Infestation Mechanics

How the 25,000x Plague Actually Works

Extreme volatility Sneaky Slots title. xWays expansion, Toxic Spill bonus, Larvae respins, and the rarity of the max win.

Infestation xWays — From 1,024 to 110,592 Ways

Standard grid is 5×4 (1,024 ways). Random symbols can trigger xWays expansion, transforming into a swarm of cockroaches that covers 2–8 positions per reel. Peak configuration: 8×8×8×8×8×4 = 110,592 ways.

Way-count scales geometrically. At 4 reels expanded to 8 positions, you reach 32,768 ways — dense enough that any premium symbol on the 5th reel triggers massive line-hit counts.

Toxic Spill Bonus — Sticky Wilds + Multipliers

Land 3 Radioactive Barrels to trigger Toxic Spill. Free Spins with a twist: all Wild symbols that land during the bonus become sticky and carry random multipliers (x2–x25). Each Wild stays in place for the entire bonus.

Multiple sticky Wilds contributing to the same win multiply their multipliers together. Two Wilds at x10 + x25 = x250 on a single way. Natural trigger rate: ~1 in 250 base spins.

Larvae Respins — Winners Leave Residue

When a winning cluster pays, the positions leave behind larvae symbols that persist to the next spin. On the following spin, each larva hatches into a random high-value symbol or a multiplier wild.

Hatching distribution: ~60% high-value regular, ~30% Wild with x2–x5 multiplier, ~10% mega-Wild x10+. Larvae chains are rare (appearance ~1 in 15 winning spins) but produce the "follow-up explosion" wins — ~80x+ sequences on 1 in 200 base spins.

Swarm Mutation — Full-Grid Transformation

A "swarm meter" charges with cockroach symbols across base-game spins. When full (rare — ~every 200 spins on average), the next spin is a Swarm Mutation: every grid position transforms into a high-paying parasite symbol just before payline evaluation.

This effectively pays out the entire grid at premium 5-OAK values × ways-count. A single Swarm Mutation spin typically clears 800x–2,000x depending on which parasite symbol fills.
