Top 10 High Payout Slots – Updated for 2024

High Payout Slots

Every slot game has an official Return to Player (RTP) percentage. This figure shows how much a slot machine is expected to pay back its players.

The closer an RTP is to 100%, the more money you’re expected to win. So, if a slot has an RTP of 97%, you are likely to win €97 for every €100 you put in.

In online casinos in the UK, the best payout slots, or high payout slots, are those with the highest RTP percentages.

To save you the time of searching for the best high payout slots available today, we’ve compiled a list of the top 10 high payout online slots for 2024 you can try out right away.

We’ll also go through everything else you need to know about online slots: where to find them, what to look for when picking a game, and how to pick the best ones.

Top 10 High Payout Online Slots

Here’s our list of the top 10 high payout online slots, along with a summary of what to expect from each of these slot games.

#1. Jackpot Jester 50,000

Jackpot Jester 50,000 – High Payout Slots

At the top of the list for the highest payout is Jackpot Jester 50,000, a NextGen production that has a 95.08% RTP. You can play Jackpot Jester at All British Casino and Race Casino.

The best thing about this classical fruity Jackpot Jester is that it’s effortless to play. You begin the game on the bottom set of reels, where you can either bet 10 or 20 coins. If you win by betting 20, your winnings will be transferred to the upper set of reels, where you can play the so-called Super Game. In the Super Game, you have the chance to win a 50,000 coins jackpot.

Although this feature isn’t unique to Jackpot Jester, no other slot game will bring you such good returns. The visuals are also very well-executed: expand the game to cover the whole screen and you’ll feel as if you’re playing in a real, brick-and-mortar casino.

#2. Book of 99

Book of 99 - high payout

99 by name and 99 by nature  – ‘Book of 99’, developed by Relax Gaming, brings an innovative twist to the ‘Book of’ slot genre. The game stands out with a unique 99RTP and an ancient Greek theme that adds a layer of intrigue.

The game provides two paths to trigger free spins: collect 99 books during gameplay or land on a 3-symbol trigger. The bonus round introduces an interesting mechanic where a warrior character expands to fill the reel, potentially increasing winnings significantly.

Most importantly, though, this game has a 99.00% RTP. Give it a go at 21prive casino.

#3. White Rabbit Megaways

White Rabbit Megaways - High Payout

White Rabbit Megaways from legendary slot providers Big Time Gaming offers an incredible 250,000 paylines as the board randomly expands to reveal up to twelve symbols on each reel. You can play it at Casumo Casino.

Highlights of this Alice in Wonderland themed slot include Big Time Gaming’s Feature Drop ™ which allows you to buy free spins – at a reduced price if you get BTG symbols. And we’re delighted to see the caterpillar making an appearance who will blow smoke rings onto the reels which will double or triple your wins.

With a 97.07% RTP, White Rabbit is the highest payout BGT slot currently available. 

#4. Joker 10000 Deluxe

Joker 10000 Deluxe - High Payout

With its traditional fruit machine theme and no-nonsense gameplay, Joker 10000 Deluxe by Betdigital is a refreshing standout in the realm of online slots. Released in 2016, the slot game sports a classic 3-reel design with 5 paylines and an autoplay feature for those who prefer letting the machine do the spinning.

But what truly sets Joker 10000 Deluxe apart is its impressive RTP of 97%, placing it well above the average for online slots. This means that for every £100 wagered, players could expect to get back £97 in the long run, making it an appealing choice for those seeking a higher return on their bets.

However, don’t expect free spins, bonus rounds, or progressive jackpots here. Joker 10000 Deluxe is all about straightforward, old-school slot gaming. It might not have all the bells and whistles of some newer slots, but its higher-than-average RTP and straightforward gameplay make it a worthwhile spin

#5. Bloodsuckers 2

Bloodsuckers 2

Bloodsuckers 2 is NetEnt’s sequel to the very popular Bloodsuckers slot and delivers twice as much vampiric goodness thanks to its incredibly generous 96.95% RTP – highly unusual for a mainstream NetEnt slot.

There is a fairly standard 5 reel, 25 payline layout with the distinction between this and the prequel being the succulent (!) 3D style graphics which lend the game a scarily immersive vibe.  Spins start from 0.25 a spin up to 250 if you fancy being a bit of a high roller.

#7. Nemo’s Voyage

Nemo’s Voyage – High Payout Slots

Nemo’s Voyage is a 5 reel, 40 pay line slot made by WMS. Each spin of the reels moves it down the depth meter and right within the pressure gauge.

As you reach each bonus section, the symbols on the reels will be joined by Multiplier Wilds, Pressurised Wilds, or Clumped Wilds, or you’ll enjoy the sight of 1 to 3 reels turning Completely Wild.

The Increase Pressure and Decrease Pressure icons control the submarine’s movement towards the surface and down to the ocean’s floor. You want the submarine to sink as low as possible because as the Nautilus descends, the RTP increases. Add to this the Scatters feature being able to trigger Free Spins round with Persisting Wilds and it’s clear this is a game you could be playing for a while. And you’ll love doing it, thanks to its high RTP of 99.00%.

You can play Nemo’s Voyage at Play Ojo casino.

#8. Ooh Aah Dracula

Ooh Aah Dracula – High Payout Slots

If you like vampires or dark-themed games, this Barcrest video slot game is just for you. Ooh Aah Dracula has a slightly crazy Dracula theme, with creepy symbols, flickering candles, dripping blood, and scary music. Want to try it out? Head over to Yeti Casino now!

On top of these great graphics, the game allows you to pick 5 spins at £20 or £30 and trigger one of two special graveyard bonuses. It also offers Free Spins bonuses that come with randomly assigned Wild symbols and several rounds of decision making, prompting you to collect what you won or give it another try (Stake It Or Leave It Free Spins).

An interesting addition is the Best Strategy Indicator, which reveals what is statistically the best decision. It evaluates the average win based on the value of Wild symbols but does not guarantee the outcome.

#9. 1429 Uncharted Seas

1429 Uncharted Seas – High Payout Slots

The 1429 Uncharted Seas slot has 5 reels, 25 pay lines, and two exciting bonus features: Expanding Wilds and a Free Spins Bonus. It’s available at Betfred Casino.

The sun, moon, and stars give you the most basic payouts, whereas the sea creatures pay you up to 10 times your wager. The mermaid brings the biggest money – if you can line up five mermaids on a pay line, it’ll multiply your bet by a delicious 50 times.

Compasses, on the other hand, reward you with free spins. Line up three compasses and you’ll get 10 extra free spins. With four compasses, you can earn 20 free spins and with five compasses, 50 bonus spins.

#10. Legacy of Dead

Legacy of Dead is a high volatility Play N Go slot with a well above average RTP of 96.6%. There are ten winlines and a maximum win of 5000x your bet.

What Are Slot Payout Percentages?

A slot payout percentage is the same thing as a Return to Player (RTP) percentage. Both represent the estimated, average percentage that is expected to be returned to a player as a winning.

Now, people often think that this means a slot payout percentage indicates how often a player is likely to win. That’s not the case, though. A slot payout percentage or RTP is only an average estimation. There’s no way anyone can know in advance whether they’ll win or lose.

For instance, two games can both have an RTP of 97%, however, one might pay out more frequently at lower amounts while the other less frequently, but at a higher rate.

But, how is RTP calculated?

It’s pretty straightforward: you just divide the total amount returned to players by the total amount they’ve put in the slot. So, if a player gambles £1,000 and gets £960 back, the RTP would be 0,96 or 96%.

What To Look For in Online Slots

Yes, a high payout is important. But there are other factors you need to take into consideration when choosing what slots to play.

Here’s what to look for in online slots to increase your likelihood of winning in the long term:

1. High RTP

Normally, slot machines have an RTP of 94%. So, avoid playing slots with a lower RTP than that percentage.

2. Free Spins

Free spins are a great way to earn a stake-free profit. They often also come with additional features, such as extra wilds, sticky wilds, cascading reels, or multipliers.

3. High Hit Frequency

A slot hit frequency or hit rate tells you how often you can expect to land on a winning combo when playing. The higher the frequency, the better.

But be careful, though – don’t base your decision on hit frequency only. A slot can have a high hit rate but end up paying you back a sum that’s smaller than what you put at stake.

4. Volatility

Volatility, or variance, is the frequency with which you can expect a slot to pay out, and how big your wins will be. A high variance slot requires you to play a lot before a win arrives. When you do win, however, it’ll be a big sum. A low variance slot means the opposite: you’ll win a lot but at low amounts. Choose accordingly, depending on how much time and cash you have in hand.

High Payout Online Slots FAQ

#1. What online slot has the highest RTP?

The online slot with the highest payout is Jackpot Jester 50,000, with a 99.9% RTP.

#2. How are slot payouts calculated?

Slot payouts are calculated through the below formula:

RTP = Total Amount Returned to Players / Total Amount Gambled by Players

#3. Why do some slots have different payouts?

Payouts differ from slot to slot depending on a variety of game features such as the number of free spins, jackpots, reels, pay lines, bet sizes, and more.

#4. Can online UK casinos change the payout rate?

Changing the payout rate of slots is not typical for casinos. Online casinos in the UK are regulated by the UK Gambling Commission, which ensures that the casinos won’t tamper with their games.

#5. How can you withdraw money from online UK casinos?

The process of withdrawing money from an online UK casino largely depends on the payment method and casino you’ve chosen. This being said, some steps remain the same regardless of your payment solution.

First, you’ll have to go to the cashier’s section. This section is usually located in the same place where you’ve deposited your money initially.

There you can choose your withdrawal method and fill out any required financial and personal details. And you’re done!
