Rich Little Piggies World Class Halloween Edition Slot by Light & Wonder

Picture a chubby ghost pig peeking out from behind a tombstone next to a vampire pig in a black cape and a jack-o-lantern-headed witch pig grinning from under the moon. That's the cast Light and Wonder dressed up for this 2025 Halloween reskin of the World Class engine, swapping the original farmyard sunshine for a graveyard backdrop of twisted bare trees, purple-bruise sky and bats fluttering across an orange-red horizon. The card royals get the same treatment, glowing purple A/K/Q/J/10 with tiny pumpkins and ghost faces tucked into the J and K.

The mechanic everyone wants to know about is the Purple Pig variant, because it's the one with teeth. Land the Ghost Pig coin and you trigger Free Spins with a Wild Multiplier and Roaming Mystery Reveal Doors on reels 2, 3 and 4. Up to six doors drift around the middle reels (positions reshuffle every spin) and any payline running through them is multiplied by whatever value the Purple meter has climbed to. That's how this Halloween edition pushes its ceiling slightly past its Christmas hen sibling and tops out at 13,350x stake.

The Red Pig coin (the cop-hatted Captain Cluck-equivalent, somber as ever) runs Standard Free Spins on a meter that caps at 40 spins, resets to 9 after the round, and ticks up by one for every extra Red coin that lands during the feature. Yellow Pig sends you into Jackpot Free Spins where Mystery Doors crack open to reveal jackpot icons, and you need to fill six positions for MEGA, five for GRAND, all the way down to two for MINI and MINOR. MEGA pays $25,000 and GRAND $1,500 on a $2 stake (both fixed), while MAJOR through MINI reset on payout.

The base game leans on Mystery Stacked Reels, where a column of Mystery Doors uniformly snaps open to the same random symbol, occasionally with a pig coin sitting on top. Land two different coin colors and the feature upgrades mid-round, so Red plus Purple becomes the Wild Multiplier variant with a head-start on spin count. White coins inside the bonus spin up a small wheel for extra spins or a fresh feature layer.

No buy bonus, no ante, no gamble. The whole game is built around getting that Ghost Pig to show up on the right spin.
