Moon Clusters

About this Slot

Moon Clusters is a space and sci-fi themed slot from Scatterbrain Games with an RTP of 95.05%, high volatility and a maximum win of 15,000x. The game uses a 6x4 grid with cluster pays mechanics, where connected symbols create wins and cascading reels keep combinations flowing. Wild Symbols in Moon Clusters start at 2x multiplier when they land naturally. When a Wild wins as part of a cluster, its multiplier increases by 1. Wilds become sticky after winning and can merge with other Wilds to form stronger new Wilds across cascades. Charge symbols do not form clusters themselves. Once all cascades end, every Charge symbol on the board fires and converts four random empty cells into 1x Wilds before disappearing. These newly created Wilds retain the ability to upgrade, stick and merge during subsequent cascades. Golden Charge symbols work similarly to Charge symbols, but each of the four Wilds they spawn lands with a random multiplier between 4x and 100x. Golden Charge appears in specific purchase modes and provides an immediate high-value boost before cluster play continues. Landing three Bonus symbols triggers Bonus free spins. Four Bonus symbols unlock a stronger variant, and five unlock an even stronger variant. During free spins, three or more Bonus symbols retrigger additional spins and allow sticky Wilds to build momentum throughout the feature. Bonus buy options are available at the following bet multipliers: Ante at 1.5x bet, Super Ante at 3x bet, Golden Charge at 150x bet, Bonus at 150x bet, Super Bonus at 400x bet and Mystery Bonus at 500x bet.
