HIGH RTP SLOTS – SLOTS WITH HIGH RTP RATES

Last Updated: December 2, 2023

Written by Stephen Cummings

This page will explain to you the importance of RTP in slots, as well as show you the top 15 high RTP slots. If you are short on time, we can tell you that Book of 99 is the highest RTP slot with an RTP of 99%.

RTP stands for return to player and is the theoretical amount which a player can expect to receive when playing a slot game. To quickly give you an explanation, Blood Suckers has an RTP of 98%, this means that in theory, for every £100 put into Blood Suckers, you will receive £98 in return. Therefore, the higher the RTP of a slot game, the more you can expect to win.

So, what makes a high RTP online slot? If a slot has an RTP of 97% or above, it can be considered as a slot with a high RTP. The table below showcases our favourite ones. Our list is based on playability, maximum payouts and of course, the return to player rate.

BEST HIGH RTP SLOTS IN 2023

After comparing RTP percentages, we have compiled this list of the best 15 high RTP slot games which you can play at online casinos. Our editor Jean Prince showcases his editors pick for you below:

EDITORS PICK: ESQUELETO EXPLOSIVO BY THUNDERKICK

The editor of SlotsHawk has chosen Esqueleto Explosivo as his favourite high RTP slot. His reasons are simple. First of all, it has an RTP of 97.60%, which qualifies it as having a high RTP. Secondly, Jean loves the theme and graphics. He is a fan of all things spooky and macabre which sums up the graphics rather well. Esqueleto Explosivo also has a high payout of up to 700x.

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

We regard Book of 99 as the best RTP slot in 2023 due to its RTP of 99% and its original and fun theme. With respins, retriggers and, of course, an immensely high return to player percentage, Book of 99 is an exceptional slot game.

Book of 99 also comes with a max payout potential of 5,000x your stake as well as expanding wild symbols and respins. Just be aware that Book of 99 is a high variance slot, so winning spins on the reels may sometimes be few and far between.

Features:

• Free spins
• Bonus game
• Stacked wild symbols
• Scatter symbols
• Respins
• Retriggers
• Multipliers
• Mobile friendly

Play at: Casumo Casino

2. MONOPOLY BIG EVENT (RTP: 99.00%) BY BARCREST

There are many Monopoly slots but Monopoly Big Event is the one with the highest RTP. However, the catch here is that you have to play the game on Big Bet mode to qualify for this RTP.

My recommendation is to play on the normal mode first so you can get used to how the game is played. The Big Bet mode has a house edge of only 1% though, so once you get the hang of playing, you should take advantage of the low house edge high RTP feature.

Features:

• Free spins
• Bonus game
• Progressive multipliers
• Wild symbols
• Autoplay
• Mobile friendly

Play at: Monopoly Casino

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

A fun design mixed with a dramatic soundtrack with the added addition of plenty of features, its RTP ensures that Ooh Aah Dracula remains one of my favourite slots to have ever been released!

This slot is played on a 5×3 reel set and is played on 10 paylines with free spins bonuses. Players also have access to WIlds and a pick and click type bonus game. High rollers get to play the high-roller option which triggers 5 spins at the given stake.

Features:

• Free spins
• Bonus game
• Stacked wild symbols
• Scatter symbols
• Autoplay
• Mobile friendly

Play at: Hyper Casino

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

In part due to its easy to use classic fruit machine style and progressive jackpot, the Mega Joker slot from NetEnt has been popular since its release in 2013. Played on 3 reels and 3 rows with 5 paylines, Mega Joker takes its inspiration from classic slot machines.

Mega Joker also attracts players thanks to its progressive jackpot.

Features:

• Bonus game
• Progressive jackpot
• Autoplay
• Mobile friendly

Play at: Pub Casino

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

Another RTP slot based on a traditional slot machine, Jackpot 6000 features both the bottom and top parts of a classic fruit machine. You will find traditional slot symbols such as the lemon, a cheery and of course the joker.

This is a high volatility slot, so be careful and don’t get carried away. However, thanks to its RTP, when you do hit a win, you should expect it to be a big one!

Features:

• Bonus game
• Wild symbols
• Autoplay
• Mobile friendly

Play at: Casumo Casino

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

Certainly one of the oldest slots in our expert guide, Dr Jekyll Goes Wild is themed around the mysterious Dr Jekyll. A rather spooky slot game, this one really has stood the test of time as it is still a popular game even now in 2023. The super high RTP of 98.20% can be accessed when you play on Big Bet mode, which is why we recommend Dr Jekyll Goes Wild as the best slot on this list for high rollers.

Despite being an older slot, there are still several nice features here including the opportunity to win up to 75 free spins.

Features:

• Free spins
• Big Bet mode
• Wild symbols
• Scatter symbols
• Autoplay

Play at: Fun Casino

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

A fun and rather sophisticated Roman themed slot, Marching Legions was released by Relax Gaming in 2020 and comes with a handsome RTP of 98.12%. 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. Marching Legions is also a high variance slot with an average hit rate of 25.62% – you’ll trigger a winning spin 1 in every 4 spins.

Features:

• Bonus game
• Free spins
• Respins
• Nudge feature
• Stack
• Autoplay

Play at: Casumo Casino

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

If you are a cat love then this is the slot for you! This highly original slot from Pragmatic Play features a variety of cats which act as the slot symbols.

Along with the great RTP percentage this slot also features a free spins round, win multipliers and stacked wild symbols. This is a cracking game to play.

9. TORO WILDS REEL (98.03%) BY SYNOT GAMES

Released by Synot Games in 2023, Toro Wilds Reel slot is themed around all things Spanish and has an RTP of 98.03%. Latino music plays in the background whilst you spin the reels on its 5×3 grid with 50 paylines. We would like to remind you that this game is a medium variance slot, so you should see a mixture of smaller and bigger wins.

One of the reasons we have included Toro Wilds Reel on this list is because of its unique theme as well as its features which include a fun bull themed bonus game which gives the opportunity of free spins. One of the downsides to this one is its ack of features, there are no respins or cascading reels etc which is rather disappointing given this is a new slot game.

Features in Toro Wilds Reel:

• Free spins
• Bonus game
• Wild symbols
• Scatter symbols
• Multipliers

Play at: BetFred Casino

10. BLOOD SUCKERS (RTP: 98.00%) BY NETENT

Blood Suckers is the second vampire themed slot to make our list of the top RTP slots. This NetEnt slot has plenty of modern slot features including Scatters, Wilds and Bonus symbols.

Blood Suckers is a low volatility slot but comes highly recommended due to its RTP and the fun it allows players.

Features:

• Free spins
• Bonus game
• Scatter symbols
• Wild symbols
• Autoplay
• Mobile friendly

Play at: Playzee Casino

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

Easily one of the most popular slots from the Rainbow Riches collection, Rainbow Riches Pick N Mix comes with an RTP of 98%. A great feature of this game is that it allows you to choose between one of three bonus features before each spin. The one you pick will featuring during your rounds.

However, to play this slot with the RTP of 98%, you must use the games Big Bet feature. Again, I recommend you to play the game and get used to the setup before you decide to utilise its Big Bet feature and take advantage of the RTP percentage.

EXPLAINING HIGH RTP SLOT GAMES

The Return To Player value of a slot game determines, in theory, the amount you can expect to lose when playing a particular slot.

RTP is not the same as payout. A slots maximum payout determines how much can potentially be won. Whereas the RTP is an indication of how much money you will receive over a long period of time.

You should think of RTP is a House Edge but in reverse. Here’s an example: Ooh Aah Dracula by Barcrest has an incredibly large RTP of 99.00%. The ‘house edge’ will therefore be 1% and the player will get back 99% of their wager.

Still not clear enough? Let’s have a look at a second example: Book of Dead by Play N Go has an RTP of 96.21%. This will give the house an edge of 3.79% over the player. Theoretically, the player will be returned 96.21% of what they wager.

In reality, how much you win when playing online slot machines depends just as much on luck as it does which slot you play. Just because Book of Dead has an RTP of 96.21% does not mean that for every £100 you wager you will win back £96.21. This is just a theoretical assumption. If such certainty existed, slot machines gambling would not be much fun!

RTP is a long term calculation. Furthermore, slot games use Random Number Generator (RNG) technology which ensures they are completely random.

It is useful to remember that the RTP is the opposite of the house edge. If you see a house edge of 4%, it means that the RTP is 96%. This means that the casino is making £4.00 on every £100 wagered in the long run.

THE IMPORTANCE OF A SLOTS RTP

If your plan is to play slots on a regular basis, it is a big advantage to be aware of the RTP of the slots you decide to play. However, there are also other factors you should be aware of too.

For example, a slots volatility level determines how often wins are triggered. A high volatility slot will trigger wins less often in comparison to a slot with low volatility. However, slots with higher volatility levels will trigger larger payouts.

IS THERE A DIFFERENCE BETWEEN RTP AND PAYOUT

Yes, there are several differences between RTP and payout. The main difference being that a slots payout is based on the maximum any individual slot game can payout. For example, the slots with the highest payouts can payout wins of up to 125,000 times the bet. Whereas RTP is based on the average amount which a player can win on a slot over millions of spins.

Payout and RTP are two different aspects of a slot machine and should be considered different from one another.

ADVANTAGES AND DISADVANTAGES OF HIGH RTP SLOTS

Despite being rated among the best slots to play, even slots with high RTP’s still come with advantages and disadvantages.

Advantages of high RTP slot games:

• Can be more rewarding in the long run
• Plenty to choose from
• Widely available

Disadvantages of high RTP slot games:

• Some lack the best features

All casino games have pros and cons, you should consider how much fun you are having as the most important aspect. When playing high RTP slots, you should always take your bankroll into consideration.
