Best RTP slots (96%+): Find the highest payout online slots

Now, the best RTP slots take you on a wild ride that combines the drama of modern-day video games with sky-high jackpots - and potential wins.

In this article, our experts review and rate the best slot sites for winning real money in 2025. We'll be highlighting their most popular slot games, explaining how payout percentages work, and sharing the best tips and tricks that will help you get off to the best possible start.

Pros:

Cons:

Ignition has it all when it comes to slots: It’s got the highest RTP slot games, the biggest variety, and it crushes it when it comes to Bonus Buy choices and exclusive titles.

It’s our top pick, and you can get started with a $3,000 welcome bonus.

Online slot machines: 5/5

Slots have come a long way over the last years, and as solid proof of that, we point you to Ignition’s game library. Here, the likes of Golden Furlong, 15 Coin Bank Bust, and Coins of Zeus combine advanced gameplay with high payout percentages.

Instant Inferno, meanwhile, is just one prime example of what we meant by Ignition hosting a huge variety of slots. It stands out above the rest with its electrifying visuals and sounds that meet modern-day gaming standards when it comes to graphics.

A Night With Cleo is tagged as explicit, but that just increases the risk factor. And while it doesn’t quite reach the heights of Tomb Raider in terms of there being any chance of it being turned into a movie just yet, its adult theme, solid RTP, and iconic main character make it a fan favorite.

Bonuses and promotions: 4.8/5

You can start your spinning-and-winning adventure at Ignition with a $3,000 welcome bonus. This is a matched deposit offer for which you’ll need to deposit at least $20 in order to claim, but there’s no need to enter any promo codes.

This substantial bonus plays its part in supporting the casino's game diversity. It is split between the poker room and all the other casino games, including slots, giving you a fair chance to have a little taste of everything.

Then, each time you play any slot games, you’ll earn points known as Ignition Miles. You can keep racking up these points before converting them anytime you want into bonus funds or cash.

Payment methods: 4.8/5

Ignition supports all major credit and debit cards like AMEX, VISA, and MasterCard, as well as 5 cryptocurrencies, with Bitcoin, Litecoin, and Ethereum all available.

The minimum deposit is just $20 for each method, with max limits usually landing in the $2,000 - $2,500 ballpark. First deposits are free, but you’ll be charged a minor fee for any subsequent non-crypto deposit.

For withdrawals, you also have the option of using MatchPay, Zelle, and Voucher, and same-day payouts are often available at Ignition.

User experience: 5/5

The UX at Ignition is one of the reasons it landed in the top spot for us. This is an incredibly pain-free casino site to join and use. All the games are easy to find, thanks to neat categorisation, and there are very few menus and links. This works well towards creating a distraction-free space for players.

The website works perfectly on all devices, and while some might suggest the design needs a refresh, Ignition has consistently stuck to a branding and aesthetic that’s both professional and functional.

Live chat 24/7 is available, and you can also contact the customer support team via email.

Pros:

Cons:

If you’re the kind of gamer who’s constantly on the lookout for the latest new releases, BetOnline regularly updates its roster with the hottest new high RTP slot games.

You can kick-start the fun with 100 free spins and play over 1,200 slots in total.

Online slot machines: 4.8/5

Some of the most eye-catching new games added at BetOnline include Bass Bounce, a sequel to the enormously popular Big Bass Bonanza franchise. Then, Coins of Leprechaun, and Lady Hot Gun, a slot game driven by a strong female character who could give Resident Evil’sAda Wong a run for her money.

Permanent residents at BetOnline, meanwhile, include the exclusive Triple 7s and even Gold Nugget Rush, a goldmine-themed slot game by BetSoft that has a 96.03% RTP.

Slam Dunk Spins, as a sweet treat, is locked and loaded with bonus rounds and free spins, while Piggy Thief took us back to the classic platform games when we tested it.

Bonuses and promotions: 4.75/5

BetOnline isn’t currently offering a matched deposit bonus for slots players. Instead, as a new customer, you can opt for 100 free spins. The way this offer works is you’ll receive 10 free spins for the first 10 days, with each spin expiring on the day you receive it.

During your first 10 days (and beyond), you can continue to claim other offers at BetOnline, including the chance to win $20 when you play the Game of the Week here.

There are also cash tournaments taking place each week, while a referral bonus and VIP rewards are the best ways to get treated for your loyalty.

Payment methods: 4.55/5

VISA and other major credit and debit cards are the simplest way to fund your account if you’re not playing with crypto. The minimum deposit is just $25, and you can deposit as much as $2,500 per transaction.

If you need to deposit more, you can use crypto or money orders, although the latter has a high $300 minimum deposit.

For payouts, P2P, money orders, bank wire transfer, and checks are the regular payment methods, with credit and debit card withdrawals unavailable. Crypto payouts are the fastest way to receive your money, but it's worth noting that some crypto withdrawals come with a $100K cap.

User experience: 4.75/5

A lot is often written about the fact that BetOnline is over 25 years old. And it’s true – this is one of the world’s oldest and therefore most reputable slots sites that’s been fine-tuning its game selection and interface for nearly three decades.

It continues to look new and fresh, thanks to recent updates to the site design, and site load speed is right up there with all the other top-rated online casinos.

Keeping some of that old world charm, you can reach the customer support team via toll-free phone support, which is perfect if you feel you need to speak to a human agent.

Pros:

Cons:

If you’d love to break the bank and take home some serious loot, Slots of Vegas provides you with ample opportunities. It recently won an award for having the ‘highest jackpots’, and games like Aztec’s Millions are the reason why.

Online slot machines: 4.75/5

Let’s start with Aztec’s Millions, a high RTP jackpot slot that has a stupendous win potential of over $2,000,000. For a more modest and perhaps more attainable jackpot, you can also play Shopping Spree II ($250,000+) and Jackpot Pinatas Deluxe ($340,000+).

If the thought of playing for such big sums makes you nervous to the point where you’ll make mistakes, you can play all the games at Slots of Vegas in demo mode first to get some practice in.

Other high RTP games include Sweet 16 Blast!, which should suit anyone who rode the Candy Crush traina few years back, and Sparkling Fortunes, an enchanting online slot game that gave us major Disney vibes when we tested it – but with a better soundtrack!

Bonuses and promotions: 4.55/5

You’ll need to put $30 into your account as a new player if you want to unlock Slots of Vegas’s 250% welcome bonus. This is a bumper offer worth up to $2,500, and you’ll find that it comes with 50 free spins.

You can then keep checking back each day to see what daily deals are up for grabs here, with Slots of Vegas regularly releasing bonus codes for deposit bonuses, no deposit bonuses, and free spins all week long.

That said, the best offers and perks are to be found in the 5-tiered VIP program. This is an invite-only scheme that rewards dedicated players with more free spins, appreciation chips, cashback, and different kinds of goodies.

Payment methods: 4.7/5

Slots of Vegas’s list of deposit options is pretty much limited to cryptocurrencies and debit and credit cards. This should be good enough for most players, as should the reasonable $30 minimum deposit.

A $100 maximum deposit limit is in place for VISA, but you can deposit more per transaction if you use AMEX, Discover, MasterCard, or crypto.

For payouts, Coindraw is the fastest and simplest way to receive your winnings. It comes with zero fees and almost instant processing times. Bitcoin, bank transfer, and check are the alternative options, but each one includes a minor fee.

User experience: 4.7/5

Slots of Vegas gives you the chance to download their software or stick to Instant Play games. You can access the slots on any device, including your tablet, though we found that the Instant Play games load the quickest.

You won’t, however, get access to all the games or the proper site design until you create an account and log in.

Cool little touches include a ‘Latest Winners’ section on the homepage that updates you in real time with the latest jackpot wins secured by other players, while customer support is available through 24/7 live chat and email.

With cute, furry aesthetics and daily offers, Queen Bee Casino is buzzing with excitement. It’s got a flurry of bonuses, including a huge $5,000 welcome package, and is our recommended choice for players who love a good deal.

Online slot machines: 4.55/5

There are over 1,300 slot games altogether at Queen Bee Casino, so players have a great selection to choose from. The bumble bee theme is present and correct on games like Mo Honey Money, which has a 95.45% RTP and unique bonus rounds.

When it’s time to spread your wings and try something different, you can hop on over to high RTP slots like Lava Fruits, the entertaining 88 Flying Monkeys, and Carnival Rush, a so-called ‘Bonus Mania’ that stretches your dollar as far as possible.

Other popular picks here include Coins of Christmas, a 96.18% RTP slot game in which Santa brings you presents every day of the year. He must be getting kinder in his old age!

Bonuses and promotions: 4.8/5

A range of tantalising bonus offers is at your fingertips at Queen Bee Casino, and all you need to do is make a minimum deposit to claim them. They include a welcome bonus worth up to $5,000, which comes with 200 free spins and a low $20 minimum first deposit.

Other highlights include a 15% weekly rebate, which puts cash back in your pocket after a week playing slot games, and an 88% up to $500 reload bonus each Monday.

In keeping with the overall theme of this casino site, there’s also a ‘Honey Pot Reload’ bonus each Wednesday. If you deposit anything between $50 and $200, Queen Bee Casino will match it 100%.

Payment methods: 4.4/5

Queen Bee Casino shares a list of deposit and withdrawal methods with most popular slots sites. This means you can deposit via credit and debit cards like VISA and MasterCard, but you can’t withdraw using them.

Instead, only crypto and money orders are available for withdrawals. Crypto is the most flexible option, available through Bitcoin and Litecoin, and coming as it does with low $20 min deposits and high $1,000,000 max deposit limits.

Money orders, on the other hand, have a high $1,000 minimum withdrawal limit in place. If you really want to take home your money using a regular payment method, P2P has a lower $50 minimum withdrawal limit.

User experience: 4.4/5

While Queen Bee Casino may share its shell with other slots casinos, its bright pink colour palette helps to set it apart. Its assortment of cartoony avatars helps to give it a friendly face, too, but there’s plenty of substance to go along with style.

Indeed, Queen Bee Casino is really easy to use, with its dropdown menus and links helping you to find your way around. The games load quickly, and the gameplay itself is smooth and exciting.

We also have praise for the in-depth Help Centre that assists you in finding answers on an array of topics, including bonuses and how the different games work. 24/7 live chat and email are also on hand for further assistance.

Pros:

Cons:

At Super Slots, you can compete against the computer – or you can compete against players just like yourself via daily Slots Races. Rivalries are formed, epic battles take place – and with $15,000 up for grabs each day, this is our top pick for tournaments.

Online slot machines: 4.65/5

Naturally, an online casino called Super Slots will be packed with slot machines. And with more than 1,300 (and counting) to choose from, this casino site justifies its name.

The daily slots races take place over in the ‘Tournaments’ section, and to compete, you just need to enter and play slots games. You can track your progress in the Leaderboard, with Super Slots rewarding the top 250 players each day with a cash prize. The more you play, the more you’ll win.

Whether you enter a tournament or not, you can play high RTP slots like Lucky Golden Joker, Bison Horizon, which has a 96.14% RTP, and the anime-inspired Boss Rush, which riffs on the popular survival game Soul Knight.

Bonuses and promotions: 4.45/5

Super Slots recently traded their matched deposit welcome bonus for 300 free spins, which will suit slot players right from the ground. You’ll receive your spins the day after you make a qualifying deposit, with all spins expiring within 24 hours.

As well as the welcome offer, Super Slots has recently revamped its entire daily and weekly offers.

It’s a shame there’s no longer a reload bonus here for non-VIPs, while you’ll only receive 100 free spins each Wednesday if you stake at least $1,500. That will seem quite steep for most players, with an unlimited referral bonus much more accessible.

Players can also take part in the Free Load tournaments and use their PRG Tournaments chips. Any rewards you win in this tournament will be available within 48 hours after the tournament ends.

Payment methods: 4.3/5

If you want to use credit or debit cards to play at Super Slots, you can only use them to make a deposit. The min deposit is set at $25, but you’ll need to use either money orders, P2P, bank transfer, or a check to take home your winnings.

That said, you can withdraw via one of 10+ cryptocurrencies, including Bitcoin, Litecoin, Dogecoin, and TrumpMeme. The minimum deposit for most crypto is $20, but it’s as high as $200 for Tether.

Same-day payouts are available for P2P, but you’ll be waiting a little longer if you use money orders, bank, or check transfer.

User experience: 4.5/5

Super Slots looks and feels like a truly professional online casino site. Its gold, purple, and white colour scheme contributes to this, giving the super functional interface an air of grandeur.

Some of the menus are a tad small on mobile devices, but shouldn’t present too much of an issue, especially once you get up to speed with where everything is.

You can self-exclude anytime via the Responsible Gambling section, but manual deposit limits aren’t yet available. If you need help, the comprehensive FAQ page impressed us, as did the speedy response time of the 24/7 live chat agents.

What we intend to bring you here is a quality list of the highest payout online slots. However, we knew that in order to do that, we also had to focus on bringing you the best online casinos that offer an all-around brilliant iGaming experience. These sites will appeal to all kinds of gamers, and will include everything from the best RTP slots to the best esports betting options.

Here’s how we did it:

We figured we’d focus on uncovering the best RTP slot machines first, with the idea being to find slot sites that have hundreds of high RTP games that give you the best chances of winning.

As a result, whichever site you join, you’ll be sure to find favorable odds, whether you play progressive jackpots, classic slot machines, or anything else!

Everyone loves free spins, which is why we added casino sites that give them away on the regular. You’ll also find deposit bonuses at some of the top slots sites in this review guide, as well as referral bonuses and VIP programs.

What’s more, the slots themselves come with bonus features that keep you in the game and nudge you towards a win.

We aimed to add the best slot sites for winning real money that are legit. To that end, we only added online casinos that support tried and trusted payment methods like AMEX and Mastercard.

If a casino site had the best RTP slot machines but supported dodgy payment methods, it didn’t make the cut.

To make sure that your time playing the best payout online slots is as smooth and hassle-free as possible, we tested each casino for its site navigation, its mobile compatibility, and its customer service.

All those in the top 10 passed each test with flying colours, and they also let you self-exclude anytime you wish.

In the end, it wasn’t enough that we based the top casinos simply on them having the highest RTP online slots. Instead, we soon realised that what also mattered was gameplay.

You know, cutting-edge graphics, sounds, and visuals that ensure slot machines are now as playable as actual video games.

To help us, we laser-focused on world-renowned game developers that are at the forefront of online casino gaming innovation in 2025. So whenever you play an online slot, you’ll be treated to an all-encompassing iGaming experience.

The easiest way to find slots with the highest RTP is to read review guides like this that point you in the direction of the best payout slot games.

You can also manually research each slot game you like the look of, with a quick perusal on Google giving you all the information you need. Sometimes, the best payout casino sites will list the RTP of each slot they host, too.

You’ll be in safe hands at the best slot sites for winning real money as long as you play at online casinos that are licensed. Such casinos are legal and legit, and they’re backed up by safety measures like SSL encryption that keep your details secure.

Even the absolute highest RTP online slots don’t guarantee that you’ll win real money. All online casino operators are essentially businesses that need to maintain a house edge in order to stay in profit, and it’s the house edge that means you’re always taking a risk whenever you place a bet.

Rather, you need to see the best payout online slots as giving you a better chance of winning. Nothing is guaranteed, but the odds will be more favourable.

As well as the RTP itself, you can increase your chances of winning by playing online slots that have lots of bonus rounds and/or bonus features, such as a free spins round that extends your game time without you staking extra money.

Playing progressive jackpots can also improve your chances of success, while playing high volatility slots instead of low volatility slots can be another smart idea.

The best online casino for high RTP slots is Ignition. In operation for more than a decade, it’s got 400+ slot games you can play, many of which have 96%+ RTPs, as well as hourly jackpots and same-day payouts.

You’ll earn points anytime you play a slot game, which you can later turn into bonus funds, while regular offers include a $125 referral bonus and free spins.

Ignition: Home to the most slots with the highest RTP, Ignition has everything, including progressive jackpots, Bonus Buy games, exclusive titles, and more. Get started today with a $3,000 welcome bonus.

BetOnline: You’ll find the hottest new high RTP slots at BetOnline, which works closely with the best software developers who are the last word in innovative online slot machines stacked with the latest features.

Slots of Vegas: You can trust a site that’s won an award for having the highest jackpots, with Slots of Vegas’s progressive jackpots giving you the chance to win life-changing sums.

Queen Bee Casino: Daily bonuses are the order of the day at this stylish casino site, with regular offers including weekly free spins and an 88% reload bonus every Monday.

Super Slots: Enter $15,000 daily Slots Races and forge new rivalries with players just like yourself who are seeking to race to the top of the leaderboard.

While a lot of people think playing slots is just a case of spinning some reels and seeing what happens, there are still a few things you can do to give yourself an advantage:

Different casino sites have different games. Some have more progressive jackpots, others have more slots with lots of bonus features, and so on.

By signing up for different sites, you can easily flip-flop between them, taking advantage of special offers when they come along, as well as new games.

Many of the best slot sites get you started with either free spins or different types of casino bonuses, with some also offering a matched deposit bonus to new players.

Either way, welcome bonuses kickstart your gambling experience, allowing you to tackle the higher RTP percentages with additional bonus funds, thereby increasing your chances of winning even more.

As a rule of thumb, a slot game that has a 95.5% RTP is generally considered to have an average payout percentage. Anything above that is deemed to have a high RTP percentage.

House edge, meanwhile, refers to the advantage that the casino has over you, the gamer. If, for example, a slot has a 97% RTP percentage, the house edge is set at 3%, which therefore means the casino should maintain a 3% profit.

All of this is important because it lets you know what your chances of winning are. The lower the house edge, the more the odds are on your side.

While higher RTP percentages can lead to frequent wins, nothing is guaranteed. Players seeking big wins should understand that the RTP percentage is just a guideline that lets you know how often a slot pays out in theory.

If, after a few attempts, your bankroll is running dry, don’t do something silly by gambling more than you originally planned. Instead, log out, take a break, and try again another time.

Remember, online gambling should always be fun.

If you’re a gamer with a competitive streak, you might want to enter Slots Races, which give you the chance to earn extra cash.

Essentially, you’re competing against real players just like yourself, with sites like Super Slots hosting daily Slots Races with $15,000+ prize pools. You just need to play as many slots as you can, and the more you win, the higher up the leaderboard you’ll climb.

New rivalries will be formed, epic battles will renew each day - but will you be the winner?

You’ll find the highest RTP slots at all the sites in this review guide, with each one carefully vetted and reviewed by our team for their game selection, potential huge payouts, and their bonuses.

Ignition came out on top, with their best RTP online slots packed with bonus features and free spins, and with all new players entitled to a $3,000 welcome bonus.
