Top 10 Slots With The Highest RTP In 2026
If you find a bonus eligible on one of the following slots, you may have a great chance of winning:
No. 10 – Pragmatic Play’s, The Catfather
Return To Player – 98.1%
One of the remarkable features of The Catfather is clearly its RTP, which stands at a fantastic 98.1%.
But this RTP is made even more remarkable by the fact that The Catfather also has a low volatility.
A high RTP and a low volatility is one way to account for short-term and long-term rewards – an ideal combination when playing with a casino bonus.
No. 9 – Relax Gaming’s, Marching Legions
Return To Player – 98.12%
Unlike The Catfather, Relax Gaming’s “Marching Legions” has a high volatility and a high RTP. This makes the game incredibly exciting.
However, when playing with a casino bonus you might find you burn through your bonus balance quickly. Hopefully you get a bit of luck because the soundtrack is 🔥.
No. 8 – Scientific Games’s, Jekyll Goes Wild
Return To Player – 98.2%
What many players don’t understand is that for a lot of these high RTP slots, the RTP is only ‘high’ when you make huge bets.
It is therefore essential that when you play Jekyll Goes Wild you play it with a casino bonus with a high max bet size – high roller casino bonuses are ideal for this.
No. 7 – Thunderkick’s, 1429 Uncharted Seas
Return To Player – 98.6%
Coming in at #7 is Thunderkick’s “1429 Uncharted Seas” with an RTP of 98.6%. We’re big fans of this slot game!
The slot has conspicuously great artwork, but our favorite aspect of the game is actually its in-game free spins bonus round, which can reward you with up to 50 free spins!
No. 6 – NetEnt’s, Jackpot 6000
Return To Player – 98.86%
NetEnt’s “Jackpot 6000” is not the flashiest of titles. This slot is NetEnt’s take on a classic slot game and therefore draws on the allure of nostalgia rather than innovation.
But, if you are playing pragmatically, it may be an ideal slot to play with a casino bonus. Jackpot 6000 has a massive RTP and low volatility, similar to The Catfather.
No. 5 – Barcrest’s, Ooh Aah Dracula
Return To Player – 99%
Ooh Aah Dracula promises a high RTP, but is it an ideal slot to play with a casino bonus? Probably not.
For one, you need to max the bet size to increase the RTP to 99%. For another, the volatility is particularly high, which means you can lose your bonus funds pretty quick if you’re unlucky.
No. 4 – Relax Gaming’s, Book of 99
Return To Player – 99%
“Book of 99” by Relax Gaming is named after its RTP. Yet to try and give the slot a bit more of an edge, Relax Gaming gave it the tried and tested theme of treasure hunting.
To be frank, Book of 99 isn’t the most coherently thought out slot, but it does provide a great RTP and a free spins bonus round that gives you the chance to win 5,000 times your stake.
No. 3 – NetEnt’s, Mega Joker
Return To Player – 99%
If you have spent time looking through articles about high RTP slots, you’ll probably have come across Mega Joker.
Yes, it is true that Mega Joker has a huge RTP of 99%. But did you know that the RTP is variable depending on the size of your bet?
Mega Joker i=only has a 99% RTP if you max your bet, so be sure to only play it with a casino bonus with a high max bet size.
No. 2 – Playtech’s, Ugga Bugga
Return To Player – 99.07%
Ugga Bugga is a slot game that deserves a ⭐!
Our advice is to claim any casino bonus available on this slot (so long as the T&Cs are fair, of course).
The RTP is huge, the volatility is low – the slot will therefore give you a great chance of keeping your bonus balance positive and a great chance of ultimately making a profit.
No. 1 – Playtech’s, Goblin’s Cave
Return To Player – 99.32%
And the slot that currently has the highest RTP is (*drum roll*)… Goblin’s Cave, by Playtech!
Yet – and it’s a big YET – it only has the highest RTP when you are playing with the maximum bet.
Again, this may mean the slot is ideal for high rollers. Especially because the difference in RTP is pretty large, with low value bets reducing the RTP to around 94.5%.
