Zombie Outbreak

Zombie Outbreak Slot Review

Zombie Outbreak slot machine by PG Soft is a 5x4 horror-themed slot game with 1,024 ways to win. The game includes exciting features such as cascading reels, expanding wilds that come with multipliers and a free spin round where the multiplier increases with each win. If you are looking for a game with high volatility and the potential to pay out big (up to 5,000 times your bet) then this could be the game for you.

Theme & Storyline

The Zombie Outbreak game is set in a dark laboratory. Here, a scientist has been conducting forbidden experiments, specifically with zombie serum. Things quickly spiral out of control, as one might expect in this eerie environment: The scientist accidentally turns himself into a zombie and promptly becomes the Wild symbol.

Creepy graphic and scary sound effects create a frightening but captivating atmosphere without being too harsh. If that’s something you enjoy, then you should add games like Zombie Town by Belatra Games to your list.

Slot Layout & Bet Information

Zombie Outbreak game has 5 reels and 4 rows, giving you 1024 ways to win. You can place bets from $0.20 to $100 per spin, which makes it suitable for both low and high-stakes players. The cascading (or "collapsing") reels remove winning symbols and drop in new ones, giving you a chance for more wins in a single spin.

Symbols & Paytable

Here’s a breakdown of the main symbols and their payout values based on 3, 4, or 5 of a kind:

• Mad Scientist (Wild) Substitutes pay symbols and expands on reels 2 & 4 with 3 multipliers
• Toxic Hazard (Scatter) 3+ triggers 15+ free spins, retriggerable

RTP, Volatility & Max Win

With an RTP of 96.76%, Zombie Outbreak slot machine sits comfortably above the industry average. It's a high-volatility slot, so players should expect dry spells between potentially significant wins. The maximum win possible is 5,000x your stake, especially achievable through the free spins round where the global multiplier doesn’t reset. But if you’re looking for even bigger rewards, Zombie Carnival by Pragmatic Play with a max win of 18,000x your bet can suit you more.

Bonus Features Overview

Collapsing Reels

Every win removes the winning symbols and replaces them with new ones. This continues as long as you keep getting wins.

Expanding Multiplier Wilds

The male scientist wild appears on reels 2 and 4, always expanding to fill the reel. It comes with 3 random multipliers (like x1, x2, x3 up to x25).

• Each time you get a win, one of these multipliers is added to a global win multiplier.
• The wild stays in place until all 3 multipliers have been used or no more wins land.

Free Spins

Get 3 or more scatter symbols to unlock 15 free spins (plus 2 extra spins per additional scatter).

• The global win multiplier from the wilds keeps growing and doesn’t reset between spins.
• You can also re-trigger the free spins.

Bonus Buy (not available in the UK)

You can buy direct access to the free spins round for 75x your bet.

Mobile Compatibility & User Experience

As expected from PG Soft, Zombie Outbreak slot machine is designed with mobile players in mind. It performs smoothly on smartphones and tablets with crisp visuals and intuitive controls. The dark, atmospheric graphics and soundtrack translate well to smaller screens, delivering an immersive experience on the go. The fast-paced gameplay is enhanced by a turbo mode, making it perfect for quick sessions or extended play.

However, the game might look weird for desktop users, so it’s worth checking games like Zombie Land by KA Gaming for a more desktop-oriented gameplay.
