  • Cashback Weekend. Does what it says on the tin- a chance to earn some cashback.

What games can I play?

Slot King Casino offers both slot games and casino games, including live casino tables and jackpot games.

Some of our favourites are:

  • Diamond Hill. This lovely game is peaceful and calm, with a waterfall and lake background. Diamond gems of various colours make up all of the symbols in this game except wilds. The wilds can appear on reels 1 and 5, and will bring a multiplier and a respin to your win.
  • Rich Wilde and the Book of Dead. Hunt for treasure and dodge the traps in this Egyptian tomb! Three scatter symbols will trigger free spins, and during your free spins, one random symbol can expand for bigger wins. The artwork is great, and the Egyptian theme is fun.
  • The Legend of Shangri-La: Cluster Pays. Group 9 or more symbols together to score a win in this lovely slot themed around a Japanese garden. Koi carp, flowers, and dragonflies all cover the reels, and wise guru symbols contribute 2 symbols towards the cluster of 9, rather than just 1.
  • Playboy Gold Jackpots. The bunnies are glam as ever in this 100-line slot. Four classic playmates count as Jumbo Block symbols, and landing the whole symbol triggers special features like multipliers, a lump prize, or respins. If you only partially land the Jumbo Block, it will transform into bunny symbols of that playmate's respective colour.
