Crystal Clusters Review: Dig for Gems and Wins for 250,000 Max Win

Matija Antic rated this game:

2.5 out of 5

Crystal Clusters by BGaming transports you into a hidden cavern where you dig for glowing gems and shimmering crystals through traditional reels. Built on a 7×7 grid with cluster-based mechanics, it trades paylines for explosive chains of matching symbols that collapse and make room for new stones.

Crystal Clusters builds its identity around the idea of an underground treasure hunt. The theme is rooted in mining, but it avoids the usual pickaxes-and-helmets imagery and instead focuses on the allure of mystical crystals glowing in the dark. This gives the game a magical rather than industrial feel.

To keep the grid in motion, you’ll find a cycle of wins and respins. The visuals lean dark and immersive, but the bright gems bring the screen to life. Lower-paying greens, reds, and pinks handle the smaller wins, while the more valuable blues and yellows flash, offering bigger potential.

What sets the game apart is the multiplier system; each time a cluster lands, it marks its cells, and in case another win overlaps, multipliers grow from x2 and can climb all the way to x128 your bet. During Free Spins, these multipliers stay sticky, turning the grid into a high-voltage minefield of glowing rewards.

In the base game, my payouts mostly hovered between 1.5x and 5x outcomes, and a few better runs stretched to 7x or 8x my stake, but just 2 or 3 times. The peak of my game came when a cascade linked into multipliers and climbed to about 20x my stake, which felt like the first valuable moment of my session.

Free Spins are where the slot really comes alive, with sticky multipliers ratcheting up the tension. For those who want to skip ahead, a Bonus Buy at 200× the bet gives instant access.

With a generous 97.02% RTP and a top prize of 250,000, I see Crystal Clusters built for players who don’t mind a bumpy ride and are happy to sit through the quieter sessions in search of that one big moment.

PROS

Long gaps between big payouts

Free spins finally paid off

Crystal clusters has a cool theme and the cluster system is fun for a while. Base wins were kinda meh, but I hit 52x during free spins and it made the grind worth it. Not easy to trigger tho unless u buy in.

good rtp but slow burns

I liked the idea of the sticky multipliers, especially in the free spins. I hit a 20x win once and that was the highlight. Solid RTP helps, but most sessions felt slow without bonuses.
