Slot Summary

Yggdrasil puts its Gigablox mechanic at the center of Giga Zombies, using oversized symbols to interrupt a 6-reel Scatter Pays field. Winning groups vanish through Avalanches, and consecutive results can unlock modifiers or raise multipliers before the grid settles. The Horror and Zombie setting gives those sudden scale changes a destructive tone, while the x6260.00 ceiling and high volatility keep the math pointed toward less frequent peaks.

How It Plays

Giga Zombies uses Scatter Pays instead of fixed lines. Matching symbols may connect from anywhere on the grid, and successful groups disappear before replacement symbols fall.

Each Avalanche can produce another qualifying group on the same wager. Consecutive results also move the modifier meter, creating chances for Wild drops, Multiplier increases, or larger symbols.

Theme & Atmosphere

The Horror setting combines a zombie outbreak with ruined jungle structures and an armed survivor. Its dark treatment gives each Avalanche the sense of another breach in the scene.

Zombie characters occupy both regular and oversized forms, so the theme remains visible when Gigablox changes the scale of the reel field. The presentation favors disorder over comic horror.

Horror Zombie

Features & Win Potential

Gigablox and Mega Symbols can occupy multiple grid positions, while Cascading removes every winning group. Their interaction can replace a scattered set of symbols with a much larger matching block.

Wild Symbols and Multipliers may enter through Avalanche modifiers. These additions affect the current chain before the grid settles, giving repeated wins more mechanical consequence than isolated hits.

Bonus & Free Spins

Free Spins carry an increasing Free Spins Multiplier, so continued Avalanche wins can raise the value applied to later results within the same feature.

Additional Free Spins may extend the round, while Gigablox, Cascading, Scatter Symbols, and Wild Symbols remain active. The feature preserves the base game's large-symbol and repeat-win emphasis.

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 (96.00%), with wins capped at its top multiplier (6,260×).

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.
