LIST OF THE 10 BEST RTP SLOT GAMES IN 2026 REVIEWED
Without further ado, these are the highest RTP slots at online casinos in 2026:
1. UGGA BUGGA BY PLAYTECH (RTP: 99.07%)
Released by Playtech in 2006, Ugga Bugga has stood the test of time, although it is somewhat unfortunate that we do not see any modern slots released with such a high RTP.
There aren’t any other slots that we can think of that have this feature. The maximum possible payout of 1,000x, whilst fairly low by todays standards, was one of the highest available back when Ugga Bugga was first released.
- Slot Game: Ugga Bugga
- Developer: Playtech
- RTP: 96.08%

- Bonus Features: Bonus Game, Scatter Symbols, Free Spins, Mobile Friendly
Play at: MrQ Casino
2. BOOK OF 99 BY RELAX GAMING (RTP: 99.00%)
With respins, retriggers and, of course, an immensely high return to player percentage, Book of 99 is an exceptional slot game with plenty of features and high paying symbols.
Book of 99 has a max payout potential of 5,000x your stake as well as expanding wild symbols and respins. We recommend playing at Casumo Casino casino where you can help yourself to both free spins and a matched deposit bonus. In addition, Book of 99 is a rather rare slot game, but it is available to be played at Dream Vegas.

3. OOH AAH DRACULA BY BARCREST (RTP: 99.00%)
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! The theme is a lot of fun and the soundtrack is great. Stacked wild symbols are appealing too as they make entering the bonus game much easier.
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.
- Slot Game: Ooh Aah Dracula
- Developer: Barcrest
- RTP: 99.00% (Big Bet Mode)
- Maximum Payout/Multiplier: 457x

- 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%)
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.
Mega Joker also attracts players thanks to its progressive jackpot. The main feature of Mega Joker is its jackpot and that is the number one reason for playing.

5. JACKPOT 6000 BY NETENT (RTP: 98.86%)
You will find traditional slot symbols such as the lemon, a cheery and of course the joker. However, thanks to its RTP, when you do hit a win, you should expect it to be a big one! The main reason players like to play this game is due to its progressive jackpot.
- Slot Game: Jackpot 6000
- Developer: NetEnt
- RTP: 98.86% (Big Bet Mode)
- Maximum Payout/Multiplier: 6,000x

6. DR JEKYLL GOES WILD BY SCIENTIFIC GAMES (RTP: 98.20%)
Certainly one of the oldest slots in this 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 2026. 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.

- Developer: Scientific Games
- RTP: 98.20% (Big Bet Mode)
- Maximum Payout/Multiplier: 500x

7. MARCHING LEGIONS BY RELAX GAMING (RTP: 98.12%)
A fun and rather sophisticated Roman themed slot, Marching Legions was developed by Relax Gaming 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.
- Slot Game: Marching Legions
- Developer: Relax Gaming
- RTP: 98.12%
- Maximum Payout/Multiplier: 10,000x

A relatively unknown slot which is difficult to find, Test Your Strength is a gem of a slot machine with both a high RTP of 98.05% and high a maximum multiplier of 71,785x. For example, if you play Test Your Strength at Dream Vegas Casino, you will be able to play with the max RTP as it is one of the highest RTP online casinos.

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%.
- Starburst XXXtreme by NetEnt: A sequel to the most popular slot of all time it is played on 5 reels and 3 rows with nine paylines. There is plenty more fun to be had in this one though as expanding wilds and random multipliers are available from just 10p per spin. The wilds alone can combine to create multipliers of up to 450x. Biggest wins go all the way up to 200,000 x per spin.
- Razor Returns by Push Gaming: One of many fishing themed slots, Razor Returns is a simple to play slot played on a 5×5 grid with 40 paylines. Features are aplenty and include Mystery symbols, Nudge and Reveal symbols and Push Bet. Multipliers come into play in both the base game and free spins round and the high RTP rate of 96.55% is helpful. All of these can lead to 100,000 x max bet wins per spin.
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.
