4 Horsemen

The 4 Horsemen slot by Spinomenal features a 5x3 grid with 25 paylines in a post-apocalyptic setting of scorched ruins and blazing skies, accompanied by dramatic audio. Gameplay centers on the biohazard Wild symbol, which pays only when three or four land adjacent to Bonus or Free Spins symbols on reels 1, 3, and 5; three Free Spins symbols award 3 free spins and 3x the bet. During free spins, symbols on reels 2-4 can expand to 3x3 Colossus symbols, with Free Spins Colossus granting 3 extra spins and 3x bet payout, while Scatter Bonus symbols trigger the Hold & Hit bonus. In Hold & Hit, six or more bonus symbols lock, starting with 3 respins that reset on new symbols, offering multipliers up to 10x, Mini (25x), Major (50x), Mega (250x), and Grand Jackpot (5000x) for filling all 15 positions. This combination of expanding Colossus symbols and progressive Hold & Hit jackpot collection distinguishes it within Spinomenal's mythology series, blending medium volatility with high win potential up to 8250x.
