1. Red Dog (Copy Cat Fortune) – Best Slots Site Overall
Pros:
- No deposit free spins bonus
- 225% slots welcome bonus
- Good variety of casino games and live dealers
- Fun and unique specialty games
- Zero fees on any transaction
- All slot games are free to play
Cons:
- Some games are only available in the Windows app
Debuting in 2019, Red Dog is one of the newest online casinos to offer slots for real money. Considering the heavy focus on slots players with a no deposit bonus and a super-generous slots welcome bonus — it was no surprise that Red Dog topped our list.
Slot Games: 4.7/5
Red Dog offers just about 120 slot game titles. Though this is not the highest number of real money slots online compared to other real money online casinos, their selection includes ultra-popular video slots and dozens of progressive jackpots.
The online slot machines category is well-organized by reel type, including three, five, and six-reel slot games. This makes it easier for players to choose the type of real money slots they are in the mood to play.
Perhaps the essential feature is that all real money slot games are available to test for free. This approach allows new players to test the waters and see what they like before depositing.
Our favorite game here was Copy Cat Fortune (we like cats; can’t help it), and we’re pretty sure you’ll enjoy “hunting” the fish, parrot, and mouse symbols together with the cat.
Casino Games: 5/5
Like their slot game section, Red Dog Casino seems to put quality above quantity when it comes to other games in their casino.
They offer all the major table games that players enjoy — blackjack, roulette, and baccarat — and some unique titles, as well. They also have over a dozen options to choose from for video poker.
Welcome Bonus: 4.8/5
Unlike their games, this real money slot casino goes for both quality and quantity when it comes to its welcome bonus package.
First off, new players can claim 30 free spins just by entering the FREEBANDITS code; no deposit is required.
Then, new players can enter the code WAGGINGTAILS for a generous 225% slots bonus of up to $12,250 across the first five deposits.
Each of the first five deposits is capped at $2,450, allowing you to potentially net up to $12,500. The wagering requirements are 35x, and you’ll even get 20% extra for Neosurf or Bitcoin deposits.
Banking: 4.5/5
Red Dog offers all the major deposit methods, including most credit cards, Bitcoin, Litecoin, Ethereum, and other crypto options.
For payouts, players only have three options to choose from, and while having more would be great, they still cover the bases with bank wire transfers, cryptocurrencies, and the rare option that most online slots casinos do not offer — credit cards.
There are zero fees for both deposits and payouts, but the minimum withdrawal is $150.
Misc: 5/5
This casino offers variants of blackjack, roulette, and Super 6 (non-commission baccarat) for their live dealer games, giving players plenty of options for that real-life casino feel.
Their specialty games include keno, shooter games, and board games, and if players download the software client for Windows, they get even more specialties.

2. Ignition (777 Deluxe) – Best Range of Progressive Jackpots of all Slot Sites
Pros:
- Great selection of progressive slots
- Valuable $1,500 casino welcome bonus
- 20+ high-quality table games
- Over 30 live dealers
- Renowned live poker room featuring high-GTD tournaments
Cons:
- Could have more classic slots
Ever since its launch in 2016, Ignition has remained one of the most popular online casinos for progressive slots, live poker, and live dealer games.
Slot Games: 4.5/5
Ignition’s real money slots library includes classic three-reel and modern five-reel video slot games, with dozens of progressive jackpots to enjoy.
Some real money slots sites offer thousands of games for real money, but many of the titles are often generic or unbranded. Ignition’s 120+ real money slots primarily consist of popular branded titles, including their large selection of slots with progressive jackpots.
Many of their progressives get deep into the six-figures, and a few online slots, like Shopping Spree, have reached a progressive jackpot of over $5 million. So, this may be the place for you if you want a shot at whopping jackpot prizes.
Since we didn’t feel that lucky, our favorite game here was 777 Deluxe — a classic-style progressive jackpot with a slightly modern touch that hovers around the $50k jackpot mark.
Casino Games: 4.6/5
This casino site offers a solid selection of all the standard table games, but their unique titles really stand out; these games include the rare Andar Bahar, Teen Patti, craps, and table poker games with progressive jackpots.
Welcome Bonus: 4.5/5
As a real money slots online player, you can enjoy Ignition’s 150% up to a $1,500 crypto bonus that you can spend on all real money slots (excluding progressives). There’s also an additional 150% up to $1,500 for poker, which brings the total value to $3,000 and 25 free spins on Fast & Sexy.
The casino bonus comes with a rollover of 25x, which is the lowest on our list of the best real money slots sites.
Other than that, there’s a welcome bonus of 100% up to $1,000 that you can claim when depositing via credit cards. Once you become an active member, you can claim a 100% up to $100 match bonus or a 100% up to $1,000 for crypto once a week (The Weekly Boost).
Banking: 4.8
This casino site offers nearly every major credit card for deposits, in addition to Bitcoin, Ethereum, and several other cryptocurrencies.
For payouts, players can select wire transfer, check by courier, Litecoin, Bitcoin Cash, and Bitcoin. When Bitcoin is used for withdrawals, payouts are delivered in less than 24 hours.
Misc: 5/5
This online casino holds one of the most famous online poker rooms, providing variants of Texas Hold’em and Omaha for both ring games and tournaments alike.
Card players can indulge in lucrative GTD (guaranteed prize pool) tournaments, including sit-and-go, turbo, and their “Monthly Milly” tournament with a GTD of a stunning $1 million.
Beyond that, Ignition provides over 30 live dealer games, with 26 dedicated to various types of blackjack, so finding a seat at one of the most popular live table games is rarely a problem.
3. Cafe Casino (Animal Wilds) – Best Real Money Online Slots Site for Free Games
Pros:
- All games are available for free
- Excellent 350% welcome bonus
- Good range of banking options and quick payouts
- 30+ jackpot slots
- High-quality specialty games, including “ThunderCrash”
Cons:
- Slim range of live dealer games
With a clean, user-friendly design and modern feel, this real money online slots casino provides an exceptional gambling experience — especially for new players.
Slot Games: 4.5/5
The excellent online slot machines at Cafe Casino are supplied by innovative software providers, including RealTime Gaming, Rival, and Genesis Gaming.
Similar to Ignition, the focus at Cafe Casino is quality, which means that all 120+ slot machines are high-quality, handpicked titles from 7 leading game developers.
Besides real money slots, Cafe Casino will allow you to test all other games for free, which goes a long way to show how much the casino cares for players without prior gambling experience. There are even small guides you can read when you open each game to learn how it works.
Casino Games: 4.6/5
This online casino provides dozens of table games like blackjack, poker, baccarat, craps, and roulette. They also have unique options, like Teen Patti Turbo and color-wheel and jackpot games.
Players can also enjoy a solid selection of video poker games, including several titles that offer up to 10 hands at one time.
Welcome Bonus: 4.6/5
New players can score a deposit bonus worth 350% up to $2,500 when making their first-ever deposit using crypto. This is one of the best casino bonuses you can claim on our list of slot sites.
The wagering requirement for this bonus is 40x, which is definitely a little steep but still worth it, considering the massive match rate of 350%.
If you’re not a crypto user, you’ll still get to claim a welcome bonus that you can use on slots, but at a lower match rate of 250% and a maximum of $1,500.
Banking: 4.5/5
Players have a handful of convenient options to choose from for both deposits and withdrawals at Cafe.
For deposits, they accept Bitcoin, Bitcoin Cash, Ethereum, select Visa gift cards (a rarity), and most major credit cards.
For withdrawals, players can choose Bitcoin, Bitcoin SV, Ethereum, wire transfer, and two other options that deliver winnings within an hour: Bitcoin Cash and Litecoin.
Misc: 4.7/5
This online casino offers six tables with live dealers, consisting of one Super 6, one standard baccarat, two blackjack options, and two roulette tables.
Their specialties include several bingo and keno games, as well as the top-rated arcade-like shooter game, “ThunderCrash,” where players can win up to $100,000.
4. BetUS (Stay Frosty) – Best Betsoft Slots Selection of all Online Slots Sites
Pros:
- Great selection of top-quality Betsoft slots
- Active since 1994
- Over 30 table games
- 10+ live casino games, including Auto Roulette
Cons:
- Few specialty games
- Parts of the online casino are cluttered and need organizing
BetUS has been a go-to sports betting platform since 1994, and it shouldn’t confuse you that we ranked it among the best online casinos for real money slots — the range of Betsoft titles on hand is the best you can find.
Slot Games: 4/5
The number of slot machine titles offered at this casino is solid, totaling over 200. While there are a few more slots from other providers, our eyes were set on Betsoft here.
We particularly enjoyed playing Stay Frosty — a slot game masterpiece developed by Betsoft with the most immersive graphics we’ve seen and a super-generous bonus round when you land three reindeer (we triggered it!).
Another great feature is that the minimum and maximum bet size is clearly displayed before you even load the game, allowing you to choose a preferred stake without jumping from one slot game to another until you find one that accepts 10c per spin.
On the downside, BetUS doesn’t organize their slot machine games too well (no filtering options are available), making it difficult to sift through their many titles.
Casino Games: 4.7/5
The table games are one of the top highlights at BetUS. Aside from all the standard offerings, they provide games rarely found at other online casinos, including War, Mississippi Stud Poker, and Red Dog (yeah, it’s a game, not our top pick for today).
Welcome Bonus: 4/5
New players can use the bonus code CAS150 for a 150% casino bonus up to $5,000. The
wagering requirements for this bonus are 30x, and there’s a time limit of 14 days for players to complete the playthrough.
Note that you’ll need to deposit at least $50 to activate this bonus.
Banking: 4.5/5
Players can choose from Visa, MasterCard, wire transfer, Bitcoin, Litecoin, and a couple of other crypto options for deposits.
For payouts, BetUS offers bank transfers and cryptocurrencies, but you can also get in touch with support members to find out more about additional payout options.
Withdrawal requests are cleared within 48 hours at most, which is slower compared to other casino sites on our list.
Misc: 5/5
If you like sports betting as much as you do playing online slots, then BetUS may be for you.
They offer all the major sports and an incredible number of alternative leagues — including over 40 soccer leagues and 16 different basketball leagues. The coverage extends to entertainment, esports, and horse racing betting options for a total of over 100 betting markets with top odds.
Furthermore, they have a dedicated section for BetUS TV, where they cover all the major sports, providing news, odds, and predictions.
5. BitStarz (Master of Starz) – Best Site for Bitcoin Slots
Pros:
- More than 1,000 online slot games
- Over 40 table games, including rare titles
- A dedicated crypto casino, specializing in Bitcoin games
- 20 free spins upon email verification
Cons:
- Geo-restricted live games for some players
Bitcoin and crypto casinos have been growing in popularity lately, so we wanted to include one of the best Bitcoin casinos as an option for you.
If you enjoy playing online slots — you’ll definitely find something that tickles your fancy among Bitstarz’s selection of 1,000+ slot machine games.
Slot Games: 4.5/5
This Bitcoin slot machine platform has to score big here because of the sheer number of real money slots games alone. However, many of the games are geo-restrive, which means that not all of them will be available if you reside within the US.
We especially liked how Bitstarz marks the games “Hot” and “Cold,” depending on how much they’ve paid out in the last 24 hours. If you’re the superstitious type — this is the perfect feature for you.
Bitstarz is also the only casino on this list where you can enjoy exclusive titles. That said, our top game here was Master of Starz, which is also the biggest progressive jackpot you can enjoy here.
Casino Games: 4.5/5
The number of table games at Bitstarz is also good, with unique titles like Sic-Bo, Pontoon, and 3D versions of popular titles like roulette and Texas Hold’em.
They do offer a few video poker games and other unique table games, but this side of the online casino is a bit unorganized, so players will have to poke around a bit to find them.
Welcome Bonus: 4.8/5
Upon signing up and verifying your email, Bitstarz will give you 20 free spins as a welcome aboard gift. The wagering requirements are 40x, but there’s no harm in claiming them since you’re not required to deposit.
Once you are ready to lay down some cash, you can get 100% up to 1 BTC plus 180 free spins on your first deposit. If you continue playing beyond that, you can amp up your casino bankroll with 4 BTC extra across your next three deposits, totaling an impressive 5 BTC welcome package.
If you haven’t got any favorite slot games you like to play, check Bitstarz’s Slot Wars and see which games are eligible. By playing them, you’ll have the chance to win a slice of a $5,000 and 5,000 free spins prize pool.
Banking: 4.5/5
The banking options at BitStarz are limited to cryptocurrencies, with a few more traditional methods for players residing outside the US. However, they do provide the option of using a credit card to purchase Bitcoin directly on their site.
The best thing here is that Bitstarz is actually the quickest online slots casino when it comes to payouts. You’ll get your crypto withdrawal in an average of 7 minutes each time you request a withdrawal — which is the fastest time frame among all the best Bitcoin casino sites.
Misc: 3/5
For those that have access to Bitstarz’s live dealers, you will be treated to an amazing selection of games that most casino sites do not offer. These include unique live wheel games, sports-themed titles, and even game shows like Deal or No Deal and Monopoly.
However, it’s a bit unfortunate that so much of Bitstarz’s game repertoire is geo-restrictive and that you won’t get to enjoy the entire experience just because you reside in a certain country.
>> Create an account at Bitstarz and enjoy playing slots online with the 20 free spins no deposit bonus.

All About the Best Online Slots Sites & Online Slot Machines
Are Real Money Online Slots Rigged?
Real money slot games at legit online casinos have an RNG (Random Number Generator) algorithm that prevents rigging the outcome in anyone’s favor. Online slots do have a house edge that plays out over time in favor of the casino, but no one — not even the casino itself can shift any particular outcome to their advantage.
That being said, it’s always best to stick with online casinos that are licensed with all of their games tested by reputable organizations. Since your safety is our top priority, we only recommend legit online casinos that take measures to create a safe gambling environment.
Are There Real Money Slots Apps?
Some online casinos do offer dedicated mobile apps. However, most slots site brands or online casinos now just optimize their web-based platform to work as a dedicated app, so that you do not have to download any additional applications.
Can I Play Free Slots at Online Casinos?
Many online casinos, like our top-ranked Red Dog, let you play demo versions of their games. Some players like this option because it allows them to play games that they are unfamiliar with before betting real money.
How Do I Know Which of the Best Online Casinos is Best for Me?
Choosing which are the best gambling sites to play real money slots at depends on what other features you are looking for, like a generous welcome deposit bonus or the number of progressive jackpot slots available.
Ultimately, it boils down to your personal taste in online slots, but one thing to always have in mind is to never deposit with an unlicensed casino.
