Kluster Krystals Megaclusters Slot (Relax Gaming)

Kluster Krystals Megaclusters Slot (Relax Gaming)Big Time Gaming has been credited for bringing onboard very successful innovations, and these are the Megaways, and the Megaclusters systems.

Relax Gaming has obtained a licence from BTG to use this design on several of their slots, and one of them is Kluster Krystals Megaclusters.

After playing this slot for several days, here is my unbiased review:

Game Set-Up

Kluster Krystals Megaclusters uses a 5x5 reels setup. The game offers the Cluster Pays system that is combined with the Megaclusters mechanic.

For the features, you get to work with Avalanches, multipliers (up to 10xs), free spins, as well as several random modifiers.

Betting and Prizes

The slot uses the usual betting range of between $0.10 per spin and $100 per spin.

The developer has not mentioned any cap on the winnings; however, individual clusters will pay as much as 50x the stake. With the help of multipliers, this can get to 500x.

The Avalanches boosts the game area with the help of the Megacluster mechanic, and this gives the slot lots of potentials.

Kluster Krystals Megaclusters is a highly volatile video game, but it also offers a decent RTP of 96.49%.

Kluster Krystals Megaclusters Slot Features

Since the slot uses the Cluster Pays system, you will be required to form winning clusters.

To do this, Relax Gaming wants you to get between 8 and 20+ symbols next to each other. These must also touch each other either horizontally or vertically.

The Avalanche will come on board and help you trigger additional symbols. These symbols will appear randomly, but only after you get through the 6 successive avalanches.

The modifiers will come in to help either by removing the single symbols, upgrading the symbols coming in the next stage, or even removing entirely a particular type of symbol from within the game area.

To enjoy some free spins, you will need the help of the special Bonus symbol, and clusters must form next to it. This will upgrade it, and at this level, the slot will reward you with 7 free spins that you can also retrigger.

Theme & Design

I find it unusual when it comes to its appearance. From the shape to the stars, circles, and even the squares, it’s a slot machine that looks quite unfamiliar.

The shapes appear in different colours that include red, green, pink, purple, and blue.

It took me a while to realise that this slot uses the Megaclusters mechanism since its design is totally different from what I have seen on slots from Big Time Gaming, which is a good thing.


Kluster Krystals Megaclusters is a very unique slot despite the developer using a popular mechanism.

It is good to see a developer borrow an idea and use it to create something of their own

The payments are good, and so is the RTP. However, as a highly volatile slot game, you need to tackle it with a lot of caution.
