Keeps the scoring program that ranks every slot here, and writes the lists that come straight out of it.
Updated
This page carries figures checked on the date above, and that window has now passed. Studios publish new RTP settings and casinos change their rules: re-check the sources at the foot of the page.
This list sorts by one number only: RTP, the share of all money staked that a slot is designed to pay back over millions of spins. Highest first.
Read every percentage below as a ceiling. It's the top RTP setting the studio publishes for that game. Most studios also sell lower versions, and the casino decides which one you get. Blood Suckers at 98% is only 98% if the casino runs that version. Eleven of these fifteen games list at least one lower setting, and some go below 85%.
And even at 98%, the expected value is negative. The house keeps 2% of everything staked, on average, in the very long run. Your next hundred spins could return much less, or more, and RTP says nothing about which.

The ranking
Every slot we scored, sorted by the highest RTP its provider publishes, at most 3 per provider. Ties go to the higher Spin Score. Spin Score = 40% RTP, 15% max win, 30% free spins round, 15% base game. How we score
The only slot in our 105 with a 98% RTP, and NetEnt rates it low volatility, 2.7 out of 10, with a 45% hit frequency. So far so good. The Spin Score is just 6.4, though, because the rest is thin: a 900x max win, 10 free spins from three scatters, a pick-a-coffin bonus and plain line hits in between. It came out in 2009 and plays like it. NetEnt's note says casinos may run lower settings, so confirm the 98% before you start.

What it is: A 5x3, 25-line vampire slot. Three scatters give 10 free spins, and three bonus symbols on a line open a pick-a-coffin bonus.
Free spins round: 10 free spins from three scatters plus a separate pick-a-coffin bonus game; simple, with one twist each.
Base game: Mostly straight line hits between the scatter and bonus triggers.

At 97.03% it's the only other slot in our data at 97% or above, which gives it a full 10 on our RTP scale. Push Gaming also lists a 94.67% setting, and that gap is big. Up to 15 free spins carry sticky wilds, and collecting bees can switch on Swarm mode with many more of them. A chest pick feature with instant prizes can land in the base game. The highest win Push Gaming has observed is 3,069x, which is modest. Medium-high volatility.

96.9%, and Big Time Gaming publishes just that one figure. On any spin, adjacent reels can clone into 3 to 6 identical reels on up to 117,649 ways, and playin.com puts the max win at 77,800x. The bonus is the weak spot in our scoring: the studio doesn't publish how the free spins work, so the editors scored it a plain 5 rather than guess. Playin.com rates volatility a full 10 out of 10, so this is not a calm high RTP game. No bonus buy.

The best game on this list if you weigh everything, with a Spin Score of 8.5 at 96.83%. It ties Gemix on RTP and goes ahead on score. An 8x8 cascading cluster grid where Jam Jar wilds move in free spins and their multipliers grow with every win they join, while the Rainbow feature drops giant fruits in the base game. Push Gaming's highest observed win is 19,998.5x. It also lists a 94.25% version, so check the loading screen.

Same 96.83% as Jammin' Jars, ranked just behind on Spin Score. There are no free spins at all, which is why the bonus gets a 4. The base game does everything instead: cascades on a 7x7 grid fill a crystal charge meter that fires Chain Lightning, Light Beam, Crystal Warp or Nova Blast. Medium volatility and a 4,513.5x max win. Play'n GO's page lists no RTP, and Bigwinboard shows five settings reaching down to 84.9%. That's a big spread.

96.82% at the top, but SlotCatalog lists five lower settings, the lowest at 90.07%. It has the lowest base game score in our whole data set, a 2, because most spins do nothing until three scatters land. Then 12 free spins make every wild sticky and double all wins. NetEnt rates volatility 9.9 out of 10. Its stats box shows an 8,600x max payout while SlotCatalog quotes 12,000x in the bonus; we use NetEnt's figure.

96.8%, and the stronger game of the two Dead or Alive slots, with a Spin Score of 8.4. You choose between three free spins modes, Old Saloon, High Noon Saloon or Train Heist, built on sticky wilds and multipliers up to 16x. The base game is plain 9-line play and scores 3. NetEnt's Train Heist text says wins can reach 100,000x, though the stats box on the same page shows 1,600x. Expect very long quiet spells.

Ties Big Bass Bonanza on 96.71% and ranks first of the pair on Spin Score, 7.4 to 6.9. The difference is the bonus. Up to five random modifiers can be added before free spins start, and retriggers bring 2x, 3x and 10x multipliers on fish collections. Max win is 5,000x. The base game is plain 10-line play and scores 3. Pragmatic lets the casino pick 96.71%, 95.67% or 94.6%, so look in the info screen.

96.71% top RTP and the same fishing loop that started the series: the fisherman wild collects every fish money symbol on screen during free spins, and every fourth wild retriggers with 2x, 3x then 10x multipliers. The low 2,100x max win, per Bigwinboard, pulls the score down to 6.9. Pragmatic lists a 95.67% setting too. Full details in our Big Bass Bonanza guide.

96.7% with a 94.06% alternative, and an 8.4 Spin Score, so this is one of the best all-round games here. Mystery stacks on reels 2 and 4 nudge down and raise a win multiplier in free spins, and Golden Sharks start the Razor Reveal instant prize feature in the base game.

96.59%, and the source we used listed only that default, so we can't tell you what lower settings exist. Assume they do; Play'n GO publishes several for its games and the casino picks. No classic free spins here: filling the portal adds Special Wilds and grid effects, which the editors scored a 6. Cascades and a x2 Rich Wilde wild give the base game an 8. Max win is only 2,000x.

96.55%, with 95.53% and 94.55% versions. Three or more scatters give a choice of two bonuses: sticky wilds with 2x or 3x multipliers, or more spins with up to six raining wilds per spin. That choice is why it scores 8 on the bonus. Wilds on reels 2 to 5 carry multipliers in the base game too, but there are no tumbles.

96.48%, and one of only two medium volatility games on this list. Eight or more matching symbols anywhere pay and cascade away, and bomb symbols either add to or multiply a win multiplier applied at the end. The free spins are the same idea with more bombs, so the bonus scores 6. Max win 5,000x. Hacksaw lists four settings down to 88.14%.

Demo buttons open the free-play version on the game studio’s own site: no deposit, no account. We are not paid for them. How we make money
How this list is made
Simple sort. We take the highest RTP each studio publishes for each of our 105 slots, rank them from top to bottom, break ties on Spin Score, and stop each studio at three games. The Spin Score is shown on every card so you can see which high RTP games are also good games. It's explained on how we score slots.
The RTP here is the top setting, not a promise
Studios build the same game at several RTPs and sell the choice to casinos. Of our 105 slots, 65 list at least one lower setting, and 24 have one below 90%. On this list alone, Gemix, Legacy of Dead and Dead or Alive each have five or six settings listed in our sources.
So the 96.58% you read here could be 84.55% at the casino you open. Not always. Often enough that you should check. Open the game, find the info or paytable screen, and look for the line that states the theoretical return. Some studios also print it on the loading screen. If it's lower than the figure on the card, you're on a lower setting.
Less than people hope, and more than nothing. Over a very large number of spins, 1,000 units staked in total on a 98% game is expected to cost 20 units. At 96.46%, the bottom of this list, it's 35.40. At an 84.55% setting it's 154.50.
That last figure is the real story. The difference between the top two slots here is tiny next to the difference between a game's best and worst setting.
None of this tells you what one session returns. High volatility games like Dead or Alive can swing a long way from their RTP for thousands of spins.
What the top of the list has in common
Not much, honestly. Blood Suckers is a 2009 low volatility game with a 900x max win. Queen of Riches Megaways, two places down, is rated 10 out of 10 for volatility with a 77,800x max win. High RTP and calm play are not the same thing, and this list proves it: 11 of the 15 are high or very high volatility.
Older NetEnt and Play'n GO titles show up a lot, and three Push Gaming games make it. Jammin' Jars, Dead or Alive 2 and Razor Shark score above 8 overall, and Hellcatraz sits right on it.
What's missing, and why
The three-per-studio cap cut a few. NetEnt's Finn and the Swirly Spin (96.62%) and Mega Fortune (96.6%) would have made it, and so would Push Gaming's Razor Returns at 96.55%, our top scorer overall. You'll find it on the best online slots list.
At the other end, ten of our slots publish less than 96%, including the original Gonzo's Quest at 95.97%, and three sit at 94%.
Frequently asked questions
Which slot has the highest RTP?
In our data, Blood Suckers from NetEnt, at 98% in its top setting. A casino may run a lower one, so check the game's info screen. Outside the 105 games we scored there may be others; we only rank what we've sourced.
Does a higher RTP mean I will win more?
Not in any session you'll play. RTP is an average over millions of spins, and every slot still has a negative expected value. A higher RTP means you lose a bit less on average over a very long time. That's all.
How do I check the RTP at my casino?
Open the game and look in the info, help or paytable screen for the theoretical RTP. Compare it with the figure on our card. If the casino's number is lower, it's running a lower setting of the same game.
Is a 96% RTP good for a slot?
It's typical. 93 of our 105 slots sit between 96% and 97% in their top setting. Below 96% is on the low side, and our scale gives anything at 94% or less the minimum score.
Do bonus buys have a different RTP?
Often, yes, and some studios publish it. SlotCatalog gives Hellcatraz 96.88% with the bonus buy against 96.46% in Mixed Mode. Fire in the Hole 3 alone lists buy options from 60x to 7,000x the stake, so the swing on a single round is huge.
