US-friendly MrO Casino is one of the online gambling destinations where players do feel at home. The place is named after a cheerful character who is a passionate gamer himself and hence knows exactly what punters need and want.

Indeed, the website’s library caters to almost all tastes and preferences, featuring a diverse assortment of Bitcoin slots, table games, and video poker. We say almost because MrO does not offer live dealer entertainment, so those looking to tap into the authentic brick-and-mortar atmosphere are clearly out of luck and should continue to search for their perfect live casino.

On the bright side, punters whose gameplay is mainly online slots, blackjack, or poker are gonna love what they will see once they land on the page with promotions. Seasoned pros would agree that not many places nowadays provide truly lucrative bonuses with no strings attached and the great news is this site lets players benefit from fantastic no-rules deals!

As always, you will find all the details about promotions in the dedicated section of this review but skipping ahead a bit, get ready for an extravaganza of daily bonuses. Plus, more exciting rewards, including cashback on all lost bonus-free deposits, are delivered by the website’s loyalty program, so keep reading to learn how to make the most of your favorite pastime.

Just a few strokes more to complete the overall picture. All customers can count on 24/7 support provided by the team of competent agents via Live Chat, therefore should you have any questions or concerns, do not hesitate to reach out for help. Naturally, you can write an email too, but then, probably you will have to wait for a reply for several hours – it is not for nothing that Live Chat is the most praised by patrons channel to contact customer service. Well, some people still give preference to an old good phone call, which is another fast and convenient way to get your problems solved, but MrO does not offer it.

The website also has a pretty informative FAQ section that offers answers to common questions about banking, bonuses, and, of course, a registration procedure. The latter, by the way, is very fast and uncomplicated – all you need to do to create an account is to provide your name, email address, and phone number, as well as set up a password.

Casino Software

MrO Casino is not one of those places that boast dozens of software providers, which actually makes perfect sense given that the majority of studios are not available for US players. Focusing on its target audience, the website relies on the state-of-the-art RTG platform worldwide renowned for its high-quality performances and diverse gaming catalog. 

In contrast to many RTG-powered sites, this one does not provide an option to download software, therefore users can choose between desktop and mobile play. It goes without saying, the version for portable devices is sleek and responsive, leaving no room for flaws and unpleasant surprises on the go.

Online Slots Selection

Whatever your taste in virtual one-armed bandits, MrO Casino can offer you a decent variety, of course, within the portfolio of one software developer. Still, the slot catalog is very diverse, both in terms of themes and reel mechanics. 

Progressive Slots: Megasaur, Aztec’s Millions, Cleopatra’s Gold, Spirit of the Inca, Shopping Spree II, Jackpot Pinatas Deluxe, Cleopatra’s Gold Deluxe.

Classic Slots: Double Ya Luck, 777, Magic Mushroom, Neon Reel 7s, Santastic!, Warrior Conquest, Wildfire 7s, The Three Stooges II, Santa’s Reel Wheel, Scuba Fishing.

Popular Slots: Egyptian Gold, Spooky Wins, 5 Wishes, Ninja Star, Samba Jackpots, Bubble Bubble 3, Cash Bandits 2, Ancient Gods, Witchy Wins, Princess Warrior, Gem Fruits, Shanghai Lights, High Fashion, Voodoo Magic, Legend of Helios, Triple Twister, Asgard Deluxe, Wu Zetian, Legend of the High Seas, Ghost Ship, Vegas Lux, Texas Tycoon.

Table Games Offering

The place boasts an excellent choice of blackjack variants and progressive poker, as well as video poker. At the time of writing this review, we did not spot any roulette game. As already said, this online casino does not offer live dealer tables.

Progressive Games: Caribbean Hold’em, Let’em Ride, Caribbean Stud, Caribbean Draw Poker.

Table Games: Blackjack Perfect Pairs, Baccarat, Tri Card Poker, 21 Blackjack, Suit’em Up Blackjack.

Video Poker: Jacks or Better, Joker Poker, Aces & Eights, All American, Bonus Poker, Deuces Wild, Bonus Poker Deluxe, Loose Deuces, Double Double Bonus Poker, Sevens Wild, Double Jackpot Poker.


MrO is a gracious host who greets all new quests with open arms and a generous welcome package bolstered by a huge bunch of bonus spins. While the sign-up treat is the same for everyone, the website’s promotional offering for existing players is built to cater to different gambling styles and, most importantly, bankrolls. 

But let’s start with their advantageous no-rules bonuses that have no wagering requirements, maximum cashout limit, game restrictions, and even maximum bet. Yes, you read it right, you can claim a deposit-match deal to play any game you like, and if you land some nice win, your chances to take it home are big. Because to make a withdrawal, you will only need to roll over your deposit and the received bonus amount once – to comply with the AML policy that requires all deposited funds to be put into play.

No-rules bonuses come in several variants and the percentage depends on the size of the deposit. Players can choose whether they want to go with $20 and get a smaller boost or deposit $100 and receive more bonus money. To make things even more flexible, such offers can be claimed twice per day, which gives punters numerous opportunities to adjust their gameplay. For those who want the casino to give them a much higher amount than what they have deposited, there are special High Bonuses available on a daily basis. Well, they do have playthrough requirements and a max cashout, which is totally understandable.

More perks come from MrO’s Voyage, a points-based loyalty program that rewards patrons for their betting activities. Apart from the possibility of earning comps and later exchanging them for cash, there is a spectacular Flash Cashback promotion and guaranteed monthly gifts. Depending on their loyalty status, players need to stake between $10 and $7 to earn 1 comp point while the exchange rate is 100 points for $1. Just a heads up, 100 is the minimum amount of points that can be morphed into cash.

The program has four levels - Optimist, Outstander, Opulent Roadster, and MrO’s Private Party, with the latter being by invitation only. As for the guaranteed monthly rewards, Optimists receive 100 slot spins, Outstanders – a $50 casino chip while Roadsters are entitled to a hefty $200 chip. Plus, there are various privileges such as higher cashout limits and personal manager.

Payments and Cashier

With a decent set of the most popular cryptocurrencies in the cashier, MrO Casino is a great choice not only for players who prefer traditional payment methods but also for fans of digital assets. Patrons who are thinking of switching to BTC or other coins but do not know where to start can take advantage of the site’s in-depth step-by-step guide, which will walk them through the entire process of setting up the coveted wallet.

Just a heads up, the minimum limit for crypto deposits is set at BTC 0.0003, but not below the value of $10. That means the casino will not process smaller transactions and, instead, will treat them as non-recoverable, which is general practice across the industry. In case you were wondering, sending extra funds to reach the threshold of BTC 0.0003 or $10 is not allowed. Also, it is highly recommended to always double-check the address you are sending your money to because there is no mechanism in place to reverse crypto transactions.

Below are some other key points to keep in mind for smooth banking at this online casino:

  • To request a withdrawal, players have to wager their deposits at least one time in full. Failing to comply with this rule, the casino reserves the right to charge a processing fee of up to 10% on respective deposits and withdrawals.
  • Players are eligible for one instant payout per day.
  • To withdraw winnings generated with the use of a no deposit bonus, customers who have not deposited at the website before, need to make a minimum deposit in order to verify their accounts.
  • Progressive Jackpot wins are paid out in monthly installments.
  • If not stated otherwise, winnings from bonus spins or casino chips are limited to $50.
  • Complimentary points are subject to a maximum cashout limit of 25x of the redeemed amount.


There is a lot to like about crypto-friendly MrO Casino, which makes a major effort to offer bonuses that are really worth claiming. In fact, the only con of this online casino is that it operates without a license. Other than that, everything looks great.
