Kluster Krystals Megaclusters Overview
Kluster Krystals Megaclusters is a sparkling gem slot from Relax Gaming. It was Relax’s first game to use Megaclusters, a mechanic created by Big Time Gaming. Relax launched it in January 2021, calling it the game to kick off its year.
In Megaclusters games, symbols don’t just win and vanish. Symbols next to a winning cluster upgrade into double, triple or quad versions. That means one win can turn the grid into a much busier, richer board.
There’s plenty more going on. You’ll find avalanches, growing multipliers, three random Krystal features and a free spins round. Our original review rated it as high volatility, with an RTP of 96.49%.

Theme and Design
The grid is filled with shiny, faceted crystals in bright colours. Orange, pink, purple, blue and green gems glitter as they land. It has a clean, modern look that suits the busy mechanic.
The symbols come in four sizes: single, double, triple and quad. As they upgrade, the board fills with smaller and smaller gems. Watching a big upgrade chain unfold is a big part of the fun.
How Megaclusters Works
In Kluster Krystals, you win by landing clusters of matching symbols. When a cluster wins, the symbols next to it get an upgrade.
A single symbol can become a double, then a triple, then a quad. Each upgrade splits the symbol into smaller pieces. More pieces on the grid means more chances to build bigger clusters.
After every win, the winning symbols are removed. New symbols then drop in from above. Relax calls this an avalanche. It keeps going until no new clusters form.
Relax’s Chief Product Officer, Simon Hammon, praised the game’s fast-paced features and maths model at launch. He also called Megaclusters a headline-grabbing mechanic from Big Time Gaming.
Betting, RTP and Volatility
Our original review listed bets from $0.10 up to $100 per spin. It gave an RTP of 96.49%, which is a touch above the online average.
The game was rated as high volatility. Wins can be spread out, but the upgrades and multipliers can build big results.
Kluster Krystals Symbols
Our original review listed these symbols:
- Orange, pink, purple, blue and green crystals: the higher-paying symbols, worth 20x to 50x your stake for clusters of 20.
- Lower-paying gems: smaller crystals that land more often.
- Bonus symbol: a gold crystal marked with the word Bonus.
Each symbol can appear as a single, double, triple or quad. The bonus symbol also upgrades when it sits next to a winning cluster.
Kluster Krystals Bonus Features
Here’s a quick summary of the features:
- Symbol upgrades: symbols next to wins split into doubles, triples and quads.
- Avalanches: winning symbols are removed and replaced.
- Multipliers: multipliers can upgrade up to three times their starting value.
- Krystal mini features: three random features linked to six avalanches.
- Free spins: up to 7 free spins, with the chance of 4 more.
Multipliers
Multipliers can land next to a winning cluster. Our original review said they start at 1x, 2x, 3x, 4x, 5x or 10x. Relax confirmed at launch that they can upgrade up to three times their starting value.
When the avalanche sequence ends, the multipliers are added together. The total is then applied to your win.
Krystal Mini Features
Kluster Krystals has three random mini features. Relax’s launch announcement linked them to sequences of six avalanches. Our original review described them like this:
| Feature | What it does (original review) |
|---|---|
| Krystal Vanish | Picks one symbol group and removes it from the grid |
| Krystal Boost | Upgrades all regular symbols by one stage |
| Krystal Kut | Removes all visible single-stage symbols |
Each one clears or upgrades the board, which can set up a fresh run of wins.
Free Spins
The bonus symbol starts the free spins. It upgrades each time it sits next to a winning cluster. Once it reaches its full four-segment form, you win 7 free spins.
During the free spins, landing another bonus symbol adds 4 more spins. Relax’s launch announcement confirmed the round awards up to seven free spins, with the potential to unlock four more.
How to Play Kluster Krystals
- Check the help screen: confirm the RTP and bet range at your casino.
- Set your stake: high volatility needs a sensible budget.
- Spin the grid: clusters win and upgrade the symbols around them.
- Watch the avalanches: each one can bring new wins.
- Upgrade the bonus symbol: a full upgrade starts 7 free spins.
Who Is Kluster Krystals Best For?
Kluster Krystals suits players who enjoy busy, modern mechanics. The upgrades and avalanches give every spin a chance to snowball.
It’s a good fit if you:
- Like cluster games: wins come from groups, not paylines.
- Enjoy chain reactions: one win can lead to many more.
- Accept high volatility: the big results take patience.
If you prefer simple slots with a clear paytable, it may feel a little busy.
Tips for Playing Kluster Krystals
- Try the demo first: the upgrades make more sense once you’ve seen them.
- Watch the bonus symbol: it needs four upgrades to start the free spins.
- Enjoy the Krystal features: they can clear the board for new wins.
- Set a budget: high volatility means big swings either way.

Why Symbol Upgrades Matter
Symbol upgrades are what make Megaclusters games so different. A normal cluster slot removes winning symbols and drops new ones in. Kluster Krystals also upgrades the symbols around each win.
Smaller symbols take up less space, so more of them fit on the grid. That gives you more chances to build big clusters on the next avalanche. A single good spin can snowball into several wins.
