Slots Ninja may be a new online casino, but it’s hardly wet around the ears. True to its name, the site has quietly climbed the tower to become one of the best online casinos in the business. Of course, that isn’t a surprise, as the venue is part of the Entertainment Software Group (ESG) family, one of the leading online gambling brands in the world.

Given Slots Ninja’s pedigree, we like the casino and give it high marks across the board. Like other ESG casinos, we’d like to see a larger menu of games, as its 160-game selection makes it one of the smaller sites out there.

On the other hand, every game is made by Realtime Gaming, so there’s never any doubt about the quality of the titles you choose. Basically, if real-money online slots are more your speed than table games, you can hone a pretty sharp edge at Slots Ninja Casino.

Honest Slots Ninja Review For 2022

Slots Ninja is one of the newest online casinos, having just launched in 2021. However, despite such a short time under its (black) belt, the site achieves high marks across the board. It’s already one of the most legitimate online US casinos on the market.

But we’re not just here to signal the all-clear and then disappear across the rooftops into the night. Instead, we’ve put together the most comprehensive, detailed Slots Ninja casino review on the Internet to show you exactly why the site can be trusted.

You might be a solitary warrior, but you don’t have to go it alone. We’re here to help you make the most of your legal online gambling experience, and if we can help you score a few “kills” in the process, all the better!

So to learn more about Slot Ninja Casino – and to see how you can score a Slots Ninja Casino no-deposit bonus code to try before you buy – read on, grasshopper!

Is Slots Ninja Casino Legit? – What We Look For In A Legitimate Online Casino

There are lots of things to consider when reviewing any online casino. Some matter more than others, and some matter a lot more than others. While we’re interested in gauging an online casino across all its aspects, we really base our overall review score on how a given site does meeting the mission critical criteria that no legit online casino can afford to skimp on.

Now, we could just tell you to quit worrying and to sign up at a given site if it gets our go-ahead, but we think it’s more important to tell you why a site receives our approval in the first place. To that end, these are the things we look for in any legitimate gambling site offering legal USA-friendly real-money betting online:

  • Licensed in, authorized, and/or regulated by a legitimate offshore gambling jurisdiction
  • Legal ability to accept USA players at 18+ or 21+
  • State-of-the-art cybersecurity standards and practices, including SSL/TLS encryption for all connections
  • Commitment to customer privacy – Never shares or sells personal or financial member information
  • 100s of legal online slots, table games + live-dealer casino games
  • Live-dealer casino with live casino tables available 24/7/365
  • All electronic online casino software developed by reputable brands (RTG, Betsoft, Nucleus, Rival, Dragon, etc.)
  • All online casino games regularly audited to ensure fair iGaming compliance + real-world win rates
  • Zero tolerance policy for cheating, bonus abuse, etc.
  • Attentive customer service available around the clock via live chat, telephone, email
  • Supports standard bet funding methods such as credit/debit, bank wire, cashier’s check, money order
  • Supports modern crypto bet funding methods such as Bitcoin, Bitcoin Cash, Litecoin, Ethereum, etc.
  • All payouts guaranteed on time and in full
  • Cryptocurrency withdrawals rated for same-day payouts
  • Legit online casino bonuses with fair, attainable rollover/playthrough wagering requirements
  • Excellent brand/parent company reputation with longevity in the online casino gambling industry

The art of ninjutsu is far from safe, but online gambling isn’t about being brave and facing down bad actors. There’s no glory in playing with shady venues, shadow warrior though you might be. Instead, you should only spend your money and time playing legit online casino games at legit online casinos that are safe and secure for all members.

To that end, every site we recommend has numerous performance guarantees and adheres to the strictest standards of fair iGaming operations. As a member of the ESG family of online betting sites, Slots Ninja is a cut above, and all US players can gamble there without hesitation or fear. Just like real ninja!

Yes! There are actually no federal US gambling laws barring access to offshore online casinos, and only one state – Washington – has specific mandates that disallow all forms of online real-money betting. As long as you live anywhere but WA, you’re good to go.

Note: SlotsNinja accepts players from Washington, but even though the state doesn’t seem to enforce its own gambling ban, we must recommend that you abide by all local laws. We know that’s not a super ninja thing to do, but we’re obliged to insist.

As of 2022, players from the following Slots Ninja excluded countries are ineligible to join Slots Ninja Casino:

  • Australia
  • Austria
  • Belgium
  • Bulgaria

Warning: Legit online casinos blacklist IP addresses from restricted countries. It is not recommended that you use Slots Ninja with a VPN to “trick” the casino into letting you sign up and play. Slots Ninja uses cutting-edge KYC (Know Your Customer) standards, so you must prove your identity and have a whitelisted residential address to collect your winnings.

Does Slots Ninja Casino Accept Players From Other Countries?

Yes! However, there are various limitations to this. No legit online casino accepts players from all countries, as each nation has its own gambling laws. Many countries, such as the United States, have no laws that bar individuals from accessing offshore sites and gambling for real money. Many other countries, however, do.

To see if you’re eligible to sign up at Slots Ninja, you can check the list of Slots Ninja restricted countries above, or you can simply try to sign up using a non-masked IP address. If you live in a restricted region, Slots Ninja will not allow you to complete the enrollment process.

How To Sign Up At Slots Ninja Casino

If you’ve joined a legit online gambling site before, you don’t need an in-depth Slots Ninja review to tell you how signing up works. The process is pretty much the same at every trusted vendor that serves the US market.

However, if you’re at least 21 years old and are thinking about joining a legit casino site for the first time, you might feel intimidated about the process. Fortunately, there’s nothing to it.

Here’s how to easily create a Slots Ninja login and user account, and it only takes a minute:

  1. Follow any link on this page to SlotsNinja Casino and click or tap the “Sign Up” button.
  2. Enter in all requested personal information. Slots Ninja doesn’t ask for as much info as other sites, so you’ll only have to put in your name, email address, phone number, and residential address. However, since the site uses Know Your Customer (KYC) standards to protect your account, please be sure to use only real, verifiable information and never sign up from a restricted region behind a VPN service.
  3. Select any supported Slots Ninja deposit option. We recommend cryptocurrency, as crypto transfers have 100% deposit success rates, earn the best casino bonuses, and allow you to claim same-day payouts when you win.
  4. Complete your free SlotsNinja signup and then enter your Slots Ninja login to access the members-only portion of the site.
  5. Browse, bet, and win!

Online Slots Ninja Casino Games

Finding the best online casino games is never easy. Now, hopefully, you didn’t just join the first site to pop up in a web search and call it good. Because trust us, it probably won’t be. Do that, and you’ll have to rely on quite a bit of luck just to ensure that the games themselves are on the up and up.

But you can abandon that wishful thinking if you go with SlotsNinja. Remember, ninjas don’t wish upon a star, they throw them!

When it comes to game selection, Slots Ninja shares many similarities – in both content and reputation – with brand sister sites such as CasinoMax, Cherry Jackpot, Roaring 21, and SlotsRoom. Of course, these sites aren’t just clones of one another. They each have unique features, online casino bonuses, and emphasize different games and styles of play.

That said, because Slots Ninja shares a “pool” with so many other legit online casino sites, their progressive slots jackpots tend to be higher than most competing non-ESG brands. (This is one of the biggest benefits of gambling with a site that’s part of a larger network instead of a standalone venue like Bovada Casino.)

Fun Fact: In America, slot machines are called slot machines. However, in the rest of the English-speaking world, slot machines are called fruit machines. Thus, you might be tempted to call Slots Ninja “Fruit Ninja.” But be wary of the trademark man. Fruit Ninja-branded casino games actually exist at some brick-and-mortar USA casinos, but trust us, they’re not nearly as fun as these Slots Ninja casino games. 

If you couldn’t tell by the name, legit real-money online slot machines are the order of the day at Slots Ninja. Over 130 of the site’s 160 games are online slots, and the selections run the gamut.

From 3-reel slots and 5-reel slots to 6-reel slots, bonus round slots, and progressive jackpot slots with payouts ranging from four figures to seven figures, you’ll always have something to play.

Just remember to keep your head on a swivel, ninja. How you do you think the one-armed bandit lost his arm? He remembers…

  • Aztec’s Millions - $1M+ Jackpot
  • Megasaur - $1M+ Jackpot
  • Eagle Shadow Fist
  • Bubble Bubble 3
  • Ninja Star


After slots, online blackjack is the most popular Internet casino game going. And Slots Ninja blackjack is even more apropos than usual. See, in addition to their normal arsenal, ninja were known to commonly carry blackjacks themselves. If they wanted to get a silent KO, they’d use these to do it.

Of course, if you play legit online blackjack and put the house on the mat with four winners on a pair of split 8s, we wouldn’t hold it against you if you made a little bit of noise.

Popular Slots Ninja Blackjack Games

  • Classic Blackjack
  • Blackjack + Perfect Pairs
  • Suit ‘Em Up Blackjack

If you want to play legit online roulette games, you can do that at Slots Ninja. However, if RNG electronic roulette is your primary game of choice, we’ve got to recommend that you try out a different site.

Oddly, this operator only features one single roulette game in its entire menu: European roulette. And they keep it in the “Specialty” games category! Seriously, the site doesn’t even have American roulette with its longer odds and better payouts. This is a genuinely befuddling oversight.

Popular Slots Ninja Roulette Games

  • European Roulette

Video poker is the second biggest gambling category at SlotsNinja, with nearly 15 different online poker sims to choose from. If you’re an online video poker regular, you’ll recognize all the titles and their standard wild card variations on a theme.

From “Loose Deuces” and “Jacks or Better” to “Joker Poker,” “Deuces Wild,” “Aces and Eights,” and more, you won’t run out of electronic poker hands to play any time soon.

Popular Slots Ninja Video Poker Games

  • Aces and Eights
  • Deuces Wild
  • Jacks or Better
  • Joker Poker
  • Double Double Bonus Poker

Along with roulette, any titles not included in the categories above are considered online casino specialty games at Slots Ninja. However, you actually won’t find some of the main casino game types you probably expect in this section.

There are no online craps games at the site, nor are there any electronic online baccarat games or mini-baccarat games. If you like those classics, you’ll have to play elsewhere.

That’s certainly not ideal because it’s such low-hanging fruit for an online casino to offer baccarat and craps sims, but maybe most players these days just don’t like those old games as much as we do. But at least they’ve still got legit online keno.

Popular Slots Ninja Specialty Games

  • Banana Jones
  • Fish Catch
  • European Roulette
  • Keno

In a battle of ninja vs. samurai, slot machine games are all well and good. But if it’s just you against the computer, how legendary can you really be? Well, pretty legendary if you hit a big jackpot. But in keeping with the theme, the point is that if you really want to test your gambling skills, you’ll want to play live online casino games.

Because of recent advancements in Internet speeds and coverage, more people than ever are doing more things than ever online. And playing live casino games rather than just RNG casino games has been one of the big trends over the last few years.

Fortunately, the leader in live casino games – Visionary iGaming (ViG) – is the exclusive service provider at Slots Ninja. ViG offers the following games in its gambling suite, and you can find a dozen or so tables open around the clock at Slots Ninja:

  • Live-Dealer Blackjack
  • Live-Dealer Roulette (American)
  • Live-Dealer Roulette (European)
  • Live-Dealer Baccarat
  • Live-Dealer Super 6 (Mini-Bac)

Each live casino game offers multiple table limits, making the Slots Ninja live casino a welcoming place to play for all. And, in case you want to “try before you buy,” you can actually spectate the games without anteing up.

Once you’re ready, just click or tap on an empty seat, make your wager, and watch your dealer pass out the cards or spin the online roulette wheel in real time. You can also chat with your dealer and other players at your table, and ViG’s live casino software even allows you to play real-money casino mini-games while you play live games.

(We obviously don’t recommend this for beginners since it’s quite the distraction if you aren’t already a grandmaster of the craft, but it’s pretty neat that it's actually an option. It definitely brings an element of non-stop speed to the live game, which is generally slower than RNG gambling since each player has 45-60 seconds to place their wagers and make their choices as the action goes around the table.

Our Slots Ninja review is pretty favorable, but it’s not all good. In fact, when it comes to free online casino games, SlotsNinja – and its many sister sites – all have the same huge flaw: You can’t test the waters!

These days, it’s commonplace to gamble with an online casino that lets you try out the games before you risk real money. Most sites brand this as “practice mode” or “demo mode,” and it allows players to learn the ins and outs of every new title before risking actual cash. (Even for seasoned gambling pros like us, this is a really desirable feature when you’ve got more than 150 games to learn.)

Again, this isn’t a dealbreaker, but it’s definitely a bit of a bummer. Even if you aren’t a beginner, sometimes you just want to play a free online casino game without being nickeled and dimed by those “free” iPhone casino apps and Android casino apps that charge microtransactions every five minutes.

At any rate, understand this going in: There are no free online slots, free online blackjack games, free video poker games, free roulette games, or any other gratis gambling fare at the ol’ Slot Ninja. There are plenty of Slots Ninja free spins, but there are no Slots Ninja free slots.

Slots Ninja Online Casino Software

The reason it’s so easy to recommend a new online casino like Slots Ninja after such a short time on the market isn’t only because the venue is an ESG brand. Perhaps even more important than that is the fact that Slots Ninja exclusively offers Realtime Gaming online casino games.

Realtime Gaming (RTG) is the leading casino software developer in the world, and they’ve been in business since 1998. In fact, RTG was founded in the United States, moving their operations from Atlanta, Georgia, to Costa Rica in 2007 before being sold to Hastings International.

Roughly 80% of the best online casinos we recommend partner with RTG, though many of these sites pad their portfolios with games from other developers, as well. In the case of Slots Ninja, their exclusive reliance on RTG games is why the site’s 160-game menu is a bit lighter than the selections at other top outlets.

Another important point is that all Slots Ninja RTG casino games are audited once per month by Technical Systems Testing (TST). TST is a subsidiary of Gaming Laboratories International (GLI), a recognized industry watchdog that puts online casino titles through their paces to ensure players get fair win rates, paylines, and payouts.

Slots Ninja Banking Options – Deposits And Withdrawals

After the games themselves, the soul of any online gambling site is its online bet funding menu. It’s like the katana to the ninja. Or whatever that smaller backup sword is that ninja use. The wakizashi. That. The banking menu is like the wakizashi.

To bet online, you need to be able to move money into and out of your account. You’ve got to get up close and personal with those gambling finances. Well, Slots Ninja supports all the most common ways to do that, including Visa, Mastercard, American Express, Discover, JCB, and the most common bet funding option of them all, Diners Club!

Of course, card deposits come with added fees and can sometimes be interrupted by the UIGEA law (if you live in the US, at least). As such, SlotsNinja also supports Bitcoin and four other crypto coins, including Bitcoin Cash, Litecoin, Ethereum, and Dogecoin.

For payouts, you also get access to the most common online gambling withdrawal options, such as bank wires, courier checks, and crypto.

*Ethereum is not always going to be available as a SlotsNinja Casino deposit option. This is due to the comparatively high ETH network fees (aka ETH “gas fees”) that occasionally plague the network. Generally, we recommend depositing and withdrawing in Bitcoin or a less expensive altcoin.

  • Bitcoin (BTC) – $30 min, $4000 max
  • Courier Check - $250 min, $3000 max
  • Bank Wire - $200 min, $4000 max

Interestingly, while you can deposit in five different crypto coins at SlotsNinja, you can only withdraw in Bitcoin. This is less than ideal, and we’d like to see the site support a larger variety of altcoins, including third-gen Proof-of-Stake cryptos like Cardano, Avalanche, and Solana. Once that happens, Slots Ninja will be right up there with the fastest payout online casinos.

Slots Ninja Promotions – Slots Ninja Bonus Codes 2022

The main way online casinos of merit compete against one another is typically not in the quality of their games or the other betting markets they offer (although we do wish SlotsNinja had sports betting and poker so it could serve as a one-stop shop for all things online betting).

The main way they duke it out is with their selection of online casino bonuses. In this regard, we’re actually quite pleasantly surprised. Slots Ninja has better bonuses than most other top-tier sites, and they’ve even got better bonuses than their ESG sister sites!

Aside from the SlotsNinja welcome bonus which has a 50X rollover, all other Slot Ninja bonuses come with 40X wagering requirements. For online casino bonuses, this is very low.

But aside from that – and from the quantity of bonuses on offer – the thing that surprised us most of all was the fact that not only does Slots Ninja actually have a legit no-deposit bonus, but the Slot Ninja no-deposit bonus – which is a $40 free chip – has the same 40X rollover as everything else.

You can’t find no-deposit bonuses all that often at any legit casino these days, but to actually come across one with a reasonable rollover rate – and not a scummy 100X playthrough “account killer” – is something we just didn’t expect.

Slots Ninja Casino App – Legit Slots Ninja Mobile Casino

Without an online gambling suite that’s 100% mobile-accessible from anywhere, no betting site would ever be able to stay afloat. These days, 75% of all online gambling is done via mobile, and that number’s only getting bigger.

That’s why SlotsNinja – and every other venue that passes muster among our legit online casino reviews – has gone the extra mile to ensure that their all their games are available natively via mobile.

There’s nothing to download or update, which means that there’s no Slots Ninja iPhone app or Slots Ninja Android app. Instead, everything is 100% web-based and available right through any up-to-date mobile web browser, so you get all the following:

  • Full compatibility with all smartphones/tablets
  • No mobile Slots Ninja app downloads
  • No mobile Slots Ninja app updates
  • All desktop games/markets available via mobile
  • No GPS restrictions/geofencing - Play from anywhere in the US!

We tested Slots Ninja on iOS and Android (iPhone 7 Plus, iPhone 11, iPhone 12 Pro Max, iPad Pro Gen. 1, Google Pixel 4a, and Samsung Galaxy S20 Ultra), and the experience was uniform across all these devices. Because Slots Ninja Casino uses responsive web design, you’ll get the same visuals and animations regardless of mobile make, model, or screen size.

Best of all, there’s no geo-fencing, so you can play anywhere in the US and abroad. After all, a ninja has to be able to travel halfway across the country at the drop of a sentry.

Slots Ninja Customer Service

Ninjas solve problems. That’s what they do. And SlotsNinja does, too.

  • Slots Ninja Email Address:
  • Slots Ninja Chat: On-Site, 24/7

2022 Slots Ninja Review Summary – Should You Join Slots Ninja Casino?

We’re pretty big fans with Entertainment Software Group websites in general, and Slots Ninja is no exception. If you’re already a fan of ESG sites like CasinoMax, SlotsRoom, Roaring 21, and Cherry Jackpot – and if you already have a membership at those sites – you may not find enough variation at SlotsNinja Casino to warrant the switch.

However, if you’re not a member at any ESG casino, we think the SlotsNinja bonuses put this site over the top compared to its siblings.

We’d like to see a more refined overall site design (and maybe a less cartoony presentation that played up the “ninja” theme with a bit more edge), but the overall vibe is neither better nor worse than other ESG sites.

The SlotsNinja game selection – topping out at about 75-100 fewer RNG casino games than its main competitors – might seem like a weakness at first, but it truthfully isn’t. Chances are, you’ll never even play – or even try to play – all 160 of the titles on offer.

If you’re anything like us, you’ll test out about 30-40 games before settling on a dozen or so favorites (which you can keep in their own special tab for convenient access, by the way) and call it good.

So, is Slots Ninja the absolute best real-money online casino out there? Probably not. No casino can objectively lay claim to that. But is Slots Ninja a legit online casino that’s worth your patronage? We think so.
