Kluster Krystals Megaclusters Slot Review – Relax Gaming

It has been a while since I last reviewed a Relax Gaming slot release. This last review is titled ‘Frequent Flyer‘, which surprises with unique visual aspects and a max win of over 5,000x. Today we are learning all about the studio’s first release of the year 2021. Which is titled ‘Kluster Krystals Megaclusters’, which is available to play now across all sites.

This game uses the exciting new mechanic from studio Big Time Gaming. A long list of studios now use the Megaways mechanic and now a line of providers ready to use Megaclusters. The slot background is simplistic with a dark night sky in a forest setting. With colourful gems to represent symbols. Overall, I like the unique visual style.

Kluster Krystals Megaclusters has a setup of 5 reels by 5 rows, this includes cluster pays of 8 or more matching symbols. This game is high variance with a set RTP of 96.49% and max win capped at 9,921x. You can bet from £0.10 – £100.
