Kluster Krystals Megaclusters
Kluster Krystals Megaclusters Free Slot Demo Review
Kluster Krystals Megaclusters is Relax Gaming’s first Megaclusters slot. It has a crystal theme where symbols split and upgrade on every spin, and it was released on January 12, 2021. You can try it right away with the free demo, no sign-up needed.
How is the Megaclusters mechanic different from regular clusters?
When a winning cluster forms, the surrounding symbols upgrade into 2-way, 3-way, or 4-way split symbols. One cell splits into several, so the next win follows more easily. As the first Megaclusters title among Relax Gaming slots, it’s a good pick if you want a taste of the original version of this mechanic. When you try later Megaclusters games, learning the structure here first makes them much easier to understand.
Do multipliers get upgraded too?
Yes, the upgrade effect applies to multipliers too. A multiplier can rise to up to 3x its starting value. When a multiplier symbol sits next to a winning cluster, the win size jumps significantly. If an upgraded multiplier is part of a big cluster, the result changes a lot, so keep an eye on where the multiplier symbols are. Even a small multiplier becomes a size you can’t ignore once it goes through upgrades.
When do the three Crystal mini features trigger?
If avalanches continue 6 times in a row, a mini feature is guaranteed. Crystal Vanish removes one group of symbols by color, Crystal Boost upgrades all visible regular symbols, and Crystal Cut removes every single-cell regular symbol on screen. Depending on which feature triggers, the way the screen gets cleared is completely different, so anticipation builds with every avalanche in a row.
How do I get into free spins?
When a bonus symbol next to a winning cluster upgrades into a 4-way split symbol, 7 free spins begin. If another 4-way split bonus symbol lands during free spins, 4 spins are added to the 7. Bonus buy isn’t available, so you have to trigger this yourself. Retriggers keep extending the spin count, so focus whenever you see a 4-way split bonus symbol. Watching for bonus symbols that land next to winning clusters in the base game helps you understand the entry conditions quickly.
What should I check first in the demo?
is 96.49% and volatility is very high (5/5). Hit frequency is on the low side at 21.39%, and the max win is 9,921x. Try the demo with a bet range of €0.10 – €100 and start by checking how often avalanches reach 6 in a row. Since bonus buy isn’t available, it’s important to get comfortable with the base game flow.
Pros
- Megaclusters upgrades where symbols split
- A guaranteed mini feature after 6 consecutive avalanches
