MrO Casino Sister Sites

MrO casino currently has two sister sites that are quite similar to each other. Thanks to RTG software, they manage to attract quite a lot of players despite not having the best reviews. Another winning point for Eternal Slots and Goat Spins is that they offer no deposit bonuses, which is hard not to claim. All sisters have modern designs, and they heavily push crypto play. That is a fair point, as it is basically one of the very few options available for cashouts for Americans.

Overall, if you had a positive experience at MrO, then Eternal Slots and Goat Spins can deliver a nearly identical experience. You can get $77 no deposit at Eternal and 75 spins at Goat Spins.

Visit SiteGoat Spins Review

Goat Spins was launched in 2024 by an unknown company that popped up in 2023. The company has launched two other casinos, Mr O and Eternal Slots. Goat Spins and its sisters target players from the US by offering a full portfolio of RTG games. It would be great to see more information about the management as it is very hard to say if Goat Spins is a reliable brand or not.

We can only hope that GS is going to a safe place for Americans. So far, it has everything to do. High bonuses, RTG slots, and crypto banking. Once you register at Goat Spins, you get an exclusive offer of 75 no deposit spins (75SLOTS) and a 175% welcome bonus on the first deposit (SLOTS175).

The bottom line is that Goat Spins looks like a modern US friendly casino. Don’t let high bonuses fool you, and be sure to check all terms.

Visit SiteEternal Slots Review

Eternal Slots left us with mixed feelings. On the one hand, it is still a very new casino from an unknown company with no licensing information. Immediately, it is a red flag for us. But then again, many US-focused casinos operate just fine without a license. Still, being transparent about this kind of info is something that makes you feel safer.

On the other hand, Eternal Slots has everything to cater to Americans: RTG software, crypto payments, generous no-deposit bonuses ($77 free chip), and exciting welcome offers. They did everything by the book. Plus, most of the reviews are fairly positive.

Overall, Eternal Slots is nothing more than an average US casino with a good amount of games and lucrative promotions.

Alternative Casinos to Mr O

Since all Mr O sister sites are not proven with time yet, we would recommend checking out well established casinos from trusted companies available in the US.

Bonus Blitz is one of the most popular casinos, and it has mostly good reviews from customers who love fast payments, generous bonuses, and RTG games. Overall, RTG is essential if you want to target the US market, so all casinos we added feature these high-quality slots. Bonus Blitz is part of Casino Extreme family, which has been online for more than 20 years. This is one of the reasons why we recommend sites from this company. They might not have any crazy deposit bonuses, but they do value their customers.

Another casino we can suggest is Ignition, which might be the most famous casino in this market. It is packed with games from RTG, Betsoft, Rival and more. Moreover, you can find exclusive poker games and live dealers. It is definitely a go to casino for many customers! Plus, Ignition is known for smooth payments and support.

Visit SiteBonus Blitz Review

The fact that Bonus Blitz is coming from such a reputable family makes us excited. There are not so many reliable USA casinos out there so it is great to see that Casino Extreme extends its family and delivers such a nice product again.

Bonus Blitz has lots of green flags: superb RTG collection, fast payments with crypto, excellent promotions, modern design, VIP Lounge and so on. The list can go on but we think that Bonus Blitz has made its case.

The bottom line is that this casino is a great option for any American player who likes to play RTG slots and deposit with crypto.

Visit SiteSlots Room Casino Review

We were so happy that the Casino Max family launched another U.S. site. Like its sister sites, Slots Room is powered by RTG. This means there is a good selection of slots and table games from this popular software provider. The company is well known and reliable, so we knew from the start that Slots Room would be a hit.

Start off with a huge welcome bonus that gets as high as $10,000 with an additional 200 free spins! Your first deposit will be matched with 200% up to $2,000. Do not forget to use the code: WELCOME200.

Slots Room has a lot of potential to continue growing in this market. It is only a matter of time before it becomes your next favorite casino!

Visit SiteSlots Ninja Review

Given the huge success of Casino Max and Spinifinity, it is no surprise that the company keeps treating players by releasing new brands. The main focus of the Slots Ninja is quality slots by RTG, an essential software developer for the US market. Nevertheless, customers will also be able to enjoy live dealers with Visionary. 

Slots Ninja’s biggest attraction is its welcome promotions. We definitely recommend trying the site with crypto as you will get a boosted offer: a 500% match on your first deposit. If you decide to stick to Fiat, you will still get a very lucrative promo: 350% on slots that you can use 4 times!

In no time, Slots Ninja will become one of the go-to places for American players who enjoy quality games and fast withdrawal times.

Visit SiteIgnition Casino Review

In a few words: if Bovada is the most popular gambling site in the US, Ignition is the most popular casino site. Ignition was launched solely as a casino but it became also a Poker Room, however unlike in Bovada, in Ignition the casino is the main thing. 

Ignition is perfect for more seasoned / advantage casino players. It’s more classic in its design and layout, the bonuses are not crazy but offer great value for money. Plus you can enjoy a wide array of Live Dealer games and of course Poker tables if you like to mix things up. 

Highly reputable and trustworthy.

Visit SiteLimitless Casino Review

If you’re looking for an excellent new online casino, be sure to check out the latest addition to the Casino Extreme family: Limitless Casino. It offers an impressive selection of games from RTG, the most popular software among players in the U.S.

One of Limitless Casino’s standout features is its unlimited cashouts, which are advertised as being processed within minutes. While it may take longer due to verification and other factors, the cashout times are still faster than those of most other sites.

Limitless Casino also boasts amazing bonuses and promotions to keep players coming back. For instance, you can grab 100 spins when you sign up using the code LIMITLESS100.

Review & Promotions

Mr.O Casino provides a 400% welcome pack up to $10,000 and 200 free spins. The minimum deposit amount is $10, and you must use the promo code KICKOFF to unlock the offer. Free spins are credited in 5 sets of 80 spins after the deposit bonus has been used. The welcome package is subject to 40x wagering requirements (deposit + bonus funds), the maximum bet per hand is $10, but the offer has no maximum withdrawal limits.

If you redeem the coupon SLOTS111, you can claim a 111% match on the first deposit up to $200. The minimum eligible deposit is $20, the maximum bet per hand is $10, and the wagering requirements are just 1x (deposit + bonus). 

No Rules Bonus is another exciting promotion you’ll activate using the promo code FRENZY. The bonus value depends on your deposit.

Software & Games

Mr.O online casino offers titles from SpinLogic Gaming (RealTime Gaming). Consequently, the library is not as impressive as some others, but the quality of the gaming experience is not always in numbers. Mr.O Casino is a good example, providing slots, table games, crash games, video poker and specialty games. 

As you can see, the diversity is guaranteed. The most popular titles include Robin Hood’s Riches, Great Golden Lion, and Mighty Drums, while the latest releases are Bass Baggin, Glam Cash, and Punky HalloWin Mega Cascade. The great thing about Mr.O Casino we must highlight is the categorisation. Not only does the casino let you sort games by categories, but you can use additional filters, like 3 Reel, 5 Reel, Floating Symbols, or Pays Any. 

Popular table games are 32 Cards, Caribbean Stud Poker, Andar Bahar, Suit’em Up Blackjack, Baccarat and Teen Patti. You can also find a great selection of video poker titles, like Aces & Eights and Deuces Wild. However, if you like live dealer titles, you’ll have to search them somewhere else. 

Specialty games offer Keno and an engaging arcade game, Banana Jones. If you like crash games, check out one of the latest releases from SpinLogic, Galaxy Blast.  

Banking 

The Mr.O Casino is a crypto-friendly casino allowing you to deposit with Bitcoin, Litecoin, Bitcoin Cash, Ethereum, Tether, Binance, BTC Lightning, Solana, Dogecoin, and Tron. The minimum deposit amount is $10 or 0.0003 BTC. If you prefer fiat options, you can use PayPal to make deposits. 

Cashouts are available only with Bitcoin and Litecoin. The minimum withdrawal is $20 and the maximum payout is $4,000 a week. However, if you reach a higher VIP level, you can cash out more (for example, up to $12,000 if you’re on level 3). 

Summary

Mr O Casino is the first casino launched by this group, which decided to be anonymous. We believe that transparency is key to being a successful casino, especially if you are a new player on the market.

Besides that Mr O is a solid option with popular RTG games, crypto payments and lucrative bonuses.
