Zombie Outbreak slot accommodates bet levels from €0.2 to €100 per spin, providing flexibility for various bankroll sizes. The game features a 4-5-4-5-4 grid layout with 1,600 betways, where victories occur by landing matching symbols on 3+ consecutive reels beginning from the leftmost position. Winning symbol counts per reel multiply together, then get multiplied by the corresponding paytable value. Since the base bet equals 20, divide your winning total by 20 to determine your stake multiplier. Our paytable below already shows these calculations for your convenience.
Zombie Outbreak slot combines familiar slot features with innovative expanding multiplier wilds that receive exciting enhancements during the bonus round. Here's how these thrilling mechanics work:
Winning symbols disappear from the grid, allowing new and remaining symbols to drop down and fill empty positions. This mechanism can create unlimited consecutive wins per round, continuing as long as new winning combinations form on the reels.
The male scientist Wild symbol lands exclusively on reels 2 and 4, always expanding to cover the entire reel. Each wild displays 3 random multiplier values:
• 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 beneath the grid. This total multiplier enhances your win, while the expanded wild(s) remain active for subsequent cascades. Additional wins add the second-lowest multiplier to the global win multiplier, repeating for a third win if achieved. Wild symbols persist throughout the entire cascading sequence or until all 3 multiplier values join the global win multiplier.
Landing 3+ hazard scatter symbols in view during the same cascading sequence triggers the Bonus Round. You receive 15 free spins, plus 2 additional free spins for each extra triggering scatter beyond the minimum requirement.
The crucial difference from base game: the global multiplier from expanding wilds never resets between free spins. It boosts all wins and continues growing indefinitely whenever new expanding wilds appear. Retrigger the bonus by landing 3+ scatters, awarding 15 extra spins plus 2 additional spins per extra retriggering scatter.
Where available, players can purchase the bonus round through the bonus buy menu for 75x your stake. This guarantees 3+ triggering scatters on the following spin.
