SYMBOLS
Playing cards 10 through ace are the title’s low-value symbols, offering between x0.1 and x6 the player’s bet depending on how many of each symbol are present on the reels after each spin or avalanche.
Blue, green, purple and orange zombies are the game’s high-value symbols, offering between x0.75 and x25 the player’s wager depending on how many of each symbol land on the reels after each spin or avalanche.
A gold chalice is the title’s wild symbol, which substitutes for all other paying symbols on the reels. A free spins logo is the title’s scatter symbol, offering between x1.5 and x50 the player’s stake depending on how many scatter symbols are present on the reels after each spin or avalanche.
DETAILS
Players must land eight or more identical symbols on the reels to win, with each symbol that is part of a winning round being removed from the reels for new symbols to fall into place through the avalanche.
The game has a progress bar, which fills up by one after each successful avalanche win, resetting after the avalanche session is over.
Four wins will spawn a random Gigablox symbol onto the reels (2×2, 3×3 or 4×4). Six wins will cause one to four wilds to fall onto the reels before another avalanche. Nine wins will trigger free spins mode.
Free spins will be triggered if the player lands four or more scatter symbols on the reels in the base game, with the mode beginning with eight free spins. A random Gigablox symbol is also guaranteed to land in each spin. Three or more scatter symbols landing during free spins will award eight free spins alongside the standard payout.
The progress bar will also change to feature multipliers up to x50 with each avalanche win, moving the player one spot on the bar, awarding a higher multiplier. The multiplier is awarded at the end of every avalanche win before the progress bar resets. Nine or more avalanche wins will award eight free spins.
Three different features can trigger at random during a non-winning spin – Zombie Horde, Chaos Kingdom and Lucky Gigablox.
Zombie Hoard turns a random number of regular symbols into high-value symbols in a winning combination. Chaos Kingdom will turn a random number of regular symbols into random symbols in a winning combination. Lucky Gigablox will turn a random 2×2 regular symbol cluster into a Gigablox symbol in a winning combination.
The title also has a buy bonus, allowing players to purchase eight free spins for x100 the player’s stake.
WHAT THEY SAY
Marcin Tomala, Senior Game Designer at Yggdrasil, said: “We had a lot of fun brainstorming this game’s vision. The main inspiration behind Giga Zombies was to combine the excitement of classic adventure movies with the action and chaos of a zombie shooter.
“We wanted players to feel like they’re joining a treasure hunt deep in an ancient Aztec world, blasting through hordes of undead on the way to hidden riches. The game’s higher volatility really supports that fantasy too—every spin feels like taking another risk in search of a big reward, and I’m excited to see how players react to that experience.”
