21.co.uk sister sites 2025
Slot Boss
Most of the 21.co.uk sister sites serve a specific purpose, and that purpose is made clear from their name. We bet you can’t guess what the purpose of Slot Boss is? We are, of course, joking. Slot Boss is the most slots-centric of the sites on the LeoVegas Gaming PLC platform, focusing on spinning reels far more than it focuses on any other aspect of iGaming. As we go through the 21.co.uk sister sites, you’ll notice that most of them contain far more than meets the eye, but that isn’t true of Slot Boss. It has a live casino section, and you might find the odd scratchcard or instant win game here, but you won’t find bingo or sports betting, which are fixtures at other sites on the network. When you come to Slot Boss, you know exactly what you’re going to get – and that’s what so many of its players like about it. Slot Boss is unlike a lot of slots-focused iGaming sites in that it doesn’t offer any bespoke or exclusive games, figuring instead that players would prefer to have an enormous collection of titles from well-known providers to choose from. There are around two thousand online slots at Slot Boss, which isn’t the biggest collection we’ve ever seen, but it’s certainly far more than you’ll find at your average iGaming site. For all new players, first deposits are matched at 100% up to a maximum value of £150 and come with fifty free, wager-free spins on one of the site’s top games.
Pink Casino
During the past tens years we’ve seen something of a seachange in the world of online casinos and iGaming sites. While it was once fashionable to build and launch sites split along gender lines – bingo sites for women, slots sites for men – that isn’t the case anymore. Casino operators have learned that there are plenty of men who love playing bingo and plenty of women who love playing slots, so it’s becoming increasingly common to see new sites offer both in the same place. That’s left older casino sites like Pink Casino swinging in the wind a little because they’ve fallen behind the times. Pink Casino was the only one of the 21.co.uk sister sites that was “built for women,” but in an era where that’s no longer necessary, it’s looking for a new purpose. That’s why it’s recently been through a massive top-to-tail revamp – and it’s looking better than ever. Gone is the pink-on-pink colour scheme that used to welcome players to Pink Vegas. It’s now got a darker two-tone look that’s more in keeping with the rest of the 21.co.uk sister sites, with most of the site being purple, and pink used only for highlights. Now our eyes aren’t being scorched by the hot pink glare anymore, we can see that Pink Casino is second only to LeoVegas itself in terms of the number of things you can play and do at the site. If you want slots, you’ll find plenty of them, but you’ll also find a large selection of instant win, table, and live dealer games. Don’t worry if you loved Pink Casino the way it was before, though – all the bingo games that made it popular in the first place are still there, too.
LeoVegas
All of the 21.co.uk sister sites exist on the LeoVegas Gaming PLC casino network. This site is called LeoVegas. That means this is the flagship site of the network, but we suspect that most of you knew that already. LeoVegas is, after all, one of the most famous casino sites available to players in the UK. It’s not without good reason that LeoVegas has been named “Online Casino of the Year” no fewer than five years in a row at the Global Gaming Awards, with the most recent of those awards coming in 2022. For any casino site to win such a prestigious award once would be an honour. For LeoVegas to dominate the category for half a decade is unprecedented. Aside from being the flagship of the 21.co.uk sister sites family, LeoVegas is also the shop window. This is where the casino operator demonstrates the full range of its capabilities and showcases all of its wares. That means LeoVegas does everything. If you want to bet on sports, LeoVegas has a sportsbook. If you’re looking for bingo, LeoVegas has that too. From slots to instant win scratchcards or from table game simulators to table games with live dealers, LeoVegas covers every angle. If you’re moving on from 21.co.uk because you want something with more depth, you won’t find better than LeoVegas on this network. The only note of disappointment we can sound about LeoVegas is that its promotions are less than stellar, but even that’s a nitpick because they’re not terrible either.
Bet UK
When we were talking about LeoVegas a moment ago, we noted that it has a sportsbook. There’s only one other casino site among the 21.co.uk sister sites that offers a sportsbook, and it’s Bet UK. That statement is doing Bet UK a disservice, though – Bet UK doesn’t simply “offer” a sportsbook. Bet UK literally is a sportsbook, with sports betting at the core of everything that it does and a portfolio of slots and other casino games built around it. Of all the sports that Bet UK allows players to bet on, football is the one that gets the biggest share of the spotlight. Bet UK has always fancied itself as a football betting specialist, which is why the brand once sponsored the shirts of London club Queens Park Rangers. That deal is no longer in place, but the football connections remain because former England player Teddy Sheringham serves as the Bet UK brand ambassador. New players at Bet UK can claim £30 in free bets once they’ve registered an account, deposited £10 and then wagered it on sports bets. The £30 is paid out as a series of three £10 bets and comes with a couple of minor stipulations attached, so players are encouraged to read the fine print before accepting the terms of the promotion. As a Bet UK member, players have access to sporting tips from legends (Sheringham included) and a full calendar of horse racing and other sports to go with all the football action. If and when you want a break from sport, there’s a full casino attached to the site offering almost everything that you’ll find at Slot Boss.
