Bonuses And Promotions

One of the ways the best real money gambling sites differentiate themselves from lesser operators is in the bonuses and promotions that they offer their players. In that respect, Roaring 21 stands head and shoulders above most of its competition. Their main bonus, a 200% deposit match worth up to $2000 (and renewable 5 times for a total of $10,000 in slot free plays), is one of the most valuable in the business.

Software Overview

Roaring 21 exclusively employs casino games developed by RTG (Realtime Gaming), a software house founded in 1998 for the purpose of putting together audited, fair-gaming-compliant RNG (random number generation) betting applications. RTG is one of the most trusted development houses in the online gaming industry, and their systems are even used in various brick-and-mortar casino venues throughout the world.

Best of all, RTG products are all verified for compliance by third-party entities like Technical Systems Testing (TST), giving their players an added level of security and confidence.

Mobile App Interface

Roaring 21 is designed with on-the-go casino players in mind. While the site runs smoothly on any desktop or laptop computer, the emphasis is squarely on mobile casino gaming. Roaring 21 uses responsive design elements to suit the display of any modern smartphone or tablet, though it works best with iPhones, iPads, and Android handsets.

Because Roaring 21 is fully browser-based and made to run in Safari, Chrome, Firefox, and Opera (among others), you don’t have to download any special computer software, and there are no apps to install or update, either. Just bookmark the site, save it to your mobile device’s home screen, and you’ll always be one tap away from one of the best real money gambling experiences on the Internet.

Game Selection

With over 150 RTG games on hand (and new games being added all the time), Roaring 21 will have you howling with delight. While the site does not offer some of the categories that competing sites do (i.e. live-dealer table games and multiplayer poker tournaments), what it does, it does very well. From slots, progressives, table games, and specialty games, you aren’t likely to run out of ways to win at Roaring 21.

Support and Cashier

Because you can’t play if you can’t get your money loaded up into your account, every mobile online casino worth its virtual chips offers their members several banking categories for both deposits and withdrawals. Roaring 21 is no exception, and they’ve got more options than most.

For our money, Bitcoin/crypto is easily the best method available, as it’s the only way to quickly deposit and claim same-day payouts. However, for those that haven’t jumped on the cryptocurrency bandwagon, Roaring 21 also offers more traditional funding avenues. Best of all, none of Roaring 21’s deposit options comes with any added fees, which is a rarity among online casinos!

Licensing Information

Roaring 21 is a fully licensed online casino that operates out of Curacao in the Caribbean and is regulated by the Netherlands government. As such, the site is safe and secure for American casino players, and it also serves gamblers from a number of other countries.

2024 Roaring 21 Review Summary

Roaring 21, in our experience after playing with them since they hit the market in 2018, has all the bona fides you can ask for from a real money offshore casino. Utilizing the best mobile casino software and offering a robust suite of games, Roaring 21 boasts market-leading customer satisfaction and retention.

Of course, it’s not without its faults, the most pressing of which is the fact that younger players aged 18-20 cannot sign up and play. And unlike some competitors in the space, Roaring 21 does not offer a sportsbook or horse racing betting.

However, if you’re a casino gamer and are looking for a safe, secure, trusted establishment to enjoy some of the best fair-play-enabled slots, table games, and video poker, you really won’t find a better site with better bonuses and a friendlier staff of representatives. Roaring 21 is highly recommended.
