1. SuperSlots (Lost Mystery Chests) – Best Online Slots Site Overall

Pros:

• Over 300 games, including 250+ slots 
• 25 payment methods
• $6,000 welcome bonus for new players 
• Several slots-specific promotions
• Top-quality online slot machines by Betsoft

Cons: 

• Limited games on mobile

No matter how cliche its name sounds to you, SuperSlots is one amazing online casino, with some of the best slots you can find right now. You’ll enjoy Betsoft’s finest 5-reelers here — and that’s just the tip of the iceberg.

Slot Games: 4.8/5

With over 250 top-quality slot machines, SuperSlots is our top-rated online casino if you’re ready for some high-octane spinning sessions.

The bulk of the selection is 5-reel games with stunning graphics and visuals, followed by a rather limited range of old-school classic three-reels. Basically, anything you find here features high-quality graphics, which tells us the titles are carefully selected to help you avoid obscure slots.

Beyond that, there are several progressives with stunning jackpot pools to be won, and all games are provided by reputable game studios like Betsoft, Dragon, and Nucleus.

Editor’s choice: Lost Mystery Chests by Betsoft (95.37% RTP)

Welcome Bonus: 4.6/5

SuperSlots knows how to take care of its players. The welcome bonus package starts off with a 250% match deposit of up to $1,000. The next five deposits are a 100% match deposit of up to $1,000 for a total of $6,000.

Several other promotions include a 400% crypto bonus, 5% crypto boost, 10% weekly rebates, and some extra spins.

All of these are aimed toward slots, so if you’re looking forward to playing with some bonus money — you’ll rarely find more valuable bonuses at other slot sites.

Banking Options: 4.4/5

This is one of the top casino sites for banking options, with over 20 methods to choose from for deposits, including almost all the major credit cards, bank wire transfers, money order, and over 15 cryptocurrencies.

Withdrawals tend to take 24 to 48 hours to clear, which is slightly slower than the best Bitcoin casinos.

Variety of Casino Games: 4.7/5

With over 300 casino games on offer, SuperSlots has one of the most extensive online casino games libraries on our list. 

While the majority of those games are high-quality slots, players can also enjoy table games, video poker, specialty games, and even live dealers. 

Misc: 5/5

This online slots site features a rather simple design, with a purple background and white accent details. It’s quite easy to find your way around because of its intuitive design. One thing that does pop out, though, is the incredible graphics of the games — even on the thumbnails.

Join SuperSlots and take advantage of the whopping $6,000 welcome package.

2. Ignition (A Night With Cleo) – Best Progressive Slots of Any Slot Site

Pros: 

• Over a hundred highly popular slot games

Slot Games: 4.9/5

This online casino features over 120 real money slots, consisting of classic three-reel options and modern, cinematic five-reel video slots — but the main accent is definitely on progressive jackpot games.

Some ultra-popular progressive slots include A Night with Cleo, 10 Times Vegas, and Cyber Punk.

We know 120 slots doesn’t scream excitement — and you’d be right to think so, but all games are powered by over 13 providers, including top-dog developers like RTG and Betsoft, so you’re guaranteed enough styles and categories even though the selection is rather limited.

Editor’s choice: A Night With Cleo (Up to 92.5% RTP; progressive jackpot)

Welcome Bonus: 4.8/5

Ignition provides two combo welcome bonuses. When a player makes their first deposit using crypto, they receive a 150% match for up to $1,500 each for Ignition’s poker room and casino for a combined total of up to $3,000. 

For regular deposits, players can claim a 100% bonus for up to $1,000 each for their online poker and casino for a combined total of up to $2,000. 

As with all the best online casino bonuses and promotions, wagering requirements and terms apply. No codes are necessary to claim these offers; simply select your welcome bonus at the cashier during your first-ever deposit. 

Banking Options: 4.5/5

This online gambling site offers several convenient deposit methods to choose from, including Visa, Mastercard, American Express, Bitcoin, Bitcoin Cash, Ethereum, and several other cryptocurrencies. 

The payout time is well within industry standards and even quicker for crypto transactions, with a 24-hour processing timeframe.

Variety of Casino Games: 4.6/5

Nearly all legit online casinos will offer the three standard table games: blackjack, roulette, and baccarat.

This robust casino also offers eight video poker options, including “Joker Poker” and “10-Hand Jacks or Better.”

Misc: 5/5

Two key offerings really make this casino site shine above many others, beyond their slot game choices: the live poker room and live dealer games. 

For both tournaments and ring games alike, card players have a variety of Omaha and Texas Hold’em games to choose from, as well as Omaha Hi-Lo. Their poker tourneys consist of sit-and-go, turbo, satellite, GTD (guaranteed) tournaments, and much more.

Misc: 4.3/5

Cafe Casino sports a rather simple yet lively site design, dominated by white and orange accent colors over an indigo background. Site navigation is quite easy, although we did encounter some lag when checking the games. 

Its mobile compatibility is another story, though. We loved how smooth our experience was, not only when navigating the site but while playing slots for real money as well.

Red Dog has over 120 real money slot games to choose from, with popular titles like Achilles Deluxe, Caesar’s Empire, Asgard, Cash Bandits, and more. 

Players will enjoy not only incredible gameplay but the ultra-sharp graphics and exciting animations as well. It’s one of the things this casino is known for.

Related: Best Roulette Sites

Red Dog is known as a fully transparent casino site because it publishes both the monthly RTP percentage and the biggest win on all particular games.

Don’t be surprised if you see some games hovering above 100% because it’s the monthly value — not the exact number you can expect to get over a million spins, but it’s still quite close.

Editor’s choice: Bubble Bubble 3 (96% RTP)

Bonuses: 4.5/5

Red Dog offers some exclusive bonuses like the 260% match deposit bonus, which can be claimed when you use the bonus code MAXRED. This bonus only needs to be wagered 35x before you can claim any winnings. 

You can also claim a $40 no deposit bonus, and all you need to do is register for an account and use the bonus code FREERED.

Banking Options: 3.9/5

Banking is quite convenient at Red Dog, with 6 options for deposits. Players can fund their accounts using credit and debit cards, Flexepin, and 4 cryptos, including Bitcoin, Litecoin, Ethereum, and Tether.

Payouts are only available via bank wire, credit card, and Bitcoin, but you’ll need to have at least $150 in your casino balance before you can initiate a withdrawal.

Variety of Casino Games: 4/5

The majority of Red Dog casino’s library is composed of real money slots, but there are still some classic casino games to be enjoyed here. Poker enthusiasts, specifically, can enjoy over a dozen video poker games, including Loose Deuces, Double Bonus Poker, Aces and Eights, and more.

Red Dog publishes all of its games’ RTP values, which allows you to pick the games that would help you reach your wagering requirements. Free play mode is also available if you want to try out a particular game

Misc: 3.9/5

Live casino fans will be disappointed to know that there are very limited live dealer games offered at Red Dog. That said, there are enough slots for real money, poker, and other table games available to keep players entertained for hours on end.

Guide to the Best Online Slots Sites

Are Online Slots Rigged?

No, they’re not. If you play slots at licensed online casinos, you can rest assured that each outcome is genuinely random.

Because your safety is our top priority, we only listed online casinos that are secure and licensed. We made sure they implement the standard RNG testing methods that prevent any tampering with the games on hand.

What Are Progressive Jackpot Slots?

Progressives are jackpot slots where the total jackpot prize increases with each wager placed on a non-winning spin. Several slots may share the same progressive pool, which is why the amount of the jackpot rapidly increases. 

Once a player hits the jackpot, the size of the jackpot resets to a predetermined amount and continues to increase with each non-winning spin, constantly repeating the process. 

Where Can I Play Online Slots for Free?

Many online casinos today will allow you to spin the reels for free before spending any money. Both of our top-rated sites, Ignition Casino and Cafe, will allow you to test each game for free — even card games.

You can also claim Red Dog’s $40 no deposit bonus by entering the code FREERED to start playing for free with a chance to win some extra funds.

Which Is the Best Online Slot Game?

We can’t really give you a universal answer to this question since it’s a matter of personal choice. What we can do is give you multiple recommendations based on the slot game category.

If you seek huge jackpots above all, we suggest you play Shopping Spree (available at Ignition). If you’re all about high-quality visuals, virtually any game by Betsoft will do, but we recommend Stay Frosty (available at SuperSlots).

If old-school classics bring some (un)fortunate memories, you may want to look into Caesar’s Empire (available at Slots.lv).
