About this Slot
Cluster Engine is a Steampunk and money-themed slot from Crimson Clover with an RTP of 96.5%, high volatility, and a maximum win of 100,000x. The game uses five reels and five rows with Cluster Pays mechanics, where matching symbols adjacent horizontally or vertically form winning clusters.
Cascading symbols drop and new symbols fall to fill empty spaces after each cluster win, potentially creating multiple consecutive wins within a single spin. The Loot Meter fills with every cluster formed during play. As the Loot Meter progresses, it unlocks Sticky Wilds and increases a global multiplier that applies to the entire round. Cell multipliers persist across spins and remain active during free spins, growing independently of cascades and maintaining their structure even as symbols cascade and fill gaps.
Sticky Wilds convert treasure types to locked symbols and remain in place through subsequent cascades. The global multiplier grows with Loot Meter progression and applies to all wins generated during the round. A Power symbol is guaranteed on every spin. Free Spins can carry over between individual spins, allowing accumulated free spins to build across multiple plays.
