Play the Best Online Casino Games at Slot Boss

Slot Boss is known for the huge selection of slots available, provided by the world's most innovative and creative gaming designers. The gaming giants we work with allow us to provide the most popular and innovative online slots in the UK, establishing Slot Boss as one of the leading online casinos in the United Kingdom! It's not just standard slots that we have available though.

Looking for the best Jackpot games where the potential maximum win is improved? Jackpot games have the same look and feel as a standard casino game, but the main difference is that it's plugged into a Progressive system, meaning that the main jackpot prize is increased with every spin.

We might boss slots, but there's much more to get involved in when you look around the site. However, some fantastic news is that Slot Boss is now one of the top UK sites for Slingo. Slingo takes some of the best aspects of slots and some of the best aspects of bingo and combines them into one of the greatest creations on Slot Boss. We definitely recommend trying out this style of game if you haven't already.

Here at Slot Boss, we appreciate casino games that really stand out from the crowd in one way or another. Whether a casino game is simply ahead of its competitors or whether creators have taken a risk and stepped outside the comfort zone of casino gaming.

In the modern online casino era, games such as Rainbow Riches and Starburst will always be favourites amongst the community, and rightfully so, but we have found that this year some games have risen from the pack and really challenged the dominance those two have had in recent years. The hunt for the legendary wealth of Egypt has led to not just being one of the most well-known Queens of ancient Egypt, but also one of the most well-known games at Slot Boss. Meanwhile, the figures of Leprechauns and Genies have attracted players worldwide as Rainbow Jackpots and Genie Jackpots quickly rose up alongside. New to MEGAWAYS games? Learn how to play MEGAWAYS with our guide.

Our selection of casino games also extends to live casino, with the option to play popular games such as blackjack and roulette. Each of these includes live dealer gameplay with interactive features and chat functionality.

What Are The Most Popular Casino Games at Slot Boss?

Slot Boss is brimming with classics and modern casino games alike. We are a UK-based online slot brand, but we have games from the biggest international providers. First up is the amazing Starburst from NetEnt, which has been hailed as the greatest and most popular casino game of a generation, part of a group that we like to call the 'Golden Oldies'. In the same bracket is the hugely popular Rainbow Riches, so take a trip toward the Emerald Isle for Free Spins and more. Egyptian-themed games are some of the most popular on Slot Boss, mainly because casino floors in Vegas entertained punters with these games before they transferred to online sites. Of course, you can play these here, as well as revered games like Book of Dead and Book of Ra.

Working with gaming giants like Microgaming, NetEnt, Red Tiger, Blueprint, and many more, allows us to offer our loyal customers a first-class online games selection. It's our passion to provide the greatest gaming experience, so our game grid is updated weekly with new releases, but we have the classics available too. You could play the tumbling reels of Gonzo's Quest or Blueprint's Fishin’ Frenzy MEGAWAYS. Egyptian games are really popular here, with Cleopatra being the most well-established.
