Introduction: WDW’s Top Slots by RTP
Welcome to WDW’s Top 20 RTP Slots. This dynamic ranking lists our favourite slots by their RTP, or Return to Player. When new slots launch, we try to add them. If you have recommendations for slots that you think we’re crazy to leave out, please get in touch via the comments. Below this list, we also have a full article explaining Slot RTP.
Current Slots Site with the Best RTPs
*1st dep. of £10-£50, max bonus £50 on selected slots; 30x wagering requirements on the sum of deposit & bonus applies. Max convertible to real is £250. T&C's Apply. 18+
We answer the questions:
- 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.
*UK only. Win up to 500 Free 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. No neteller/skrill. Deposit/withdrawal fees apply. Full T&Cs apply. read more
19. Clover Rollover (Playtech) – 93%
This slot is available at pretty much all Playtech slot sites and Virtue Fusion bingo sites. It remains very popular and highly sought after, despite having a pretty low return to player.
*Opt-in required, x1 per customer, new Bingo customers only. Min £5 stake, max £25 bonus with 4x Wagering Requirement. Bonus expires in 14 days from chat name registration. Games, currency, location, player restrictions & terms apply.
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.
*UK only. Win up to 500 Free 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. No Neteller/Skrill. Deposit/withdrawal fees apply. Full T&Cs apply
17. Rainbow Riches (Barcrest/Scientific Gaming) – 95%
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%.
Buzz Bingo - Virtue Fusion
Deposit & Spend £10, Get £40 Bingo Bonus & 10 Bonus Spins + Free Bingo Everyday
*Deposit & spend £10 on Bingo, get £40 online bingo bonus & 10 x 5p spins on Midnight Wilds. Stakes on Bingo Millions do not contribute towards bonus. 1st depositors only. Bonus is non withdrawable. T&Cs apply. 18+ BeGambleAware.org
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%.
Paddy Power Bingo - Virtue Fusion
Deposit & Spend £5, Get £10 Bingo Bonus & £15 Slot Bonus + 25 Free Spins
*New Customer Offer only. Deposit and spend £5 on bingo tickets in the Bingo Client within 30 days of joining Paddy Power Bingo. Get £10 paid as Bingo Bonus (x1 wagering requirement), £15 as Slots Bonus (x10 wagering requirement) & 25 Free Spins (£0.10/spin) on Mystery Reels Megaways game. 1 per customer. Your age and mobile number must be verified before you can avail of his offer.Full T&Cs apply.
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.
Mr Q - Standalone Site
Deposit £10, Get 30 Free Spins on Legend of the 5 Ninjas + Free Bingo for 24 Hours (Use code: WDWB30)
*30 Free Spins are credited upon your first deposit, valued at 25p per spin and to be used on Legend of the 5 Ninjas slot • Winnings are capped at £5 and have no wagering requirement • Minimum deposit £10 • New customers only • Full T&Cs apply.
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.
*1st dep. £20-£100, max bonus £100; on selected slots; cashout restrictions, 30x wagering requirements on the sum of deposit & bonus and T&C's Apply. 18+
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.
Betfred Bingo - Virtue Fusion
Deposit £10, Get £20 Bingo Bonus & £20 Slots Bonus + 50 Free Spins (Use code: BINGO90)
*New customers only. Register with promo code BINGO90. Minimum deposit and stake £10 on Bingo Tickets to qualify. 2x wagering on £20 Bingo Bonus and 20x wagering on £20 Slots Bonus. Game restrictions apply. 14-day expiry. Bonus Balance is used prior to Cash Balance. 50 Free Spins on Starburst credited within 24 hours of qualification. Free Spins expiry after 7 days. E-Wallet & Prepaid Card restrictions apply. SMS validation may be required. Full T&Cs apply.
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.
*Min. 1st dep. of £20-£50. Max bonus £50 on selected slots; 50x wagering on the sum of deposit & bonus applies. Max convertible to real is 5x bonus amount received. T&C's Apply. 18+
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.
*First-time depositors only (18+ UK exc.NI). Min Deposit £5. Max Offer 100% Bonus, up to £5 & 15Free Spins [Game of our choice]. Free Spins winnings are capped at £1.50 and credited as bonus funds with 40x wagering. requirements. . Bonus funds must be wagered 60x before withdrawal.

General withdrawal restrictions & full T&Cs apply. Valid until 31/12/2020.
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.
*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.
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.
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.
*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.
*New members only, must opt in. Min £10 deposit & wager. 30 day expiry from deposit.18+. Free Spins: on Paper Wins. 1p coin size, max lines. Bingo: Advertised ticket value based on £1 tickets. Game availability & restrictions apply.
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.
*New Players Only, Min Deposit £10, £8 Max Win Per 10 Spins, Max Bonus Conversion Equal To Lifetime Deposits (Up To £250), 65x Wagering Requirements And Full T&Cs Apply Here
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…
*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.
*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
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 Equal To Lifetime Deposits (Up To £250), 65x Wagering Requirements And Full T&Cs Apply Here
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.
Up to 300 Wager Free Cash Spins, 2x Your Deposit in Volt Crystals, 5x Your Deposit in Vollars
*For players registering from 24/02/2020 to 31/12/2020. Registration = 100 Crystals & 500 Vollars. Max Rewards on 1st Dep = 300 Book of Dead cash Spins, 2,500 Vollars & 1,000 Crystals. Only on 1st Dep of min £/€20. Dep needs to be wagered x1. Every €10 on 1st Dep = 10 Cash Spins, x5 Vollars & x2 Crystals. No wagering On Cash Spins wins. Max wins = £/€300. Neteller & Skrill deps. excluded. Listed gameplay excluded on 1st dep. 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.
*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: August 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:
£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.
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!
