Zombie Outbreak Rules And Gameplay
You can play with bet levels between €0.2 to €100 per spin in Zombie Outbreak slot, which is a bet range that caters to most types of players. The game plays out on a 4-5-4-5-4 grid with 1,600 betways, and you win by landing matching symbols on 3+ adjacent reels starting from the left. The winning symbols per reel are multiplied together, and the sum is then multiplied by the relevant paytable value. Since the base bet is 20, you need to divide the winning sum by 20 to find out how much you win times your stake. We’ve already done this for you in the paytable below.

Zombie Outbreak Bonuses And Special Features
You get a set of familiar features in Zombie Outbreak slot, but the expanding multiplier wilds come with an innovative twist that’s further enhanced in the bonus round. Let’s dive in!
Collapsing Reels
Winning symbols are removed from the grid, making room for new and existing symbols to drop down to fill the gaps. This can lead to indefinite extra wins per round, as the process repeats as long as you keep winning.
Expanding Multiplier Wilds
The male scientist Wild symbol appears on reels 2 and 4 only, and this symbol always expands to cover the full reel. It comes with a set of 3 random wild multiplier values as follows:
- x1, x2, and x3
- x2, x3, and x5
- x3, x5, and х12
- x5, ×10, and x15
- x10, x15, and x25
A gun fires at the expanded wild, and this collects the lowest multiplier value below the grid. The total multiplier will then boost your win, and the expanded wild (or wilds) remain in play for the next cascade of symbols.
If you win again, the second lowest multiplier is added to the total win multiplier to once again boost your win. The same happens if you win a third time. The wilds remain in play for as long as the collapsing reels sequence lasts, or until all 3 multiplier values have been added to the global win multiplier.
Zombie Outbreak Free Spins
You need 3+ hazard symbol scatters in view in the same cascading sequence to trigger the Bonus Round, or they can appear on the very same spin. Either way, you get 15 free spins, with +2 additional free spins added on top of that per additional triggering scatter above the minimum of 3.
The big difference from the base game is that the global multiplier building from the expanding wilds doesn’t reset between free spins. It will boost all your wins and keep growing indefinitely as long as you land new expanding wilds. You can retrigger the bonus round by landing 3+ scatters, which award 15 extra spins plus 2 additional spins per additional retriggering scatter.
Zombie Outbreak Bonus Buy (not UK)
Eligible players can purchase the bonus round via the bonus buy menu, and the price is 75x your stake. This awards 3+ triggering scatters on the spin that follows.
Review Summary And Verdict
Zombie Outbreak is a thrilling horror slot that masterfully blends engaging gameplay with a captivating narrative. The action is punctuated by dynamic visuals and lively commentary, particularly when the female scientist fires her gun at the expanded wild scientist zombie that’s chasing her. The fast-paced spins, amplified by the turbo mode, synchronize perfectly with the dramatic soundtrack in the bonus round, which is a pulse-raiser you don’t wanna miss.
The feature takes things to the next level, as the global win multiplier keeps building towards unknown heights from the expanding wilds without ever resetting. Zombie Outbreak's unique win story adds another layer of intrigue, revealing the female scientist's escape into a zombie-infested world akin to the popular HBO series ‘The Last Of Us’. Overall, this is a must-try game for horror fans and slot enthusiasts alike, promising an adrenaline-fueled adventure that can land you up to 5,000x your stake.
