Slot Boss sister sites 2023 logo

Your choice of Slot Boss sister sites will be dictated by what kind of casino site you’re looking for. If you’re looking for slots – which would make sense, given the casino you’re coming from – probably won’t be your favourite of the options available on the LeoVegas Gaming PLC platform. This, as is all but confirmed by its name, is an online casino that’s all about table games. It’s especially about card games and showcases the live dealer experience above all other things. You’re welcome to play card and table game simulators at if you wish, but the site would prefer you to pit your wits against live dealers in the many live-streamed titles that it offers from the likes of Evolution and Pragmatic Play.

While blackjack, poker, roulette and other traditional card and casino games account for most of what’s on offer at, that doesn’t quite tell the whole story. Most modern casinos that offer live dealers also offer live game shows, and doesn’t disappoint in that regard. All the latest game show titles from Evolution, including Dream Catcher and Crazy Time, are present and correct in the games portfolio. In addition, there’s a selection of online slots available, too. While that means you could find more of the same here if you moved straight from Slot Boss to, in practice, you’ll probably find more of what you’re looking for at one of the other Slot Boss sister sites. All of the sites on this platform offer slots to some extent, but some do a better job of it than others.

Bet UK logo

We’re getting the Slot Boss sites you’re less likely to be interested in out of the way before we turn our attention to those that you’re more likely to be enamoured by. Bet UK, like, has a portfolio of slots and traditional casino games to offer you. Also like, slots and traditional casino games aren’t really the casino’s area of expertise. Bet UK is a sports betting site. In real terms, it’s a football betting website, with all other sports sharing second billing outside the spotlight that Bet UK places on football. Even the Bet UK brand ambassador is a figure from the football world – it’s Teddy Sheringham, who’s famous for his exploits as a striker for Spurs, Manchester United and England during the late 1990s and early 2000s.

The sportsbook at Bet UK is the same as the one you’ll find at LeoVegas, so there’s nothing unique about Bet UK if you’ve already visited and played at the flagship of the Slot Boss sister sites family. Not everyone is a LeoVegas fan, though, so if you’re partial to the occasional flutter on sport and you don’t mind digging through the sub-menus to find the slots and other casino games you’re interested in, Bet UK could be the right choice for you. There’s a downside to playing slots at a sports betting site, though – most of the promotions at Bet UK are tailored to sports bets rather than slots, so you won’t find many perks to go with your preferred form of iGaming.

LeoVegas logo

Most people looking for Slot Boss sister sites will be best served by LeoVegas. That’s not a dig at the other casinos on this platform – it’s just that LeoVegas is the casino site that LeoVegas Gaming PLC gave its name to. It’s the site that the operator is most proud of and, figuratively speaking, the captain of the ship. It’s also one of the UK’s most popular casino sites and has been recognised for its outstanding quality several times. LeoVegas was first named “Online Casino of the Year” by the Global Gaming Awards in 2017 and went on to win the same award at the next four ceremonies. That doesn’t happen by accident and can’t be called a fluke. LeoVegas is the real deal and is the envy of countless other casino operators.

What is it that makes LeoVegas such a big deal and won it so many awards? It probably comes down to the sheer range of options available at the site. As we mentioned while we were talking about Bet UK, LeoVegas has a sportsbook. It also offers every online slots game you’ll find at Slot Boss, plus a few more. Virtually all the casino games at are available at LeoVegas, too. We’ll get on to Pink Casino in a moment, but Pink Casino is best known for its bingo features, and all of those bingo games can be played at LeoVegas. No online casino truly does everything, but LeoVegas gets about as close as it’s possible to get.

Pink Casino logo

We’ve just made it very clear that we think LeoVegas is the best of the Slot Boss sister sites, but that’s not the same as saying that the other casinos don’t have anything to offer. Pink Casino is probably second in the pecking order behind LeoVegas and has come on leaps and bounds in recent times. Pink Casino was once a “women only” casino site with a pink colour scheme so bright it almost made it necessary to wear sunglasses to access the site, but that changed in 2022 when LeoVegas Gaming PLC decided to widen the casino’s appeal. It has a new logo and new colours, and it’s got an expanded gaming repertoire to go with the new look. The bingo games that Pink Casino built its reputation on are all still there and all still playable, but they’ve been joined by much more.

The idea that women don’t play slots is deader than disco, so Pink Casino now has access to the same portfolio of popular online slots as Slot Boss (and, for that matter, LeoVegas). Almost the entire range of live casino games that offers has been added to the Pink Casino catalogue, too. The only difference between Pink Casino and LeoVegas, other than the different colour schemes, is that LeoVegas offers sports betting, and Pink Casino doesn’t. That’s probably a hangover from Pink Casino’s “female interest” days, but don’t be surprised to see sports betting added to the Pink Casino proposition in the not-too-distant future.

Slot Boss operator – LeoVegas Gaming PLC

leovegas casinos logo

Slot Boss is on the LeoVegas Gaming PLC network, which means it belongs to one of the highest-profile casino operators in Europe. The owners of the Slot Boss sister sites are based in Stockholm, Sweden. The fact that LeoVegas is a Swedish company will come as a surprise to at least some of the people reading this, but that’s partially down to the fact that the company has such an enormous presence elsewhere. You’ll find LeoVegas offices in Poland, in Italy, here in the UK and in Malta – although the Maltese office is only really there so the company has a base for tax purposes and so it can hold a Malta Gaming Authority licence. The most recent move that LeoVegas made in Europe was to gain access to the Dutch market, which happened with the granting of a new licence in 2021.

The future of LeoVegas might have more to do with the American gaming market than the European one. As of September 2022, LeoVegas Gaming PLC is the property of MGM Resorts International, which paid more than half a billion pounds for the privilege of owning the LeoVegas name and all of its assets. MGM Resorts International owns hotels and casinos all over the world but is synonymous with Las Vegas, Nevada. The ongoing relaxation of the American market might mean that MGM plans to launch LeoVegas stateside soon – or, on the other hand, it might have seen LeoVegas as the perfect cherry to pick in order to gain a better foothold in Europe.

Slot Boss Sister Sites Welcome Bonuses

Welcome promotions at the Slot Boss sister sites are much of a muchness, with the same promotions (with a couple of minor tweaks) appearing at each of the sites in the family. The main welcome promotion at Slot Boss is a 100% matched deposit subject to a cap of £150 and tied to a wagering requirement of x35. That’s about average in the context of UK online casinos as a whole. This promotion comes with fifty free spins on (at the time of writing) Big Bass Splash. The spins don’t have any wagering requirements attached, so if you win anything from them, it’s paid as cash and yours to keep. You only have three days to use the spins and seven days to clear the requirements on the bonus funds, though, so act quickly.

Slot Boss also offers a secondary welcome promotion for anyone who isn’t interested in slots, which is up to £50 as a matched deposit to use on casino games plus £6 of free casino chips to redeem on certain games. It would be odd to go to Slot Boss if you’re not interested in slots, though.

Other Promotions

Ongoing promotions are a weakness across the entire Slot Boss sister sites family. The welcome you get at Slot Boss is quite warm, but the further perks the site offers are tepid at best. Most of the additional promotions at Slot Boss are seasonal or short-lived, so be sure to check if anything has changed since we wrote this review, but there’s not much to write home about at the moment. There are prize draw offers, including one for up to £10m, and the offer of twenty free spins on a specific slots game for anyone who deposits £20 and wagers at least x2 that amount on slots within three days. The offer is tied to whatever the Slot Boss game of the week is.

Top Games at Slot Boss

It would be weird if the top games at Slot Boss weren’t online slots, so we’re pleased to report that we don’t have a tonal mismatch in that respect. You’ll find the featured games at this casino in the spotlight in the middle of its homepage. If you’re a big slots player and you know your Megaways slots from your five-reelers, you’ll know all of the slots that you’ll find there already. If we tell you that Rainbow Riches and Starburst are both featured games at Slot Boss, you’ll see what we mean. Starburst, with its other-worldly atmosphere and sticky respins, might be the most popular online slots game of all time. Rainbow Riches by Barcrest changed the game for Irish-themed slots when it was released and is now the benchmark by which they’re all measured. Most of the other slots here are classics, too, like the Egyptian-themed Book of Dead by Play’n Go. The only exceptions to the “classics” rule tend to be the games of the week, which are usually new arrivals at the site.

Licensing and Customer Support

For players in the UK, Slot Boss is covered by the licence that LeoVegas Gaming PLC holds with the UK Gambling Commission under account 39198. The operator was fined by the regulator in July 2022 after being deemed guilty of breaching licence conditions regarding how to interact with customers and how to prevent money laundering. An official warning has been attached to its operating licence, and a fine of £1.32m was handed down. Aside from its FAQ section, Slot Boss offers email support and live chat. Telephone assistance isn’t offered.

Withdrawal Speed and Support

LeoVegas Gaming PLC offers the same deposit and withdrawal methods across all the Slot Boss sister sites, which is a shame because it’s not a great range of options. Mastercard and Visa are the only debit cards accepted, and beyond that, your only options are PayPal or bank transfer. Withdrawals can take up to five working days to process once a request has been made.

Final Thoughts on Slot Boss

With two thousand slots to choose from, Slot Boss delivers on the promise it makes in its name. Where it fails to deliver is in two key areas – promotions and payment processing. A few perks for loyal players and a faster route for withdrawals would make this a far better place to play.

Slot Boss Sister Sites Player Reviews

Here are the thoughts of your fellow players about Slot Boss. The reviews are all real, but we’ve paraphrased them to keep them brief.

Of all the slots sites on the internet, I hate Slot Boss more than any of the others. They’re crooks, and they do whatever they like and never face consequences for it. Bonuses never get credited, and when they do, they don’t work. I’ve lost hours of my life trying to speak to customer support, all to no avail. Dave, November 2nd 2022. Source – Trustpilot.

Slot Boss stole my winnings. I’ve verified my account and did everything they asked of me, but they closed my account anyway and kept the £800 they owed me. I’ve asked for a review and have been told it could take two weeks. Dave, October 20th 2022. Source – Trustpilot.

I’ve sent this website more than ten forms of ID and proof that I own my bank account. They accepted it and then locked me out of my account anyway. I’ve had no response to my written complaint, and they won’t release my winnings to me; I can’t believe they’re allowed to get away with this. Lavinia, October 19th 2022. Source – Trustpilot.

I should have read the reviews before I played here – Slot Boss doesn’t pay out. They’re trying to tell me to open an account with PayPal so they can process my withdrawal. I’m 60, I don’t know what that is, and I don’t want to do it. They owe me two grand, and there seems to be no way to get my money. David, September 12th 2022. Source – Trustpilot.

Honestly, this is a sketchy casino. I spent £400 playing Stampede and only got a couple of small bonuses. It’s supposed to have 95% RTP, but it played like it was closer to 50%. The lesson I’ve learned is not to play on small casinos because they’ll just rip away your balance. DY, September 6th 2022. Source – Trustpilot.

Slot Boss is a very reliable casino; I’ve been playing here for years because the site offers almost instant withdrawals and loads games quickly. It’s just a brilliant site all-round. Steph, September 6th 2022. Source – Trustpilot.
