Zombie Blasters Slot by PG Soft

An Alarm symbol is the thing to watch for. It's a red siren light that can drop on any spin, and on its own it does nothing. But if it's sitting on the grid when a winning spin finishes, it fires the Multiplier Wheel mounted above the reels - a dial that lands somewhere between x5 and x50. Then comes the part that matters: the Alarm and every x2 Multiplier tile already on the grid all transform into that wheel value before the win pays. Five x2 tiles plus an Alarm, wheel rolls x30, and suddenly you're looking at six x30 multipliers stacked onto one win.

Without the Alarm, the x2 tiles still work, just quietly. At the end of any spin the total win gets multiplied by the sum of all multiplier values on the reels, so four x2 tiles means x8 on that win, not x2 four times over. Wins themselves land through scatter-pays - any 8 or more matching symbols anywhere on the 6x5 grid count, the winners explode, and fresh symbols cascade in to keep the chain going.

Free spins come from chest Scatters. Four chests gets you 10 spins, five gets 15, six or more gets 20, and three more chests during the round adds 5 each time. The bonus changes how the math accumulates: every multiplier you earn gets added together and parked at the bottom of the reels, staying there for the whole feature. At the end of each free spin the win is multiplied by both the on-reel multipliers and that running total at the bottom. The highest single multiplier the game hands out is x50, and the free spins are where the 10000x ceiling actually becomes reachable. A feature buy sells direct entry if you don't want to fish for four chests.

The whole thing is dressed as a pixel-art arcade cabinet. The reels sit inside a chunky blue machine with a fat red spin button and the wheel bolted on top, while the top-paying symbol is a goggle-wearing girl with twin red buns who shoots and slices her way through a zombie outbreak. Royals are blocky 8-bit 10/J/Q/A, the low symbols are green pixel blades, and the chests glow purple when they land. Retro 8-bit art over a polished 3D frame, and it reads more cheerful arcade than horror despite the zombies.
