Slot Boss Casino Bonus Code

Casino - 100% up to £150 bonus + 50 bonus spins
18+. New player only. 7 days to claim offer, min of £10. Wagering req. 35x. 50 wager-free spins 0.10p each on Book of Dead awarded after wagering complete, winnings paid as cash. Full T&Cs apply.

Slot Boss Casino Bonuses and Promotions

New players who sign up to Slot Boss will receive a great casino bonus which commonly includes a match deposit bonus and free spins. Simply sign up and make your first deposit. Your match bonus will be credited instantly, along with your free spins after the match bonus has been played through. There's no need for a promo code.

As with all casinos’ welcome bonuses, there are some bonus terms and conditions to be aware of. The main one here is the 35x wagering requirement. This must be done before any bonus funds become available for withdrawal. These requirements must be met within seven days of claiming the welcome offer or the bonus will expire. The free spins are wager-free, which is excellent, so any winnings from these free spins are paid as cash.

The bonuses don't stop there with Slot Boss though. Weekly offers are common here, every Sunday for example, there's a deposit match offer for existing customers. This online casino also runs a Game of the Week slot promotion, with free spins available on the hottest new release that week.

All ongoing promotions are found in the promotions section on site. We also recommend opting in to marketing emails and SMS messages so you receive the latest offers straight to your inbox.

Slot Boss Live Casino Bonus

Live casino players will be pleased to know that the casino welcome bonus outlined above can be used on live dealer games. The exact same terms apply and the only additional thing to note is that 30% of live dealer game wagers will contribute towards the wagering requirement. 

This is great to see, as many online casinos’ welcome bonus offers cannot be used on live dealer games. It's a nice benefit to have at Slot Boss.

Slot Boss Sports Bonus

You won't find any sports betting odds at Slot Boss, nor indeed a Slot Boss sports bonus. This site is entirely based on casino games.

Slot Boss Bingo Bonus

Slot Boss does not have a bingo product at present. Instead, it focuses on slots, table games and live dealer games.

Slot Boss VIP Programme

Slot Boss does have a VIP programme, but it is available only by special invite. As such, there are no specific details listed on site regarding the programme. 
Everything at Slot Boss is top notch, so we expect nothing else from the VIP programme. VIPs should expect exclusive casino bonuses and cash back offers and fantastic perks like a dedicated account manager, higher deposit and withdrawal limits as well as invites to special events.

Table Games

The range of table games on offer at Slot Boss leaves a little to be desired, with just 13 available at the time of review. What it lacks in quantity, it makes up for in quality though.

Roulette fans will be pleased with the options here, including European Roulette and 20p Roulette, two of the most popular table games at any online casino. Evolution Gaming also provides a First Person Roulette game, which offers players something different. 
For online blackjackk fans, there’s a 6 in 1 Blackjack game from Felt which is something you won't find at many other casino sites and is well worth checking out. Golden Rock Studios and Microgaming also provide varieties of Blackjack at Slot Boss.

Perhaps it will look to add more table games further down the line. A few video poker options would be a great addition to its offering.


With over 600 online slot machines to choose from, Slot Boss has all its bases covered when it comes to variety. It carries games from some of the best software providers around, names like NetEnt, Play'n GO, Pragmatic Play, Microgaming, ELK Studios, Yggdrasil, Blueprint Gaming and IGT all call Slot Boss home. There are also games from perhaps less well known studios too, like Reel Play, Plank Gaming and Kalamba Games to name just a few. You will definitely find your favourite slot game within the aforementioned providers.
For those who prefer playing for big prizes, head on over to the jackpots tab. There are dozens of games from the Jackpot Drop and Jackpot King series at Slot Boss.

Live Dealer Games

Slot Boss live casino is packed with games from Evolution Gaming and Pragmatic Play – two of the best live dealer game software providers you'll find anywhere.
There's an excellent variety of live blackjack, roulette, game show, poker, baccarat and dice games to choose from.

The highlight for us though was the exclusive games at Slot Boss. They're made by Evolution, so you can be sure they're of the best quality, and being exclusive, you won't find them anywhere else.

Slot Boss Review In Summary

The first thing we noticed about the Slot Boss site was the streamlined registration process. There is no right or wrong way to lay out the information which needs to be provided by a new player – some online casinos have a small number of fields per page and multiple pages. At Slot Boss, it's all on one page and takes just a minute to fill in and get your account set up, so you'll be playing in no time.

Once you've signed up, you can make your first deposit using Visa, Mastercard, Paypal or bank transfer. For standard security reasons, the method you use to deposit must be the one used to withdraw. The minimum deposit and minimum withdrawal amount is just £10, so it should suit all bankrolls. Some more payment options would be beneficial and could be something the casino looks to add at some point.

The mobile app deserves a special call out. Most new online casinos are mobile optimised, but not every casino has a mobile app. iOS and Android users can download the Slot Boss casino app from the relevant app store and enjoy everything the casino has to offer while on the go. 

Slot Boss' casino lobby is laid out in a very user friendly way. Games are divided into five categories – live casino, jackpots, table games, instant win and slots. A search bar allows players to look up a particular game or software provider. This layout and user experience is the same on desktop and mobile, but nothing really compares to the speed and each of access with the app.

Some additional filtering options would make finding a game or browsing the lobby a little easier, but as it is, it's a layout which will be familiar to experienced casino players and easy to get around for new players.
