Winbig 21 is an online casino that aims to provide the thrills of Vegas-style gaming to players sitting at home. They are powered by Rival Gaming, one of the industry's most well-known software providers. The casino has been officially licensed by the jurisdiction of Cyprus. 


The selection of games at Winbig 21 includes an impressive variety of slots. Players have three different slot categories to choose from: conventional three-reel slots, bonus video slots, and interactive i-slots that take standard video slots and really bring them to life. Each of the games is available at virtually any bet denomination.

In addition to slots, Winbig 21 features a number of different table games. Try your hand at single-hand and multi-hand blackjack, roulette, baccarat, red dog, craps, war, and Caribbean Stud Poker. These games all feature realistic animations and a wide range of betting options to accommodate all types of players.

The video poker selection at Winbig 21 is large enough for most players. They offer a total of seven different variants: Jacks or Better, Tens or Better, Aces and Faces, Deuces Wild, Joker Poker, Deuces and Joker, and Double Joker. These games all feature top-notch graphics and generous paytables.


We have found that Winbig 21's support team is satisfactory for most player needs. Get in touch with a representative 24/7 through a variety of different methods, including live chat and UK phone. You can also send the casino an email and expect a reply within 24 hours in most cases.

Security and Fairness

The Winbig 21 server has taken the necessary steps to keep you safe while playing. Most importantly, any sensitive data you furnish to the casino for the purpose of registering your account or banking is kept safe with SSL encryption. This technology makes it nearly impossible for anyone to take your personal or financial information.

The Rival Gaming platform has been proven fair by numerous independent audits. Unfortunately, the Winbig 21 website does not provide this information. Although we have plenty of evidence to show that the games are fair, it would be much better if Winbig 21 provided this information themselves.

Absolutely nothing, I would NOT recommend this casino to anyone.


They will spam your email to death. I have unsubscribed many times and also marked their mail as spam and still their spamming mails about bonuses etc keeps coming, this makes me question how this casino manage get around the spam notice (they use the same emails every time) and their unsubscribe page clearly lies when they say you have been unsubscribed because the emails (read 'spam) keeps coming.

I've wrote emails to them many times asking them to close my account and to stop sending me emails but no response or confirmations - I have tried to send emails to every email address noted on their site but nothing.

I advice all people to take a look at what players have to say about this casino and all the complaints and then decide if this is a casino you really would want to trust your money with.

There are (definitely) much better and more reliable casinos out there, and so if you want to avoid frustration, being ignored and having your email being spammed then choose another casino.

Few days ago I joined WinBig 21 casino. They are powered by Rival software and I found a no deposit bonus offer so I decided to give them a try with a freebie, although I noticed they have many complaints on AskGamblers. I tried to register from an affiliate link, but it didn't work, so I just signed up, hoping to see a no deposit bonus in the cashier, as it usually happens. After registration, I saw that the cashier was only full with deposit bonuses, large deposit bonuses like 500% match and even more. Maybe I'm just odd, but bonuses like that often make me think the casino won't be trustworthy.

Then I decided to speak to live chat, as I wasn't gonna deposit there just yet. Luckily I didn't have to wait at all and after I told the bonus code to support and refreshed the page, I saw that my balance was credited with 319€. I am quite sure it's the biggest no deposit bonus I've ever received. But of course there was a catch.

It was a multi stage bonus with 2 stages. In the first stage I should wager 700€ within 60 minutes, then I would need to make a deposit and then wager everything again. But it gets only worse and worse, the maximum withdrawal would be only 342€ which is my initial bonus amount + 25€ deposit I would need to make. Honestly I felt like laughing after this conversation with live chat, this was one of the worst bonus offers I was given. I read that after the first stage the bonus would be deducted and if I had less money than the bonus amount, I wouldn't be able to get to next stage..So complicated and unnecessary.

Needless to say that my time at Winbig 21 was shorter than those sixty minutes for 1st stage! Most Rival casinos offer no deposit bonuses that just have huge wagering requirements, but in this case there were so many little hidden details in this bonus that made it absolutely undesireable. At some point I asked another question to live chat and no one answered to me anymore. Although the lobby and game selection looked decent, nothing else was decent about them unfortunately and I'm sad I wasted my time there at all.

Why i thought that Winbig 21 are more older casino and they were only 3 years at the online market, still don't know, having some Cyprus licence, which must admit didn't play at casinos with that sort of jurisdiction. I can't say I had some bad experience with this guys, but relatively new casino with tons of complaints, it certainly doesn't makes them casino of the year, is it ?

From all I have read, they are really tough of giving money, so many complaints and all connected for paying.paying. That is the reason I don't play at their casinos, because Rival are well known to be rogue ones.I mean why should I waste my time and money and having the possibility to win and after to beg for my money, I don't think that will happen, actually I am not some fan of their games, so that won't happen for sure.

Seeing all this complaints at AskGamblers site and most of them haven't been resolved, actually no one even bothered to have a look and answer those players, so my opinion, very irresponsible management. So back then when I opened my account there, honestly I didn't know anything about them, but as the time goes I can see they become one of the rogues casinos online.

They were running some promo of free play one hour, but never interested in that kind of multi stage promotion bonuses and the other one was 21$ free chip with X 72 wagering requirements. I remember I played Gnome Sweet home, slot, actually that was first Rival game I played and the free chip finished very quick.

Being my first Rival game, at the beginning I knew I won't like this games, I still fancy more Microgaming and Netent games, believe those games are more interesting, definitely with way better graphics and much more to give, so I will stick to my favorites and as for this Rival, I might play them as free spins or chips, but in nice casinos, not as this one.

Good luck if playing here, you certainly will needed it a lot!
