Crystal Clusters

BGaming software developer launched Crystal Clusters on August 25, 2025, bringing another gem-focused release into its catalog, this time framed around cluster-pays gameplay. Instead of reels and paylines, the action runs on a 7x7 grid that rewards groupings of matching symbols. 

The slot leans heavily into very high volatility, paired with a 96.5% RTP and a top payout of 5,000x the stake (up to 250,000 credits). This makes it a title tailored more toward players willing to take bigger risks in exchange for the chance at sizeable wins.

Theme and Symbols

The setting places players in an underground cavern lit by luminous crystals. The backdrop is intentionally dark and heavy, allowing the glowing gems to pop visually each time they connect. The design isn’t about over-the-top effects; instead, it carries an atmospheric quality that emphasizes the mining-adventure vibe. 

While gem themes are familiar in online slots, the cascading collapses and explosive reactions give this one a more modern edge. Each cluster trigger and collapse creates a sense of movement that keeps the visuals engaging without becoming overwhelming.

Betting Options and Special Features

Gameplay of this online slot unfolds on the 7x7 grid with cluster pays replacing standard paylines. Wins occur when five or more identical symbols connect horizontally or vertically, after which they vanish and make room for new ones to drop in. This creates chains of potential wins during a single spin.

The game carries very high volatility, so spins can run dry for stretches, but when clusters line up with multipliers, payouts can scale quickly. The theoretical RTP is set at 96.5%, which is competitive among grid-style releases. Maximum wins cap at 5,000x the bet (up to 250,000 credits), appealing to those chasing heavier payouts rather than steady small returns.

Crystal Clusters centers its feature set on multipliers and a Free Spins mode:

• Cell Multipliers – Winning clusters leave behind multipliers starting at x2, which double each time another cluster hits the same spot, up to x128. Multipliers apply to all connected clusters and combine if more than one is involved. In the base game, they reset once cascades finish, but during Free Spins, they stay locked until the round ends.
   
• Free Spins – Land 3 to 7 Scatters to trigger between 10 and 30 free spins. Multipliers remain sticky here, making this the round where the biggest wins are most likely to occur. Retriggers are possible if new Scatters appear.
   
• Scatter Symbol – Scatters can appear on all reels, with one per reel, determining how many spins are awarded.
   
• Buy Bonus – For those who don’t want to wait, direct entry into Free Spins can be purchased, with the price tied to the current bet size.
   

These features work together to make the multiplier mechanic the main driver of potential large payouts.

Conclusion

Crystal Clusters takes BGaming’s approach in a darker, more atmospheric direction compared to some of the studio’s lighter titles. The grid-based format, high volatility, and cell multipliers that can climb to x128—especially when sticky in Free Spins—are the main selling points.

For seasoned players, the combination of risk and reward will be appealing, while the straightforward cluster-pays mechanic ensures it remains approachable for newcomers. Overall, it’s a slot best suited for those comfortable with variance and looking for gameplay where big outcomes hinge on building up multipliers over time.
