Best Online Slots for Real Money: Online Slot Sites with High RTP Machines in 2023

No matter if you’re chasing progressive jackpots, looking for exciting graphics and bonus round features, or want to find the highest RTP games, we’re sure you’ll agree with us:

Playing slots online is a whole lot of fun.

But before you put real money on the line, hear us out: We’ve rounded up the most reliable online casinos with the best online slots in the business.

Ignition Casino outshines its competitors with its rewarding welcome bonus, low wagering requirements, and super fast payouts. The rest of our recommended slots sites gave it a good run for its money, though.

Let’s check them all out!

Best Online Slots

1. Ignition Casino (777 Deluxe) — Best Online Slots Site Overall



  • Hot-Drop Jackpot slots

  • Up to $3,000 welcome bonus

  • Fast withdrawals within 24 hours

  • Relatively low wagering requirements

  • Unrivaled player support


  • No e-wallet payments

This is an awesome casino to play progressive slots and regular online slots with high RTPs. Withdrawals are super fast, and the level of player support is unmatched.

That being said, ranking Ignition at #1 was a natural decision.

Online Slots: 5/5

Ignition is home to 100+ premium slots, 35 of which feature progressive jackpots. The beauty of playing these progressive jackpot slots is that there are usually several of them with jackpots well over $200K.

The top slot here, in our opinion, is “777 Deluxe” — a 10-payline fruit machine with added features, a progressive jackpot, and an impressive RTP of 96.13%.

The fact that this progressive slot only has 10 paylines means that you don’t have to break the bank to play it, even though you may win a huge sum of money.

“777 Deluxe” also falls under Ignition’s ‘Hot Drop Jackpots’ collection — a handful of slots that feature three additional progressive jackpots: an hourly jackpot, a daily jackpot, and a jackpot that must be won before it reaches $250K.

The benefit of playing these ‘Hot Drop Jackpot’ slots is that you can check when one of the jackpots is ready to drop. Perfect for the superstitious type.

Welcome Bonus: 5/5

Ignition offers separate welcome packages for fiat and cryptocurrency players.

If you deposit with fiat, you’ll get a casino bonus of 100% up to $1,000 and a poker bonus of 100% up to $1,000. Use the code “IGWPCB100” when you make your first deposit to claim your 100% deposit match.

Crypto players get a 150% casino welcome bonus up to $1,500 and a poker bonus of 150% up to $1,500. Enter code “IGWPCB150” when you deposit to claim your 150% match bonus.

You must deposit at least $20 to claim the offer. The wagering requirement on the casino bonus is 25x the bonus plus the deposit amount — which is pretty fair compared to other online slot casinos.

If you’re not into poker, you don’t have to pay too much attention to the poker portion of the welcome bonus. However, it will automatically be on your account if you do wish to unlock it by hitting the poker tables.

Deposits & Withdrawals: 4.8/5

Ignition boasts rapid cashout times of fewer than 24 hours, but the time it takes for your withdrawal to reach you will depend on the method of payment that you’re using.

The casino accepts Visa, Mastercard, AMEX, Bitcoin, Bitcoin Cash, Litecoin, and Ethereum. You can also use Vouchers, which can be bought or gifted from other players at Ignition.

Customer Support: 5/5

You’ll never be left hanging at Ignition, thanks to the numerous customer support channels available.

Live chat support is available 24/7, and there’s a useful forum where active community members discuss various topics.

There’s an elaborate Help Center that covers just about every question, or you can fill in the online contact form, and a support agent will get back to you.

Misc: 5/5

This casino is not only a slot-lovers paradise; it’s considered one of the best online poker sites in the world. It receives the highest poker traffic from a mix of professional and regular poker players.

There’s no type of casino game that you can’t play here. It boasts 34 live dealer games, 7 bingo games, plenty of automated table games, and virtual sports.

  • 240% Slots bonus + 40 free spins

  • Monthly RTP reports

  • RealTime Gaming slots

  • Live chat deposit support


  • E-wallets not supported

This is one of the few sites that publishes monthly RTP reports for its online casino games. It offers new players a generous welcome bonus and supplies existing players with an endless stream of lucrative slot bonuses.

Online Slots: 4.8/5

Red Dog Casino hosts 119 online slot machines created by ‘RealTime Gaming’ — a pioneer in the online gambling sphere.

One of the top slot games here is “Gem Strike,” a feature-rich video slot with 25 paylines that can pay out up to 50,000x your bet.

The slot machine has an ‘official’ RTP of 96%, but you can check the up-to-date RTP stats of the slot on the Red Dog Casino site.

The casino posts monthly RTP reports that show the real win rate on all the online slots for the month. The reports have filter buttons that you can use to sort the slots according to various parameters, making them great for finding slots with high RTPs.

Welcome Bonus: 4.8/5

If you’re new to Red Dog, you can claim a 240% match bonus on your first deposit plus 40 free spins on the “Spring Wilds” slot machine.

The minimum deposit to claim the welcome offer is $10 if you’re using Neosurf, $20 for cryptocurrency deposits or Flexepin, and $30 for credit card deposits.

3. Super Slots (Take the Bank) — Biggest Welcome Bonus for Online Slots



  • Up to a $6,000 welcome bonus

  • 250+ Video slots

  • Wide variety of payment methods

  • Cashouts within 48 hours


  • Limited variety of jackpots

Super Slots piqued our interest with its welcome bonus of up to $6,000 that you can use on slots — but made us stay with its unmatched collection of top-quality online slots by Betsoft.

Online Slots: 4.6/5

Super Slots’ electrifying slots portfolio consists of hundreds of top-rated video slots from six innovative game providers, including Betsoft Gaming, Nucleus, and Dragon.

One of Betsoft’s best-performing slot machines, “Take the Bank,” is a fast-paced slot with an RTP of 96.08% that will keep you on the edge of your seat.

This real money slot has 75 paylines and is loaded with bonus features, including free spins, random wild symbols, scatter symbols, and the always-popular ‘symbols collection’ feature.

But there’s plenty more fun to be had here. This online slot lobby is jam-packed with thrilling 5-reel video slots and a decent selection of classic fruit slot games that will keep you entertained for hours on end.

Our only gripe is that jackpot slots are pretty hard to locate unless you know them by name.

Welcome Bonus: 4.9/5

The fiat welcome offer at Super Slots is a 250% match bonus up to $1,000 on the first deposit . You must use the bonus code “SS250” when you deposit to claim this offer.

Of course, the action doesn’t stop there. Once you’ve claimed the first deposit offer, you can claim a 100% bonus of up to $1,000 on your next 5 deposits when using the bonus code “SS100”. That makes the total fiat welcome bonus a whopping $6,000!

A minimum deposit of $20 is required to be eligible for the welcome bonuses — and don’t forget to use the bonus codes when you deposit.

Crypto users can claim a 400% first deposit bonus of up to $4,000. This bonus turns a $1,000 deposit into $5,000 to play with — and that’s pretty bloody impressive. The bonus has a wagering requirement of 48x, however. You can’t have it all.

Deposits & Withdrawals: 4.8/5

Super Slots processes withdrawals within 48 hours but strives to release same-day payouts as much as possible.

This slot site provides an excellent variety of payment methods. To fund your account, you can use any of the 17 deposit methods offered, which include all the popular cards as well as Money Gram, Person to Person, and cryptocurrencies.

There are 8 withdrawal methods available — 6 cryptocurrencies, checks, and bank wire. If you deposit with crypto, you can withdraw the same way. If you use one of the other deposit methods, you will receive your cashout via bank wire or check.

Customer Support: 5/5

The customer support team at Super Slots is available 24/7 on live chat. The Chat Hosts are skilled and capable of walking you through the deposit process regardless of the method you’re using.

  • Up to 5 BTC plus 200 free spins

BitStarz is an award-winning online casino with a massive portfolio of online slot games. It’s also the online casino with the most diverse collection, hosting real money slots from more than 40 different providers.

Online Slots: 5/5

This is the best online slots site for crypto players — housing 1,000+ slot games from legendary providers like Endorphina, Northern Lights, Platipus, True Lab, and Yggdrasil.

If you decide to play at BitStarz, don’t pass up the opportunity to play “Elvis Frog in Vegas,” created by BGaming. The slot game has been a sensation since it hit the gambling scene in 2020.

This slot machine offers 25 paylines and an RTP of 96%. It incorporates a range of bonus features such as free spins, blazing reels, and a coin respin feature that can award three unique jackpots: a mini jackpot, a major jackpot, and a mega jackpot.

There are heaps of high-paying online slot machines worth playing at BitStarz, so you’ll never have to play slots online anywhere else.

Welcome Bonus: 4.5/5

If you’re new to BitStarz, you’re eligible for a total welcome package of 5 BTC plus 200 free spins . The welcome pack is split over the first 4 deposits like this:

  • No deposit bonus: Get 20 free spins as soon as you verify your email

  • Deposit 1: 100% up to 1 BTC + 180 free spins

  • Deposit 2: 50% up to 1 BTC

  • Deposit 3: 50% up to 2 BTC

  • Deposit 4: 100% up to 1 BTC

A minimum deposit of 20 USDT or 0.0008 BTC is required to claim the welcome bonus and 40x wagering requirements apply to the bonus. The 180 free spins that come with your first deposit are added over 9 days at a rate of 20 per day.

You’ll also have an opportunity to claim 20 no-deposit free spins when you sign up. If you can’t find the spins, contact customer support on live chat. Be sure to do this quickly since the spins expire after 24 hours.

As we said, the welcome package carries 40x wagering requirements and expires within 7 days. Indeed, Bitstarz would receive the perfect score if it gave you 30 days to play through your bonus funds.

Misc: 4/5

Unfortunately for fiat players, this is a crypto-only casino in most countries across the world. The casino supports numerous cryptocurrencies. You can deposit as many different cryptocurrencies as you want and toggle between them.

When you’re on a specific cryptocurrency, you’ll only be shown slot machines that are compatible with that crypto, so you’ll never open a slot game only to find that you can’t play it — which is a nice touch.

Finding the Best Real Money Slots Sites

Below are the criteria we applied when ranking the best online slot sites — you can use the very same benchmarks to find a decent slot casino on your own.

Online Slots:

When you’re playing online slots for real money, you need to be sure that the gambling site has a decent portfolio of slot machines. The slots should be developed by reliable game providers, and they should have RTPs and other features that meet industry standards.

Welcome Bonus:

The best slot casino sites offer welcome bonuses that can be used to play real money online slots. The bonuses should have lower wagering requirements that can be met while playing slots. Other terms of the welcome bonus, such as time restrictions and win limits, should also be reasonable.

Deposits and Withdrawals:

When you’re playing at slots for real money, your deposits and withdrawals need to be secure. Ideally, withdrawals should be paid out quickly to prevent you from playing your winnings back on the real money slots. Look for top online casinos that support your preferred payment methods.

Customer Support:

There are few things more annoying than when you’re playing slots at online casinos and run into issues that can’t be resolved because customer support is lacking. It’s important to stick to online casinos that offer good support with knowledgeable staff. It’s best when support is available 24/7.

Other Considerations:

There are many other things to think about when choosing online casinos. You might want to look at the other games available, the types of promotions offered, and whether or not the online slots casino is compatible with your mobile device.

Guide to Playing Real Money Online Slots

Can You Win Real Money Playing Slots Online?

Yes, if you’re playing at legitimate real money slot sites, you can indeed win money. Some real money slots sites allow you to play slots in ‘demo’ or ‘free’ mode. If you want to win real money, make sure that you’re not playing free slots — also known as ‘practice play.’

Are Online Slots Rigged?

Real money slots at reliable online casinos are not rigged. Reliable online casinos host slots from trusted providers. The outcomes of the slots are determined by random number generators to ensure that the results are completely random.

What is the RTP of an Online Slot?

The RTP of a slot game is the ‘payout percentage’ or the ‘return to player percentage.’ It’s the percentage of money players bet that the slot machine is theoretically supposed to pay back to players in the long run.

How Do I Choose the Best Online Slots Site for Me?

The best online slot site for you depends on your preferences when you play online slot machines. Look at the ‘Best for’ categories for the top online casinos recommended here. If you seek big jackpots, try Slots.lv , and if you want a big welcome bonus to play slots — sign up at Super Slots .

Ignition is the best slots casino overall, so if you’re unsure, starting at Ignition is a good idea.

Where Do I Find Real Money Online Slots that Win the Most?

Finding the online slot game that ‘wins’ the most would be nearly impossible.

Online slots with high payout percentages are supposed to pay out more often than those with lower payout percentages, but those figures apply in the long run. A slot would have to be played millions of times before it aligned with its ‘stated’ payout percentage.

Which Real Money Slots Apps are the Best?

The online casinos that we recommend are all fully optimized for mobile devices and are the best real money slots apps, in our opinion. These online casino apps offer high-quality real money slots, they provide top-notch customer service, and they really do pay players their winnings.
