3. 1429 Uncharted Seas (Thunderkick): 98.6% RTP

1429 Uncharted Seas from Thunderkick is a 5-reel, 25-payline slot game which can be played from 10p per spin on all devices. With a pirate theme, this beautifully designed slot takes you back to the early years of seafaring exploration. The graphics are unique and look like an old treasure map.

It comes with expanding wilds in the base game. There’s also a Free Spins feature where you can start with up to 50 free spins and retrigger to play with up to 100 in total. With expanding wilds during the free spins, this low variance game is popular as the RTP stands at 98.6%. It also offers wins of 670x stake on each spin or free spin.

4. Marching Legions (Relax Gaming): 98.12% RTP

Powered by Relax Gaming, Marching Legions is a 5-reel slot with 243 ways to win. Based on the Roman legion, this graphically superb title comes with stacks of legionnaire symbols that give you re-spins. The respins continue until the legionnaire stacks shift off the reels. To help you, there’s a Nudge element where partial stacks on 2 or more reels will give you Marching Stacks.

In the Free Spins feature, you begin at ‘Wave 1’. Collect horns to move to the next ‘wave.’ When you do this, the Marching Stacks are 2 reels wide. With 5 levels of waves, you could play with 5 Marching Stacks at once. It offers 10,000x stake max wins and a 98.12% RTP rate.

5. Pearl o’ Plinko—Mermaid Cove (Quickspin): 98.1% RTP

An unconventional slot from Quickspin, Pearl o’ Plinko—Mermaid Cove, doesn’t have a standard grid. It uses the buckets at the bottom of the screen, and each bucket appears as a treasure chest, with its value labelled on it.

The volatility is low, and you are guaranteed a return on every spin—the hit rate is 100%! The features and graphics look fantastic, with animations for different icons ensuring the screen is always busy. The max win is rather low (199x the bet), but the RTP of 98.1% is something you rarely see nowadays.

6. Pearl o’ Plinko – Fire & Bones (Quickspin): 98.1% RTP

Another fun Plinko slot following the Mermaid Cove is Pearl o’ Plinko – Fire & Bones. Although both instalments have a high RTP, it is not always to be expected from Plinko. However, the low volatility seems to be a trend with Quickspin, as well as a guaranteed return on every spin—the hit rate is also 100%

The slot is set on a Caribbean island bay with pirate ships on the sides of the action. The max win is just 243x, but with the RTP and hit rate, you are bound to secure some wins.

7. Madame Mystique Megaways (Pragmatic Play): 98.03% RTP

Madame Mystique Megaways is by Pragmatic Play and comes with 6 reels and up to 200,704 ways to win. Based on a fortune teller, it offers tumbles, but the main attraction is the Free Spins feature. Here, you spin the Wheel of Fortun,e which can reward you with up to 12 free spins and a win multiplier of up to 25x. More free spins can also be won.

With 5,000x bet max wins, the Madame Mystique Megaways RTP is 98%, which is very high. The gameplay is rather simple, but the high RTP rate is definitely appealing.

8. Blood Suckers (NetEnt): 98% RTP

Powered by NetEnt, Blood Suckers is a 5-reel, 25-payline slot title which can be played on all devices from as little as 25p a spin. Released in 2009, this vampire-themed slot has an eerie soundtrack and classic graphics. It offers a hit frequency of 44.9%.

9. Money Cart 2 (Relax Gaming): 98% RTP

Powered by Relax Gaming, Money Cart 2 is a bonus feature version of Money Train 2. Played on a 5×5 grid, there is no base game as it focuses on the Re-Spin feature (triggered every 10 spins on average).

With various special symbols in the Re-Spin feature, you can expand the grid to 6×5 in size. With 5,000x bet max wins, Money Cart 2 boasts an impressive 98% RTP rate as standard.

10. Jokerizer (Yggdrasil Gaming): 98% RTP

Jokerizer is by Yggdrasil Gaming and has 5 reels and 10 paylines. Playable from just 10p per spin on all devices, it’s based on classic fruit machines. There’s an enhanced portrait mode for play on mobile devices.

There’s a Mystery Win when you can win up to 600x your total stake if you land 3 or more Joker symbols. You can opt for the Jokerizer Mode for extra prizes, too.

11. Starmania (NextGen Gaming): 97.87% RTP

Powered by NextGen Gaming, Starmania was released in 2015 and comes with 5 reels and 10 paylines. A win-both-ways slot game, this space-themed adventure can be played on all devices, of course, from just 10p per spin.

It comes with a Free Games feature where up to 20 free spins can be won. More importantly, 30 extra stacked wilds will be added across the 3 central reels. This makes it easier to win the max 1,000x stake payout per spin. More impressive is the RTP, which stands at 97.87%.

12. White Rabbit Megaways (Big Time Gaming): 97.24% RTP

A slot that finds inspiration in Lewis Carroll’s Alice offers reels that expand to 248,832 Megaways. Most importantly, with an RTP of 97.24% and a max win of 17,420x, White Rabbit Megaways is one of our highest-rated slots, winning a score of 5 out of 5.

Another thing that separates this slot from the rest is its superb design and a Free Spins feature with the potential to win 75 free spins in total!

What Is RTP in Slots?

RTP, or Return to Player, is a percentage that shows how much money you can make on a specific slot over time. The percentage is calculated over a time period and a larger number of spins. RTP can help you get an idea of how favourable a particular slot game is in the long run.

Finding RTP Rates

As per requirements set out by the UK Gambling Commission, gaming machines (whether a fruit machine, slot machine or FOBT) are required to clearly display the percentage return-to-play figure (RTP%) or the odds of winning a prize.

The RTP is normally found in the slot’s paytable. Most slots will have an “i” or ‘Paytable’ button or icon where you can find the payouts for individual symbols, information about the bonus features, how winning combinations are created and what the RTP% is.

Other ways include checking the detailed reviews here or calculating it yourself. Here are 3 ways to find a slot’s RTP rate:

How Is RTP in Slots Calculated?

A slot RTP is the Return to Player rate you will get when playing that slot game. It’s also known as the payout percentage for online slots. If an online slot has an RTP of 95%, for example, you will win back 95% of your stakes on average (so £95 for a £100 wager).

If the RTP is 50% and wagered £100, you’d win back £50 on average. The bigger the RTP, the more you’ll win back. In theory, the best-paying online slots are the ones with the highest RTP.

The difference between 100% and the RTP is the house edge or profit an online casino will make. If a slot has a 95% RTP, the online casino will benefit from a 5% house edge or margin.

The higher the RTP, the less the online casino wins on average per spin. This is why players will prefer to play the top RTP slots, as their chances of winning are higher.

To calculate a slot’s Return to Player rate, you need to get the amount returned divided by the total amount staked or wagered. For example:

Total amount returned = £97

Total amount stake = £100

RTP = £97/£100 = 97%

What Is Theoretical RTP?

The RTP does not mean you will get £95 from wagering £100 for a 95% RTP slot game. The theoretical RTP is the Return to Player rate that a particular online slot pays out on average across lots of spins. In summary, theoretical RTP is the guaranteed RTP across millions or billions of spins.

If you take Quickspin, for example, they calculate their RTP rates across a billion spins. If you wager £100 and lose every single time, your RTP will be 0%. For a winning player, the RTP could be 200% or even 5000%.

The RTP set by slot providers is the average of all spins in a cycle of a set number of spins. On average (this being the keyword), the RTP for a particular online slot will be what they showcase in the paytable. To summarise:

RTP is the return a slot will pay out over lots of spins, i.e. 95%

Your RTP rate is based on randomness and may be 0% or over 100%

RTP is calculated over millions or billions of spins

Varying RTP Rates

While most slot providers will advertise the highest RTP% % possible, some providers offer different options to their clients, such as online casinos. For example, Play’n GO have 5 different RTP options for all their slots. If you were to take the popular Legacy of Dead slot, the RTP ranges from 96.58% at the top end of the scale, right down to 84.55%.

Check the online casino you play with prior to playing a particular slot. Sadly, most established and new online casinos will offer lower RTP settings on the whole.

If you are playing at a casino regulated by the Malta Gaming Authority, the RTP for a particular slot game may be lower than in the UK. The MGA requires licensees to abide by a minimum average return to player rate of 85% or higher.

RTP and Payout: What Is the Connection?

You will see the term ‘best payout slots’ mentioned, which can be confusing. It’s all down to how you define payout. You can define payout as:

1. The return to player rate (RTP)
2. How much a slot game pays back per spin
3. How often you win (known as hit frequency rate)

In this section, we take a look at the online slots that payout the most per spin or the best-paying slot games. This can also be referred to as max win per spin, maximum exposure or the highest payout rate.

Contrary to the best RTP rates, big payout slots don’t necessarily offer a high RTP. It also works the other way in that a top RTP rate can mean small max wins per spin.

Our focus here is the maximum win per spin in terms of stake or bet multiplier. This may mean these particular high payout slot games are often excluded from wagering requirements for a casino bonus, including no wager free spins offers.

Best Payout Slots

Here are the 5 best-paying slots, jackpot ones excluded, that offer the best payouts per spin or the slots that payout the most on every spin. Each of them can pay over 100,000x bet on a single spin.

Tombstone RIP (Nolimit City)

Created by Nolimit City, Tombstone RIP is the most brutal slot ever made (to date). With 5 reels and 108 paylines initially, this Wild West massacre features amputations, hangings and murder. It comes with xNudge Wilds, Reel Split Wilds, xSplit Wilds, increased ways to win and 2 free spins features.

The Boothill free spins have cowboy multipliers up to 999x, but there’s a 9.08% hit frequency rate, meaning wins will be few and far between. That said, these notorious outlaws can deliver payouts of up to 300,000x bet wins per spin. The RTP is 96.08%, and the volatility is classified as insane.

Starburst XXXtreme (NetEnt)

Powered by NetEnt, Starburst XXXtreme is their sequel to the most popular slot game of all time (Starburst). With 5 reels, 9 paylines and an outer space theme, it is playable from 10p a spin and has a 96.26% RTP rate. Expect a win every 5 spins.

Available on all devices, it comes with Starburst Wilds, which lock in place with re-spins to follow. These wilds come with multipliers up to 150x, which can combine up to 450x (for 3 of them). This can lead to 200,000x max bet wins per spin.

Peking Luck (Pragmatic Play)

Powered by Pragmatic Play, the 5-reel, 25-payline Peking Luck has a Chinese luck theme. It has a high 96.5% RTP rate. Very volatile, it comes with a high-value wild symbol, I, which pays 400x stake for 5 in combination. If a wild is part of a win, your payout is subject to a 2x multiplier.

Like a lot of other high payout slots, it’s all about the Free Spins feature. You pick from fans to win up to 38 free spins. Then, pick from 6 dragons to reveal a multiplier up to 18x. Unlimited extra free spins can be won, but the potential 18x multiplier can give you wins of 180,000x the bet per free spin. To win this, you need a screen full of wilds with an 18x multiplier.

Money Train 4 (Relax Gaming)

The last in the Money Train series by Relax Gaming, Money Train 4 is the bandits’ last ride on the rails. Played on a 6×6 grid with Scatter Pays, it benefits from random respins with multipliers in the base game. It’s playable from just 10p per spin across all devices.

The RTP is up to 96.1%. The focus is the Money Cart Bonus feature, which comes with a new Arms Dealer bandit, other new special symbols and even bigger payouts. Money Train 4 can deliver 150,000x max bet wins

San Quentin (Nolimit City)

Powered by Nolimit City and with 5 reels and 243 ways to win, San Quentin is a prison-themed slot. Using their xWays mechanic, the RTP is 96.03%. There are Enhancer Cells that can reveal Razor Split symbols for up to over 13 million ways to win. xWays symbols display 4-high stacked symbols.

There’s also a Split Wild feature, which gives you up to 46,656 ways to win. The main attraction is the Lockdown Spins feature, which comes with Jumping Wilds. Moving about on each free spin, they can combine with Razor Split enhancers to give you 512x multipliers. This can lead to 150,000x bet wins on each free spin.

RTP and Variance: Why It's Important to Understand the Difference

Your RTP % is connected to a slot’s variance or volatility. If all payouts (RTP) from a slot are distributed evenly in terms of small and medium-size wins, the slot will be a low variance slot. If a slot pays the majority of the RTP in bigger wins, the slot is a high variance slot.

Hit frequency also plays a part. Some slots will have a hit frequency of 10% meaning 1 in 10 spins will result in a winning combination. A slot game with a 40% hit rate means 4 in 10 spins will give you a win. The higher the hit frequency, the more likely you are to win.

Whilst you may be tempted to play slots with high hit frequency, 1 win from a slot can pay a lot more than 10 wins from another slot game.

• Low variance slots: Many high RTP slots are actually low variance. This is because the slot provider will want to limit the risk and return paid out to players. It doesn’t mean these slots can provide big wins, though.
• High variance slots: Most of the wins will come in the bonus features, which may require 100s or 1,000s of spins to trigger. This is because the wins in these features can be very high, i.e. 50,000x your stake per spin.

RTP in Jackpot Slots

When you play a progressive jackpot slot, a portion of the RTP is reserved for the jackpots. This is why the RTP rate for a jackpot slot is typically lower than for an online slot with no jackpots.

In order to offer a progressive jackpot, part of what is wagered on the jackpot slot goes into the progressive jackpot pool or fund. That is then won by the lucky player when the jackpot is hit. If you take NetEnt’s Mega Fortune jackpot slot, it has an RTP of 96.5% overall. The RTP is distributed as follows:

Base game	62.8%
Free Spins	16.8%
Bonus Game	9.3%
Jackpots	7.6%

This means that 7.6% of what is wagered on the Mega Fortune slot goes towards the progressive jackpots you can win. Without the progressive jackpot element, the RTP is 89%. If you compare this to another of NetEnt’s slots, Starburst, which has an RTP of 96.09%, there is a difference of 7.09%, which is quite significant considering the chances of winning the progressive jackpots are pretty remote.

Another example would be IGT’s Cleopatra slot. There’s the standard version and the jackpot version, MegaJackpots Cleopatra. The slots offer exactly the same bonus features, but just the jackpots separate them. Here’s how the RTP varies from one version to another:

Cleopatra	95.02% RTP
MegaJackpots Cleopatra	88.98% RTP (without progressive jackpot)
Difference	6.04% RTP

If you look at the most popular jackpot slots, here’s their RTP with and without the progressive jackpot element:

Slot	RTP with Jackpot	RTP without Jackpot
Mega Fortune (NetEnt)	96.6%	89%
Hall of Gods (NetEnt)	95.7%	88.7%
Mega Moolah (Games Global)	93.42%	88.12%
Jackpot Giant (Playtech)	94.22%	91.24%
Age of the Gods (Playtech)	95.02%	94.03%

RTP Slots and Casino Bonuses

Most slot sites offer bonuses to new and existing players. This is an incentive to get players to sign up and deposit or to keep on playing. Whilst good UK casino bonuses are welcome, they come with wagering requirements.

Playing high RTP slots, in theory, makes it easier for players to clear wagering requirements, allowing them to cash out the bonus. As a result, online casinos don’t allow wagering on certain games for their slots’ welcome bonus. These tend to be slots with the top RTP rates. Please check the casino bonus terms and conditions prior to playing a high RTP slot for a bonus offer. Note that you won’t come across really high RTP slots with new no deposit bonuses.

RTP in Land-Based Slots

If you’re wondering whether playing slots at a land-based casino is more lucrative, think again. In Nevada (home to Las Vegas casinos, for example), the minimum RTP must be at least 75%, whilst it’s at least 83% in New Jersey. Online, the average RTP is around the 95.5% mark.

If you take Novomatic and WMS as an example, many of their slot games originate from the land-based environment. This is why their RTP rates tend to be around the 95% mark. Newer releases, though, are 96% or over on average.
