That said, our 17 top-reviewed picks offer players an easy-earn welcome bonus, tons of betting options, a long list of secure payment methods, and best-in-class customer support.

Best Online Slots

1. Slots Empire (Cash Bandits 3) – Best Online Slots Overall

  • 55 free spins with first deposit
  • Reasonable 35x playthrough 
  • 253 traditional casino games

  • High credit card deposit minimum

Slots Empire is our top-reviewed online slots casino overall. When you sign up, you can take advantage of their 245% deposit match up to $3,000, enjoy 55 free spins on Caesar’s Empire, and spin through 208 high-quality online slot games at your leisure. 

Gaming Variety: 4.7/5

Slots Empire hosts 253 exclusive casino games that spread across 208 online slots and 50+ table games. Because their online slots library boasts an average RTP of 97%, the odds are (mostly) in your favor here. 

One of our favorite online slots for real money from their library was Lucha Libre 2. This multi-payline, five-reel slot carries an RTP of 97.5% and resembles what you’d expect to see from a cartoonish Mexican wrestling match. 

With a maximal payout of 50,000x your wager, jackpot hunters shouldn’t be disappointed. 

Slots Empire also hosts 14 video poker games, 10 versions of online blackjack, 5 virtual roulette wheels, and keno. You’ll even find 5 games of live dealer poker to enjoy in between spins. 

Bonuses & Promos: 4.7/5

When you use the promo code “IRONBORDERS”, you can take advantage of a 245% deposit match up to $3,000 and 55 free spins to use on Caesar’s Empire (95% RTP).

We also fell in love with their 24/7 reload bonus, which is redeemable every time you add money to your casino wallet. You can receive a 100% match when you reload $30, a 120% match when you deposit $75, and a 150% match when you put down $150. 

It’s rare to find reload bonuses that extend past your first few deposits, but we were glad to see Slots Empire does things differently. 

Banking Options: 4.5/5

Players who sign up with Slots Empire can utilize 8 secure payment methods through their site. 

You can make your deposits here through Visa/MasterCard credit card, Neosurf, BPay, PayID, bank transfer payment, Bitcoin, and Ethereum. 

While their banking menu appears limited at first glance, we were glad to see them focus on accepting a little bit of everything. 

The only thing we didn’t like here were their high credit card deposit minimums. In order to qualify for your bonus match, you’ll need to deposit $30 through Visa/MasterCard, the equivalent of $20 through BTC/ETH, or $10 via Neosurf. 

Crypto payments are fee-free and instant; while all fiat payouts take anywhere from 1-3 days to process and deliver. 

Customer Support: 5/5

In accordance with industry standards, Slots Empire offers 24/7 live chat, email, and phone assistance for players with questions and concerns. 

They also respond quickly across the board, which we sincerely appreciated. Sending them a live chat request got us a response from a real person within 5 minutes, while they took a mere 12 hours to email us back. 

Calling their phone line wasn’t a frustrating experience, either – we waited on hold for less than 20 minutes before speaking to one of their representatives.

Additionally, we liked their weekly reload bonus. Every Wednesday, you can enjoy a 50% match up to $250 when you pad your casino wallet. 

That said, you’ll want to watch out for their initial crypto deposit match. While you can take advantage of a 400% initial welcome bonus up to $4,000, you’ll have to contend with a 48x playthrough to cash out.

That said, you’ll need to deposit a minimum of $50 via credit card to qualify for their $6,000 welcome bonus. Thankfully, crypto players will only need to deposit the equivalent of $20 to play here. 

As we’d expect, crypto withdrawals are fee-free and instant. However, their 48-hour fiat withdrawals come attached to a 3% fee for wire transfers and courier checks. 

Customer Support: 4.6/5 

We were glad to see Super Slots offering 24/7 live chat, email, and phone assistance for players to take advantage of. 

We were also relieved to see them respond quickly to our inquiries. They took a bit less than 24 hours to respond to our email, and we waited on hold for approximately 30 minutes before speaking with a real person on the other line. 

That said, if you have immediate concerns, you should use their live chat feature. We got a message back within 10 minutes of sending them a request to chat.

We appreciated their low deposit limits – you’ll only need to put down $20 in fiat or $10 in crypto for each of your first 9 deposits to qualify for your bonus match.

However, in addition to wishing they’d accept a few more e-wallets, we wish they’d eliminate their high fiat withdrawal fees. 

As it stands, payouts made through courier check will cost you $75 each. Any additional debit card withdrawals after your first per month will cost you $50 of your winnings. 

On the bright side, crypto payouts are instantly processed and fee-free. If you want to avoid steep fees, you should invest in some Bitcoin before you make an account with

Players who sign up with Ignition can enjoy an ample selection of casino games that span over virtually every betting market. 

On their site, you’ll find 56 slot machines that carry an average RTP of 96%. Although this doesn’t sound like much, avid online slots enjoyers will be happy to know that many of Ignition’s slot machine games are exclusive to their site — and there are free slots available as well.

  • 135 real money slot games
  • 12 live casino games
  • 200% initial bonus match up to $1,000
  • Reasonable 30x playthrough 


  • Limited fiat banking menu 
  • Slow fiat payouts 

Big Spin Casino is our top-reviewed selection for their seamless mobile compatibility. Although you’ll have to enjoy their 135 slot games and 12 live dealer games from your web browser, we were surprised to encounter minimal issues playing throughout their entire online casino library. 

Gaming Variety: 4/5

As you might expect from their name, Big Spin Casino offers players a very slots-centric library. 

However, they put an ample amount of work into hosting approximately 50 table games for players to enjoy in between spins.  

You’ll find 135 exclusive, Betsoft-backed 3D slot games that include more popular and lesser-known titles. One of our favorite slot games from their library is Mystic Hive

This 5-reel slot offers 30 paylines, and boasts a maximum payout of 243x your original wager. Beekeepers will enjoy this honeycomb-themed reel, but we think there’s room for everyone when a 96.13% RTP is on the line. 

Additionally, you’ll find 12 live dealer games here, alongside 22 online blackjack games, baccarat, several video poker variants, and roulette. 

The best part about Big Spin Casino is that their entire gaming library is optimized for on-the-go wagering. It’s rare to find an online casino that can honestly say every game in their library works well on mobile devices, but Big Spin Casino takes the cake here. 

Bonuses & Promos: 4.4/5

When you make your first deposit with Big Spin Casino today, you can receive a 200% initial match up to $1,000 using the promo code “BIGSPIN200”. 

Again, while this match cap might not make online gamblers salivate, it comes attached to a reasonable 30x playthrough. You shouldn’t have to work against impossible odds to cash out here. 

This bonus is valid for cash and crypto players. It’s nice to encounter an online casino that doesn’t favor crypto bettors to the point of driving fiat players away with insanely high playthroughs. 

Banking Options: 4/5

Players who sign up with Big Spin Casino can take advantage of 8 secure payment options; although 5 of them are cryptocurrencies. 

You can make your deposits here through credit card, money order, BTC, Bitcoin Cash, Litecoin, Ethereum, and Ripple. 

We didn’t like their high fiat deposit minimums. You’ll need to deposit $45 via credit card or $100 via MoneyGram in order to qualify for your bonus match. 

Additionally, while crypto payouts are instantly delivered, you’ll have to wait up to 5 days for wire transfer payouts to process. 

Customer Support: 4.5/5

Big Spin Casino offers 24/7 live chat, email, and phone assistance for players. 

Upon sending them a live chat request, we received a response within 5 minutes. However, we didn’t like that players can only access their live chat feature after they’ve made their first deposit. 

If you choose to send them an email, you’ll have to wait 48 hours for a response from their team.

Guide to Playing Online Slots for Real Money

Are Online Slots Rigged Against Me? 

Nope. No matter what you hear on the internet, online casino slots for real money carry the same odds as any slot machine you’d find at your favorite in-person casino. 

That said, you need to sign up with a licensed online casino to make sure you’re dealing with regulated slot games and fair betting odds. All of the sites we list here are licensed and regularly audited for fairness. 

Randomized number generators (RNGs) ensure that each spin you bet money on carries a randomized outcome, just like physical slot machines. Online slot machines that list a high RTP (return-to-player) percentage put anywhere from 94-98% of money wagered back into players’ pockets. 

Are Online Slot Sites Trustworthy? 

Even though most online slot casinos are reliable, there are a few bad apples that spoil the bunch. Namely, unlicensed online casinos aren’t regulated.

Making the mistake of signing up with an unlicensed online casino puts your personal information and financial integrity at risk. 

All of the online casinos we review are fully licensed to operate – you can expect randomized slot games, timely payouts, and reliable customer support from any site we endorse.

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

Finding the best online slots casino for you is akin to enjoying your favorite pastry from a bakery. Mostly everything inside the bakery is good, but only a few delicious treats hit the spot. You’ll need to make your final decision based upon what you’re primarily trying to find. 

We have some suggestions for the indecisive.
