, won the “best pun-named slots” countdown. Sadly, it’s rather middling when it comes to RTP. In this case, if I were you, I’d dump out the glitter tray and keep the cat outside.

Magical vegas

13. Foxin wins (nextgen) – 95.6%

Whether you’re an urban fox with access to a mobile, or an urbane fox with an excellent sense of style, you’re still going to be rather disappointed by the mediocre RTP of this popular nextgen slot.

12. Gonzo’s quest (netent) – 96%

When hollywood moves emblazon “based on a true story” on their credits, we are immediately suspicious. So what about this historical slot? The central figure is based on gonzalo pizarro who was a spanish conquistador in the 1500s. He explored/conquered peru, pillaging his way to the capital, cuzco, where he would eventually die.

Did he ever find el dorado? No. Pizarro gave up the expedition leaving his partner/rival, francisco de orellana to discover and explore the amazon river.

11. Wizard of oz (WMS) – 96%

If you turn left at kansas street, keep going until there’s a hard right down the yellow brick road. You’ll find your destination, this popular WMS slot, in oz. Or, as we’re recommending, casino heroes.

10. Starburst (netent) – 96.1%

Ubiquitous. If a bingo, slots, or casino site doesn’t have it, then you know something must be up. It continues to inspire direct ripoffs, including heartburst by eyecon. We’re not even going to recommend a site for this one because you can literally find it anywhere.

Arcade spins

9. Pink elephants (thunderkick) – 96.1%

One of the latest slots to feature on this list, and probably the first “alt-slot.” this is a thunderkick creation. It is an example of a high volatility slot that has an average-high RTP. The actual RTP (read more below) may appear to vary wildly because of the infrequent but sometimes large nature of the wins.

Unibet bingo - relax gaming

*you have to be 18+ to register. New cusotmers only. Bonus T&cs apply. Begambleaware.Org. Once you have registered and opted in to this offer, you will receive a 200% bonus up to £20 on your first deposit of £10 or more. The maximum bonus amount given is £20. Wagering x2 times for bingo. Read more

8. Rich wilde & the book of dead (play ‘N go) – 96.2%

(but some casinos offer a 94.17% version). There was some controversy surrounding this, with theories that UK regulated casinos had to re-evaluate their RTP rating after subsequent testing.

Slots rush

Full T&C's apply. Read more

7. Double bubble (gamesys) – 96.2%

This realistic/gamesys creation is pretty hard to find. But find it we have! We recommend virgin games below, but they recently relinquished their bingo games. So if you want to play double bubble and bingo, we recommend you head over to heart.

Virgin games - gamesys

Deposit & play £10, get 30 free spins on double bubble OR £50 free bingo

*new members only, must opt in. Min £10 deposit & wager. 30 day expiry from deposit.18+. Free spins: on double bubble. 1p coin size, max lines. Bingo: advertised ticket value based on £1 tickets. Game availability & restrictions apply. Read more

6. Twin spin (netent) – 96.6%

This slot has the same RTP as the later released twin spin deluxe. However, according to videoslots’ actual RTP measure, this original version has paid out better in recent times.

Casper games - jumpman

Deposit £10+, open the ghostly chest to win up to 500 free spins

*new players only, min deposit £10, £8 max win per 10 spins, max bonus conversion £250, 65x wagering requirements and full T&cs apply. Read more

5. Thunderstruck II (microgaming) – 96.7%

This slot’s RTP is pretty much the same as its predecessor. However, according to videoslots’ actual RTP estimator, the original thunderstruck has over 100% RTP! We can’t confirm or endorse this projection, but we think it’s very interesting that its out there in the world…

7casino

Deposit £10+, win up to 500 free spins

*UK only. Win up to 500 spins from mega wheel on 1st deposit. 24-hour expiry. Max bet £2.50, max spins win £8 per 10 spins, max bonus win £150, selected games & 65x wagering on winnings. Min deposit £10. No neteller/skrill. Deposit/withdrawal fees apply. Full T&cs apply. Read more

4. Dead or alive (netent) – 96.8%

Dead or alive’s 96.8% RTP is rather generous for a netent slot. Don’t let this opportunity go to waste. Like other big netent titles, it’s fairly pervasive. It would probably be more difficult NOT to find it.

Playojo

No wagering deal: deposit £10+, get a slot spin for every £1 deposited

New customer offer. T&cs apply. 18+. Please gamble responsibly. Read more

3. Immortal romance (microgaming) – 96.9%

Our bronze and silver medals have rather similar themes. But it seems that microgaming have been pipped to the post by netent yet again. The turn of the decade was a good time to be a vampire/vampire fan!

Zeus bingo - 15 network

Deposit £10+, open the loot chest & win up to 500 free spins + get 48 free bingo millions tickets

*new players only, min deposit £10, £8 max win per 10 spins, max bonus conversion £250, 65x wagering requirements and full T&cs apply. Read more

2. Blood suckers (netent) – 98%

Number 2 on our list is, of course, this netent slot with over 98% RTP. Unfortunately, this high RTP comes with some serious downsides. At pretty much every casino, if you look into the terms and conditions, you’ll see that playing blood suckers or its sequel blood suckers 2 will not count towards wagering requirements. This is because the casino believes the RTP is too high. Therefore, you have too good a chance of playing through the wagering and coming out the other side with winnings.

Still, if you’re no longer playing with bonus funds, blood suckers in our wholehearted recommendation. This is as close to even money a video slot will ever get. Except for our number 1.

Volt casino

Up to 300 cash spins, 2500 vollars & 1,000 crystals on 1st deposit - no wagering on spins!

*valid for new players registering from 24/02/2020 to 31/05/2020. Registration offer = 100 crystals & 500 vollars. Max rewards on 1st dep = 300 starburst cash spins, 2500 vollars & 1,000 crystals. Only available on 1st dep of min €20. Dep needs to be wagered at least once. Every €10 on 1st dep = 10 cash spins, x5 vollars and x2 crystals. No wagering on cash spin winnings. Max winnings = €300. Neteller & skrill deposits excluded. Listed gameplay excluded on first deposit when opting in for casino welcome offer. Further T&cs apply. Read more

1. 1429 uncharted seas (thunderkick) – 98.6%

The best RTP video slot you’ve never heard of? This extraordinary historical slot was created by thunderkick and has an almost 99% theoretical RTP. You may even learn some history along the way.

Fruity casa

Deposit £20+, get 100% up to £100 + 20 bonus spins on fruit shop

*18+. New players only. Minimum deposit of £10. Bonus spins are valid on fruit shop only and subject to 35x wagering, and must be used within 10 days, otherwise any unused bonus spins shall be removed. Bonus funds are 100% up to £100 and separate to cash funds. 35x bonus wagering requirements and only bonus funds count towards wagering contribution. £5 max bet with bonus. Bonus must be used within 30 days otherwise any unused bonus shall be removed. Terms apply. Begambleaware.Org read more

Bonus classic slots with amazing rtps

We didn’t want to include them in this list as they’re not proper video slots. However, mega joker and jackpot 6000 are two netent slots based on old, classic fruit machines. Mega joker has an unbelievable 99% theoretical RTP and jackpot 6000 is only just behind. If you’re willing to let go of the bells and whistles of video slots, then give these a try.

RTP: the definitive guide – updated: march 2020

What is RTP?

RTP is the “return to player” from a slot or game. It is, effectively, the inverse of the concept of “house edge.” take, for example, starburst which has an RTP of 96.1%. Therefore, the house edge is 3.9%. This means that you are “projected” to get back 96.1% of what you bet.

So for every £10 you stake, you will win back £9.61?

That is not the case. If it were, why would you bother gambling at all? In practice, of course, you could stake £10, and walk away with £80. Or you could even lose it all. So how does it work?

Theoretical RTP: an explanation

The RTP that a video slot quotes is something that is known as the theoretical RTP. When a slot is developed, the creators programme the RTP into the game’s DNA. Every slot spin is determined by a random number generator (or more accurately, a pseudo random number generator). The spins are random and cannot be rigged. (for more information, see this article called “are online casinos fixed?”).

However, if it were truly random, then there would be no guarantee that a casino or bingo site would make money. The gambling industry wouldn’t exist as it does today.

So, built into this pseudo randomness is a code that ensures a house edge over an infinite number of spins. If we go back to our original example of starburst, we know there’s variance every time we spin. We may win (sometimes big) or we may lose it all. However, if we keep spinning on and on into infinity, the average RTP will constantly get closer to that 96.1% figure.

How can we prove the RTP is correct, then?

In the past, regulators only demanded that a video slot get its RTP tested before its release. But in september 2016, the UK gambling commission announced that it would require operators to monitor the performance of their slots. The GC deemed it possible that developers could have created games with a deteriorating RTP over time. This could be achieved by hidden code or some other technique or mistake in the implementation or operation of the slot.

This is where the concept of the actual RTP comes in, and how we can marry the two together.

Actual RTP: example study

Let’s say a casino is monitoring starburst’s RTP. We know that the theoretical RTP is 96.1%, and the site is testing this against the month that just finished.

During this month, the casino accrued £200,000 in starburst turnover from player bets. In kind, players won a total of £189,000. Therefore, the slot site made a cheeky £11,000 in profit from starburst. In order to work out the actual RTP of starburst in the last month, you just perform this simple equation:

Good for the casino, that’s over 1.5% more profit. Bad for the players, who are not getting the bang for their buck that the theoretical RTP declared.

As we mentioned, this is a pretty standard variation. In theory, the more months that pass, the closer to the theoretical RTP we get.

Slot volatility & RTP: what’s the connection?

As we know, another factor in the player’s slot experience is the volatility (or variance). Two slots may have the same RTP at 96.1%, but one may be high variance and other low. So what does that mean?

High volatility slot: this means the slot will not pay out that frequently. But when it does, the wins will be much bigger. In essence, a high variance slot is “all or nothing.”

Low volatility slot: this slot will give wins much more frequently. However, they tend not to be as large. Starburst is a good example of a low variance slot. This is part of the reason why it is so popular.

Medium volatility slot: somewhere in the middle.

Therefore, when a casino is monitoring the performance of a video slot, they take volatility into consideration. The frequency and size of payouts will go help to explain a slots overall RTP performance. You would expect a low variance slot to stay closer to its theoretical RTP. A high volatility slot you expect to be more… volatile.

Thus, an operator can create expected parameters to factor this in. Provided the actual RTP falls often enough within a high threshold and a low threshold of the slot’s theoretical RTP, then it can be deemed kosher. For a high variance slot, the lower and higher threshold will be looser. For a low variance slot, they will be tighter. But the longer the monitor period, the more these parameters should shrink closer and closer to the theoretical RTP.

This example graph from the gambling commission demonstrates the process.

Why do progressive slots have lower rtps?

Often you’ll see that progressive slots that offer large jackpots will have much lower rtps. Either, they’ll be in low 90s or even the high 80s. The logic behind this is quite simple. When a player triggers the jackpot, a rare occurrence, it means the slot will have to pay out an abnormally large sum of money. Therefore, they have to put money aside in order to pay for somebody’s windfall. The slot developer will do this by lowering the RTP by a couple of percent and stashing this money. This way, when a player wins thousands, or sometimes millions of pounds, the developer can draw from this cash pile.

Thus, we believe you should think of progressive slots like playing the lottery. If you want to enjoy the act of spinning, then looks for a non-progressive slot that has a higher RTP. However, if you want to give yourself the chance of winning a life-changing amount of money, and you’re not so bothered about sustainability, then give a jackpot slot a spin.

How to choose a new slot

This is all to say that choosing a slot with a higher RTP will not guarantee you bigger wins. If you stake £100 on starburst, you could easily win more in a day than on blood suckers. However, playing blood suckers, with its 98% RTP, gives you a better chance of recouping your money. Therefore, in terms of long term gambling strategies, choosing slots with the highest rtps is a must.

You can, of course, choose the video slot you want. Maybe you like the look of it, or it’s a branded slot of a movie that you love. That’s absolutely fine; playing slots should be all about having a good time. Just remember, choosing a slot with 80% RTP just doesn’t make savvy business sense!

What does RTP mean?

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.

How does theoretical RTP work?

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%.

Does this mean RTP is inaccurate?

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.

How does actual RTP work?

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.

How is slot volatility connected to RTP?

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.

Progressive slots have lower rtps. Why is that?

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.

What should I consider when choosing a new slot?

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.

How does RTP impact bonus value?

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.

How RTP rates work - the specifics

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.

How to think of RTP rates

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.

Hit frequencies explained

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.

How does slot variance and volatility fit in?

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.

Top facts about RTP

If you’re playing a slot which is part of a franchise or big name, it will be more likely to have a low RTP rate. This is because game developers have to pay a lot of money to use the name and images from well-known titles such as marvel, jurassic park and the terminator. To compensate, the player ends up footing the bill for this cost over time via the lower RTP rate.

Higher paying slots come from providers like thunderkick, netent and microgaming. Those from playtech, ballys, yggdrasil, nextgen or WMS don’t have the same levels of payout.

Progressive slots will generally have the lowest RTP percentage, and to be precise, this will be around 10% lower than most of the highest paying games out there. To obtain decent slots gaming, avoid these types of games.

If the progressive slot is at an all-time high, or you are playing with bonus money, it can still be in your favour to play these games despite the lower RTP rate.

Choosing one of the best RTP slots to play is something most people do without thinking. They pick one based on their preferred casino site, the theme, the bonus features, or the overall gameplay. Very few players research the details, and that means that there’s a very important aspect that’s often overlooked.Most people forget to research how much the best rtp slots gives back to the player. The RTP, or return to player, is most often seen as a percentage. It tells you how big of a percentage the slot will pay back to the players. So if the slots have an RTP of 90%, then it will pay out £90 of every £100 to the players in various wins.

Looking for a slot machine in online casinos with a high return to player doesn’t mean that the other reasons for choosing a slot should be forgotten either. You can find RTP slots with the highest payout-rates, and impressive graphics, sounds and themes. Here are some of the best returns to player slot machines.

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.

Starburst slot by netent (98.5% RTP)

Netent has been providing some of the best slots for years and starburst slot is no different. Bearing a return to player rate of 96.1% it’s one of the slots with big jackpots. The game feels like playing in an arcade but its amazing earning potential and high RTP will make you take it very seriously.

In starburst, when you hit a wild it may give you up to three re-spins and with a little luck, over £50,000! The design is beautiful, the soundtrack is mesmerizing but in the end, with an RTP that high, it rarely matters.

What is slot games RTP?

Slot games RTP is the acronym for ‘return to player’ and it is always displayed as a percentage. This term basically implies how often a player is likely to win, therefore, the higher the percentage, the higher the chances of winning.

So how do we know that the return to player is fair for all slot games?

Well the gambling commission is making sure all the involved parties stick to the rules and all the suppliers and manufacturers of slot games are licensed and fully checked.

According to the UK gambling commission

The operator making gaming machines available for use, as well as the gaming machine suppliers and manufacturers, must be licensed by the gambling commission, or hold a permit issued by a local licensing authority.

Understanding RTP percentages

Now let’s have a look at the slots RTP meaning in more detail

When we take an RTP of 100%, it means that the probability of a player winning the game is equal to that of the house. If the RTP gets over 100% it is an implication that over time, the casino is losing money on the game.

There is no chance that there will be a slot game RTP of over 100% because there won’t be any reason for the casino to offer the game in the first place.

For example if a slot game has an RTP of 97%, then for every £100 wagered on this games from all players collectively £97 will be returned as winnings.

The slot games are programmed to average this RTP on the long term. So even if the return is slightly lower or slightly higher short term this will average out to the RTP of the game sooner or later

This is where one of our slot tips ( take the money and run) comes into practice as well!

This is why best payout slots matter

The higher RTP percentage of a slot game, the better it is for the player.

Lower RTP percentages are always expected in land based casinos. Hence, it is always best to play online games that offer RTP percentages of 94% and above.

Under no circumstance should you settle for something less than this simply because there is much competition and choice in online casinos. You can find and play the highest payout slot machines quite easy.

How is RTP calculated?

The following formula is used to calculate the RTP on a video slot machine:(total amount returned to players) / (total amount bet by players) = RTP

Note: the reason as to why a slot will never have an RTP of 100% is because this will most likely put the house out of business as they will make enormous losses.

Still, your chances as the player to make gains are high when the RTP is closer to 100% in the long term. So let’s dig in the list with the 10 highest rtp slot games.

Top 10 slots with the highest RTP – play with the best odds

By: cat marshall february 27, 2018

Whilst many people decide which slot to play based on the theme, special features or promotional offers, the savvy gamblers steer towards slots with the highest RTP. The house edge of online slot machines can vary widely, and it stands to reason that the lower the house edge, the better your chances of winning.

Of course, you should keep in mind that only the best slot sites to win offer high payout games from which you can take advantage. The return to player percentage of a game is measured over thousands of game rounds, and it stands to reason that the higher the RTP, the better the deal for the player. With this in mind, I have decided to create a list of the 10 online slots with the highest RTP.
