WinBig21 Casino website has a variety of gaming options, a large game collection, and an interesting look. The site is quite simple and straightforward, meaning that players will have no problems finding and playing their games.

It has a relaxing blue theme, a great layout, and quick response time. However, the casino site design could use some slight updates and include a virtual lobby, as it appears that the instant play casino isn’t working at the moment. However, the software and mobile versions run smoothly without any issues. It will only take a few moments to download the software and choose your game. We’ve tested their software for this review and found that it has a great blue/yellow design, along with fast loading times, crisp game graphics, quick navigation, and lag-free gameplay.

Furthermore, this casino allows players from the USA, and it has had some time to establish a good reputation since it was launched in 2012. And in terms of a first impression, the casino has plenty of gaming options, 24/7 customer support, a variety of bonus offers, a VIP program, and many banking options. Additionally, the online casino definitely lives up to its name by offering progressive jackpot games. The current prize pool is over $320,000 in total, which is enough for a casino of this size.

Furthermore, the casino website displays all the relevant information you need to make sure that it is a reliable gaming site. There is a responsible gaming policy, as well as a clear terms and conditions section. As mentioned, the casino is licensed and regulated by the jurisdiction of Cyprus.

In terms of casino games, there is a broad choice of slot games, including interactive slots, 3 and 5-reel slots, and more. Moreover, the specialty, video poker, and table game sections feature some classic titles and provide some entertaining options. As stated previously, all the games at this casino are made by Rival Gaming. This software provider is well established in the industry and offers some great quality casino games. With almost 200 games, the casino will suit most players’ needs.


But is WinBig21 a trustworthy casino? To begin with, it utilizes SSL encryption to make sure your private details and banking information will stay protected. Furthermore, Rival games in this casino are frequently tested by independent parties to prove their fairness. However, one review portal criticized the casino and claimed a rogue group operated it, but that was mere speculation. There is no proof that confirms this casino is tied to any rogue group, so you can be sure WinBig21 is safe to gamble at. This is a fully regulated and licensed casino. Even though the Cyprus license is less common in the industry, that doesn’t make it less any legitimate.

What is more, we have looked on several online portals to see what real players thought of the site, and there were many satisfied players. Some have complained about the fact that the casino sends a lot of promotional offers via e-mail, but we believe that’s a good thing since the casino wants to keep players updated and offer them good promotions. Overall, the casino sticks to a high standard, and it is a decent and trustworthy place to spend real funds at.

As mentioned, the casino offers 24/7 customer service. You can contact them using e-mail, toll-free phone number, and live chat. For some countries, the toll-free number might not be available, so it’s best to use live chat. We attempted to use the live chat option on the site, but unfortunately, it didn’t work. However, it did work in the casino software, and we got an extremely quick reply when we asked about the welcome offer. The casino rep was polite and gave us all the information quickly. Overall, we were very pleased with our experience with customer service. It’s safe to say that you can expect them to answer all your questions.


Overall, WinBig21 Casino has a good game library with a lot of different options. It’s a shame that the instant-play feature didn’t work for us, but the software version worked perfectly. The lack of instant-play could be due to a technical glitch, so it’s best to check if it works from your region if you prefer to play casino games in your browser.

Furthermore, the casino has a good reputation, some large bonuses, and a great customer service team. The bonuses are bigger than in other casinos of this size, so users who are interested in big bonus offers should definitely consider this casino. In conclusion, WinBig21 is a good gambling site where you can spend real money and have a great gambling experience.
