Why gamers will love these high RTP slots sites
If you’re new to online casinos or playing slots in general, you’re probably a little bit curious to know why they’d appeal to gamers. Is it the bonuses? The fact that you can win real money? Or maybe it’s the sharp graphics, the dazzling visuals, and the crushing sounds.
Let’s see exactly why the top online casinos are appealing to more gamers:
Stunning visuals: Gone are the days of the classic fruit machines we all knew and loved in the 1990s, which, though fun, are dated. Today, the best online casinos get their slots from world-class software developers who fuse scintillating aesthetics with immersive sound for a magnetic gambling experience.
Epic themes: All slot games have themes. They take you on gripping adventures, keep you engaged with compelling storylines, and plunge you into exciting worlds, from the North Pole to outer space.
Never-ending bonus rounds: Just like when you play a video game, you can stay alive playing online slots by unlocking features, namely, bonus rounds. They let you advance to the next stage until you get closer to the pot of gold.
Cross-platform compatibility: Whether you prefer to kick back with desktop games in the comfort of your own gaming room or live for mobile games, all the best online casinos are available on all devices.
Reviews of the best RTP slots online
Now, let’s dive in and check out what features the best online slots sites have to offer.
1. Ignition (777 Deluxe) – Best RTP online slots site overall
Pros:
- $3,000 combo welcome bonus
- 400+ slot games
- Low minimum deposit
- Hourly, daily, and epic must-drop jackpots
- $125 referral bonus
Cons:
- E-wallets not supported directly
- No free spins for new players
With more than 400 high RTP slots, a $3,000 welcome bonus, and a lucrative rewards scheme that tops up your account with bonus points anytime you play a slot game, Ignition is our number one pick.
Gameplay: 5/5
Whatever your personal preferences are, Ignition caters to everyone. You can aim for huge jackpots playing games like 777 Deluxe, dig for gold in the old Wild West via Gold Rush, or display your patriotism by playing Happy 4th of July.
The popular A Night With Cleo, meanwhile, gives you the chance to see if you can tempt the Egyptian Queen to part with her money, while the stunning Lawless Ladies unleashes plenty of girl power alongside an $8,000 jackpot.
High RTP bonus buy games are also available, and they include Golden Tiger Fortunes and Piggy Bank Bonanza. If you’re after exclusives, check out Azteca Temple of Wins, a Hold & Win game that has a 96%+ RTP.
Bonuses and promotions: 4.9/5
Join Ignition today, and you can opt in to a $3,000 combo welcome bonus for crypto players, which goes up to $2,000 if you opt for a credit card. This is split 50/50 between slot games and online poker, which means you won’t be able to use the entire amount on slots.
However, it comes with a reasonable $20 minimum deposit, and there’s no need to enter a promo code.
You can then complete a daily Scratch & Win every single day, with random prizes including free spins and up to $1 million. Other offers include weekly boosts, a $125 referral bonus, and a unique rewards program known as Ignition Miles.
Payment methods: 4.95/5
For deposits, you can use major credit and debit cards like VISA and AMEX, as well as crypto and vouchers. The minimum deposit ranges from $10 for voucher to $20 for credit and debit cards, and maximum deposits typically range from $1,000 to $2,500 per transaction.
For withdrawals, you won’t be able to use credit or debit cards. Options instead include crypto, Voucher, P2P, and MatchPay, with the latter compatible with a number of e-wallets like PayPal.
Most payouts are completed the same day, but there are a few minor fees to be aware of.
User experience: 4.95/5
Ignition is a super user-friendly slots site that’s been up and running for over 10 years. Signing up takes less than a minute, there’s no need to complete any lengthy KYC procedures, and you can play slots games on any device.
The website is SSL-secure, which means all your details are kept safe, while the interface is as smooth and responsive as any modern-day gaming console.
Customer service options include 24/7 live chat and email, and you can close your account anytime.
2. BetOnline (Coin Storm) – Best high RTP slot races online
Pros:
- 100 spins for new players
- $15,000 in prizes from daily slots races
- 1,200+ slot games
- Over 25 years online
- 20+ payment options
Cons:
- Only free spins in welcome bonus
- Card deposit fees
If you love the thought of competing against other players and aiming for huge cash prizes when you play slots, BetOnline is our top choice for daily slots races.
Gameplay: 4.95/5
BetOnline is home to over 1,200 total slot games, with choices ranging from exclusive titles to brand new releases. You can whip up a storm with Coin Storm, take on the bad guys in Riot: Brutal Skis Revenge, and enter the icy regions of Arctic Coins.
If you want to play slots races, you need to enter the ‘Promos’ section, where you’ll find a $15,000 daily cash race taking place every 24 hours. Anyone who finishes inside the top 250 will be rewarded with a cash prize, and all you have to do is play eligible slots and race up the leaderboard.
BetOnline even runs similar leaderboard competitions for games like online blackjack, so there’s something for every type of player.
Rounding things off are classic titles like Big Bass Bonanza, which is basically the slot version of Super Mario: Evergreen, never gets old, and there are lots of spin-offs and sequels.
Bonuses and promotions: 4.75/5
As a new player, you get to choose between 100 free spins or a 100% poker welcome bonus. If you’re here for slots (and we suspect you are), the 100 free spins make more sense. They’ll be added to your account in 10 daily increments, giving you the chance to prolong them for 10 whole days.
Beyond that, each week, BetOnline hosts a game of the week promotion, which is usually one of their highest RTP slots. If you play it, you could be in with a chance of winning a cash prize.
There’s also a monthly Take the Prize contest, where BetOnline gives away $25k in cash to one lucky winner, while VIP rewards are up for grabs for regular players.
Payment methods: 4.9/5
BetOnline isn’t unusual in that it lets you process deposits via credit and debit cards, but not withdrawals. However, its list of regular withdrawal methods is limited to P2P, money orders, bank transfer, and check, all of which have fairly high minimum payout limits.
It’s probably why this casino site pushes crypto so much. Not only does BetOnline support 10+ cryptocurrencies, it also has high maximum deposit and withdrawal limits, as well as instant payouts.
On the plus side, credit and debit cards come with a reasonable $25 minimum deposit, while all payouts are reliable and consistent.
User experience: 4.85/5
With more than 25 years in the game, BetOnline has grown alongside gaming developments and gamers’ tastes. It’s a smart, polished website that’s locked and loaded with features and tools, and which has a strong social media presence.
It’s also got phone support if you need a more direct answer than live chat can give you, as well as a responsible gambling section to keep you safe online.
3. Slots of Vegas (Aztec’s Millions) – Best high RTP progressive jackpots
Pros:
- 250% up to $2,500 welcome bonus
- 50 free spins for new players
- Low 10x wagering requirements on bonus
- 400+ slots
- Huge daily jackpots
Cons:
- Higher min. withdrawal
- Only one main slot provider
Award-winning slots site Slots of Vegas, one of the leading Inclave online casinos, is known to have some of the highest jackpots. You could win up to $2,000,000 playing games like Aztec’s Millions, as well as enjoy a huge 250% welcome bonus.
Gameplay: 4.85/5
Even if you don’t land the $2,000,000 jackpot, games like Aztec’s Millions are lots of fun. With epic themes, cutting-edge graphics, and catchy sounds, Slots of Vegas combines the excitement that comes with knowing you could win with the enjoyment of simply playing great games.
This also goes for other progressive jackpot slots like Spirit of the Inca, where you could win a further $250,000, as well as Shopping Spree II, which lets users win money by romping through a virtual shopping mall.
Aside from the jackpot games, Slots of Vegas has plenty of other high payout slots, including Hades’ Flames of Fortune, and our personal favourite, Shogun Princess Quest, which reminds us of fun retro platform games on the SEGA Mega Drive.
Bonuses and promotions: 4.8/5
You’ll need to create an account, deposit at least $30, and then enter the code “WILD250” if you want to trigger Slots of Vegas’s welcome bonus. It’s a 250% matched deposit offer that’s worth up to $2,500, and it comes with 50 bonus spins for specific online casino slots.
Daily deposit and no deposit bonuses are available here, as are free spins. You just need to check the promotions page, where a list of bonus codes is stored.
There’s also a five-tiered VIP program here, although you will need to keep making regular deposits in order to get invited. From the first level upwards, VIPs get daily free spins to be used on slots, making becoming a VIP well worth it.
Payment methods: 4.8/5
Slots of Vegas supports two main types of deposit methods: Cryptocurrencies and credit and debit cards. All crypto deposits are free, but credit and debit card transactions come with fees.
The minimum deposit is $30 for each option, but a $100 maximum deposit is in place for VISA. Other credit cards are capped at $1,000, and you can deposit as much as $100,000 into your account per transaction if you’re using crypto.
For payouts, Coindraw and Bitcoin are the fastest options, with bank transfer and check transfer the only current regular withdrawal methods available. Both come with a $100 minimum withdrawal limit, though this won’t be an issue if you land a big jackpot win.
User experience: 4.7/5
Among Slots of Vegas’s awards is a ‘Best Slots Casino’ award. Having tried it extensively, this doesn’t surprise us. Away from the games themselves, Slots of Vegas is extremely user-friendly, with all the menus and links loading instantly.
If you need assistance with a big payout, you can contact the customer support team anytime via email, and they will gladly help you out.
Instant play games are available, and you can easily download the software onto your mobile device for faster gameplay.
4. Queen Bee Casino (Reels & Wheels) – Largest bonuses for playing high RTP slots
Pros:
- $5,000 welcome bonus
- Weekly free spins + reload bonuses
- 1,000+ online slots
- Colourful interface and theme
- Six and 7-figure transaction limits
Cons:
- High minimum deposit for some bonuses
- Bank payouts start from $500
Queen Bee Casino may be one of the new online slots sites, but it’s got some great bonuses that rival many industry titans.
If you wish to ‘join the hive,’ you can sign up today and claim a $5,000 welcome bonus, with this top-rated casino rated our favourite when it comes to free spins and bonuses in general.
Gameplay: 4.85/5
Queen Bee Casino isn’t just for girls, and we think anyone will get a buzz playing high-octane slots like Hot Coin, Reels & Wheels, and 777 Vegas, all of which offer rapid-fire action.
For those who prefer story-led games, the likes of Buffalo Wild, Gold Nugget Rush, and Ultimate Dragon Inferno should appeal, while games aimed directly at women with strong female characters include Piggy Game and Amazing Bass, where this time around, you play along with a fisherwoman.
New games are regularly added, helping Queen Bee Casino keep up with the times, while a slew of exclusive slots and Bonus Buy slots are available, too.
Bonuses and promotions: 4.8/5
Queen Bee Casino’s welcome bonus is a matched deposit worth up to $5,000. It also comes with 200 free spins, but the terms and conditions can be a tad confusing, which is why it’s important to read them clearly before you make a first deposit.
For example, while the minimum deposit is $20 for the matched offer, it’s $100 for 100 free spins, and $200 if you want to claim all 200 free spins. There are also three different bonus codes you can apply, with each one giving you access to a different match percentage.
Once you’ve claimed the offer and you’re up and running, you’ll then find a raft of regular bonuses here. These include weekly free spins, 15% weekly cashback, and a referral bonus. You can also claim a weekly reload bonus, although the minimum deposit is set at $50.
Payment methods: 4.7/5
Credit and debit cards like Mastercard come with a reasonable $25 minimum deposit, while crypto has an even lower $20 min deposit. You can also fund your account with P2P, but a $100 minimum deposit is in place.
For withdrawals, cryptocurrencies have a $20 minimum withdrawal, but you won’t be able to use your card. Instead, you can withdraw fiat currencies with P2P, which has a $50 minimum withdrawal, or money orders, bank transfer, or bank check.
The last 3 have high minimum withdrawals, though it has to be said that payouts here are always processed diligently and quickly.
User experience: 4.8/5
With the queen bee avatars and the electric pink colours, Queen Bee Casino certainly stands out as a vibrant slots site. However, it’s equally as functional, and we love how laid-back and well-laid out this casino site is.
Examples include how Queen Bee Casino has created a wide range of categories for their slot games, such as ‘Bonus Eligible Games,’ which makes them easy to find. A separate section for the highest payout online slots would have been the cherry on the icing — but we can’t have everything.
For customer support, you can visit the in-depth Help Centre or contact the team via 24/7 live chat and email.
5. Super Slots (Guns & Dragons) – Best for new slots with highest RTP
Pros:
- 300 free spins for new players
- 1,200+ online slots
- New games added frequently
- Over 20 payment methods
- Instant VIP access
Cons:
- Limited non-crypto withdrawal methods
- Only free spins in welcome bonus
If ever there’s a casino site that’s constantly updating its roster with hot new releases, it’s Super Slots. You can play more than 1,200 games in total and get access to brand new high RTP slots that are stacked with innovative features and gameplay.
Gameplay: 4.75/5
The whole gaming experience at Super Slots is electric, whether you prefer to stick to old-school classics reminiscent of retro arcade games or play the latest titles that have highly developed themes and stories.
Whatever you decide to play, online slots such as Guns & Dragons, Bison Horizon, and Gorgon’s Stash have huge payout potential. Other slot games that caught our eye include the Temple of Clusters (not for the faint-hearted!) and Boss Rush, which is perfect for anime fans.
Wild Girls West, meanwhile, is a feminist take on wild west games, while Take the Bank is a simple, straightforward slot game with a 96.08% RTP where the rules are ever so simple: You need to … take the bank!
Bonuses and promotions: 4.5/5
It’s hard to argue with the 300 free spins that are up for grabs at Super Slots, although this online casino recently decided to ditch its matched deposit welcome bonus altogether.
The free spins will be added to your account the day after you’ve made your first deposit in doses of 30 per day, each on a different slot, giving you plenty of games to explore.
The best way to get the biggest bonuses at Super Slots is through the VIP program, which you get instant access to once you join.
You can also enter cash races each day, play the ‘Super Slot of the Week’ for the chance to win additional bonuses, and claim 100 free spins each Thursday. However, to claim this latter offer, you must stake at least $1,500 on the previous Wednesday.
Payment methods: 4.75/5
Like a lot of the top online slots sites, Super Slots has made credit and debit cards available for deposits but not for withdrawals. This can be a tad frustrating, especially when you consider P2P has the lowest min withdrawal limit for regular payment methods, but even that is set at $50.
Making a deposit is a breeze, though, and as one of the best crypto casinos, you can also play with over 15 digital currencies like Bitcoin, with all also available for withdrawals.
P2P payouts are completed quickly, as are crypto payouts, but you’ll be waiting longer if you use money orders, bank transfer, or check.
User experience: 4.75/5
Super Slots has a couple of sister sites, with which it shares the same basic shell. However, its purple, gold, and white colour scheme is enough to set it apart, while also elevating its aesthetics so that it feels pretty darn elegant.
Elegance is the way we’d describe the overall UX — the buttons work perfectly on all devices, the games load quickly, and the menus are clearly labelled, ensuring site navigation is a dream.
It’s a shame there’s no phone support, but comprehensive FAQ pages and a Help Centre should fill in most gaps. If not, you can contact the team via live chat or email.

Best RTP slot machines: FAQs
Why does RTP matter in slot games?
RTP stands for ‘Return to Player’, and it matters because it lets you know what your chances of success are when you play any online slot machine.
For example, if a slot machine has a 96% RTP, it means that it pays out $0.96 for every $1 wagered. If you were to play a 97% RTP slot machine, you’d have an even better chance of winning, and the same goes if you played a 98% RTP slot machine.
How do I find the highest RTP online slots?
A general rule of thumb you can apply is that 96% RTP is usually considered to be ‘average’ when it comes to RTP. Any slot machine that has a 96%+ RTP is therefore a high RTP slot machine, and these games are available at all the top casino sites.
Can I win real money playing the highest RTP slot machines?
While you can win real money when you play the highest RTP slot machines, success isn’t guaranteed. RTP percentages should act as a guide, helping you to decide which top slots to play — but it’s essential that you don’t consider it a given that you will win.
The most important thing is that you also focus on things like a game’s existing features and treat playing slots as a source of fun and entertainment first and foremost. High RTP slots tend to pay out more often over time, but it’s important to play for enjoyment, not just to chase potential returns that aren’t guaranteed.
What types of online slots are there?
There are lots of different online slots you can play at casino sites, including the traditional three and five-reel online slot, multi-reel slots, and progressive jackpots, where the potential win increases each time a player spins but doesn’t win.
You can also play 3D slots at some sites, as well as experiment with branded slots, Megaways slots, bonus buys slots, Drop & Wins, and more.
Can I stream myself playing online slots for real money?
Streaming is popular with gamers who use Twitch to share their real-time experiences with their fans and supporters. And while you can do this when playing high RTP slots too, you’ll need to double-check the casino’s T&Cs.
Does volatility matter in high RTP slot games?
Volatility matters because it can help to determine your chances of winning. High volatility slots pay out less frequently than low volatility slots, but the attraction lies in their risk factor, as well as the huge, explosive wins that are up for grabs.
What is the best casino for high RTP slots?
You’ll find the highest RTP online slots over at Ignition, a reputable casino site with more than 400 games and regular bonuses. You can claim a $3,000 welcome offer to get started and play a mix of classic slots, new slots, and progressive jackpots, either on desktop or your mobile device.
Winning strategies for playing online slots with high RTPs
Playing the best payout online slots is about more than just spinning a few reels. Believe it or not, there is a bit of skill and discipline involved, and you can develop good habits by leaning back on what works for you when you’re playing video games.
Here’s what our experts have to say:
Play high RTP slots in demo mode first
Many real money online casinos let you play their high-paying slots in demo mode. The idea is similar to video gaming in that you get to ‘try before you buy.’ Instead of spending money, you can play for free to see if this is a slot game you actually want to play.
If you’re after quick access and minimal verification, no KYC casinos are a popular option for testing games in demo mode.
Play slot games with lots of bonus features
In the context of slots with highest RTP rates, bonus features are similar to power-ups in video games in that they let you ‘stay alive’ for longer.
The more bonus features a slot game has, the more chances (in theory) you have of winning.
Enter slots races
Slot races are available at many top-rated casino sites. They add a social dimension to online casino gaming, giving you the chance to compete against other players for cash prizes (as opposed to just competing against the algorithm).
The rules are simple, and usually you just have to spin the reels and climb the leaderboard.
Learn the rules, apply strategies
Each slot machine is different. There are all kinds of things to consider, such as which symbols you need to hit, the different combinations that could trigger a bonus game, and so on.
Just like you need a bit of time to get up to speed with the rules of a new video game you’re playing, you’ll find more success playing slots if you take some time to understand the way the game works.
Watch other streamers first
If you’ve found a slot you want to play, why not watch a video of someone walking you through it? There are all kinds of content like this available for free on the internet, and they can act as a guide for when it’s time to start playing with real money.
You’ll know what to do, mistakes to avoid, and you might even find it easier to work out a staking strategy.
Ready to play the highest payout online slots?
We’ve rounded up the best slot sites for winning real money. You’ll find a raft of the best payout online slots at each site, with many titles standing out for their high RTP rates, thrilling gameplay, and bonus features.
While each online casino has its own strengths, we’ve crowned Ignition as the best place to play slots, from classics to progressive jackpot games and beyond. You can sign up today and boost your bankroll with a $3,000 welcome bonus.
Whatever high RTP slot casino you decide to join, remember to stay safe online, gamble responsibly, and have fun!
