About this Slot
Super Massive by Spin Slaughter is a space-themed cluster pays slot with six reels, five rows and an RTP of 96.5%. The game features high volatility and a maximum win of 471,588x stake.
Winning clusters of five or more matching symbols touching horizontally or vertically trigger cascades, where symbols disappear and new ones drop to create potential chain wins. A Gravity Multiplier starts at x1 and climbs by one level with each cascade within a single spin, resetting to x1 on the next base game spin.
The Wormhole wild substitutes for winning symbols to complete clusters. During the bonus round Beyond Horizon, the Gravity Multiplier persists across free spins rather than resetting between them.
Four or more Supernova scatter symbols trigger 12 free spins in the Beyond Horizon round. Three or more Supernova scatters landing during free spins retrigger the feature, adding four additional spins; multiple retriggers stack within the same bonus round.
Cat Rescue occurs once per base game spin or free spins feature, randomly pulling Cadet Whiskers into a black hole for a payout ranging from 20x to 250x stake.
Five bonus buy options let players enter the feature directly: DARK MATTER costs 1.25x bet, THREE-WILD SHOT costs 1.7x bet, Event Horizon costs 120x bet, EJECTA REACTOR costs 225x bet, and Singularity costs 400x bet.
