How to play

Kluster Krystals Megaclusters can appear quite complicated to play when players first load the game but once it gets started, it becomes easier to understand. Below the reels, players will spot the + and – buttons that are used to set your bet per line. This is a game for players of all budgets as bets per spin start from as little as 10p and rises to £100.

There are two ways to speed up your gameplay. The first is the autoplay feature which allows you to set your bet per spin and the number of spins you want, then the game will play automatically. The second option is the Turbo feature which speeds up the game spinning. Hit the play button to send the game spinning.

The symbols on the reels of this game are:

  • Green Krystal
  • Blue Krystal
  • Purple Krystal
  • Pink Krystal
  • Red Krystal


The highest value symbol in Kluster Krystals Megaclusters is the orange crystal and this will award 50x your stake when 20 land on the grid.

Special Features

Kluster Krystals Megaclusters is jam-packed with fantastic bonus features and there are seven in total. This includes a tumble feature, multipliers, symbol upgrades, free spins and random mini-features of which three can be awarded.

Tumbling reels are a fan-favourite feature and so many will be pleased to see them in this slot game. When you get a winning combo, the symbols in that combo will be removed from the reels as part of this feature. They’ll then be replaced with new symbols which can lead to more chances of getting a winning combo and being awarded cash prizes. This round only ends when there are no new wins.

A cool feature in this slot game is the symbol upgrades. Players will notice on the reels that the crystals are split up into four different parts. This can appear on your reels as a whole four-part symbol, as three parts of a symbol, as two parts of a symbol or as one part of a symbol. When there is a winning combo formed, all symbols next to it will trigger the symbol upgrades feature and have one piece of the symbol added to it.

There are lots of big multipliers up for grabs in this game and players will want to watch out for the wild multipliers of up to 10x!

The bonus symbol is important in this slot game as when all four crystal pieces are formed within the symbol, it will activate the free spins where players are awarded seven free spins. Retriggers are available and will award four free spins. There is no limit on the number of free spins players can be awarded in this round.

Kluster Krystals Megaclusters offers random mini-features too and these can be triggered when six tumbling reels occur in succession. Players will be awarded one of the three features.

  • Krystal Vanish – One colour group of symbols will be removed
  • Krystal Kut – Any symbols with just one part will be taken from the game
  • Krystal Boost – All symbols on the reels will be upgraded by one part

Graphics and Sounds

There are many slot games on the market with a crystal, out of this world, theme and so this game may seem familiar to some players. While the theme is lacking in its uniqueness, the graphics are still exceptional quality and players will like the backdrop of the reels which is a dark sky filled with stars and the aurora borealis. Each of the symbols in this game is a crystal of a different shape and colour including red, blue, pink, green and purple. Mystical music plays as you spin the reels, which compliments the game nicely.


Kluster Krystals Megaclusters is a great slot game from Relax Gaming and if you are the type of player who enjoys popular online slots such as Starburst, then this could be a great option. While the theme isn’t very special, the graphics are sharp and immersive. This is also a slot game bursting with bonus features and players won’t be disappointed by the range available including the tumbling reels, free spins and big multipliers. This is a game that offers something a little bit different with its 5×5 grid structure and so it’s worth giving a spin for those who are tired of the standard payline structure.
