Kluster Krystals Megaclusters Features

As the name suggests, Kluster Krystals Megaclusters uses the Cluster Pays system but is more enhanced. With Cluster Pays, you match symbols on a grid rather than traditional paylines. Megaclusters brings the possibility of upgrading symbols causing the win potential to soar.

Kluster Krystals Megaclusters also feature 3 random features that are guaranteed to be triggered after a sequence of 6 avalanches. These features include:

Kluster Krystals Megaclusters - Free Spins

Free Spins

Upgrading the bonus symbols fully will activate the free spins round. You win 7 free spins after upgrading and can re-trigger an additional 4 spins if you upgrade a symbol during the free spins round.

Kluster Krystals Megaclusters - Symbol Upgrade

Symbol Upgrade

Base symbols can be upgraded and come in four different forms. Starting with singles, doubles, triples and quadruples - symbols upgrade once they are next to a winning cluster.

Kluster Krystals Megaclusters - Multiplier Feature

Multiplier Feature

Multipliers start at 1x on the reels with the chance of going up to 10x. Not only that, but each multiplier can be upgraded three times. Landing a 10x multiplier could end up being upgraded to a 40x multiplier. Multipliers are upgraded when they are next to a winning cluster.

Kluster Krystals Megaclusters

Fans of Cluster Pays will be ecstatic with Kluster Krystals Megaclusters as it makes winning big even easier. This tiki themed slot plays on 5 rows with 5 columns and no traditional paylines. Instead, you win by matching up symbols on the reels either horizontally or vertically.

Developers Relax Gaming have included free spins, multipliers and other bonus features to ensure that you’ll gain precious ‘krystals’.


As the game begins, you’ll notice relaxing but mythical music that plays. This mixed with the serene vocals of wildlife will instantly calm you. The background image is a tribal altar with the symbols floating between the altar. It feels like some kind of special ritual but definitely adds a whole other dimension to it.

In the distance, you’ll notice a night sky with constellations. It honestly looks really great. Sadly, it’s not animated but the level of detail is impressive. Overall, the full aesthetic of Kluster Krystals Megaclusters is pretty good as it keeps a clean and neat style to it.


As confusing as Cluster Pays and Megaclusters sounds - it’s relatively simple. If anything, it’s easier than traditional slots as you don’t need to learn any paylines. You just have to match up symbols anywhere on the reels and the game will sort the rest out for you.

All menus are situated at the bottom of the screen. Impressively, you can set up to 1000 autospins in this game but of course you can cancel these at any time. The spin and the bet button are next to each other with bets starting at 0.10 and increasing to 100.00.

Win Potential

As Kluster Krystals Megaclusters forgoes the traditional paylines, the possibilities are endless for how you win. With added free spins and other bonus features, the win potential increases even more.

Betting at the maximum 100.00 and winning 20 of the red symbols on a cluster can award you 5000x your stake in the base game. However, it doesn’t stop there. Symbols can upgrade by up to 10x with the multiplier so you could even win 50,000x your stake.

This combined with a great RTP at 96.49% makes it a slot that is worth playing. It does have a high volatility level meaning that returns are less frequent - but will pay out higher when they do.

Our Verdict

Whilst Kluster Krystals Megaclusters doesn’t reinvent the wheel, it’s an exciting slot with some great mechanics. They utilise the traditional Cluster Pays to make something even more enticing for players. Not only do you have unlimited ways to win, but now symbols can upgrade for bigger payouts.

All these factors combine together to make it a slot that is worth your time. Make sure that you are aware of the high volatility level, and you could be set for some great gameplay.
