Mega Joker – 99% RTP
Mega Joker from NetEnt is based heavily on traditional land-based slot machines, with a simple 3×3 reel layout and just one active payline. The minimum bet is high, but this is one of the highest RTP slots in the UK, with a rate of 99%.
It’s important to note that although the RTP rate is high, so is the volatility. That means that it’s quite possible to go several spins without a win, so manage your bet sizes accordingly.
Book of 99 – 99% RTP
Like other “Book of” slots, this game offers a free spins bonus round where one of the symbols will be chosen at random to expand and fill the reel whenever it lands. Relax Gaming was inspired by the legendary tale of Homer’s Odyssey to create this slot.
The maximum RTP rate is 99%, putting it well above the average for online slots. However, the volatility is high, which allows the game to offer a big maximum win worth up to 12,075x your stake.
Jackpot 6000 – 98.9% RTP
Jackpot 6000 is a classic online slot that is inspired by the popular traditional fruit machine Jackpot 2000. NetEnt created the online version to give players access to a game that offers a generous maximum RTP rate of 98.9%.
The simple 3×3 layout makes it very easy to play, but there are a few different special features to help you hit the top jackpot, including Joker Wilds, Supermeter mode and the Mystery Win bonus game.
Marching Legions – 98.12% RTP
Join the Roman army for Relax Gaming’s Marching Legions. This slot offers 243 ways to win and a maximum RTP rate of 98.12%. The high volatility means the game can also provide a big maximum win worth up to 10,000x your bet.
The bonus features in Marching Legions make it worth playing, with stacked legion symbols nudging into view and triggering respins. There are also free spins if you collect enough stacks.
Money Vaults – 98.07% RTP
SYNOT invites players to open the Money Vaults in this classic online slot. As you spin the reels, you’ll be dazzled by precious gems and have a chance to win up to 4,000x your bet.
The game has an RTP rate that goes up to 98.07%, which is much higher than the average for online slot games (96%). The medium volatility means the payout frequency and sizes are average, so gaps between winning spins aren’t as large.
Madame Mystique Megaways – 98.03% RTP
The Megaways format has been a massive success since it was first released by Big Time Gaming in 2015, and Pragmatic Play used it to great effect in this slot. Madame Mystique Megaways offers up to 200,704 ways to win on every spin, as well as tumble reels, multipliers and free spins.
The game’s RTP rate is an impressive 98.03% at its highest, and you could win up to 5,000x your wager on a single spin.
The Dog House: No Dog Left Behind – 98.02% RTP
This recent release in the “Dog House” series offers a high RTP rate of up to 98.02%. Although the volatility is high, the RTP rate can help you avoid significant losses when playing over a long period of time.
The Dog House: No Dog Left Behind offers lots of exciting bonus features, including sticky wilds and free spins. Combined with the fun animal theme, there’s a nice maximum win worth up to 10,000x your bet.
Blood Suckers – 98% RTP
This exciting vampire-themed slot from NetEnt has an above-average RTP rate of 98%. While the game has since been updated with a sequel, this original still has a higher RTP rate and is well worth playing.
The game’s main bonus feature lets you open coffins and slay vampires to collect cash prizes. The maximum win of 1,014x your bet is great for a game with a high RTP rate and low volatility.
Money Cart 2 – 98% RTP
This is a sequel to the hugely popular Money Train 2 game. It’s essentially the same game but with the base game removed. The main focus is on the hold and win re-spins bonus. Modifier bonuses during the respins can quickly raise your winning potential.
As you play, you’ll get to enjoy all the exciting bonus features, along with an impressive RTP rate of 98% and a big maximum potential win worth up to 5,000x your stake.
Gates of Heaven – 98% RTP
The Gates of Olympus series is a hugely popular Pragmatic Play franchise that also includes Gates of Heaven. This game stands out as one of the best RTP slots with a rate of 98%, which is combined with lots of great features.
As you spin the reels, the tumble feature, multiplier symbols and free spins can all trigger to help you land the maximum win worth up to 5,000x your stake.

What is RTP?
The Return to Play (RTP) is a calculated percentage of how much you could expect to win back when playing a game over a long period of time. For example, if you bet £100 on a slot with an RTP rate of 96%, you’d expect to win back £96.
The RTP of a game is a good judge of how much it pays back on average, although it’s never an indicator of how much you’ll win back over a standard playing session since all casino games are random. Plus, your actual returns can be much higher or lower based on the game’s volatility and your luck.
Difference Between RTP and House Edge
RTP and house edge are essentially opposites. The house edge is the casino’s advantage over the player and the amount that it will win from you over the long term. On the other hand, the RTP is how much you will win back from the casino.
If there was no house edge, a game would have an RTP rate of 100%. The house edge is the percentage difference between 100% and the RTP. So, a game with an RTP rate of 95% has a house edge of 5%.
Can Casinos Manipulate RTP?
No, casinos can’t change the RTP rate of a game beyond the published value. All licensed online casinos have to publish the accurate RTP rate for each game and make it easy for players to find. Additionally, at regulated casinos, RTPs are verified as fair by independent testing agencies like eCOGRA and iTech Labs.
While casinos can’t change the outcome of games or the RTP rate, they do use different versions of games, which can have different RTP rates. The best paying slots might have different RTP rates between casinos, so always check before you play.
Does RTP Apply to Jackpots and Bonuses?
The RTP applies to fixed jackpots and bonus rounds. Any RTP calculation involves the wins throughout the game, including those that are triggered during special rounds such as free spins or through bonus symbols like multipliers and wilds.
Additionally, if a game has fixed jackpots, these are also included in RTP calculations. However, progressive jackpots aren’t included. Progressive jackpots can increase over time, which would mean the RTP also changes. The extremely small chance of landing a progressive jackpot means it would create a misleading RTP rate calculation.
How RTP is Different to Volatility and Variance
While RTP is an important factor to consider when choosing your game, you’re unlikely to notice major differences between two games with different RTP rates. However, the volatility or variance is much more noticeable. This is a measure of the payout frequency and payout size.
Games with high volatility have lower payout frequencies, but there’s greater potential for larger payouts. Low-volatility games pay out more frequently but in smaller amounts. Two games with identical RTP rates but opposite volatility ratings feel very different to play.
Pros and Cons of High RTP Slots
High RTP isn’t a guarantee of how much you’ll make during your play session. It’s essential to consider the full pros and cons of high RTP slots before you choose your game:
Pros
- Greater chance of returns over longer playing sessions
- Better for small budgets
- A variety of High RTP games to choose from
- In theory, your bankroll will last longer
Cons
- Variance generally has a more significant impact on gameplay
- Maximum win is often lower
- Doesn’t make a big difference over short playing sessions
RTP in Progressive Jackpot Slots
Progressive jackpot slots tend to have lower published RTP rates on average compared to regular online slots. However, the actual RTP rate can be much higher because of the potential for huge jackpot wins.
Because jackpot wins are extremely infrequent, the UK Gambling Commission doesn’t allow them to be included in the RTP calculation. When progressive jackpot RTP is measured, it only measures the base game without the jackpot.
It’s technically possible for the RTP rate of progressive jackpots to rise above 100% if the jackpot prize is high enough. However, the chance of winning a jackpot is extremely slim, and game providers usually balance the base game RTP rate accordingly.
High RTP Slots vs Other Casino Games
When it comes to the vast and diverse world of online casino games, each type offers a different average RTP rate. You can check out the table below to learn more about each one.
| Casino Game | RTP |
|---|---|
| High RTP Slots | 96% |
| Blackjack | 99% |
| Bacarrat | 98.9% |

| American Roulette | 94.7% |
| Poker | Varies greatly |
