Zombie Outbreak

Zombie Outbreak is a high-volatility video slot from PG Soft, built on a 5-reel setup with a unique 4‑5‑4‑5‑4 row structure and 1,600 fixed paylines. The theme plunges players into a post-apocalyptic zombie world, complete with ruined cityscapes, eerie sirens, and desperate survivors.

Key mechanics revolve around Expanding Wilds with multipliers: when a Wild (Mad Scientist) lands on reels 2 or 4, it expands and adds one of three multiplier values (1× to 25×) to a bar below the reels. These bonuses persist through cascades and accumulate, ramping up tension and reward. Three or more Scatter symbols trigger Free Spins (starting at 15), keep collected multipliers active, and allow retriggers with extra spins. The slot has RTP ~96.76% and offers a max win of up to 5,000× your stake
