Kluster Krystals Megaclusters is brought to you by Relax Gaming, the first developer in line to make use of the Megaclusters mechanic created by Big Time Gaming. We suspect several other game developers will follow in the future, seeing how popular the Megaways mechanic became. Relax Gaming has gone for quite a different approach to what Big Time Gaming did with this mechanic and the first thing we thought of when seeing the design, was Tetris. Whether it is intentional or not, there is a definitive nod to the classic game from the 80's here, complete with some northern lights giving it a little mystery.

While the slot has drawn it's inspiration from an 80's arcade game, there is nothing classic about the gameplay here. In fact, there is a total of 7 special features going on, making sure there is enough action throughout the slot. These include 3 random mini features as well as a free spins feature with unlimited re-triggers. Not to mention the tumble feature, symbol upgrade and multiplier feature in there too!

How to win big in Kluster Krystals Megaclusters – Free Spins feature

The key to getting the maximum win from the slot is the free spins feature. Trigger it by upgrading the bonus symbol fully, which happens once the bonus symbol is next to a winning cluster. You will then start out with 7 free spins and you will be able to upgrade a bonus symbol in the feature. When this happens, you will re-trigger the entire feature and you will receive an extra 4 free spins. What really makes this feature is the fact that there is no limit to how many free spins you can play with. During the base game, you will be able to benefit from multipliers up to 10, tumbles, the 3 mini features and even symbol upgrades.

Special Features

  • Tumble feature
  • Symbol Upgrade feature
  • Multiplier feature
  • Mini features

Starting from the top, the Tumble feature will apply every time you form a winning cluster. Symbols part of the winning cluster will explode and remaining symbols drop into the empty spaces. In other words, this works the same way as an avalanche feature.

All the symbols in the game come in four different forms as they can appear as singles, doubles, triples or quadruples. Symbols next to a winning cluster will trigger the symbol upgrade feature cause symbols to upgrade to the next size. The slot also has wild multipliers which land with x1, x2, x3, x4, x5 or x10 as their multiplier. When these multipliers appear next to winning clusters, they will also be upgraded just like the standard symbols. The difference here is that with each upgrade, the multiplier will also increase with an equal amount to the symbols original multiplier, this can happen 3 times on each multiplier.

Finally,, we have the mini-features, which are random. They will be guaranteed to be triggered once you have had 6 avalanches in a row. The Krystal Kut feature will remove visible single standard symbols, the Krystal Boost feature upgrades all visible standard symbols by 1 and the Krystal Vanish feature will have to remove all symbols of a chosen colour from the reels.

Look and Feel of Kluster Krystals Megaclusters

While some players (including us) might find it fun that the slot has been inspired by the classic arcade game of Tetris, there really isn't much else going for it. The overall design of the game is pretty boring, plain and simple. We would have hoped that Relax Gaming would have gone all out with the design of their very first Megaclusters slot, but we were wrong. Behind the tetris looking setup, you will see a night sky lit up with some northern lights while the reels have been placed within a couple of stone pillars.

There aren't all that many symbols in this slot, which kind of adds to our statement of it having a pretty boring design. There is a total of 5 differently coloured krystals, a green, purple, blue, pink and orange one with the orange being of highest value.
