The Slot Boss Welcome Offer

  • 1st Deposit: 100% match bonus plus 50 extra spins
  • Minimum Deposit: £10
  • Promo Code: Need to opt in
  • Wagering requirement: 35x

When you sign up as a new player at Slot Boss Casino, you get a match bonus and 50 extra spins when you make your fist deposit.

You receive a 100% match on your initial deposit up to the value of £150, plus you pick up 50 extra spins on the Pragmatic Play slot game Big Bass Splash. To claim the bonus, simply click on the Opt In and Deposit tab under My Offers, and make a deposit of at least £10 within 7 days of opening an account.

Slot Games

Although the number of Slot Boss Casino slots is not as large as at some of the other sites that we feature here, the range of 600 games is still impressive.

As the slots are by so many different studios, you can find many of the most popular slot themes and titles, including big name games like Thunderstruck II, Immortal Romance, Esqueleto Explosivo and Narcos, as well as plenty of new release games.

One of the best features of playing here is the huge number of Megaways slots you can choose from. This includes games created specifically as Megaways games (including the exclusive Leo Vegas slot game), plus popular slots that have been adapted to feature the Megaways mechanic, like Gonzo’s Quest and Fluffy Favourites.

Casino Games

Live dealer games are hugely popular at Slot Boss UK, with games by Evolution Gaming, Playtech and On Air.

The range include multiple versions of all the classic casino table and card games, as well as a great selection of live game shows, such as Adventures Beyond Wonderland, Crazy Time, Monopoly Live and Football Studio.

You can also play a variety of online table and card games, including different varieties of blackjack and roulette, as well as Dragon Tiger and table poker games.

What Jackpots are available at Slot Boss?

The jackpot network at Slot Boss UK is called Gigantic Jackpots, and features progressive jackpot slots that are played across all the casino sites in the Leo Vegas network.

With a Major Jackpot that seeds at £4,500,000, there are plenty of opportunities to win big. To play, simply opt in when you open any of the selected Gigantic Jackpots titles; an additional £0.09 will be added to every spin to ensure that the progressive jackpot will grow quickly and reach a massive amount.

Other Games

Although slots and live dealer games are the main focus as Slot Boss Casino, there is also a good range of Slingo, scratch cards and instant win games, including titles such as Starburst, Who Wants to be a Millionaire, and Deal or No Deal.

Community and Customer Service 

As a mobile first slots site, the emphasis at Slot Boss UK is entirely on the excellent choice of games, and so it is not really a site where there is a strong sense of a playing community.

Community

  • Instagram
  • Facebook
  • Twitter

Slot Boss UK has a limited social media presence, with a Twitter account (@SlotBOSS_) and an Instagram page (slotboss), although these have both been dormant for some time, as well as a Facebook page that promotes safe gambling messages.

Given that the social media platforms are not especially active, we would recommend using the casino live chat or email if you want to engage with customer support.

Customer Service

  • Live Chat
  • Email
  • FAQs

You can engage with customer support via live chat or on email, although there is no option for making contact on the phone. The FAQ pages here are very extensive, and so you should be able to find answers to most of your queries using these.

In our experience, the customer services team responds in relatively quick time, and we have found them to be knowledgeable and helpful.

Slot Boss on Mobile

Slot Boss Casino is a mobile first site and offers a huge choice of 600+ games (including slots and live dealer games), a well-designed and easy to navigate UI, and an overall enjoyable playing experience.

If you are an iPhone or iPad user, you can download and install a free Slot Boss app from the App Store (search for Slot Boss: Online Slots). There is no Android Slot Boss app, but this is not a problem, as games can still be played directly in the browser of your phone or tablet.

Should I Play at Slot Boss?

The overall mix of the slot games at Slot Boss UK is what makes this an enjoyable site at which to play. With games by a mix of developers, you can play the best-known slots while also getting the chance to explore a variety of new release games. However, in our view the highlight is the large number of Megaways slots, plus the chance to be a part of the Leo Vegas progressive jackpots slot network.

Alternatively, if live dealer games are your thing, then you’ll be impressed by the Slot Boss selection. In particular, the range of live game shows means there are always plenty of entertaining options open to you.
