First Impression

Slots Ninja Casino was launched in 2021. Generally, we’re a bit more skeptical of new brands. However, Slots Ninja Casino is part of the Entertainment Software Group NV, a highly-respected online gambling operator here at Casinomeister.

Slots Ninja Casino is powered exclusively by Realtime Gaming software. This means you won’t find games from other game developers; if you’re looking to play casino games from other software providers, you may want to consider choosing a different casino.

Slots Ninja Casino offers a pretty generous welcome bonus (details of which we’ll cover in the following subsection of this review), and they also run a VIP scheme which we will cover.

When it comes to deposits and withdrawals, Slots Ninja Casino accepts all major debit and credit cards, and they’ve recently added support for various cryptocurrencies, including Bitcoin. We expect to see more payment methods added in the future.


  • Slots Ninja Casino is ran by a trusted RTG operator

  • Management team is very experienced

  • Large progressive jackpot amounts

  • Now accepts cryptocurrencies

  • Instant withdrawals via Blue Rewards Card, no fees


  • No UK players allowed

  • Maximum weekly withdrawal limit of $4,000

  • Somewhat weak Curaçao license


Like all RTG casinos, Slots Ninja Casino tends to offer a much more generous welcome bonus when compared to conventional casino welcome bonuses. Below, we’re going to take a look at the details of this welcome bonus promotion.

Welcome Offer

The main welcome bonus at Slots Ninja Casino is generous, and it allows you to claim up to $10,000 in bonus money. Yes, you read that correctly; $10,000. Slots Ninja Casino offers all new players a 100% matched deposit bonus, plus 200 free spins. The wagering requirements for the welcome bonus are just 40X, so you stand a pretty good chance of actually managing to get a cashout.

What’s more, when you claim the deposit bonus, the bonus money is immediately available on your account. You can use those funds to play pretty much all casino games and video slots with relatively few game exclusions.

No-Deposit & Free Spins Offers

Some casinos offer a no-deposit bonus. Slots Ninja Casino does not. However, they do have a free spins promotion. This promotion allows you to claim 200 free spins when you make your first deposit, and these free spins are distributed at a rate of 20 per day for the first 10 days after you create your account.

The minimum deposit required to claim these free spins is just $20, affordable to all players. The first batch  of 20 free spins will be automatically credited to your account as soon as you sign up and make your first deposit — so you’re able to begin playing right away.

Please note: the free spins come with some Terms and Conditions — just as the primary deposit bonus does — and you’ll need to complete wagering requirements of 40X before you’re able to convert the bonus funds from the free spins into real, withdrawable cash.

If Slots Ninja Casino chooses to start offering a no-deposit bonus in the future, we’ll update this casino review accordingly. If you do want to claim no-deposit bonuses, you should consider checking out some of the other casino reviews here at Casinomeister, as many of our top-rated Accredited casinos offer no-deposit bonuses as well as no-deposit free spins.

VIP and Loyalty Programs

The loyalty program at Slots Ninja Casino is a fairly standard comp points-type scheme. This means you’ll earn points for doing things like depositing and wagering real money. Every 100 comp points are worth $1.

Slots Ninja Casino allows you to make deposits in quite a few ways – although the number of withdrawal methods available at this casino is much more limited. Slots Ninja offers the following deposit methods: debit and credit cards, Interac, bank transfer, cheque, Bitcoin, Litecoin, Ethereum and Bitcoin Cash.

Deposits are credited to your account instantly and there’s no fees applicable.

Withdrawal Speed

Slots Ninja aims to process all withdrawals within 48 hours. They have a weekly withdrawal limit of $4,000 —  which you should be aware of, especially if you plan to play at higher stakes.

Recently added is Blue Rewards Card, providing instant withdrawals with no fees!

Responsible gaming

Slots Ninja Casino takes Responsible Gambling seriously, which is quite unusual for a Curaçao-licensed casino. There’s a wide variety of responsible gambling tools that players at Slots Ninja Casino can take advantage of. While these aren’t, unfortunately, self-managed (you need to contact the casino’s customer support team to set them up), it’s a good sign that the online casino is committed to safeguarding those who play at the site.

Players are able to set up what’s known as a “deposit limit”. This allows you to control and limit the amount of money you deposit into your account daily, weekly or monthly basis. Once you’ve reached this limit, you will not be able to deposit any additional money until the time frame you set has passed.

Slots Ninja Casino also offers time-out and self-exclusion facilities, allowing you to take either a short- or long-term break from playing. If you choose to enter into a time-out agreement,  you’ll be able to block access to your online casino account for up to 6 weeks. The self-exclusion function lets you permanently block access to your account — and this is irreversible.

Customer support

Like their sister casinos, Slots Ninja Casino offers customer support 24 hours a day, seven days a week. This means you’re able to get the help and support that you need no matter what time of day or night you’re looking to play. The easiest way to contact the customer support team at Slots Ninja Casino is to use the live chat facility.

Live chat is a real-time chat portal that connects you directly to a trained member of the customer support team. The Live chat operates 24 hours a day, 7 days a week. It doesn’t matter whether you’re playing in the early hours of the morning or late at night — someone will always be available through the live chat portal to speak with.

To start a live chat conversation, you simply click on the green chat icon, which is found in the bottom right-hand corner of the screen. You’ll then be asked to enter your question or problem, and connected with an operator almost immediately.

If you’re on a mobile device, then using the live chat function – while possible – may be difficult, especially if your internet connection isn’t particularly stable or if the size of your mobile device’s screen is quite small. Another way to contact the customer support team at Slots Ninja Casino is by emailing them. However, you should be aware that email response times are quite a bit longer, and you may find yourself waiting up to 48 hours to receive a response from the customer support team.


Slots Ninja Casino requires that all players verify their identity before making a withdrawal. This is called a Know Your Customer (KYC) check, and it allows Slots Ninja Casino to verify your age, address and date of birth.

When you request your first withdrawal, Slots Ninja Casino will ask you to upload certain identity documents — this usually includes a copy of your ID and a copy of a recent bank statement or utility company bill or letter.

Website Experience and Features

Desktop and Mobile Gaming

Slots Ninja Casino is fully mobile-optimized. This allows you to enjoy the casino games and video slots from your mobile devices, without the need to download or install a mobile application. To access the mobile-optimized version of the casino, you simply navigate to Slots Ninja Casino with any mobile browser. You will then be redirected to the special mobile-optimized version of the online casino, where you can log in or create your account.

At the time of writing this Slots Ninja Casino review, we tested the mobile casino on various devices, including phones and tablets. While the mobile casino isn’t as modern or up-to-date as some European online casinos, Slots Ninja Casino ensures that players can play all of their favourite games without having to worry about downloading or installing any special software.

Brand games


As we’ve mentioned a few times throughout this review, Slots Ninja Casino is an online casino that’s powered entirely by RTG – Realtime Gaming. This means that all of the casino games available to play are from RTG — you won’t find games from other software providers.

Below, we’re going to be taking a look at some of the most popular game categories – and games – that you’ll find on offer at Slots Ninja Casino.


Slots Ninja Casino provides players with the chance to enjoy a wide variety of video slots – and it is, by far, the largest part of the online casino’s game library with more than 250 different titles available to play.

At the time of writing, one of the most popular video slots you’ll find offered at Slots Ninja Casino is Spirit of the Inca – a thrilling game that is action-packed, fast-paced and offers up some great win-potential.

Unlike some of the game developer’s older video slots, Spirit of the Inca offers modern, state-of-the-art graphics and animations. There’s a lot of action with wilds, scatters, and an exclusive feature making up the game’s bonuses and features.

Live Casino

One of the biggest grievances we have with RTG casinos is that they don’t (yet) offer any live dealer games.

However, given that live dealer games are now more popular than ever, we strongly suspect that RTG is looking at solutions to this. We wouldn’t be surprised to see them introduced in the future.

Table Games and Video Poker

Like many of its sister casinos, Slots Ninja Casino doesn’t offer players the largest selection of casino table games to play. This comes as somewhat of a surprise to us as we’d expect to see the casino platform offering as many games as possible to players.

Still, you will find yourself able to play a few different games, including European Roulette and a few versions of video poker. Some poker-inspired casino table games are also available, such as: Caribbean Stud Poker and Casino Hold ’em.

Progressive Jackpots

Progressive Jackpot Caveat: Many if not all of the progressive jackpot games at this casino are supplied by Real Time Gaming – a decent software provider that has a relatively upstanding history at Casinomeister. If you are one of the few who win a progressive jackpot of substantial winnings, and you reside in a jurisdiction where payment processing might be challenging, you might not receive the winnings in one lump sum. These payments might be paid in monthly instalments. There is a thread in our forum which details one of these experiences here:
Just hit a huge progressive at Slotocash Casino…

Slots Ninja Casino has a small selection of progressive jackpot games for players to enjoy. Their offering is far smaller than what we typically see at online casinos. Still, this is likely down to the fact that Slots Ninja Casino only offers RTG games, so they’re not able to offer the vast selection of progressive jackpot games seen at many other online casinos.

You can find all of the progressive jackpot games at Slots Ninja Casino by clicking the ‘Progressives” tab on the main game navigation menu.

About the Team and History

Slots Ninja Casino was launched in 2021, making it one of the youngest brands in the group of online casinos owned and operated by Entertainment Software Group NV. The same online gambling operator operates other well-established and Casinomeister Accredited online casinos, including CasinoMAX and Cherry Jackpot Casino.

Slots Ninja Casino is licensed in Curaçao, and it runs on the RTG platform, which means that all of the casino games available at the casino are, indeed, from Realtime Gaming. The Slots Ninja Casino welcome bonus is more generous than most, and they offer a wide variety of ongoing bonuses and promotions to ensure that regular players are rewarded as well.

Complaints and Track Record

While Slots Ninja Casino doesn’t have much of a reputation yet here at Casinomeister, we can look at what players at some of their sister casinos have to say. For the most part, the player experiences are very positive, with few complaints. Plus, when complaints do arise, the team behind Slots Ninja Casino takes care of them quickly and promptly, ensuring that you’re never left waiting long to have your issues resolved.

Below, we’re going to take a look at what some of our players have to say about playing at Slots Ninja Casino’s sister brands like CasinoMAX and CherryJackpot Casino:

Milenmaster said: “I don’t want to be overly dramatic here, but my experience with the casino group that runs Cherry Jackpot and Casino Max is super alarming. In my two decades of gambling online, I have never seen anything as scary as what I’ve experienced yesterday and today.

Long story short, I sent my verification documents into their support alias and received an auto-reply. My documents consisted of a single PDF containing my driver’s license, utility bill, and front and back of the credit cards I used.

A few minutes later, I received a reply from their support indicating they would present my documents to the banking group, and included with that email was a direct URL <snipped URL>….. (sensitive url hidden) that linked directly to my PDF file.

THERE IS NO AUTHENTICATION IN FRONT OF IT. Anyone can use that link and view all of my personal data I sent over, and it’s just on the internet. I tried it on 2 different computers with 3 different browsers, including my mobile phone and my documents downloaded and appeared.

I contacted support and was told not to worry as there is only risk if someone finds out the URL goes to it. The odds of someone “figuring it out is unlikely”

This is unbelievably reckless not to put a password in front of it. My suggestion would be if you played at their casinos to check the confirmation emails you received when you sent your personal information and look for a link at the base of the email that begins with and click on it to see if your information comes up too.

It’s important to note that this comment wasn’t actually made at Slots Ninja Casino and was, instead, made it one of the online casino’s sister casinos. However, they were quickly resolved, and we have no reservations about recommending Slots Ninja Casino to our readers. The team behind the online casino is excellent, and they genuinely care about their players.
