Set deep beneath the Earth’s surface, Crystal Clusters invites players into a hidden world of luminous stones and glittering treasures.

Classic Multihand Blackjack How to Play

• Crystal Clusters is played on a 7×7 grid using a cluster pays system. Wins are formed by landing groups of matching symbols, which then collapse and trigger cascading drops. Each symbol drop marks the grid, increasing the multiplier for that cell from x2 up to x128. These multipliers apply to future wins and become sticky during Free Spins, amplifying payout potential. Scatters unlock the Bonus round, which can be retriggered, and a Buy Bonus option allows players to jump straight into the feature. The game is designed for very high volatility, with chain reactions and grid-based multipliers driving the core gameplay.
