How to cite

Slot Summary

Take a standard spin or use the Bonus Buy route: that choice determines how directly Zombie Outbreak reaches its free-spins pressure. PG Soft combines collapsing reels with expanding wilds that carry collectable multipliers, giving each sequence a clear survival-game rhythm. High volatility, a 96.76% RTP, and an x5000.00 ceiling place the main emphasis on multiplier-assisted chains rather than steady line hits.

How It Plays

Each standard spin checks 1600 ways across five reels. Winning symbols collapse out of view, allowing replacements to fall into their positions and produce another result.

Wild symbols can expand when they appear on the relevant reels. Their three attached multipliers are collected in sequence, adding a second calculation to each collapsing win chain.

Theme & Atmosphere

Zombie Outbreak treats its Apocalypse and Zombie themes as a survival scenario, using the threat of a spreading Virus to give the reel action urgency.

Guns, Medicine, and Science provide the human response to the Horror setting, while Magic adds a less clinical strand to the outbreak premise.

Features & Win Potential

Expanding Symbols and Wild Multipliers work together: an eligible Wild Symbol covers more reel space and supplies collectable values that can raise a qualifying win.

The Random multiplier and Multiplier features matter most when repeated collapses keep a round active. That interaction suits the stated High volatility profile and x5000.00 limit.

Bonus & Free Spins

Three Scatter Symbols award 15 Free Spins, with each additional scatter adding two more. The round retains the expanding-wild concept while offering more opportunities to collect multipliers.

Bonus Buy provides a direct route to the bonus content for players who prefer immediate access instead of waiting for a natural scatter trigger.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.76%), with wins capped at its top multiplier (5,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
