Zombie Invasion

Zombie Invasion by DragonGaming is a video slot built on a 5×3 grid with 30 fixed paylines that plunges you into a post-apocalyptic, zombie-infested city. The theme is rich and cinematic: survivors, decaying streets, biohazard signs and undead alike create tension and atmosphere as you spin. The game offers several special features, including Free Spins, Random Wilds, and a standout bonus round called Escape Infected City. Free Spins are triggered by landing three, four, or five scatter symbols anywhere and award 10, 15, or 20 spins respectively. During the Free Spins round, Random Wilds become more active: smoke bomb Wild symbols can appear and expand wild coverage to help form winning combinations across paylines. The Escape Infected City bonus activates when three expanding Bonus Zombie symbols land on reels 1, 3 and 5 simultaneously; this sends you into a multi-level pick-and-choose style bonus where you progress through five “floors” of a hospital building. On each level you choose doors which either grant you a prize and progression or end the bonus by encountering a zombie, with the big reward for clearing all five levels being a multiplier of up to 1,000× your bet. Regular Wild symbols substitute for standard symbols to complete wins, but do not replace the Bonus or Scatter symbols. Bets cover the full 30 paylines on every spin, and staking ranges allow for both modest and larger wagers.

You can play it for real money.
