Joker Gems Slot

Immerse yourself in the timeless landscape of space in Joker Gems slot from ELK Studios. Like falling asteroids in the nebula, the gems in this casino slot light up the 5x5 reels grid. Instead of paylines, the slot uses cluster mechanics to deliver engaging gameplay and has an above average RTP of 96.30%.

There are quite a number of slots that use cluster mechanics, but not many with three lucrative jackpots like Joker Gems. Instead of free spins, players can trigger re-spins every single time a new winning combination is formed.

Joker Gems symbols

  • Red, blue, orange and green gems represent the low-value symbols
  • Lucky 7 and bar are the high-value symbols
  • The joker is the highest paying symbol

Joker Gems bonus, free spins & jackpot

Instead of having a free spins feature, Joker Gems slot has a re-spins feature that is extremely rewarding. Every single time you form a cluster of at least three matching symbols, the reels are re-spun to give you a chance to form even more winning combos. New symbols may join the initial cluster to form even bigger clusters for bigger wins, or new clusters may be formed. The re-spins will continue as long as new matching symbols are added to the original cluster or new clusters are formed. This feature edges you closer to one or all of the three jackpots featured in Joker Gems.

This slot also has a randomly triggered bonus feature during the base game dubbed the Light Chaser Feature. A light streak will travel across the reels and awards a cluster of 4 to 5 identical symbols which will, of course, be followed by a re-spin. Joker Gems also gives players the chance to win one, or even all, jackpots that can be triggered by landing the predefined cluster patterns. Each pattern awards a fixed jackpot of £10,000, £20,000 or £50,000. The jackpots are awarded independently of the active stake and players have the chance of winning themselves up to £120,000!
