Trick Or Treat Slot by Genii

A moonlit Victorian house broods in the back, gnarled tree silhouettes claw in from both edges, and a faint blue-grey full-moon glow washes the reels. The "TRICK OR TREAT" logo drips down in blood-green Halloween-comic lettering. Costumed kids carry the symbol set: a ghost in a white sheet, Little Red Riding Hood, a hockey-mask kid with an axe, and a wolf-mask kid. Tricks (red devil pitchfork, fake-blood vampire-fang bottle, cracked egg) sit next to treats (swirly lollipop, candy bag, and a glowing Jack-o-lantern with "WILD" carved into it). It's mischievous, not scary.

The grid is a standard 5x3 with 30 player-selectable paylines, but the symbol set isn't standard at all. There are no card values. Every paying icon is themed, which matches what Saucify did on a handful of its mid-decade titles. The Pumpkin Wild substitutes for everything except the scatter, and the top two line symbols plus the Wild even pay 2-of-a-kind, which is rare for this batch. One quirk: the Wild itself only pays 100 coins for 5-of-a-kind, well below the top line symbol's 6,000. Useful as a substitute, weak as a winner on its own.

Three, four, or five scatters trigger 10, 15, or 20 free spins with all wins doubled, and the round retriggers if more scatters land. After any paid win you can hit the Gamble button: card colour for x2 (50/50) or card suit for x4 (1-in-4), repeatable until the cap. Worth flagging that Genii actually exposes Gamble in the demo here, where most of their other Saucify-engine titles leave it disabled.

The headline number is the 97.17% RTP, which sits at the top end of the Saucify batch (most of these 2015-era builds run 95-96%). Volatility plays medium-high. Bet range covers $0.01 up to $37.50 per spin across four chip tiers and five coins per line. No buy-bonus, no jackpot, no progressive layer. And for a 2015 release it still holds up as a tidy little Halloween spinner with one of the more generous maths models in its sibling set.
