King of Ghosts Slot by Endorphina

Most expanding-wild bonuses just spread a substitute across a reel and move on. King of Ghosts adds a second layer on top, and it only fires inside the free games. After any free spin that pays, ghosts swarm in to steal the win, and Zhong Kui, the ghost-catcher of Chinese folklore who doubles as the wild here, has set out baited cages each holding a value of x1, x2, x3, x5 or x10. Once every ghost is caged, the surviving multiplier gets applied to that spin's payout. One catch worth knowing: that multiplier touches the cash only, never the count of extra spins you retrigger.

Three or more scatters start the round with 12 free games, won again from inside itself if more scatters land. The other thing running through those spins is the expanding wild. Zhong Kui stretches to fill his whole reel, but only when the stretch actually completes a win, so he won't waste a column padding a dead spin. Stack that against the Ghost Catcher and a single good free spin can land a fat line and then have it caged up to ten times over. Scatters pay from anywhere on their own, and their value adds on top of any line wins in the same spin, base game included.

If you'd rather not chase the trigger, the Bonus Pop button buys the 12 free games outright, its price scaling with your stake, and the bought entry opens on a base spin that drops the three scatters for you. Anything Bonus Pop pays is locked out of the Risk Game afterward. That gamble is the standard Endorphina card draw, beat the dealer's face-down card to double, repeat up to ten times, joker beats all and never lands in the dealer's hand. Sitting underneath everything are the network mystery progressives, Grand, Major and Minor, drawn at random with bet size nudging the odds.

The board is warm and unhurried for a Chinese-mythology slot. The reels rest on a parchment-gold panel bordered by carved dragons and temple eaves, set against misty golden peaks and tiled roofs glowing under a sunset sky. Premiums are oriental treasures, a red yin-yang disc, a gold folding fan, a smiling lucky charm, a gold ingot, a jade amulet and an ornate dagger, with engraved 9 10 J Q K A royals beneath them in imperial red and jade.
