GrandRio Casino is a NetEnt and Microgaming casino themed after the festive Rio de Janeiro Carnival. In addition to its slots and other virtual table games, there's also offer an Evolution Gaming live casino. Many of its titles are available in both standard and touch versions. GrandRio Casino is available in both English and Russian and is licensed under the government of Curacao. 

Restricted Countries and Territories

GrandRio Casino does not accept players who reside in the United Kingdom or the United States.

Virtual Games

The main casino lobby at GrandRio Casino is split into two sections: one for Microgaming titles and one for NetEnt titles.

The Microgaming section features the company’s most prominent slots as well as their lesser-known titles, including Immortal Romance slot, Ariana slot, Thunderstruck 2 slot, Avalon II slot, and Savanna King slot. It even features Mega Moolah slot, one of the world’s largest progressives. Players here will also find several Blackjack and Roulette variants plus a number of specialty games like Max Damage and the Alien Attack and Triangulation.

The NetEnt section is also highly varied, featuring most of the company’s games (except network progressives). Slots in this portion of the casino include Dazzle Me slot, Gonzo’s Quest lot, Jack Hammer 2 slot, South Park slot, and Piggy Riches slot. Players here will also find Blackjack, Roulette, Keno, and scratch games.

Live Games

Although GrandRio Casino’s virtual table games are good for quick play, the live casino does an excellent job of providing that immersive table game experience. It is powered by Evolution Gaming and features real games of Live Blackjack, Live Roulette, Live Baccarat, and Live Casino Hold’em. These games are all dealt to professional standards in real-time from an actual casino studio. Players can even interact with each other and the dealer.

Mobile Gaming

A number of GrandRio Casino’s slots and other casino games are available to players on the go. The mobile casino can be accessed on virtually all mobile browsers, including those found on iOS and Android smartphones and tablets. No app downloads are required to start playing.


Players who need instant assistance can contact GrandRio Casino through a live chat feature, however, there are short technical breaks that tend to occur. Alternatively, players also have the option of emailing the casino, although it may take some time for an agent to get back depending on the volume of inquiries.

Security and Fairness

GrandRio Casino protects players from having their personal and financial information compromised by using SSL encryption. This technology converts all private data into unreadable strings of text that cannot be decoded. It’s the same protocol used by all leading online companies.

Both the NetEnt and Microgaming platforms have undergone significant testing over the years. These independent tests show that the games are powered by a genuinely random number generator (RNG), leading to unbiased and fair results for all players.

Don't know what to say...just want answers, hope this will help!


Don't know what's going on with this casino, sent 2 e-mails to support trying to figure it out, but no reply so far! The website is Under Maintenance for 72 hours now! This is not normal, if it was a simple update it could be done in 24-48 hours tops!!!! And why the hell they don't answer to e-mails?

I'm starting to feel cheated, this casino has the TRUSTED mark from AskGamblers... C'mon AskGamblers you should do a good background check before giving a Trusted status to any casino!
Dear Joao!

We would like to ask you not to worry and to be patient as you will be able to request for withdrawal as soon as the website will be opened. Our team hopes for understanding.

Has a fake license from Curacao. Rio removed all logos and put their site under maintenance after confronted about this.
Good selection of games.


Makes excuses not to pay players - your money is in jeopardy.
Hello, Mikko!
Thank you for your opinion that is unfortunately not correct enough and a kind of offensive for us. As you know, our website is currently on maintenance due to technical updates and a license renewal. We always value our players and our reputation and can not allow ourselves to have a fake license. All the information on it can be proved by Curacao gambling commission. Your withdrawal was not unfortunatelu proccesed due to severe violation of our casino's terms that was confirmed by all the materials in the complaint published by you on this website. Our casino together with Askgamblers consider this complaint resolved and all the claims concerning this issue are not legal. We are ready to consider anyt other consistent and objective reviews if there are any.
