Crystal Clusters – Online Slot by BGaming

Released on August 25, 2025, BGaming’s online slot Crystal Clusters brings a gem-themed experience built on a cluster-pays format rather than traditional paylines. 

The game runs on a 7×7 setup and combines a very high volatility profile with a 96.5% RTP. With a maximum win potential of 5,000x the stake (up to 250,000 credits), it’s a slot aimed at players who don’t mind taking risks in pursuit of larger rewards.

Dark Gem-Style Visuals

Crystal Clusters places the action inside a shadowy underground cavern, where glowing gemstones take center stage against the dark backdrop. The overall presentation is less about flashy effects and more about creating a strong, moody atmosphere that highlights the luminous crystals. 

While gem-based slots are a familiar sight, the cascading reactions from cluster wins keep the screen active and add a modern flow to the classic theme.

A Grid Full of Possibilities

The slot is built on a 7×7 grid with cluster pays replacing paylines. Wins are formed when five or more matching symbols connect horizontally or vertically, disappearing and making way for new symbols to drop into place. This chain reaction format means that multiple wins can occur within the same spin.

With very high volatility, players should expect dry spells between hits, but payouts can grow rapidly when multipliers come into play. The 96.5% RTP keeps the math model in line with other grid-style releases. At its peak, the game can deliver payouts of up to 5,000x the bet, capped at 250,000 credits.

The game’s mechanics revolve around multipliers and a dedicated Free Spins mode:

• Cell Multipliers – Whenever a cluster win lands, it leaves behind a multiplier that starts at x2. Each additional win in that same position doubles the value, climbing as high as x128. In the base game, these reset after cascades end, but during Free Spins, they remain active until the feature is complete.
• Free Spins – Triggered by landing 3 to 7 Scatters, this feature awards between 10 and 30 spins. The sticky nature of multipliers here makes this round the primary opportunity for the game’s top payouts. Extra Scatters can retrigger more spins.
• Scatter Symbol – Appears across all reels, with the number of symbols collected determining the number of free spins awarded.
• Bonus Buy – For those who prefer skipping the base game grind, the Free Spins feature can be purchased directly, with the cost scaling to the active bet size.

Together, these features ensure that multipliers are at the heart of Crystal Clusters’ potential, particularly when carried through the Free Spins round.

A Perfect Combination 

Crystal Clusters represents a darker, moodier release from BGaming, contrasting with some of the developer’s brighter, more colorful slots. The 7×7 grid, cluster-pays engine, and multipliers that can lock in during Free Spins are its biggest draws. 

With very high volatility and a 5,000x win ceiling, this game is better suited for players who enjoy variance and are comfortable chasing less frequent but larger wins. Compared to other titles by BGaming casino software, it leans more into atmosphere and high-risk gameplay, making it a solid choice for those seeking grid-style slots with strong multiplier mechanics.
