Slot Boss Casino Review

Slot Boss is a licensed and regulated online casino owned by LeoVegas Gaming PLC. The operator was originally established in 2014 as part of the Alderney-based company Intellectual Property and Software Ltd (IPS). In 2018, LeoVegas Gaming PLC purchased the casino in a deal worth a staggering £65 million.  Slot Boss sister sites now include Bet UK, Pink Casino, LeoVegas and 21.co.uk.

During our review, we found a catalogue of 580+ casino games on this platform. While these sound like they are fewer than most competing sites, most are high-quality games, including the best slot games, latest video slots, classic slots, gaming tables, instant win games, roulette, blackjack, three card stud, dream catcher, live casino and jackpot games. 

Review Results

Slot Boss Game Selection

As we said, Slot Boss went for quality over quantity in their slot game selection. We counted up to only about 300 slots in this casino’s lobby. Even so, we were thoroughly impressed that all of the games are powered by some of the biggest software providers in the industry presently.

Here, you can get started with classic slot games like Starburst, 9 Masks of Fire, Deadwood Slot and Rainbow Riches: Reels of Gold. You can also get creative and try out great branded games such as Guns ‘n Roses, Kiss and Ted

Whether you prefer the Egyptian theme such as Cleopatra slot, or something else like Irish, Fantasy Sci-fi theme or retro slots, you will find something that catches your eye at Slot Boss. 

Does Slot Boss Offer Progressive Jackpot Slots?

Some of the biggest wins at Slot Boss are courtesy of the Blueprint Gaming’s progressive jackpot slots. These progressive jackpots feature Gold, Silver and Bronze levels. What this means is that there are minor and mini jackpots awaiting players if they don’t land the major six-figure jackpot. 

Not interested in progressives? No problem. Slot Boss offers plenty of regular jackpot games including The Goonies Jackpot King, Wish Upon a Jackpot King, Cop The Lot, Reel King Mega, Top Cat, Mega Dragon, Volcano Queen Diamond Spins, Deal or No Deal, Super Spinner Bar-X and Ted Jackpot King.

Can Players Demo the Slot Games for Free?

Regrettably, Slot Boss does not offer demo versions for any of its games at this time. But with a no-deposit bonus credited to you after successfully creating an account, what do you need a demo version for?

Slot Game Providers & Software

There is an impressive range of slot game suppliers at Slot Boss Casino. We found plenty of games with different thematic varieties and gameplay styles from tried-and-true software studios like NetEnt, Microgaming, WMS, NextGen, Realistic Gaming, Blueprint Gaming, IGT, ELK Studios, Big Time Gaming, Red Tiger and iSoftBet among others. 

Slot Boss Live Casino section is powered by Evolution Gaming. We were pleased with the immersive camera angles, smooth gameplay features and theme lounges. The casino also works with professional live dealers that lend a modern twist to the Slot Boss’s live casino section. 

Slot Boss Design & User Experience

The Slot Boss website is colourful, bold and user-friendly. The first thing you will see at the top-right is a search button that lets you search for your favourite game or provider.

Right below the search button are tabs that take you to Home, Promotions and Casino. The main games lobby is categorised into Slots, Jackpots, Table Games, Live Casino and Instant Win. Scrolling past, you will come across links to Safer Gambling, Block and Help.

The Deposit Offer and Join buttons are found in the upper-middle of the screen. Right below this, you will see casino games split into Featured Games, New Slots & Games, Table Games, Live Casino Games, Jackpot Slots, Slingo Games and High Street Games.

The right-hand end of the Slot Boss website also hosts the Login and Join buttons. Finally, information about game suppliers, banking methods, licenses, terms and conditions, and more can be found at the very bottom of the page.

Slot Boss Casino’s Mobile Experience

A mobile-friendly site, Slot Boss supports instant in-browser play across devices. Moreover, there is a Slot Boss mobile app for handheld devices that are powered by Android. You will need to download the app from the UK Google Play Store, load up the casino and register or log in.

The app lets you access all of the products and services offered on the website. You will find well-organised tabs to take you to your favourite mobile games, claim bonuses, make a deposit or request for a payout, contact support, and more.

Unfortunately, Slot Boss does not currently have an app in the Apple App Store for iOS users. But that shouldn’t be a deal-breaker because the website is fully compatible with all modern mobile browsers.

There are several payment methods available to UK players at the Slot Boss Casino. You can fund your account or take out your winnings using Bank transfer, Maestro, MasterCard, PayPal, Neteller, Visa or paysafecard.
