Zombolics Slot by Onlyplay

Wilds on the middle three reels stick during free spins and keep whatever multiplier they landed with - x2 or x3. That's the one mechanic doing all the work here. Land enough of them across reels 2, 3, and 4 over 7 to 12 rounds, and the grid gradually fills with locked multiplier wilds that compound through every remaining spin. Reels 1 and 5 don't get sticky wilds at all, so the edges stay active while the center slowly builds. For 75x you can buy straight into the feature, which guarantees three or more of the green bubbling scatter potions and starts the free spins immediately.

The setting is a comedy zombie office - trashed cubicles, CRT monitors with cracked screens, sticky notes and charts pinned to a background wall that looks like it hasn't been cleaned since the outbreak. Symbol art leans fully cartoonish: a green-skinned businessman clutching a briefcase, a purple-haired zombie scientist in a lab coat, and a dozen office supply lows - calculators, staplers, ID badges, pencil cups, drumsticks (lunch, presumably). The buy button itself is styled as a torn yellow sticky note pinned to the left side of the screen. OnlyPlay runs a similar horror-comedy vibe across several titles but this one is simpler, built around that single sticky wild accumulation loop with no second bonus layer or jackpot structure underneath.
