Giga Zombies Slot by Yggdrasil Gaming

A red-haired explorer in a leather vest and wide-brimmed hat stands above the reels, twin revolvers raised, with a green-tinged mist curling around crumbling Aztec stonework behind her. Vines hang off the wooden bracket holding the grid, skulls litter the periphery, and the occasional zombie shuffles in the murk. The royals pop in saturated colours (purple Q, gold K, green J), and the high pays are glowing skull faces washed in red, blue and acid green. It's pulpy B-movie stuff with a metal soundtrack underneath.

Mechanically, Yggdrasil has been recycling this exact engine across a couple of recent titles, so if you've played the leprechaun-with-guns one, you already know how the bar works. Wins are scatter-pays, 8 of a kind anywhere on the 6x5 grid. Symbols tumble, new ones fall in, and a Progress Bar tracks consecutive Avalanche wins. Hit 4 in a row and a random Gigablox (2x2, 3x3 or 4x4) drops on the next cascade. Six in a row sprinkles 1 to 4 Wilds. Nine in a row sends you straight to the bonus, no scatters required.

The bonus is 8 free spins, and that same bar reappears, but now it's a multiplier ladder applied at the end of each Avalanche session. One win is x2. Get to eight consecutive wins and you're at x50. A ninth win retriggers another 8 spins. Every free spin drops a guaranteed Gigablox too, so you're not starting cold. The bar resets between sessions, which honestly stings when you spend a long cascade clawing up to x20 only to start again at zero.

On dead spins, one of three randoms can fire: Zombie Horde converts symbols into high pays, Lucky Gigablox plants a 2x2 cluster, Chaos Kingdom rearranges symbols into matches. The Buy Bonus is a flat 100x for entry with 4 to 6 scatters rolled in (the extra scatters add cash on top of the 8 spins).

The honest problem? This is the same math model and the same Progress Bar mechanic Yggdrasil already shipped under a different skin, and the reuse is hard to miss once you spot it. The art is genuinely fun, but if you're hunting fresh ideas you'll find the engine a little familiar.
