The flexible bet range of Crystal Clusters makes it accessible to a wide audience. True, it’s not going to be the game for high rollers, as neither the wins nor the bets speak ‘high roller’.  Payouts vary depending on symbol color, with high-value gems awarding up to 150x your bet for clusters of 15+ symbols.

The biggest wins come from combining large clusters with escalating multipliers, particularly during Free Spins where the multiplier marks don’t reset. Thanks to this mechanic, the game’s maximum potential payout can hit a cool 5,000x your stake.

Crystal Clusters shines brightest through its bonus features, which add depth and excitement to the base gameplay. Here are all the features accessible in Crystal Clusters.

Clusters and Cascades

The game has cluster pays, which means clusters are the only way to score a win in the game. Match 5+ gems to form a cluster and trigger a cascade. Within a cascade, all the winning symbols disappear from the grid, new ones drop to the reels, which then means that more wins may form in a single spin. This is a perfect way to trigger bigger wins in the game.

Multipliers

Every time a cluster hits on the grid, its position is marked on the reels. All icons that formed the cluster will be highlighted, and they will also get assigned a multiplier starting at 2x. Each consecutive win on that cell doubles the multiplier, up to 128x, leading to explosive payouts. The 128x multiplier is the maximum multiplier value.

Free Spins

The game’s main feature. Land 3–7 scatters to win 10–30 free spins. During this bonus round, multipliers remain locked between spins, compounding over time and significantly boosting potential payouts. Retriggering the bonus feature is possible by landing additional scatters during free spins.

Bonus Buy

For 100x your bet, you can skip straight to the Free Spins feature. It’s a great option for players who want instant access to the game’s most lucrative mode. However, the option is not available in every market, so please check whether this is accessible in your jurisdiction.

Crystal Clusters performs flawlessly on mobile, with its clean grid design and vibrant gems standing out beautifully on smaller screens. The cascading animations and multiplier highlights are smooth and visually satisfying, making it an excellent choice for portable play.

You can play both on apps and browsers. Browsers are far easier to handle than apps as they require no downloads – just access the game on your Safari or Chrome, and that’s it. With apps, you first have to download them and register and then play.

Theme, Visuals & Sound

BGaming has crafted a visually immersive gem-mining environment with a dark wooden mine shaft setting that makes the bright, glowing crystals pop on screen.

The visuals are crisp and focused, like you would expect from BGaming. Al the attention is being kept on the grid and the action. Subtle ambient sounds give the sense of working deep underground, while wind chimes and feature triggers add excitement to each spin as you play the spins. Those who like the theme will surely like the game, although it’ nothing special.

Our Experience Playing Crystal Clusters

Playing Crystal Clusters was a tense but rewarding experience. The cascading wins create natural excitement, but the true magic happens when multipliers start stacking right in front of your eyes.

One thing that we can definitely confirm is the variance. The volatility is definitely high, meaning there were several winless spins in a row, but when the game hits, it hits big. Or rather, bigger than most slots with such limited winning limits.

The Bonus Buy proved useful for jumping straight to the high-energy part of the gameplay. Only, we are not advising everyone to try it as it costs a pretty penny.
