Slot King Casino Review

Rating: 4.2/5

Rating: 4.2/5

Slot King Casino is new for Summer 2020 on Progress Play with a bonus spins welcome offer and lots of player promotions.

Slot King Casino

Slot King Casino is well served for slot games with many recent releases alongside the usual suspects (Starburst, Book Of Dead, Bonanza, Viking Runecraft, Fishin’ Frenzy, Thuderstruck II, Foxin’ Wins et al) and there’s also some less well known titles from smaller providers such as Nolimit City.  There’s nothing by Playtech, IGT, Yggdrasil, Pragmatic Play or Red Tiger, however.  Progressive jackpots are not really a big thing at Slot King Casino – they are mostly by Eyecon and there’s none of the really big ones.

Rather more unusually there’s a section for V-Sport, which simulates sports betting on football, tennis and various forms of racing including greyhounds – a bit different to say the least!  Bizarrely, the V-Sport section is also where you’ll find Dream Catcher, various scratchcards and instant win games like Epic Gems.

Progress Play casinos always have lots of player promotions, almost all of which are weekly promotions involving making deposits at specific times or in response to personalised emails to collect bonus or spins.  There’s usually also a monthly special and occasionally there’s a leaderboard or prize draw – so there’s certainly plenty to keep players interested.

Slot King Casino is optimised for mobile play and you can even deposit on the go with mobile phone billing (there’s a fee for this though).
