Polterheist Slot by Light & Wonder

Two random base-game modifiers can fire on any wagered spin, but never together. Ghost Break-In drops in first - one ghost symbol appears and turns every other ghost on screen into a copy of itself, then adds stacks of that same ghost across the reels. The OAK potential balloons in one move. Haunted Wilds takes the other path: 2, 3 or 4 extra Wilds get pasted onto reels 2, 3 and 4 before the spin resolves. Both run silently in the base game, both also fire inside Free Games (and reportedly more often there per the in-game help text), and when one triggers the other is locked out, along with the free-spins trigger itself. So a Ghost Break-In spin can't also drop the Safe scatter combo. That trade-off is the engine of the volatility.

The Safe scatter only lands on reels 1, 3 and 5, and you need one on each of those three reels to open Free Games. The award is 8 spins, with every win multiplied by a random 2x, 3x or 5x. Retriggers pull from the same scatter pattern: one extra Safe inside the round adds 1 spin, two adds 5, three adds 8. The multiplier rolls fresh per win, not per spin, so a Haunted Wilds boost during free games can stack a 5x onto a fully wild middle band - that's where the 2,500x ceiling becomes reachable, via the top ghost symbol Goldie Goldrush filling the screen with wild assistance and a 5x roll.

The Wild itself only shows up on reels 2, 3 and 4. It substitutes for everything except the Safe, which means it can't help you complete a scatter trigger but it does most of the line-pay heavy lifting. The 100 paylines are fixed at 50 coins per spin (half a coin per line), and pays settle left-to-right on consecutive reels only - no both-ways scoring here.

The reels sit inside a haunted saloon, carved wooden columns draped in cobwebs, candles flickering at the corners, midnight sky visible past the cabinet sides. The cast is four cartoon ghost outlaws: a mariachi-style ghost in a red sombrero, a yellow-hatted cowboy ghost with a pistol, a purple-cloaked outlaw, and a green slime ghost. A WANTED DEAD parchment poster acts as the Wild, neon J/10/Q/K/A royals fill the lower paytable in pink, orange, blue and white, and a gold vault Safe carries the scatter role. The POLTERHEIST logo crowns the cabinet in pink and yellow blackletter. Side City Studios built this for NextGen in 2018, and it carried over when NextGen folded into SG Digital and then Light & Wonder. No buy bonus, no ante toggle, no gamble - just the two random modifiers and the scatter route into free games.
