And one look at the site will likely convince you of this. Everything about it looks refined and crisp, with bold hues and brilliant graphics. On the homepage, the background image portrays the 21 theme repeatedly at the center of slot reels. Similarly, the ‘o’ in Roaring is an elegant slot reel. It is evident that they are trying to recreate the atmosphere of the period that informs their name. Its design successfully captures the mood, and makes you feel like you just walked into the Ritz. The theme colors are dark blue and gold with white lettering scattered here and there to captivate attention. Its total jackpot value takes center stage in extra large font that is impossible to miss. Below this they highlight the most popular games with jackpot amounts (for those that have jackpots). Their extensive reward program also has significant prominence, once again, an alluring feature of the service. In much the same way as they place emphasis on the visual appeal of the site, its functional aspects are also top-notch. It has clear links directing you to various important areas such as security, responsible gambling and much more. Generally speaking, it is a great design that offers the perfect mix of function and aesthetic appeal.Roaring 21 Software Providers The casino gets all its games from a reputable software provider, RealTime Gaming (RTG). RTG supports hundreds of games reflecting Vegas inspiration for instant play or download. They are highly renowned for the creation of realistic games. This comes as no surprise given that they have been at it since 1998, and they are one of the oldest and most established industry names.Games at Roaring 21 Like our Bitstarz review, when it comes to games, this online casino excels in more ways than one, as they pit quality over quantity and make a success of it. The fact that all the games on this site come from RTG is in itself a major advantage. Their games are known to load with ease and offer top-notch graphics on a user-friendly interface. However, having games from a single provider also means that their collection is quite limited. In comparison to other casinos which offer thousands of options, Roaring 21 has less than 300 games in total. But on the bright side, these games include lots of unique and original titles that you may not find anywhere else. They have a total of 5 game categories including:ProgressivesSlotsSpecialtyTable GamesVideo PokerYou might also appreciate the new games section, which always features new titles from the various categories.

But do they live up to these ideals? The gambling site operates under licensing from Curacao eGaming. As they explain under their Fair Gaming section, being fully licensed requires that they maintain the required high standards of compliance. Part of this involves regularly monitoring outcomes to ensure fairness. In addition to this, its random number generator is regularly (every month) audited for fairness by Technical Systems Testing (TST). These independent audits are aimed at ensuring that all players get a fair chance to win the jackpots. TST is an internationally recognized body mandated to carry out this role. In the spirit of transparency, they reveal their RTP, which is currently 94% on the Real Series Video Slots. That is exceptional as most casinos do not provide this information. Furthermore, the casino uses the latest software available in the market to secure players’ information. Using 128-bit Secure Socket Layer (SSL) encryption technology, they make sure that user data is securely transferred over the internet to their servers. In turn, the server has the protection of the latest firewalls.Roaring 21 Customer SupportRoaring 21 also excels in customer support as it takes a multi-pronged approach to put its users at ease.

A third option is to reach them on the phone, which is also available round the clock.
