High RTP slot games are the games with the lowest house edge. For your convenience, we have highlighted for you the top 15 highest RTP slots currently available to be played, this includes four 99% RTP slots which offer the lowest house edge of any casino slots.

All casino games have a slight house edge which means the odds always favour the casino. However, some favour the house more than others. Although slot machines are not typically games which usually favour the player there are some which go as high as 99%, meaning the house only has a 1% edge. We conducted tests on all of the slots on this page and we have the RTP data to prove it too. You should be aware that even high RTP slots can massively perform in short sessions, as shown in our 10,000 spin RTP experiment. At the same time, our experiment also showed that lower RTP’s can also overperform in short sessions.

BEST HIGH RTP SLOTS IN 2026

Below I have written for you mini-reviews of each of the highest RTP slot machines. I have played and tested each of these slots myself in order to provide you with real evidence and expertise of what these slots are like to play. I have also included where you can play each of them so that you can play them for yourself if you would like to.

1. UGGA BUGGA BY PLAYTECH (RTP: 99.07%)

SlotsHawk Score:

• 3/10 volatility
• 2/10 bankroll requirement
• 7/10 win potential

Ugga Bugga remains an utterly unique slot due to its unique reels and rows which are called ‘held reels’. When you spin, only one of the rows will spin. Of the three symbols that land, you will get to choose the option to hold one of them, you will then see the symbol appear across the remaining rows when you complete the second and final part of the spin. You can also choose not to hold a symbol.

There aren’t any other slots that we can think of that have this feature. The maximum possible payout of 1,000x was one of the highest available back when Ugga Bugga was first released. Compared to some NoLimit City and other high volatility slots, Ugga Bugga is completely different. But it is a low volatility slot with the highest RTP of any slot in the world so we recommend trying it for yourself.

• Slot Game: Ugga Bugga
• Developer: Playtech
• RTP: 99.07%
• Maximum Payout/Multiplier: 1,000x
• Volatility: Low
• Maximum Bet: 250
• Minimum Bet: 0.10
• Paylines: 10
• Bonus Features: Bonus Game, Scatter Symbols, Free Spins, Mobile Friendly

Play at: MrQ Casino

2. BOOK OF 99 BY RELAX GAMING (RTP: 99.00%)

SlotsHawk Score:

• 7/10 volatility
• 7/10 bankroll requirement
• 6/10 win potential

Book of 99 revolves around a trail which appears to the left of the main grid which counts up to 99. Once you land enough symbols to reach the 99 steps, you will trigger the Book of 99 bonus round. When we played Book of 99 for real money, we did get rather frustrated waiting for the 99 steps because it does take quite a while. With that being said, you can still trigger the bonus game by landing three or more scatters.

Book of 99 has a max payout potential of 5,000x your stake as well as expanding wild symbols and respins. In addition, Book of 99 is a rather rare slot game, but it is available to be played at Casumo Casino.

• Slot Game: Book of 99
• Developer: Relax Gaming
• RTP: 99.00%
• Maximum Payout/Multiplier: 5,000x
• Volatility: High
• Maximum Bet: £5
• Minimum Bet: £ 0.10
• Paylines: 10
• Bonus Features: Bonus Game, Scatter Symbols, Free Spins, Expanding Wild Symbols, Respins, Mobile Friendly

Play at: Casumo Casino

3. OOH AAH DRACULA BY BARCREST (RTP: 99.00%)

SlotsHawk Score:

• 5/10 volatility
• 4/10 bankroll requirement
• 5/10 win potential

Ooh Aah Dracula is a fun and amusing take on a horror themed slot game. Played on five reels and three rows with 10 paylines, Ooh Aah Dracula is a slot which is sort of caught between the new and the old as its modern mechanics of stacked wilds somewhat goes against the rather basic base game.

You should know that the 99% RTP is only available in big bet Mode. This means that in order to play with the 99% RTP, you must bet the maximum amount of £5 per spin.

• Slot Game: Ooh Aah Dracula
• Developer: Barcrest
• RTP: 99.00% (Big Bet Mode)
• Maximum Payout/Multiplier: 457x
• Volatility: Medium
• Maximum Bet: £5
• Minimum Bet: £0.10
• Paylines: 10
• Bonus Features: Bonus Game, Scatter Symbols, Free Spins, Stacked Wild Symbols, Respins, Big Bet Mode, Mobile Friendly

Play at: All British Casino

4. MEGA JOKER BY NETENT (RTP: 99.00%)

SlotsHawk Score:

• 7.5/10 volatility
• 6/10 bankroll requirement
• 5/10 win potential

Mega Joker has been stylized in such a way to make the player feel like they are playing a real slot machine. The style is a old-fashioned slot machines too so this one should appeal to the romantic slot players among you. Mega Joker is best known as a progressive jackpot slot which has in the past triggered for over £100,000.

Due to the high RTP of 99%, the jackpot is rarely triggered but this does therefore mean that there are plenty of opportunities for base game wins. With that being said, to ensure the 99% RTP is active, you need to play Mega Joker on big bet mode, so this is similar to Ooh Aah Dracula. Big Bet Mode is activated when you bet at least £5 per spin.

• Slot Game: Mega Joker
• Developer: NetEnt
• RTP: 99.00% (Big Bet Mode)
• Maximum Payout/Multiplier: 200x
• Volatility: High
• Maximum Bet: £10
• Minimum Bet: £0.10
• Paylines: 5
• Bonus Features: Jackpot, Multipliers, Mobile Friendly

Play at: All British Casino

5. JACKPOT 6000 BY NETENT (RTP: 98.86%)

SlotsHawk Score:

• 7/10 volatility
• 3/10 bankroll requirement
• 5.5/10 win potential

Similar to Mega Joker in the sense that the style here is suppose to make you feel like you are playing a real slot machine in a land-based casino, Jackpot 6000 also comes with a progressive jackpot which can be triggered randomly at any time. The Return to Player of jackpot 6000 is a little lower compared to the slots we have already spoken about at 98.86%, but you do not have to play Jackpot 6000 on Big Bet Mode to get this RTP.

You can bet from as little as 10p per spin on Jackpot 6000 and you will still get its optimal RTP. The maximum payout is 6000 times your bet too which is where this slot gets its name from!

• Slot Game: Jackpot 6000
• Developer: NetEnt
• RTP: 98.86% (Big Bet Mode)
• Maximum Payout/Multiplier: 6,000x
• Volatility: High
• Maximum Bet: 2
• Minimum Bet: 0.10
• Paylines: 5
• Bonus Features: Jackpot, Multipliers, Mobile Friendly

Play at: Pub Casino

6. 1429 UNCHARTED SEAS BY THUNDERKICK (RTP: 98.60%)

SlotsHawk Score:

• 2/10 volatility
• 2/10 bankroll requirement
• 8/10 win potential

Played on a classic 5×3 grid with 25 paylines, 1429 Uncharted Seas is the lowest variance slot game with the highest RTP. Cartography lovers will enjoy this slot given its nautical theme and the fact that the grid looks like a giant but ancient map of the seas. The main mechanic in 1429 Uncharted Seas are the expanding wilds and there is also a free spins game, of course.

• Slot Game: 1429 Uncharted Seas
• Developer: Thunderkick
• RTP: 98.60%
• Maximum Payout/Multiplier: 1,250x
• Volatility: Low
• Maximum Bet: 5
• Minimum Bet: 0.10
• Paylines: 25
• Bonus Features: Expanding wild symbols, mobile friendly, free spins

Play at: Hyper Casino

7. DR JEKYLL GOES WILD BY SCIENTIFIC GAMES (RTP: 98.20%)

SlotsHawk Score:

• 2/10 volatility
• 2/10 bankroll requirement
• 4/10 win potential

Dr Jekyll Goes Wild looks similar to Ooh Aah Dracula and it plays like it a bit too. The RTP is only available when you play in Big Bet Mode, so that means betting a minimum of £5 per spin. One of my favourite aspects of Dr Jekyll Goes Wild is the fact that you can trigger 75 free spins if you manage to land five scatter symbols – easier said than done of course.

Dr Jekyll Goes Wild is themed around the horror character of the same name. The idea from the developers is to make the player feel like you are deep in the streets of London during the Victorian times and I think they have done a great job.

• Slot Game: Dr Jekyll Goes Wild
• Developer: Scientific Games
• RTP: 98.20% (Big Bet Mode)
• Maximum Payout/Multiplier: 500x
• Volatility: Low
• Maximum Bet: 100
• Minimum Bet: 0.10
• Paylines: 5
• Bonus Features: Free spins, Multipliers, Mobile Friendly

Play at: All British Casino

8. MARCHING LEGIONS BY RELAX GAMING (RTP: 98.12%)

SlotsHawk Score:

• 8/10 volatility
• 7/10 bankroll requirement
• 7.5/10 win potential

When we conducted our real RTP test, Marching Legions was actually one of the games which underperformed the most. After spinning 500 times, the RTP came out at just 70,88% despite its advertised RTP of 98.12%. This just proves that a slots RTP will always vary especially when combined with variance levels – Marching Legions has high variance.

The 3D design really makes Marching Legions stand out from the rest. In fact, I think that this is probably one of the most appealing slots out there. There are plenty of great slot features here too including repsins and a Nudge feature. As well as the superior RTP, there is also a maximum potential payout of 10,000x.

• Slot Game: Marching Legions
• Developer: Relax Gaming
• RTP: 98.12%
• Maximum Payout/Multiplier: 10,000x
• Volatility: High
• Maximum Bet: £5
• Minimum Bet: £0.10
• Paylines: 243
• Bonus Features: Free Spins, Bonus Game, Multipliers, Wild Symbols, Scatter Symbols, Nudge Feature, Respins, Stacked Wild Symbols, Mobile Friendly

Play at: NYspins Casino

9. THE CATFATHER BY PRAGMATIC PLAY (RTP: 98.10%)

SlotsHawk Score:

• 5/10 volatility
• 6/10 bankroll requirement
• 8/10 win potential

The Catfather has a lot more to offer than just its insanely high RTP of 98.10%. With stacked wild symbols and progressive multipliers, when we tested this slot for real money we really managed to rack up the wins. The medium variance helps a lot here as it means that you won’t go many spins without hitting a win and the max win potential can go all the way up to 2,251 times your bet. We hit a multiplier of 60x and 42x.

The Catfather is played on 5 reels and 3 rows with 9 paylines so you can treat it like a usual video slot. However, the mechanics help to give this game another dimension, especially with the fun cat symbols.

• Slot Game: The Catfather
• Developer: Pragmatic Play
• RTP: 98.10%
• Maximum Payout/Multiplier: 2,251x
• Volatility: Medium
• Maximum Bet: £5
• Minimum Bet: £0.10
• Paylines: 9
• Bonus Features: Free spins, Bonus game, Multipliers, Scatter symbols, Wild symbols, Stacked wild symbols, Progressive multipliers

10. TEST YOUR STRENGTH: LUCKY TRAP BY DESIGN WORKS GAMING (RTP: 98.05%)

SlotsHawk Score:

• 6.5/10 volatility
• 8/10 bankroll requirement
• 9.5/10 win potential

Test Your Strength Lucky Tap is the best payout high RTP slot with a max payout of 71,785 times your bet. This is not your typical slot either, there are not rows, reels or paylines. Test Your Strength Lucky Tap likely inspired NoLimit City’s crash games.

The mechanic here is instant wins and the higher the bet you make, the larger the potential wins will be. Everything here is luck-based but we certainly recommend betting small to begin with so that you can get to learn how the slot works.

• Slot Game: Test Your Strength
• Developer: Design Works Gaming
• RTP: 98.05%
• Maximum Payout/Multiplier: 71,785x
• Volatility: Medium
• Maximum Bet: £5
• Minimum Bet: £0.10
• Bonus Features: Free Spins, Bonus Game, Multipliers, Wild Symbols, Scatter Symbols, Instant Wins, Mobile Friendly

Play at: Grand Ivy Casino

11. TORO WILDS REEL BY SYNOT GAMES (RTP: 98.03%)

SlotsHawk Score:

• 6/10 volatility
• 6/10 bankroll requirement
• 5.5/10 win potential

Why Synot Games decided to release a slot themed around Spanish bullfighting we do not know, but regardless the development did an excellent job here with Toro Wilds Reel which has an RTP available of 98.03% without Big bet Mode. The only thing you need to know is that casino sites are able to change the RTP of this one so make sure to play it at Casumo Casino where we have tested Toro Wilds Reel and can confirm you can play it at its optimal RTP.

• Slot Game: Torro Wilds Reel
• Developer: Synot Games
• RTP: 98.03%
• Maximum Payout/Multiplier: 2,000x
• Volatility: Medium
• Maximum Bet: £5
• Minimum Bet: £0.20
• Paylines: 50
• Bonus Features: Free Spins, Bonus Game, Multipliers, Wild Symbols, Scatter Symbols, Mobile Friendly

Play at: Casumo Casino

12. DRAGON DANCE BY MICROGAMING (RTP: 98.00%)

SlotsHawk Score:

• 5.5/10 volatility
• 4/10 bankroll requirement
• 7/10 win potential

One of the easiest high RTP slot machines to play on this list and a good one for newbies and beginners, Dragon Dance is played on a simple 5×3 grid with 243 paylines. Match five of any of the symbols for a payout and hit three or more scatters to activate the bonus game. During the free spins bonus, all payouts will have x3 multipliers and respins are available too.

When we tested Dragon Dance at Casumo Casino, we managed one big win when we hit four drum player symbols and a wild on a payline for a 40x payout. For the majority of our test of Dragon Dance, we were betting 50p per spin. Although at one point we did raise our bet to £1 per spin, all of which you can see in the video above. We triggered x2 free spins bonus games overall, one of which we won a decent sum of money, the other we did not win much at all. The bonus game is triggered by matching 3, 4 or 5 scatter symbols. We matched three scatters two times giving us 15 free spins each game.

• Slot Game: Dragon Dance
• Developer: Microgaming
• RTP: 98.12%
• Maximum Payout/Multiplier: 495x
• Volatility: Medium
• Maximum Bet: £5

13. RAINBOW RICHES PICK N’ MIX BY BARCREST (RTP: 98.00%)

SlotsHawk Score:

• 6/10 volatility
• 3/10 bankroll requirement
• 9/10 win potential

Quite simply one of the greatest slot games of all time, Rainbow Riches Pick N’ Mix is excellent in its simplicity but also how action-packed it is. Rainbow Riches Pick N’ Mix was included in SlotsHawk’s real RTP test where during our 500 spins, we won almost £100. There are five different bonus games in Rainbow Riches Pick N’ Mix which is what makes it truly unique, in addition you can choose one of the bonuses before you spin which will allow yo to trigger that one more often. We recommend the Road to Riches feature where you can trigger big multipliers.

• Slot Game: Rainbow Riches Pick N Mix
• Developer: Barcrest
• RTP: 98.00%
• Maximum Payout/Multiplier: £250,000
• Volatility: Medium

• 9/10 volatility
• 9/10 bankroll requirement
• 8/10 win potential

One of the highest RTP Megaways slots available, Blood Suckers Megaways is one of only a few slots on SlotsHawk which has a 5/5 rating. Played on 2-7 reels with 6 rows and 117,649 paylines, this is a great slot if you are looking for a high-risk slot with high RTP due to its very high variance level.

We tested Blood Suckers Megaways at Casumo Casino where we can confirm that the maximum payout is 20,521 times your bet although we only managed to hit a 45x win which was during the free spins game.

NEWEST HIGH RTP ONLINE SLOTS

Although slots with high RTP’s of 97% above are rare, the Slotshawk team always keeps an eye-out on all new slot releases so that if one is released, we will be able to tell you about it.

Below, you will find our list of the most recently released slots with above average RTP’s.

Slot Game	RTP
Fonzo’s Feline Fortunes	96.50%
Blazin’ Guns	96.23%

ARE HIGH RTP SLOTS BETTER?

To put this simply, no, slots with high RTP they are not necessarily better to play. It depends on your definition of better. Yes, over millions of spins, the higher the RTP of a slot, the more likely you’ll be to have your money returned to you. But there are a variety of factors involved including variance level which has a strong determining factor as to how likely you are to win from any given slot.

With that being said, if you are stuck on finding a slot to play, you won’t go wrong when picking one with an RTP of 97% or above.

BANKROLL TIPS FOR PLAYING HIGH RTP SLOT GAMES

We advise not diving straight into playing high RTP slots or any slot games for that matter. To give you the best possible chance of an enjoyable experience, you should commit to a maximum spend per session and a maximum session time limit.

• Session time and bankroll – In terms of spins, our recommended session limit would be a minimum of 300 spins. Although it varies by slot, it takes an average of 10 minutes per 100 spins so you should not start playing a session if you are strapped for time or in a rush. In addition, once you reach your session limit, you should stop or at least take a break, even if you are winning. Maintaining control of yourself and the session is what separates winning players from losing ones.
• Lower stake sizing – The size of your stake depends entirely on your bankroll. Have a bankroll of £500 or lower? Bet no more than £0.20 per spin. You will be surprised how quickly it is to run out of money, especially if you are playing slots with high variance.
• Don’t chase bonus buys – In some slots you will be given the option to buy another spin with your winnings – this is especially common in some NoLimit slots at the end of a bonus game. We recommend not taking this option, when you get a win, don’t risk losing it.
• Use the demo mode to your advantage – You will never be at a disadvantage if you play via demo mode first. This is especially important if you are trying out a slot for the first time. Play on demo mode first so that you know how the slot works and test it for free.

EXPECTED SESSION EXPERIENCE

To give you an example of a session playing high rtp slots, here is a visual example of what you can expect from a 100 spin session:

• This will vary depending on the slot variance. High variance you can expect 70 dead spins and 30 winning spins. Low variance and you can expect 30 dead spins and 70 winning spins.

WHO SHOULD PLAY HIGH RTP SLOT MACHINES?

PLAYER TYPE	SUITABILITY
Bonus hunters	Maybe
Casual players	Yes
Low-risk players	Yes
Big win chasers	Maybe
Small bankroll players	Yes

REAL DATA TESTING

Short-term results can vary massively from advertised RTP figures. Some high RTP slots returned as low as 54.90% during a 500-spin session, whilst others exceeded 170% RTP due to large bonus payouts.

• If you are looking for the biggest payouts: The higher the volatility of the slot, the higher the chance of hitting the highest multipliers. Of course, this is by no means guaranteed, but if that’s what you are after then these slots should appeal to you.
• It helps to either bet small or ensure that you have a large enough bankroll that can withstand the swings.
• Experienced slots players: Players who already know the ins and outs of slots as well as the pros and cons of the different slot features are at an advantage when it comes to any slot games including ones with optimal RTP.

Bet smart. A strategy which we always use is changing the size of your bets based on how well you are doing. We always start by betting small but if we hit some early wins, then we will increase our bets in the hope that we keep getting lucky but because we have increased our bets, our payouts will be worth even more.

YOU SHOULD PLAY THE HIGH RTP SLOTS WHICH HAVE STANDOUT FEATURES AND EASY TO TRIGGER BONUS GAMES

Our RTP testing proved that the sots which generated the highest RTP’s and biggest wins, were the ones which had bonus games which were easier to trigger. If you are spinning through 500 spins, you really want to be triggering at least four bonus games. Anything less and unless you get insanely lucky, you will likely be losing money. In the majority of slots, it is during the bonus rounds where the RTP level is at its highest and the bigger payous are most common.

A good example of a high RTP slot with an easy to trigger bonus game is Dragon Dance.

ADJUSTABLE RTP RATES

Some of the most well-known slot providers that create slots with adjustable RTP include NetEnt, Microgaming, Play’n GO, NoLimit City, Pragmatic Play and Red Tiger Gaming.

SLOTS WITH THE BEST PAYOUTS

Here are three stronger paying slots – these offer the best potential payouts from a single spin. All of them offer a minimum potential payout of 100,000 x on a single spin.

• Tombstone RIP by NoLimit City: With one of the highest volatility levels ever and played on a 2-3-3-3-1 grid with 108 paylines, Tombstone RIP is big on both features and payouts. It comes with xNudge, xSplit and xBet features and a 9.08% hit rate. Cowboy multipliers include 999x wins too. The payouts can rise all the way up to 300,000x and the RTP is 96.08%.

THE RELATIONSHIP BETWEEN VOLATILITY AND RTP

Low variance slots are programmed in a way which will give you frequent smaller hits, enabling you to play many spins without the fear of busting. These are games designed for longer sessions as the swings are likely to be much less in comparison with more volatile games.

High variance slots can provide really large hits at the expense of needing to play for a while to access the games bonus features in order to hit the big wins. See which slots offer the biggest volatility swings for yourself via our page dedicated to the top 10 high volatility slots.

In general, games with a higher RTP are always better to play than the games with a lower percentage.

COMMON MISTAKES

There are certain mistakes that even the most experienced players can make when it comes to playing slot games online. here are some mistakes to avoid:

• Thinking RTP and payouts are the same: You should not be confused between a slots RTP and maximum payout – the are two different things. A slots RTP is the amount it will pay back over an amount of time in comparison to how much you put into the machine. The maximum payout is the absolutely maximum multiplier any given slot machine can trigger.
• Thinking RTP and variance is the same: RTP and variance are also two completely different aspects of online slot games. Variance decides how often a slot game will payout and how big or small the payout will be.
• Raising stakes after losses: it can be easy to go on tilt and increase your bets if you are going through a string of losses or dead spins. The thinking here is usually that you are due a win soon so you may as well bet higher to give yourself a chance of a bigger win. However, slot games are completely and pay no attention to past results.
