We are all aware of the fact that some iGaming software providers always strive to improve the world of video slots in the best possible way and Relax Gaming is definitely one such provider. 

They’ve introduced Kluster Krystals Megaclusters - and gem-themed online video slot played on a large 5x5 grid with Cluster Pays mechanics. 

In terms of available bonus features, punters can expect Megaclusters, multipliers, Cascading Reels, and Free Spins, while the maximum win stands at solid 9.921x the bet. 

As far as odds are concerned, this online release acts pretty good as well - its RTP is set at 96.49% which is always good to see. 

Finally, it's a fully optimized one-armed bandit and you’ll be able to enjoy it on all devices and across all known platforms. 

Now, let’s see what this is really about, shall we? 

Theme and Symbols 

Kluster Krystals Megaclusters’ design spins around colorful gems placed on a large grid which is set inside something that looks like an ancient portal. 2 large concrete pillars surround the grid itself, while a relaxing soundtrack will definitely make your stay here even better.

Before we jump into the symbols segment, we should mention that the game features Symbol Upgrade mechanic meaning that icons can come in 4 different shapes - single, double, triple, and quadruple and they’re going to be upgraded whenever they're next to a winning cluster. 

The paytable consists of 5 symbols in total (keep in mind that we’re talking about single ones here) - green, blue, purple, pink, and orange gems that can pay up to 50x the bet for a cluster made of 20 icons. 

Even though it doesn’t feature Wild symbols, the title comes with a scatter/bonus symbol that can be upgraded as well. 

Betting Options

Klusters Krystals Megaclusters uses a pretty large 5x5 grid with Cluster Pays mechanics. The winning combinations are formed by connecting at least 8 identical symbols either horizontally or vertically. 

The minimum available bet is set at 0.1 coins while the maximum one can go as high as 100 coins per spin. 

It’s a highly volatile online release with a return to player of 96.49% which is significantly above the current industry’s average. 

At the end, we should also mention the top payout of 9.921x the bet. 

Special Features

First of all, players will benefit from Multiplier symbols. Each icon can come with x1, x2, x3, x4, x5, or even x10 multiplier and they can be upgraded if they’re located next to a winning cluster. Each upgrade will increase the multiplier’s value with a corresponding base multiplier. 

It’s good to see that this online game comes with 3 mini features that can be triggered after 6 successful cascades: 

  • Krystal Vanish - removes one group of symbols from the grid;
  • Krystal Boost - upgrade all present symbols;
  • Krystal Kut - removes all single symbols from the grid; 

If you manage to fully upgrade the Bonus Symbol, you’ll activate the Free Spins feature and the game will award 7 spins free of charge. Also, the round can be re-triggered by fully upgrading another Bonus Symbol during the feature. 

Finally, thanks to the Cascading Reels mechanics, all winning symbols will be removed from the grid, allowing new ones to fall on their places. 


Kluster Krystals Megaclusters is definitely an online video slot that many punters across the globe have been waiting for. Designed by Relax Gaming casino software and packed with extremely unique bonus features, it can pump up to 9.921x the bet while keeping the RTP at a solid 96.49%.
