Bad Santa Slot by Peter & Sons

Twisted little goblins with candle flames flickering on their heads, pink and green candy swirls scattered everywhere, and a snowy mountain cave glowing cold blue behind the grid. The dark Christmas angle here is genuine - these aren't cute elves. Four monster characters in red, blue, green, and purple fill the high-pay slots, each one dripping wax and grinning with too many teeth.

Scatter pays need 8 or more matching symbols anywhere on the grid, no adjacency required. Wins cascade out and new symbols drop in from above, and every consecutive cascade doubles the active multiplier: x1, x2, x4, x8, x16. That doubling resets between spins in the base game. During free spins it doesn't reset at all. Seven free spins from 4 scatters, each additional scatter adds 2 more, and the multiplier just keeps climbing for the entire round. No retrigger, so whatever cascade chain you build is what you get. A Multiplier Jump can randomly bump the multiplier up one tier mid-cascade, and it fires up to three times in a row - so a single cascade could jump from x2 straight to x16 without the intermediate steps. Gift boxes stacked on the left side of the reels track your current position. For 100x you can buy 7 free spins directly, or 200x gets a random allocation between 7 and 11.

Golden Bet is priced at 1.2x instead of the usual 1.5x most Peter & Sons games charge, and it only adjusts scatter trigger frequency. A candy cane progress bar stretches across the bottom of the screen, and the whole grid sits inside an icy border dusted with snow, bordered by string lights that blink against the dark rock face behind.
