Giganimals Gigablox Slot by Yggdrasil Gaming

Open the cabinet and four collection meters are already partway full. The four UFO ships running down the left rail show 336/480 for the rooster, 240/480 for the ram, 96/480 for the pig, and 48/480 for the sheep on a fresh play - a head start the game just hands you. Each meter feeds off its matching low-pay symbol. Every payline win that contains a low symbol drops points into the corresponding ship, the count equal to how many cells the win passed through, and a random per-spin multiplier between x2 and x5 can boost the haul before it lands in the meter. Wilds do not feed any meter.

The other base-game wrinkle is Wild Surge. It fires randomly on any base spin, and when it does between 1 and 4 of the four low-pay tiles on the visible grid convert to wilds at the end of the reel stop. Crucially, those converted lows still count toward their meters before they pay out, so a Surge spin pulls double duty. Gigablox blocks layer on top of all of this - any reel can drop a 2x2, 3x3, or 4x4 mega-symbol that scores as multiple individual symbols across the 40 fixed lines, which means a Gigablox low symbol can dump a stack of points into one ship in a single spin.

Two routes into Free Spins. Filling any meter awards 5 to 20 spins where that meter has its low symbol turn wild for the round. The remaining meters reset to a much smaller 25-symbol target, so secondary fills are realistic - each one adds +2 spins and converts another low to wild. Five or more Bonus scatters in view trigger Scatter Free Spins instead, one spin per scatter, with no wild conversion. After either trigger, the Free Spins Gamble wheel offers a chance to push the total spin count up to 24. Lose the gamble and the entire bonus evaporates.

Three Buy Bonus tiers cover the lazy options: 75x for random scatter free spins, 150x for a guaranteed 24 scatter spins, and 250x for 24 collection spins with one low pre-set as wild. The cabinet sits against a dusky pink-red sky with mushroom trees and UFO silhouettes on the horizon, the ships in alien neon lighting up the meters. The other Gigablox cousin Lucky Apocalypse Gigablox chases mega-symbols through a wasteland setup, but Giganimals routes the engine through which animal you fed rather than which Gigablox stack happened to land.
