The Highest RTP Slots in Review

You can enjoy some of the highest RTP slots in 2025 at any of the above named online casinos. But what sort of games are we talking about? Let’s find out more about such slots that offer high payouts and Return To Player values.

1. The Catfather

This fun slot from Pragmatic Play is based on another popular slot called the Dogfather. In turn, that is a pun on the popular movie franchise The Godfather. So naturally, our feline friends featuring in this low volatility slot are gangsters. Its colorful imagery and engaging sounds will keep you purring with delight for hours on end.

There’s all kinds of characters, including a distinguished ginger tom with a trilby and monocle. Not to mention the modern-day hoodrat decked out in shades and plenty of gold bling. Full of interesting gameplay mechanics like Random Stacked Wilds, scatters and free spins, there’s a potential payout of 5,000x up for grabs. 

But the most attractive quality The Catfather offers is an enormous Return To Player value of 98.10%. This puts the slot comfortably among the highest paying games around in 2025. Released in 2016, the game is fully compatible with modern tablet and smartphone devices, both Android and iOS. 

• Return To Player: 98.10%
• Max Payout: 5,000x

2. Paydirt

Another Realtime Gaming (RTG) release found at some of our highly rated casino sites, Paydirt offers you 25 paylines across the five reels. The game transports you back to the gold rush era, where you must search for gold. A 10,000x maximum bet awaits you, while lucky players can randomly trigger a progressive jackpot for further lucrative rewards.

Depending which casino you use, its Return To Player percentage can be as high as 97.50%. Which is possibly why the game has proven so popular with slots fans for as long as it has. That and its many fun gameplay elements, including scatters, multipliers and engaging bonus rounds.

Recently, the game had something of a makeover. As a result, Paydirt is now completely compatible with mobile technology and benefits from much sharper graphics. Despite this, it’s managed to retain all of the charm of the original release. 

• Return To Player: 97.50%
• Max Payout: 10,000x

3. Cleopatra’s Gold

One of many progressive jackpot titles produced by Realtime Gaming, this slot is notable for several reasons. Although it’s an older game, having first hit the market back in 2013, it’s remained popular in part due to its classic theme and gameplay elements.

Slots based on Ancient Egypt are always fan favorites. So with lots of hieroglyphs, scarab beetles and Ankh symbols spread across the 5×3 reel layout, Cleopatra’s Gold checks all of those boxes. But it’s the progressive jackpot which appeals most of all. It has been known to climb above half a million dollars, which is surely a prize fit for a Pharoah. 

When progressive slots offer such sizable potential payouts, their RTP value tends to be much lower than the average casino slot title. But that’s not the case at all with Cleopatra’s Gold. In fact, the theoretical Return To Player is as high as 97.50%. Give it a try at Wild Casino.

• Return To Player: 97.50%
• Max Payout: 50,000x

4. Penguin Power

Travel to the Antarctic for this freezing but fun casino game, which is one of the highest RTP slots found at our top-rated casinos. Make use of 20 paylines, as well as wilds, scatters and free spins, to find a maximum potential win of 2,500x your bet.

The game’s RTP setting of 97.50% is comfortably above average, which goes some way to explaining its appeal. But that aside, the slot is packed with cute and charming baby penguin depictions. Not to mention igloos, sea lions, fish and frosty playing card symbols to round out the theme. It’s hard not to love the overall aesthetic of this release.

You can spin the 5×3 reels for as little as 0.01 coins, making the game attractive to lower stakes, casual players. But the high rollers aren’t left out, with a possible maximum bet of 100 coins.

• Return To Player: 97.50%
• Max Payout: 2,500x

5. Caesar’s Empire

Travel back through time to the days when Julius Ceasar led one of the greatest ever historical empires. Such ancient-themed slots are always a big hit, so it’s little surprise to see that this 2011 has become a true classic of the genre. You can find it at Bovada, as well as many more of our highly recommended casino sites.

With 20 paylines and a standard 5×3 grid layout, Caesar’s Empire makes use of simple but traditional gameplay mechanics. Quick and easy to learn, there’s nothing overly flamboyant about this slot. But players keep coming back for the chance to win a maximum bet of 15,000x, coupled with a shot at the progressive jackpot.

A lucky player will randomly trigger that prize from time to time, which routinely grows to five figure amounts. But in the meantime, you can enjoy a generous Return To Player rate of 97.00%, to help keep your bankroll intact for as long as possible.

• Return To Player: 97.00%
• Max Payout: 15,000x

6. Mega Fortune

Dating back to 2009, Mega Fortune is a smash hit release from the multi award-winning Swedish casino company NetEnt. So popular was this game that a 2014 sequel appeared and enjoyed massive success of its own. But despite that, many top casinos still run with its predecessor, due to the dedicated following built up by the original title.

Following a traditional 5×3 reels layout with 25 paylines, this is a slot for all players to enjoy. Casual gamers can bet from as little as 0.10 coins, while the maximum bet is a much chunkier 50 coins. The highlight of Mega Fortune is that massive progressive jackpot, however. It has been known to pay out $20.28 million in a single spin!

Given the theme, high rolling players should be quite at home with Mega Fortune. After all, the reels are adorned with depictions of high-end status symbols, like sports cars, fancy watches, speedboats and bricks of dollar bills.

• Return To Player: 97.00%
• Max Payout: $20.28 million (progressive jackpot)

7. Instant Inferno

This 2025 release, which can be played at Ignition casino, along with many others, has a flaming hot theme. The vivid orange and red colors dominate the backdrop, while symbols on the reels all boast fiery imagery.

Instant Inferno is very much based on those older, classic slots and fruit machines from years gone by. You’ll see pieces of fruit, BAR signs and bells on the 5×3 reel setup, albeit these symbols have a hellish twist. The clapper of the bell, for instance, is styled like the devil’s trident. Even the cherries appear to be red hot from the spiralling temperatures.

There are 30 paylines available in Instant Inferno, to help you win a potential maximum prize of 5,000x your stake. Betting limits range from a minimum of just 0.30 coins, through to a top end of 150. The 96.63% is comfortably above the industry average, positioning the game as one of the better paying slots around today.

• Return To Player: 96.63%
• Max Payout: 5,000x

8. Times Vegas

This Rival Gaming release is another of the highest RTP slots that feature both a progressive jackpot and an old-school Las Vegas theme. Found at Cafe Casino among others, the theoretical payout for this title is an impressive 96.47%.

The game feels fairly simplistic, with a classic looking design of 3×3 reels. All of the graphics make it resemble one of the old fashioned slots cabinets that you’d have encountered in an arcade back in the day. With just three paylines to use, you’re aiming to collect BAR symbols, Lucky 7s or cherries.

Landing three 10x symbols will net you the biggest prize of 5,000x your bet. But if you play the progressive jackpot version, you could randomly trigger an even blogger prize. The 10 Times Vegas jackpot is usually a five-figure amount and has been known to rise up to $30,000.

• Return To Player: 96.47%
• Max Payout: $100,000 (progressive jackpot)

9. Shopping Spree

This is another Realtime Gaming classic, which can be found at several of our recommended high RTP slots sites. First released way back in 2009, it continues to prove a hit with fans to this day. Its theme is exactly as the name implies, one of consumerism and lavish spending.

Female slots fans are very much the target audience, with shoes, lipstick, sparkling jewelry and perfumes all found adorning the reels. The game features 9 paylines and a maximum bet size of $1.25 per line. But the most attractive element is undeniably the sizable progressive jackpot. Towards the end of 2020, Shopping Spree rewarded one lucky winner with a whopping $5,467,358 payout.

This title was so popular that it led to the production of Shopping Spree II. In this version, RTG improved upon the graphics to further enhance the playing experience. However, despite the release of a sequel, the original has retained a dedicated following.

• Return To Player: 95.44%
• Max Payout: $5,467,358 (progressive jackpot)

10. Absolootly Mad

Microgaming’s hugely popular Mega Moolah slots series is well known for creating millionaires out of its dedicated following. In fact, these games repeatedly break world records for largest casino payouts, the most recent of which belongs to Absolootly Mad: Mega Moolah. One Belgian-based gamer staked just $18.30 before hitting the barely believable jackpot of $23.4m.

These titles are popular in both online and physical casinos across the whole world. The payouts grow so large thanks to the huge international network of progressive jackpot slots. These crazy payouts are the main reason for the inclusion in this list. The base RTP of Absolootly Mad is actually only 92.02%, but it’s massively offset by the sheer scale of the potential prizes.

This specific Mega Moolah variant uses a 5×3 grid layout, with 25 paylines and four different sized jackpot levels. The design is loosely based on Lewis Carroll’s Alice series, with Microgaming’s own version of the Mad Hatter and his tea party.

• Return To Player: 92.02%
• Max Payout: $23.4m (progressive jackpot)

The Best Paying Sites for Slots

So now we have plenty of ideas about which games to play in order to maximize our potential returns. But where do we play them? Let’s take a detailed look at some of our most trusted casinos.

1. Wild Casino – Our favorite site for playing the best RTP slots

This quality casino with a Curaçao license is fast becoming recognized as one of the best roulette sites around. But its range of casino slots is not exactly bad, either. You’ll find plenty of the highest RTP titles here, including some progressive jackpot slots. 

Among the newer releases are enjoyable games such as Mystic Wolf, Leprechaun Frenzy and Hot Joker Hot Fruits. But there are several well-known classics of the genre to be found too. Not to mention the many other casino table games, both live dealer and traditional RNG.

Another huge selling point of Wild Casino is the selection of banking options. There’s a secure and convenient option for everyone here, including over a dozen different cryptocurrency tokens. These super quick withdrawal methods are a major reason why this site is known as one of the internet’s top fast payout casinos.

And finally, a word about the many promotions. Existing and new players alike will enjoy the selection of bankroll boosting bonuses. The highlight of which is one of the biggest welcome offers of any online casino. Use the Wild Casino promo code CRYPTO300 to bank a 300% match on your first deposit. Over the next four deposits, you can earn an additional $6,000 too, for a maximum bonus of $9,000! This bonus carries a 35x wagering requirement.

2. Ignition – Selection of the best payout slots online

Where to begin listing the good points with this high quality casino? Should we discuss the fact that the loyalty program is one of the top rewards schemes of any online wagering site? Or perhaps mention that fantastic peer to peer poker room, which offers both cash games and tournament play?

Since you’re probably keen to hear about the range of high RTP slots, let’s start there. Among the game library you’ll find hundreds of titles, including some with innovative new gameplay mechanics and a whole bunch of classic names. There’s also a wide selection of progressives, plus new titles like 10 Times Vegas and Sugar Smash.

Another notable element of this top class all-round wagering site is the selection of casino bonuses. The most generous of these has to be the signup offer, especially if you opt to deposit using a crypto token such as Bitcoin. Do so and you’ll score a massive 150% match bonus of up to $3,000 and you don’t even need an Ignition promo code. 

Watch out for the 25x turnover requirement attached to the bonus. However, with so many fantastic slots offering generous RTP rates, it shouldn’t be a problem to burn through the required playthrough amount.

3. Las Atlantis – The highest RTP slots of any new casino

It can sometimes take new slots sites a little while to gather momentum, but Las Atlantis has experienced no such problems. Already known for its extremely flexible welcome offer, rapid payout times and its selection of games with large RTP rates, we’ll be surprised if you’ve not heard of it yet.

Licensed and regulated by the government of Curaçao, Las Atlantis is a slot lover’s dream. There are hundreds of titles in the library, including new releases like Thai Emerald, Twister Wilds and Copy Cat Fortune. But there’s really something for everyone, with old classics like Caesar’s Empire and Bubble Bubble, cutting-edge new titles, plus a whole bunch of progressive jackpots.

Cryptocurrency fans will enjoy the fact that you can fund your account using Ethereum, Litecoin and Bitcoin. While everyone will be pleased to see just how many different casino bonuses there are at Las Atlantis.

New registrants can make their first deposit using the Las Atlantis promo code LASATLANTIS for a chunky 280% slots bonus. That features a 35x turnover requirement, as do most of the offers at this casino. But if that doesn’t do it for you, try one of the many other welcome promos instead. Some of which offer free spins on selected high RTP slots titles. 

4. Slots.lv – Home to some of the best paying online slots

Pay attention to this casino’s name for a clue as to what they’re all about. That’s right, you guessed it! They’re one of the best blackjack casinos on the internet. Just kidding! Though that might well be true, Slots.lv is focused on bringing you the best selection of video slots and progressive jackpot games.

Some of the newer releases on offer include Tiger Temple, Robyn and Raving Wildz, which join the hundreds of other enjoyable titles found here. You’ll struggle to find a better selection of high Return To Player games, while the number of payment methods on display is also super convenient. 

There’s a case to say that Slots.lv is one of the top Bitcoin casinos around, too. Especially when you consider its extremely quick payout times and selection of crypto bonuses. And speaking of promotions, expect to find plenty of deals for existing players, along with a generous rewards program.

New players can benefit from a healthy signup offer, too. Use the Slots.lv promo code HELLOSLOTS200 for a 200% deposit match with a turnover requirement of 35x. That’s good for a maximum of $1,000.

5. Cafe Casino – Up and coming US casino site

There’s much to enjoy about Cafe Casino, a site that’s fast carving out a strong reputation. Although there are many live casino titles and RNG table games to play, it’s the slots catalog which catches the eye. Not to mention the frequent tournaments, where players can win bonuses simply for spinning the reels of their favorite games.

The blend of games is good, with high RTP titles, lots of high and low volatility games and some real classics thrown into the mix. But they frequently update the library too. Examples of recent new additions include Dragon Scroll, Fortune Turtle and Li’l Red. And if you’re after a massive payout, get involved with some of the many progressive jackpot games.

On the subject of large cash sums, this casino is one of the better high limit slots sites around at the moment. And if you do want to deposit a good amount of money, make sure to use the Cafe Casino promo code CCBTCVIP. That way, you’ll secure a healthy 350% deposit match bonus worth up to $2,500.

That offer does come with a 40x wagering requirement attached. So do keep that in mind when playing with bonus funds.

What Does Return To Player mean?

Every casino game, not only slots, has an RTP value. It is a theoretical figure which indicates the house edge, if you play the game over an infinite length of time. 

An RTP of 98.50% means that, for every $100 worth of spins, you should expect to lose $1.50 and see $98.50 worth of prizes.

How Slots RTP & Payouts Work

Unfortunately, you cannot take the Return To Player percentage too literally. While it is a strong indicator of how generous the slot is, every spin is still random. If it were not, the games would be too predictable and not much fun.

Another important element of the game’s mechanics comes into play to determine how prizes are paid. This is known as volatility. It’s this factor which influences how frequently the game will award prizes. 

A high volatility title will tend to pay out less often than a lower one. However, those prizes will be larger than average, while they will be smaller in a lower volatility game.

How to Find the RTP of Casino Slots

The best place to look up a slot’s RTP percentage is at the casino you’ve chosen to use. Most offshore casinos are happy to display such information on the site, which makes it easy to find. But not all casinos do this, in which case you’ll need to visit the game developer’s website.

If all else fails, reach out to the customer support team at your favorite casino, or contact the software supplier directly.

Conclusion

Now that you understand all there is to know about the internet’s highest RTP slots, it’s time to spin some reels! 

If you’re keen to get started, but don’t know where to play, try Wild Casino. The incredible $9,000 welcome package is as good a reason as any to join today.
