Zombie Outbreak uses a five-reel board whose rows alternate between four and five, then builds its feature around Expanding Wild symbols and three collectable multipliers. The official description ties collection to a win: when players win, they can collect multipliers from Expanding Wilds. Separately, three Scatters can trigger 15 Free Spins. This gives the game two visible routes—a win-linked multiplier collection and a Scatter count—without saying that either guarantees a particular payout. The catalog does not explain how the three multipliers are chosen, whether they persist across spins, or how the Wild expands. Those details matter more than the zombie setting when assessing the actual mechanics.

A five-reel board with uneven heights
PG Soft lists five reels, with four rows on reels one, three and five and five rows on reels two and four. The official summary does not state a payline count or full symbol paytable. This 4-5-4-5-4 layout should not be simplified into a regular five-by-five grid; the outside and center reels are shorter than the second and fourth. The main described special symbol is an Expanding Wild, but the catalog does not specify which reels it may land on or how many positions it can occupy.
The entry links multiplier collection to winning: when players win, they can collect multipliers from Expanding Wild symbols. That wording makes a win relevant to collection, rather than saying the multipliers automatically pay when a Wild appears. It does not tell us whether the Wild must be part of the win, whether all visible Expanding Wilds contribute, or whether the collection happens once per spin. Nor does the source say whether the three collectable multipliers are fixed values, selected values or a count of three possible awards. A reader can follow the basic relationship, but cannot reconstruct the complete collection process from the catalog entry alone.
Three multipliers and the Scatter feature
The provider calls the multipliers collectable and identifies three of them. This suggests a finite set of multiplier elements, but the listing does not say whether each is collected permanently, reset after a win, or attached to a later feature. It also provides no values or cap for each multiplier. The term “Expanding Wild” confirms an expansion property but not its direction, timing or persistence. Each of those details could materially change how subsequent spins are evaluated, so none should be supplied by inference.
Three Scatter symbols appearing on the reels can trigger 15 Free Spins. The summary does not state whether Scatter positions matter, what extra Scatters do, or whether Free Spins can retrigger. It also does not explicitly say whether collectable multipliers carry into the bonus or whether Expanding Wilds behave differently there. The two features are both confirmed, but their interaction is not. A useful comparison point is that the Scatter rule gives an explicit trigger count and spin award, while the multiplier feature has a win-related condition but no published value schedule. The 5,000x maximum cannot fill that gap.
Configuration for the listed version
The standard catalog record lists maximum RTP 96.75%, volatility value 3 and maximum win 5,000 times the bet. The RTP may vary by operator, and the source does not explain the numeric volatility scale. Release date is June 4, 2024. The listing supplies no payline count, multiplier values, collection persistence, Scatter retrigger condition or feature probabilities. These figures describe the catalog version and its stated ceiling; they are not a forecast of how often the collectable multipliers appear or how much a particular win returns.
Strengths and weak points
Strengths
Multiplier collection is explicitly linked to winning, and the three-Scatter trigger offers a separate, countable route to a fixed 15-spin feature.
Weaknesses
The catalog omits multiplier values and persistence, Wild expansion behavior and bonus interaction, leaving the collection sequence and its limits unclear.
Our Editor’s View
Zombie Outbreak has a clear link between a win and multiplier collection from Expanding Wilds, plus a separate three-Scatter route to 15 Free Spins. Its uneven reel heights give the board a recognizable shape, while the feature values and persistence rules remain unstated. That makes the central idea easy to understand but the sequence difficult to quantify. Players who like mechanics where a win can affect a later multiplier state may find the concept interesting. Those wanting a precise account should consult the game’s help rules for the Wild expansion, collection timing and whether the multipliers carry into Free Spins. The 5,000x maximum is only an upper bound; it does not establish the frequency or typical size of a collected multiplier result.
