WinBig21 Sister Sites 2024

WINBIG21 IS NOT COVERED BY A UK GAMBLING COMMISSION LICENCE.

WinBig21 allows players from the UK to register and spend money. However, it shouldn’t be doing that. Neither the casino nor the company that operates it holds a UK Gambling Commission licence. Because of that, any UK-based player who plays at the casino does so at a great degree of risk to themselves. If disputes arise, there’s no regulator to step in and assist. As such, we can’t recommend the WinBig21 sister sites to any of our UK-based readers, and the information we provide here is intended for an international audience.

Lion Slots

Lion Slots logo

Lion Slots is, to the best of our knowledge, the only other member of the WinBig21 sister sites family. We say “to the best of our knowledge” because when it comes to casino network companies based in Curacao, it’s impossible to be sure. Operators based in the territory often leave their names off the casino websites that they run, and because the regulators in Curacao don’t publish registers in the same way that the UKGC does, there’s no way for anyone to know beyond all reasonable doubt that they’ve found every casino under an operator’s umbrella. There could be WinBig21 sister sites other than Lion Slots, but if there are, we’re unaware of them.

Lion Slots is, by some considerable distance, a better casino than WinBig21. It looks better, it has a better sign-up bonus, and the whole casino website looks classier and more professional. Silverstone Overseas Limited really went to town on this site, putting up to £9000 on the table in bonuses for new players and following it up with a series of VIP bonuses. The theme is well-integrated, including puns like “the mane event” to describe the loyalty bonus and using high-quality graphics. If it weren’t for the fact that it doesn’t have a UKGC license, we’d call Lion Slots great.

WinBig21 Review 2024

WinBig21, like a lot of casinos based in Curacao, is solely powered by slots and games from Rival Gaming and Betsoft. That makes the portfolio of entertainment available at the site somewhat limited, but you’ll be used to that if you’ve played at Curacao casinos before. It’s also a non-GamStop casino, which is something important to think about if you’re from the UK. The casino doesn’t have a theme, but it does a fair enough job of presentation with a modern style and a user-friendly interface. Given that it’s been online since 2012, it must be doing something right, so let’s see if we can find out what that “something” is.

WinBig21 sister sites homepage

WinBig21 Welcome Offer

Surprisingly, WinBig21 doesn’t promote its welcome promotion on its homepage, which feels like a mistake because it’s a fairly sizable package. Players can claim up to fifteen thousand pounds when they’re new to this casino, and yes, you read that right. It’s not without reason that the casino calls it “the big welcome package.” The catch is that you’ll have to make a lot of deposits to claim the full amount, and some of them are pretty big.

Let’s break it down for you. First deposits at WinBig21 are matched at 600% up to a maximum of £500 and come with three hundred bonus spins on selected slots. Second deposits are matched at 575% up to £500 and come with a further 250 bonus spins. From there, it’s a 550% boost and 200 free spins on deposit three, 525% and 150 spins on deposit four, and 500% and 100 spins on deposit five. You’re probably wondering how the casino came up with the £15,000 figure, and the answer is that the casino has a maximum payout of £2000 at each stage of the bonus. Yes, we know that doesn’t add up to £15,000, so we’re as confused as you are. In any event, each bonus has an x26 wagering requirement.

Ongoing Promotions

WinBig21 puts big promotions at the core of its identity and largely doesn’t disappoint on that front. At any time, a 525% matched deposit bonus might unlock while you’re logged in. The promotion can be claimed multiple times so long as you’re online and logged in when it becomes available. There’s also a 450% matched deposit up to a maximum of £500 that can be claimed once by every player, with an x30 wagering requirement. Further matched deposits are available. In addition to this, WinBig21 claims to offer weekly cashback on losses and a further promotion that it calls “Comp Point Madness,” but we couldn’t find any further information about these because the links that ought to take you to more info actually take you to the casino’s slots selection.

As if the offers above weren’t enough, WinBig21 has a VIP Club. There are five levels to the club (Bronze, Silver, Gold, Platinum and Diamond), with cash prizes for reaching each level, increasing amounts of weekly cashback and improved matched deposit incentives at every level. Diamond level is unlocked after reaching £5000 in lifetime deposits, which is a far lower price of entry to the top level than you’ll find at most casinos.

Pros and Cons of WinBig21

Pros: The promotions. They’re more generous and more accessible than the promotions you’ll find at 99% of other online casinos. Assuming the casino is as good as its word, there’s a massive sign-up promotion on the table and a well-engineered loyalty scheme, too.

Cons: There’s no banking information available at WinBig21, and we mean literally none. The casino doesn’t have a banking page or an FAQ, so we have no way of knowing how transactions work. Also, for all the big numbers available in the casino’s promotions, reliable information is hard to come by. The welcome promotion isn’t as big as it claims to be, and the links to further information about some of the promotions don’t work. To top it off, the casino is operating without a licence.

Top Games at WinBig21

We’ve already said that WinBig21 is served by just two providers, so it shouldn’t come as a surprise to you to hear that the full portfolio at the casino isn’t very impressive. On its homepage, it claims to have a big selection, but that simply isn’t true. However, the top slots at the casino include the likes of Klondike Gold, Mythic Wolf and Blazin’ Buffalo.

We’re focusing on slots because WinBig21 doesn’t have much to offer beyond them. While new slots are added fairly regularly, the casino doesn’t have any live dealer games or other attractions. There’s a limited selection of table game simulators and instant-win scratch games, but nothing you’d consider writing home about. To all intents and purposes, WinBig21 is a pretty small slots site with reasonably big bonuses, and it’s the bonuses rather than the games that serve as the site’s main attractions.

Withdrawal Processing and Support

We have almost no idea how WinBig21 works in terms of transactions. The lack of information provided on the casino’s website is a major worry. By not publishing a banking page or an FAQ, WinBig21 seems to have left players in the dark deliberately. There are some payment provider logos close to the bottom of the casino’s homepage, but if they represent the full extent of the options available, then they’re fairly limited. Assuming they’re correct, players can use Bitcoin, Litecoin, Dogecoin (yes, really), Ripple, Zelle, or bank transfers. The casino doesn’t offer any support for debit cards or e-wallets, which is a curious choice.

Customer Support and Licensing

Clicking on the “About Us” page at WinBig21 reveals that the casino has 24/7 live chat assistance available but also accepts enquiries via email at [email protected]. There isn’t a telephone number to call. Worryingly, the casino doesn’t appear to have any licences in place whatsoever. We already knew that it didn’t have a UK Gambling Commission licence, but it doesn’t even have a licence issued by the authorities in its native Curacao. Curacao-issued licenses aren’t held in very high regard, but they’re better than nothing and are very easy to obtain, which leads us to question why WinBig21 doesn’t have one. We’d also assume that the same is true of the WinBig21 sister sites. 

WinBig21 – The Verdict

WinBig21 goes big on its bonuses in the hope that they’ll distract you from how weak the rest of the casino is, but it doesn’t even manage to get that right. It promises a £15,000 welcome promotion, but it doesn’t deliver it. Some of the promotions listed on the “promotions” page have no further information available at all, so we can’t even be sure that they exist. Speaking of missing information, the casino offers no guidance about banking and doesn’t have a licence. Even if you’re the kind of player who’s happy to play at casinos not on GamStop and you’re on the hunt for new casinos in the Curacao region, there are simply too many red flags at WinBig21 to ignore. It doesn’t get our seal of approval.
