Zombie Outbreak slot accommodates bet ranges from €0.2 to €100 per spin, making it accessible to both casual players and high rollers. The game utilizes a unique 4-5-4-5-4 grid layout with 1,600 ways to win, requiring matching symbols across 3+ consecutive reels from left to right for winning combinations.
Winning calculations multiply the number of matching symbols per reel together, then multiply by the corresponding paytable value. Since the base stake equals 20, divide the total by 20 to determine your win multiplier. Our paytable below shows these calculations converted for easy reference.
Zombie Outbreak slot delivers a collection of familiar features enhanced with innovative expanding multiplier wilds that create an exciting twist, particularly during the bonus round. Explore these thrilling mechanics below!
Winning symbols disappear from the grid, allowing new and existing symbols to fall into empty positions. This mechanic can create unlimited consecutive wins within a single spin, continuing as long as new winning combinations form after each cascade.
The male scientist Wild symbol appears exclusively on reels 2 and 4, always expanding to fill the entire reel. Each wild displays 3 random multiplier values from these tiers:
• x1, x2, and x3 • x2, x3, and x5 • x3, x5, and x12 • x5, x10, and x15 • x10, x15, and x25
A gunshot targets the expanded wild, collecting the lowest multiplier value to boost the global win multiplier. The expanded wilds remain active for subsequent cascades, adding the next lowest multiplier with each new win until all three values are collected or cascades end.
Landing 3+ hazard scatter symbols in view during any cascading sequence triggers the Bonus Round, awarding 15 free spins plus 2 additional spins for each extra triggering scatter beyond the minimum requirement.
The key difference from base gameplay is that the global multiplier from expanding wilds never resets between free spins. This multiplier enhances all wins and continues growing indefinitely whenever new expanding wilds appear. Retriggering occurs with 3+ scatters, granting 15 extra spins plus 2 additional spins per extra retriggering scatter.
Qualified players can purchase direct access to the bonus round through the buy feature menu for 75x your stake. This guarantees 3+ triggering scatters on the following spin to activate free spins immediately.
