Of the 39 slots we checked against studio pages, these ten rank highest, and the table lists every figure with its source. The RTP column is the studio’s published value, read on 24 October 2026.

What does each of the highest RTP slots offer?
Figures below are studio values unless a sentence says otherwise. NetEnt’s own pages show 96.62 % for Finn and the Swirly Spin and 96.96 % for Reel Rush. Maximum payouts are NetEnt’s own field, and databases give higher numbers for several games, such as 2,000x for Mega Joker against NetEnt’s 200x.
1. Mega Joker, 99.00 % RTP
Mega Joker, released on 1 October 2008, is a 3×3 NetEnt slot with 5 fixed paylines, mystery wins, a progressive jackpot and a Supermeter mode that takes the wins from the basic game. NetEnt’s page shows one RTP, 99.00 %, and no figure per mode. Hit frequency is 17 %, the volatility index 9.9 and the maximum payout in the basic field 200x.
Bets on the studio page run from 1 to 10 EUR. A third-party review claims 76.9 % at the lowest bet level, which NetEnt does not confirm, so the studio does not tell you whether 99 % applies at every bet level. It suits players who want a short, old-school game and are prepared to learn the Supermeter rules before staking real money.
2. Jackpot 6000, up to 98.9 % RTP
Jackpot 6000, released on 24 December 2007, is a 3×3 NetEnt slot with 5 paylines, a joker wild, a double-up gamble and a Supermeter mode. NetEnt words the RTP as “potential up to 98.9 %” and lists no base-mode figure, so read 98.9 % as a ceiling. A third-party review puts base mode at 95 %. Hit frequency is only 10 %, the lowest in this ranking, the volatility index is 9.9 and the studio’s maximum payout is 600x.
Bets run from 0.10 to 2.00 EUR. The numbers describe long dry spells and a payback figure that may depend on the mode. It suits experienced players with small stakes who understand a Supermeter and accept the long waits.
3. Blood Suckers, 98.00 % RTP
Blood Suckers, released on 10 November 2009, is a 5×3 NetEnt slot with 25 paylines, wilds, free spins and a pick-and-click vampire bonus. NetEnt states an RTP of 98.00 % with no separate settings. The hit frequency is 45 %, the highest in this ranking, the volatility index is 2.7 and the maximum payout is 900x.
Bets run from 0.25 to 50 EUR. It is the only game in the top three that combines a very high RTP with a low index and a frequent hit rate, which makes it the practical choice for stretching a balance. It suits anyone who wants high payback without the Supermeter rules of the 3×3 classics above it, and who does not need a huge ceiling.
4. Jack Hammer 2: Fishy Business, 97.07 % RTP
Jack Hammer 2: Fishy Business, released on 23 July 2012, is a 5×3 NetEnt slot with 99 paylines, sticky win re-spins and free spins. NetEnt states an RTP of 97.07 %. Hit frequency is 24 %, the volatility index 3.9 and the maximum payout 800x. Bets run from 0.50 to 250 EUR.
Third-party sites quote other ceilings, but we use the studio’s figure. The 99 paylines mean most spins give you several lines in play, and the low index keeps swings moderate. It is the highest-RTP game in this ranking with an index below 4 apart from Blood Suckers, so it suits players who want a payback figure near 97 % with calm sessions and a mid-sized stake.
5. Steam Tower, 97.04 % RTP
Steam Tower, released on 23 February 2015, is a 5×3 NetEnt slot with 15 paylines, stacked wilds, a coin bonus and free spins with a progressive multiplier. NetEnt states an RTP of 97.04 %. Hit frequency is 33 %, the volatility index 5.7 and the maximum payout 1,000x.
Bets run from 0.15 to 150 EUR. One operator listing seen on a secondary database shows 92.01 %, which is not a studio statement but a clear sign that you should check the version at your casino before you assume 97 %. It suits players who want a high payback figure with middle-of-the-range swings and a bonus whose multiplier grows as the free spins go on.
6. Reel Rush, 96.96 % RTP
Reel Rush, released on 24 July 2013, is a 5×5 NetEnt slot whose ways to win grow from 45 up to 3,125 through re-spins, with wild substitution and free spins. NetEnt’s page shows an RTP of 96.96 %. Hit frequency is 28 %, the volatility index 5.9 and the maximum payout 1,000x.
Bets run from 0.50 to 100 EUR. A secondary database notes that RTP ranges have existed since April 2020 but lists no values, so the casino’s info screen is the place to confirm it. It suits players who like a game whose grid grows during play and who accept a medium index.
7. Dead or Alive 2, 96.80 % RTP
Dead or Alive 2, released on 23 April 2019, is a 5×3 NetEnt slot with 9 paylines, sticky wilds, three free spins modes and a feature buy that the studio flags without a price. NetEnt states an RTP of 96.80 %, split into 68.6 % from the main game and 28.2 % from the bonus. Hit frequency is 30 %, the volatility index is the top value of 9.9 and the maximum payout is 1,600x.
Bets run from 0.09 to 9.00 EUR. More than a quarter of the RTP sits in the bonus, so a session that never reaches the bonus returns far less than the headline. It suits patient players with small stakes who want a high RTP and accept a very high index.
8. Big Bass Bonanza, 96.71 % RTP
Big Bass Bonanza is a 5×3 Pragmatic Play slot with 10 fixed paylines and free spins of 10, 15 or 20 rounds, where collected money symbols can reach up to 2,000x per symbol according to the studio. Pragmatic Play’s page shows an RTP of 96.71 %. Slotcatalog.com lists lower settings of 95.67 % and, in two operator listings, 89.5 %, which makes it the clearest example here of a headline RTP that varies by casino.
The same database labels volatility medium-high and gives a maximum win of 2,100x. Pragmatic publishes no hit frequency. It suits players who want a mid-range payback figure from a simple game and who will check the version at their casino.
9. Finn and the Swirly Spin, 96.62 % RTP
Finn and the Swirly Spin, released on 23 November 2017, is a 5×5 NetEnt cluster slot with avalanches, wilds, a free spins key, four free spin modes and random features. NetEnt’s page shows an RTP of 96.62 %, with 50.7 % coming from the main game. Hit frequency is 22 %, the volatility index 4.4 and the maximum payout only 300x, the lowest in this ranking.
Bets run from 0.10 to 200 EUR. It sits at the bottom of the verified ranks, only just above the 96 % that many slots sit around. It suits players who want a payback figure slightly above average with lively features and who do not need a high ceiling.
10. Gemix, RTP unverified
Gemix, released on 1 December 2014, is a 7×7 Play’n GO cluster slot with cascades, Crystal Charge, Super Charge and reel modifiers. Play’n GO does not publish an RTP, and we could not verify one: slotcatalog.com’s header shows 94.78 % while other reviews give 96.83 %. That is why Gemix sits outside the numbered ranking.
The database labels volatility medium and gives a maximum win of 6,025x, though other reviews say 4,513.5x. Play’n GO also ships several RTP versions of its games, so even a verified figure would not apply to every casino. It suits cluster fans who check the RTP in the game’s info screen before they decide, and who do not rely on a number from a list.
What does a 1 % RTP difference cost you?
RTP is the share of your stake a slot returns on average, so every percentage point is one euro lost per hundred staked in expectation. Stake 2,000 EUR over a month on a 98 % game and the expected loss is 40 EUR. On a 97 % game it is 60 EUR, and on a 96 % game 80 EUR. Your real result will land far from those figures, and it can land on either side.
Try your own numbers in the calculator below: enter the stake you expect to turn over and compare two RTP values.
The calculator gives an average over a very large number of spins, not a forecast for your session. Our RTP guide explains the difference.
Can the same slot have a different RTP at another casino?
Yes, for some studios. NetEnt’s pages show a single RTP per game, but secondary databases name other versions for several titles, such as 92.01 % for Steam Tower in one operator listing. Pragmatic Play shows one value, and databases list settings in steps like 96.5, 95.5 and 94.5.
Big Bass Bonanza goes from 96.71 % down to 89.5 % in two operator listings. Play’n GO publishes none, and databases name ladders from about 96.5 % to about 84 %. None of these are confirmed by the studios.
A higher published RTP does not protect you if your casino runs a lower version. Over a very large number of spins, results settle near whichever setting the game uses, as the short walkthrough below shows.
Read the RTP on the game’s info screen at the casino before you play, and do not assume it matches the demo or the figure on a list.
Where can you play high RTP slots for real money?
The casinos below are licensed for your market. A published RTP only helps if the casino runs that version, so check the game’s info screen before you deposit. 18+.
The casinos shown hold licences in regulated markets including the United Kingdom and Ontario and are independently reviewed; whether you can register depends on where you live. We may earn a commission. 18+, please play responsibly.
Playing from the United States? See our social casinos available in the US.
How can you keep play safe?
Play only if you are 18 or over. A high RTP lowers the expected cost of play but never removes it, so budget as if you will lose the stake. Set deposit and time limits first and keep to them.

Frequently asked questions
What is a high RTP for an online slot?
Most studio-published figures in our checks fall between 96 % and 97 %. Anything at 97 % or higher is high, and only Mega Joker, Jackpot 6000, Blood Suckers, Jack Hammer 2 and Steam Tower reach that.
Do high RTP slots guarantee that you will win?
No. RTP is an average over a very large number of spins, and a single session can end far above or below it. A high RTP lowers the expected cost, nothing more.
Which slot has the highest RTP?
Mega Joker, at 99.00 % on NetEnt’s page, with no figure given per mode. Jackpot 6000 follows with “up to 98.9 %” and Blood Suckers with 98.00 %.
Can a casino change the RTP of a slot?
Some studios supply several versions of a game and let the casino choose. The studios we checked publish one figure, so the game’s info screen at your casino is the reliable source.
Where can you find the official RTP of a slot?
On the studio’s game page where it publishes one, and on the game’s info or help screen at the casino. NetEnt and Pragmatic Play publish an RTP; Play’n GO did not on the pages we read.
