We answer the questions:
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.
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.

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%.

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.

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.

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.

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.

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.
*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
(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.

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.

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.

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…
*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
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.
*First deposit only. 50 Free Spins on the Book of Dead slot. Min deposit £10. Excl. new players in N.I. Each Free Spin valued at 10p. OJO’s Rewards and Game Play policy applies read more
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!

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.

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.

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.

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 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?
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.
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.
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:
£189,000/£200,000 = 94.5% RTP
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.
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.
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.
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!
