Space Goonz Slot by Habanero

Eleven different cartoon aliens spill across the reels here: a one-eyed orange blob, a purple porcupine creature with worried eyes, a red crustacean thing, a green lizard with spines, a blue droid wearing what looks like a chain harness. Behind them, a yellow space-tank, the nose cone of a rocket, and chunks of rubble drift across a violet planet horizon. It's deliberately overloaded, with the space setting acting less as backdrop and more as a busy diorama crowded against the reels. The CarismaGothic logo up top renders in that pink-and-blue chrome lettering 80s arcade flyers used to wear.

The robotic red robot icon is doing two completely separate jobs that most slots split across two symbols. It substitutes as a Wild on the base game paytable. It also triggers Free Spins directly when 3+ land anywhere on the reels, with no dedicated scatter in the math at all. The tier scaling is wide: three Wilds award 10 spins, four push it to 20, and a full five-Wild landing drops 50 free spins, which is the highest scatter-tier free spins count Habanero builds into any of their cabinets. The trigger and the substitute are the same physical icon, so a hot spin that pays a line of three Wilds also pays out as a top-tier combo at the same time it sends you into the bonus.

Inside Free Spins the same Wild count flips into a second mechanic. Two or more Wilds landing in a single free spin triggers Symbol Upgrade: a random high-paying alien gets permanently swapped for an even higher-paying one for the rest of the round. The upgrade is cumulative, so a second trigger inside the same bonus shuffles another symbol up the ladder, and the paytable keeps climbing as you go. Retriggers stack the spin counter on top of that, which is how the 3,624x ceiling actually gets built out: not from a single huge line read, but from a free-spin round that's been escalated three or four upgrade levels above where it started. There's no buy-feature shortcut into any of it, and no ante-bet chip to push trigger odds, so the only way into the round is to land the Wilds organically.

Twin random progressives sit above the playfield, Minor on the left meter and Grand on the right, both drawable on any paid spin without a symbol condition. Audio is doing a surprising amount of work in the background, with a three-state music engine that swaps between idle, spin and free-spin tracks rather than looping one bed, and a five-stage big-win celebration that escalates through megawin into a supermegawin tier when a payout breaks the top threshold. The Symbol Upgrade trigger gets its own dedicated three-sample sound package, separate from everything else in the cabinet, including a popup hit when the upgrade is announced and a reel-only variant when it fires mid-spin.
