Highest RTP Slots: The Best Payout Online Slots Ranked
The highest RTP slots are the online games that, by their published math, return the largest share of wagered money to players over the long run. This guide ranks the best RTP slots you can actually play, lists each one with its provider and volatility, and explains the single most important catch: the same title can be shipped in several return builds, so a high number in a review does not guarantee the version in front of you. For our full library of the USA online slots, start here, then use the sections below to find high RTP slots that match your style.
If you are hunting for the highest paying slots to stretch a bankroll, this guide pairs a verified table with plain talk about what those figures do and do not mean. The genuinely elite games sit near 99 percent, but the number on the screen is only ever as reliable as the build your casino chose to run.
Key Takeaways
- RTP, or return to player, is the long run percentage of stakes a slot is designed to pay back. A 98 percent slot keeps about $2 of every $100 wagered across millions of spins.
- The genuinely elite games sit near 99 percent: Goblin’s Cave, Ugga Bugga, Mega Joker, Book of 99 and Ooh Aah Dracula lead the pack.
- Some headline figures apply only under conditions. Mega Joker and Jackpot 6000 reach their top RTP only at max bet, and hold games like Ugga Bugga assume correct decisions.
- Many modern slots ship in multiple RTP versions. Always open the in-game paytable and check the number your casino actually runs.
- High RTP lowers the house edge, but it is not hit frequency and not low risk. A 99 percent slot can still empty a session through variance.
What RTP Means and How It Works
RTP is the theoretical percentage of all wagered money a slot pays back to players over an enormous sample of spins. If a game lists 96 percent, its math is built so that, across millions of rounds, it returns about $96 for every $100 staked. The flip side is the house edge: the portion the operator keeps. A 96 percent slot carries a 4 percent house edge, a 98 percent slot a 2 percent edge, and a 99 percent slot just a 1 percent edge. Choosing higher RTP is simply choosing a smaller built in disadvantage. For a fuller primer, see our guide to how slot RTP works.
Two points matter most. First, RTP is a long run average, not a session promise. Over your next 100 or 1,000 spins, results can land far above or far below the stated figure. The percentage only converges toward its target across a sample far larger than any person plays in a lifetime. Second, RTP is calculated by the game’s certified random number generator, the audited engine that decides every outcome. You can read more in our explainer on the random number generator behind online slots.
Just as important is what RTP is not. RTP is not hit frequency, the share of spins that return any win at all. A low RTP game can pay small wins constantly while a high RTP game stays quiet for long stretches. RTP is also not volatility, the measure of how streaky the payouts are. Two slots can both list 98 percent yet feel completely different, one dribbling out steady small wins, the other paying rarely but large. Learn the difference in our breakdown of slot volatility.
What a Higher RTP Is Worth in Real Money
RTP percentages feel abstract until you turn them into dollars. The house edge equals 100 minus the RTP, and that edge is the theoretical cost of the games you play, spread across everything you wager, not just your net deposits. Because slot players cycle the same money many times, the edge compounds through repeated wagering. The table below shows the theoretical long run cost of $1,000 in total wagers at several return levels. This is an expectation across a huge sample, not a prediction for one session, but it makes the gap between a 92 percent game and a 99 percent game concrete.
| RTP (percent) | House edge (percent) | Expected cost per $1,000 wagered | Tier |
|---|---|---|---|
| 99.00 | 1.00 | $10 | Exceptional |
| 98.00 | 2.00 | $20 | Elite |
| 97.00 | 3.00 | $30 | High |
| 96.00 | 4.00 | $40 | Industry average |
| 94.00 | 6.00 | $60 | Below average |
| 92.00 | 8.00 | $80 | Poor |
The lesson is not that a high RTP game hands you money; it does not. The lesson is that the version you play sets how fast your bankroll drains on average. Moving from a 96 percent build to a 99 percent build cuts the theoretical cost of $1,000 in wagers from about $40 to about $10, a fourfold difference in expected loss for identical play. That gap is exactly why the operator selectable build below matters so much, and why chasing the highest honest RTP you can verify is a rational habit even though no percentage flips the math in your favor.
The Highest RTP Slots, Ranked
The table below ranks the best RTP slots available to online players, with provider and volatility. Where sources disagree or where a figure depends on bet level or player choices, the notes say so. Treat every number as the maximum published build; your casino may run a lower one.
| Rank | Slot | Provider | RTP (percent) | Volatility | Notes |
|---|---|---|---|---|---|
| 1 | Goblin’s Cave | Playtech | 99.32 | Low to medium | Widely cited as the highest RTP slot; uses a three hold reel format |
| 2 | Ugga Bugga | Playtech | 99.07 | Low | Figure assumes optimal hold decisions on every spin |
| 3 | Mega Joker | NetEnt | Up to 99.00 | High | Top RTP reached only at max bet; far lower on minimum stakes |
| 4 | Book of 99 | Relax Gaming | 99.00 | High | Fixed high build; a modern book style game |
| 5 | Ooh Aah Dracula | Barcrest | 99.00 | Medium to high | Classic pub style slot; provider has no page on this site |
| 6 | Jackpot 6000 | NetEnt | Up to 98.90 | High | Top figure requires max bet and Supermeter play |
| 7 | 1429 Uncharted Seas | Thunderkick | 98.60 | Low | Some sources list 98.50; Thunderkick has no page here |
| 8 | Marching Legions | Relax Gaming | 98.12 | High | Fixed high RTP build |
| 9 | The Catfather | Pragmatic Play | 98.10 | Medium | Verify the build; Pragmatic ships multiple RTP versions |
| 10 | Cat’s Soup | BGaming | 98.06 | Medium | Cluster pays with a high fixed return |
| 11 | Jokerizer | Yggdrasil | 98.00 | Medium to high | Mystery win format; check the running build |
| 12 | Money Cart 2 | Relax Gaming | 98.00 | High | Bonus only game descended from Money Train |
| 13 | Blood Suckers | NetEnt | About 98.00 | Low | Some databases list 97.66; a classic bonus clearing slot |
| 14 | Reel King Mega | Red Tiger | 97.99 | Medium | Modern take on the Reel King feature |
| 15 | Starmania | Light and Wonder | 97.87 | Low | Formerly credited to NextGen Gaming |
| 16 | Good Girl Bad Girl | Betsoft | 97.80 | Medium | Single mode figure; playing both modes drops it to about 94.20 |
| 17 | White Rabbit Megaways | Big Time Gaming | About 97.72 | High | Sources range from 97.24 to 97.77 depending on feature buy |
| 18 | Devil’s Delight | NetEnt | 97.60 | High | Older NetEnt title with a strong fixed return |
| 19 | Gunslinger: Reloaded | Play’n GO | 97.52 | Medium | Verify at your casino; some builds vary |
| 20 | Simsalabim | NetEnt | 97.50 | Medium | Long running NetEnt classic |
| 21 | Tropic Reels | Playtech | Reported near 98.95 | Low | Old hold style slot; figure less consistently verified, treat with caution |
| 22 | Monopoly Big Event | Barcrest | 99.00 | Medium | High build of a branded game; provider has no page here |
| 23 | Esqueleto Explosivo | Thunderkick | 97.60 | High | Cluster pays cult classic; Thunderkick has no page here |
| 24 | Rainbow Riches Pick N Mix | Barcrest | 98.00 | Medium | Feature select format; confirm the running build |
| 25 | Hotline | NetEnt | 97.04 | Low to medium | Retro TV theme with an extra wild line |
| 26 | Blood Suckers II | NetEnt | 96.94 | Medium | Sequel with more features and a slightly lower return than the original |
A word on ordering: the top five are separated by fractions of a percent and by the conditions attached to each build, so treat ranks one through five as a group of near equals rather than a strict hierarchy. From rank six down, small database differences of a tenth of a percent are common, which is why the notes column matters as much as the number.
The Operator Selectable RTP Caveat You Cannot Ignore
This is the most important thing on the page, so read it before you chase any figure above. Many modern slots do not ship with a single RTP. Studios certify several versions of the same game, and the operator, aggregator or game server chooses which one goes live. Pragmatic Play, for example, releases many titles in bands that can run roughly 96 percent, 95 percent and 94 percent, and in some markets even lower configurations exist. That means the identical slot, with the identical art and features, can pay about 96 percent at one casino and about 94 percent at another. Nothing on the screen changes except the number buried in the paytable.
Because of this, a review that quotes the top build is only telling you the ceiling. The floor is whatever your casino selected. This is not limited to one studio; multiple providers offer selectable RTP, and it is one of the biggest reasons the same game earns wildly different reputations across sites. It is also why our table lists maximum published figures and repeatedly says to verify.
Verify the paytable. Before you bet real money, open the game’s information or paytable screen, usually reached through a menu or an “i” button, and read the RTP stated there. That in-game figure is the one that applies to your spins, not the number in any article. If a casino runs a build well below the game’s known ceiling, choose a different casino or a different game. Fixed high RTP titles such as Book of 99, Blood Suckers and 1429 Uncharted Seas are attractive partly because they are far less prone to this kind of variation.
Top 10 Highest RTP Slots Reviewed
Short, honest reviews of the ten strongest options, including the tradeoff each one asks you to accept.
1. Goblin’s Cave, Playtech, 99.32 percent
Often named the highest RTP slot ever released, Goblin’s Cave uses a three row hold and re-spin format rather than paylines, and its enormous return comes from that mechanic. The visuals are dated and the wins are modest, so this is a game you play for the math, not the spectacle. If you want the smallest house edge on the market and do not mind a retro look, it is hard to beat.
2. Ugga Bugga, Playtech, 99.07 percent
Ugga Bugga pairs a jungle theme with a two stage hold mechanic across ten hands, and the quoted 99.07 percent assumes you make sensible hold choices every spin. Play carelessly and your real return drops. There are no free spins or multipliers, just a lean, grinding format that many bonus hunters love for clearing wagering.
3. Mega Joker, NetEnt, up to 99 percent
This retro fruit machine is famous, and misunderstood. The 99 percent figure only appears at max bet with Supermeter play; on minimum stakes the return falls dramatically. Treat Mega Joker as a max bet game or skip it. Played correctly it offers one of the best returns anywhere, wrapped in high volatility swings.
4. Book of 99, Relax Gaming, 99 percent
Book of 99 proves a modern slot can carry a 99 percent fixed build. It borrows the familiar book format, with an expanding symbol during free spins, but strips away side features to fund the return. Volatility is high, so expect dry stretches punctuated by meaningful hits. Its fixed RTP makes it more trustworthy across casinos than adjustable titles.
5. Ooh Aah Dracula, Barcrest, 99 percent
A no frills pub style slot, Ooh Aah Dracula offers a rarely matched 99 percent return with a gamble ladder as its signature feature. It is simple and a touch old fashioned, which is exactly why the math is so generous. Availability at US facing casinos is limited, so check before you plan around it.
6. Jackpot 6000, NetEnt, up to 98.9 percent
Another NetEnt classic that rewards correct play, Jackpot 6000 hits its 98.9 percent ceiling only at max bet with the Supermeter engaged. The gamble feature and bright fruit symbols make it fun, but it is unforgiving of casual stakes. For players who commit to max bet, the return is elite.
7. 1429 Uncharted Seas, Thunderkick, 98.6 percent
Unusually for a high RTP game, this nautical themed slot is low volatility, so it pays often in smaller amounts, an ideal combination for a long, steady session. The expanding wilds and free spins keep it lively, and the near 98.6 percent return is remarkable for a game this smooth. It remains a favorite for bankroll conscious players.
8. Blood Suckers, NetEnt, about 98 percent
The original bonus clearing slot, Blood Suckers combines a low volatility profile with roughly 98 percent return, which is why casinos so often exclude it from bonus play. Frequent small wins and an easy to trigger free spins round make it forgiving. Some databases list it a shade under 98 percent, so confirm the build you get.
9. Marching Legions, Relax Gaming, 98.12 percent
Marching Legions offers a fixed high RTP with a straightforward Roman theme and a respin driven bonus. Volatility is high, so the return arrives in lumps rather than a steady trickle. It is a strong pick when you want a modern game with a certified high number rather than an adjustable one.
10. Money Cart 2, Relax Gaming, 98 percent
A bonus only game spun off from the Money Train series, Money Cart 2 drops you straight into the feature every round, which is how it sustains a 98 percent return. It is aggressively high volatility, capable of long droughts and sudden large hits. Play it for the thrill of the collect mechanic, not for steady returns.
High RTP Slots by Software Provider
Return often tracks the studio behind a game, because each provider makes its own math choices. Here are the strongest high RTP names organized by developer, with links to our full provider pages.
NetEnt
NetEnt is the reference name for high RTP. Mega Joker and Jackpot 6000 reach up to 99 percent and 98.9 percent respectively at max bet, Blood Suckers sits near 98 percent, and Devil’s Delight and Simsalabim both clear 97.5 percent. The studio’s older classics tend to carry fixed builds, which makes them dependable across casinos.
Playtech
Playtech quietly owns the very top of the RTP charts. Goblin’s Cave at 99.32 percent and Ugga Bugga at 99.07 percent are the two highest returning slots most players will ever find, both built on hold mechanics rather than flashy features.
Relax Gaming
Relax Gaming has leaned into fixed high builds. Book of 99 hits a clean 99 percent, Marching Legions reaches 98.12 percent, and Money Cart 2 holds 98 percent. Because these are fixed, they are less exposed to operator level RTP reduction than adjustable titles.
Big Time Gaming
The Megaways inventor is better known for volatility than for chart topping RTP, but White Rabbit Megaways lands near 97.72 percent depending on whether the feature buy is used. Expect big swings alongside that return.
Betsoft
Common on offshore rosters, Betsoft’s Good Girl Bad Girl reaches 97.8 percent in a single mode, though selecting both modes at once cuts the effective return to about 94.2 percent, a neat example of how one game can carry several numbers.
Pragmatic Play
Pragmatic Play is prolific and famously multi build. Titles like The Catfather can reach 98.1 percent, but most headline slots ship in bands that let operators run 96, 95 or 94 percent. With Pragmatic more than anyone, checking the in-game paytable is essential.
Yggdrasil and Red Tiger
Yggdrasil’s Jokerizer reaches 98 percent, and Red Tiger’s Reel King Mega sits at 97.99 percent. Both are strong upper tier options, though Red Tiger in particular offers adjustable builds, so verify before you commit.
BGaming and Light and Wonder
BGaming’s Cat’s Soup delivers 98.06 percent through a cluster pays format, popular at crypto friendly and offshore casinos. Light and Wonder, which now houses the old NextGen catalog, carries the low volatility Starmania at 97.87 percent.
A few standout games come from studios without a dedicated page here, including Thunderkick, maker of 1429 Uncharted Seas, and Barcrest, maker of Ooh Aah Dracula. We name them in plain text rather than link them. You can also browse our full lists of most popular slots and the newest slot releases to see how high RTP titles slot into current lineups.
High RTP but High Volatility Versus High RTP but Low Volatility
Two slots can share the same return and still deliver opposite experiences. This is the distinction that trips up most players who assume a big RTP means a smooth ride. It does not. RTP tells you the long run payout share; volatility tells you how that payout is distributed across your session.
High RTP with high volatility. Mega Joker, Book of 99 and Money Cart 2 all pair elite returns with punishing variance. You can lose many spins in a row, then land a single large hit that accounts for most of your return. These games are exciting and can pay big, but they demand a larger bankroll and patience. They are covered further in our guide to high volatility slots.
High RTP with low volatility. Blood Suckers, 1429 Uncharted Seas and Starmania combine strong returns with steady, frequent small wins. Your balance moves in gentle waves rather than cliffs, which stretches playing time and makes these the classic choice for clearing bonus wagering. See more in our roundup of low volatility slots.
Neither profile is better; they suit different goals. If you want the longest possible session for a fixed budget, favor low volatility high RTP. If you are chasing a big score and can absorb the swings, high volatility high RTP is your lane. If a life changing top prize is the aim, note that most jackpot slots carry lower base RTP because part of every bet funds the prize pool.
Legal US Casinos Versus Offshore Casinos
Where you play shapes the RTP you actually receive, and US players face two very different worlds.
US regulated online casinos. In states with licensed online casino gaming, operators run games from studios like NetEnt, Light and Wonder, IGT, Playtech and Pragmatic Play under a state regulator. These jurisdictions typically publish or audit return figures, and many titles run at or near their published high builds. If you live in a regulated state, this is the safest place to find dependable RTP; see our directory of legal US casino sites and our overview of playing real money slots.
Play in a regulated state. Licensed lobbies audit their return figures, so the published RTP is enforced. Legal US Casinos
Offshore casinos. Sites licensed outside the United States serve players in states without legal online casinos, and they lean heavily on RealTime Gaming, Betsoft, BGaming and similar studios. Offshore RTG and Betsoft titles frequently run at lower or operator configurable returns, and oversight is lighter, so published figures are less reliable. Some reputable offshore brands do list RTP in their help files, but you should verify each game rather than assume. Our offshore casino guide explains the tradeoffs. Whichever route fits your state, you can try any title risk free through our free slot demos, and our roundup of mobile slots flags the high RTP games that play cleanly on a small screen.

The practical rule: a regulated lobby with a fixed high RTP NetEnt classic is a stronger bet than an offshore version of an adjustable game whose build you cannot confirm.

Why High RTP Does Not Mean You Will Win
High RTP improves your odds; it does not reverse them. Even a 99 percent slot keeps a house edge, meaning the math still favors the casino over time. Choosing high RTP shrinks that edge from, say, 4 percent down to 1 percent, which slows how fast a bankroll erodes, but it never turns the game positive for the player.
The reason a great RTP can still hand you a losing session is variance. RTP is measured over millions of spins; your session is a tiny slice of that. In the short term, a high volatility 98 percent slot can take your whole balance before it ever pays the big win that justifies its number. Conversely, you can win on a low RTP game through pure luck. RTP is a long run tendency, not a session guarantee, and no slot is ever “due” to pay because each spin is independent under the certified random number generator.
So use high RTP as one sensible factor among several, alongside volatility, hit frequency, features and your own budget, rather than as a promise of profit. The smartest use of a high RTP slot is to make a fixed entertainment budget last longer, not to expect it to grow.
How to Find and Verify a Slot’s RTP
Never rely on an article alone, including this one. Confirm the figure at the source before you wager.
- Open the in-game paytable. Launch the slot and find its information screen through the menu or the “i” button. Reputable games state the RTP there, and that number reflects the exact build your casino is running.
- Check the provider’s official site. Studios such as NetEnt publish game specs, including RTP and max win, on their own pages. That is the ceiling figure; your casino may run lower.
- Compare across a couple of databases. If independent slot databases agree on a figure, confidence is higher. If they disagree, assume the game has multiple builds and rely on the in-game number.
- Watch for conditional wording. Phrases like “up to,” “at max bet” or “optimal play” mean the top figure is not the default. Mega Joker, Jackpot 6000 and Ugga Bugga all fall into this group.
- Re-check after updates. Operators can switch builds, and providers occasionally revise math. A number you verified last year may not hold today.
Common High RTP Mistakes to Avoid
Even players who seek out high RTP slots leave value on the table through a handful of repeatable errors. Steer clear of these.
- Trusting the review number over the paytable. The figure in any article is the ceiling. The build your casino runs is what counts, and only the in-game information screen shows it.
- Playing conditional games at the wrong stake. Mega Joker and Jackpot 6000 only reach their headline return at max bet. Betting minimum on them throws away most of the advantage you came for.
- Confusing high RTP with frequent wins. Return and hit frequency are separate. A 99 percent game can go cold for a long stretch, and that is normal, not a fault.
- Ignoring volatility. A high RTP high volatility slot can burn through a small budget before its big win ever lands. Match the volatility to your bankroll, not just the RTP.
- Assuming a game is due. Each spin is independent under the random number generator. A slot that has paid nothing is no more likely to hit on the next spin.
- Overlooking bonus exclusions. Casinos often bar the best low volatility high RTP titles from wagering play. Read the bonus terms before you count on a game to clear a requirement.
Frequently Asked Questions
What is the highest RTP slot?
Goblin’s Cave by Playtech, at 99.32 percent, is the most commonly cited highest RTP slot online. Ugga Bugga at 99.07 percent, plus Mega Joker, Book of 99 and Ooh Aah Dracula around 99 percent, sit just behind it.
What counts as a high RTP slot?
Anything from about 97 percent upward is generally considered high, with 96 percent as the rough industry average. Returns of 98 percent or more are exceptional, and 99 percent is about as high as online slots go.
Does high RTP mean I will win more often?
No. RTP is not hit frequency. A high RTP slot can pay rarely but large, while a lower RTP slot can pay small wins constantly. High RTP lowers the house edge over the long run, but it does not make wins more frequent in a session.
Can two casinos offer the same slot at different RTP?
Yes. Many games ship in multiple certified builds, and each operator can choose which to run. The same title can pay about 96 percent at one casino and about 94 percent at another, which is why you should always check the in-game paytable.
What does 98 percent RTP mean?
It means the slot is designed to return about $98 for every $100 wagered across a very large number of spins, leaving a 2 percent house edge. It does not predict any single session, which can run well above or below that figure.
How do I check a slot’s RTP myself?
Open the game’s information or paytable screen through the menu or “i” button. The RTP listed there reflects the exact version your casino is running, which is the only figure that applies to your spins.
Are high RTP slots better for clearing bonuses?
Often yes, especially low volatility high RTP titles like Blood Suckers and 1429 Uncharted Seas, because steady small wins help you meet wagering requirements. Note that many casinos exclude these very games from bonus play for exactly that reason, so read the terms first.
Do offshore casinos offer lower RTP?
They can. Offshore rosters lean on providers like RealTime Gaming and Betsoft whose titles often run lower or operator configurable returns, with lighter oversight than US regulated sites. Verify each game’s paytable rather than trusting a general figure.
Is a higher RTP always the better choice?
Not by itself. Volatility, features, hit frequency and your budget all matter. A high RTP high volatility slot may drain a small bankroll faster than a slightly lower RTP low volatility game, so match the profile to your goal.
Why do some RTP figures say “up to” or “at max bet”?
Because the top number is conditional. Games like Mega Joker and Jackpot 6000 only reach their peak RTP at maximum bet, and hold games like Ugga Bugga assume you make optimal decisions. Play differently and your actual return is lower.
Do jackpot slots have high RTP?
Usually not in the base game, because a slice of every bet funds the progressive prize. Their headline appeal is the top prize, not the return, so they typically sit below the fixed high RTP classics on this page.
Can a slot’s RTP change over time?
Yes. Operators can switch to a different certified build, and providers occasionally update a game’s math. A figure that was accurate last year may not match the version live today, so re-verify periodically.
Play Responsibly
A leaner house edge still tilts toward the operator, so a 99 percent game changes the speed of the math, not who it favors. Before you spin, fix a dollar limit and a time limit, stake only money whose loss would not dent your week, and step away once you reach either boundary instead of pressing to recover it. Measure the outing by whether it was fun rather than by the final balance, and keep the whole thing filed under recreation. Anyone who senses their play slipping past those limits can talk with trained counselors around the clock, at no cost and in full confidence. Access is limited to those who have reached the legal betting age in the place they are playing from.
