King of Ghosts Slot Overview
Zhong Kui, the demon-catcher of Chinese folklore, gets his own 20-line slot here, and everything in it points at one round. Three yin-yang banners hand over 12 free spins. That is where he stretches across a whole reel, and where ghosts turn up after every win to try to carry it off before Zhong Kui shakes a multiplier out of them.
Endorphina released it in February 2022 and kept the frame deliberately old-fashioned: 5x3, wins from the left, no ante bet, no ways engine, no meter ticking along under the reels. What it has instead is a 25,000x ceiling, which exists only because a full-reel wild and a x10 can land on the same free spin, and 96.01% RTP with high volatility to get there.
Theme & Design
The art sits inside a sunset. Hazy sandstone peaks streaked with pine fill the background, a small red pagoda clings to a cliff on the left, temple roofs fade into the haze on the right, and the whole sky burns orange behind it. The reels are a parchment panel printed with faint cloud scrollwork, boxed in by a gilded pagoda frame with curled eaves, and the red lacquer logo plaque hangs above with the two characters for Zhong Kui picked out in gold.
Symbols split cleanly in two. Premiums are painted objects on coloured tiles: a folding fan with red brushwork, a gold ingot glowing against green, three coins knotted with red cord, an ornate sword half-drawn on purple, and a winged gold charm that is the best-drawn thing on the board. Royals are engraved gold letters with coloured cores, capped like little pillars, and they occupy most of the grid most of the time. The palette is handsome and completely familiar, a hundred Chinese mythology slots have used this exact gold-and-jade mix. Only the yin-yang bagua on its hanging red banner really jumps off the parchment.

Features & How They Work
Free Games with the King of Ghosts feature
Three or more Scatters anywhere award 12 free spins at the triggering bet and line count. During them Zhong Kui becomes an expanding wild: he covers all three positions on his reel, but only when that expansion actually completes a win, so he stays a single symbol on spins where a full reel would pay nothing. Another three Scatters inside the round add 12 more spins, and there is no cap on retriggers.
Ghost Catcher
The part worth loading the game for. After any free spin that pays, ghosts appear and go for the win. Zhong Kui has hidden bait in cages carrying x1, x2, x3, x5 and x10, and once every ghost is caged, the multiplier left standing is applied to that spin. It is a genuine coin flip on value: x1 is one of the five outcomes, so a fair share of winning free spins get all the ceremony and no uplift. The multiplier never touches the number of extra spins won.
Bonus Pop
The bonus buy costs 122x the total bet and can be pressed at any point, so 24.40 at a 0.20 stake. The purchase plays out honestly: it spins the base game once, lands three Scatters, and rolls into the same 12 free spins. Winnings from a bought round cannot be sent to the gamble. Some operators switch the button off entirely.
Risk Game
The old Endorphina card gamble. One dealer card faces up, four face down, pick one higher to double, up to ten times in a row. A Joker beats everything and the dealer never draws one, equal values push. The average return on it is 84%, well below the game itself, so it is a way to have fun with a win rather than a way to build one. Locked out during autoplay, and jackpot or Bonus Pop money is not eligible.
Progressive Mystery Jackpot
Three networked levels, Minor, Major and Grand, drawn at random with no trigger to hit and no player input. Higher stakes improve the odds of being drawn, and the bet has to sit inside the allowed range to qualify at all. Whether it is running depends on the casino, and plenty of operators leave it disabled.

How King of Ghosts Plays
Most of a session is card royals. Engraved 9s and Js fill the board, a fan or an ingot drops in for a small line win, the balance drifts down in 20-line steps. Nothing accumulates while that happens. No meter, no collection, no near-miss theatre beyond a couple of bagua banners landing one short of the trigger.
Then the round starts and the pacing flips. Twelve spins go fast, but each paying one halts for the ghost scrap, and that little interruption gives the round more shape than a straight free spins counter ever gets (it is also the only time the game raises its voice). A x1 reveal after all that build-up stings more than a plain small win would, which will probably happen a good deal more often than the x10 does.
High volatility here means what it usually means. The trigger is the session, and everything before it is waiting. Playing at a stake that survives a few hundred spins gets there eventually. Playing at the top of a bankroll mostly meets the royals.
Pros & Cons
Pros
- Ghost Catcher gives every winning free spin a second beat instead of just paying and moving on
- Full-reel wild stacked with a x10 multiplier gives the bonus a proper top end
- Bonus Pop at 122x is cheaper than most buy features on the market
- Retriggers are uncapped, so a hot round can run long
Cons
- Base spins carry no extra layer at all, which makes the wait between triggers a grind
- x1 is one of the five Ghost Catcher outcomes, so plenty of bonus wins pay flat
- 84% average return on the card gamble is a poor deal next to the game itself
- Jackpots and the buy button are both operator-optional, so two casinos can run noticeably different versions
Is King of Ghosts Worth Playing?
Strip the ghosts out and this is a 2010-vintage line slot in good clothes. The Ghost Catcher is what rescues it. Turning each winning free spin into a small fight over the payout is a smarter idea than another multiplier meter, and it makes a short round feel like an event rather than a countdown.
The problem is everything around it. Base spins have nothing going on, high volatility stretches the gap between triggers, and Endorphina put a price tag on skipping the wait at 122x, which says plenty about where the game keeps its value. Zhong Kui deserved a slot with more happening on the reels he actually appears on most of the time.
