Event Horizon

Event Horizon is a space-themed Aztec mythology slot by Sp Games with an RTP of 96.7%, high volatility and a maximum win of 15,000x. The game plays across a 6x6 grid using Cluster Pays mechanics. Winning clusters trigger cascades that continue until no new cluster forms, with two middle columns refilling from a central hole.

Winning cells start with a x2 multiplier that doubles with each subsequent win during the cascade, capped at x128. Multipliers reset on each base game spin. After three cascades complete a Solar Cycle, three wild symbols are awarded around the hole; the Solar Cycle count then resets.

The Charged Board feature randomly pre-loads four to eight cells with multipliers of x2, x4 or x8, though bonus symbols are never charged. Solar Flare randomly fills the ring with three to five wilds and prevents the hole from swallowing symbols. Gravity Beam converts an entire outer line to wilds, hitting either rows or columns 1, 2, 5 or 6. Gravity Lens converts one low-pay symbol type upward when at least three are present, triggering once per spin maximum and preventing symbol swallowing.

Singularity triggers with four bonus symbols, awarding six free spins. The hole swallows one to three charged symbols and spits wilds per cascade. Gravity Storm requires five bonus symbols, awarding eight free spins with all twelve ring cells charged. Charged cells double per cascade, the hole does not swallow symbols, and clusters are capped at x32. Eclipse requires six bonus symbols, awarding ten free spins where the hole spits one wild per spin and a global multiplier increases by one per cascade, with clusters capped at x32.

Buy options are available at Singularity (100x bet), Gravity Storm (150x bet) and Eclipse (250x bet).
