Hollow King by Crypt Games Slot Overview

Hollow King by Crypt Games wraps its Halloween theme in black-and-orange artwork, gothic lettering and haunted-house imagery. Its cluster wins and tumbling symbols share a foundation with Sweet Fiesta, but carved board positions develop into lantern multipliers, giving the spooky setting a distinctive mechanical role.

Lantern Spots build multipliers up to x4096 and remain lit throughout Haunted Night, adding progression to this high-volatility slot. Trick or Treat awards bonus enhancements before free spins, while the maximum win reaches 50,000x the bet. Explore these features in the free demo on BonusTiime.

Hollow King Slot Features

Hollow King packs in Cluster Pays, Lantern Spots, Potion Cauldron, Witch’s Flight, Haunted Night, and Trick or Treat, with each feature adding another layer to the bonus flow and board-building action.

Lantern Spots

Every winning position leaves a carved mark. If that spot wins again, it lights a lantern worth x2, then doubles on each new win up to x4096. The lanterns stay on the spot, not the symbol, and they persist across the full Haunted Night bonus.

Potion Cauldron

Every symbol that pops drops into the cauldron, and any drop can make it boil over once per spin. When it does, the witch brews one potion. The game can award these results: Wild Brew, Transmute, Lantern Surge, or Multiplier Potion.

• Wild Brew: 4 to 7 Wilds.
• Transmute: every A or every K turns into one premium symbol.
• Lantern Surge: every mark and lantern grows one step.
• Multiplier Potion: x2, x4, x8 or x16 on 3 to 8 spots, or the whole board.

Witch’s Flight

On any spin in the base game or Haunted Night, the witch can sweep across the board before wins are counted. She turns 3 to 6 symbols into Wilds, which can link into several clusters at once and improve the tumble sequence.

Haunted Night

4 Haunted Houses start 10 free spins, 5 Haunted Houses start 12 free spins, and 6 Haunted Houses start 15 free spins. Before the free spins begin, Trick or Treat lets players choose from 9 doors, with the first door always awarding a treat and a trick ending the knocking. Treats can add spins, lanterns, or a Hot Cauldron.

Witch’s Potion

This buy feature lets players switch on a costly boosted mode before a round starts.

• Ante 3X: x3 the bet per spin; Haunted houses land more often.
• Ante 6X: x6 the bet per spin; Haunted houses land much more often.
• Witch’s Potion: x500 the bet per spin; every spot gets a lantern from x2 up to x4096.
• 4 House Bonus: x100 the bet; 10 free spins, Trick or Treat with 3 tricks behind 9 doors.
• 5 House Bonus: x250 the bet; 12 free spins, Trick or Treat with 2 tricks behind 9 doors.
• 6 House Bonus: x500 the bet; 15 free spins, Trick or Treat with 1 trick behind 9 doors.

Hollow King Slot Review

Hollow King leans hard into a Halloween storybook look, but the real identity comes from the board itself. The black background, orange highlights, haunted houses and gothic framing give it a clear spooky profile, while the lantern markers add a mechanical layer that keeps the theme tied to play.

The strongest idea here is the Lantern Spots system, because marked positions can climb to x4096 and feed into later wins. That gives the high volatility some purpose, and the Trick or Treat path into Haunted Night adds progression before the free spins even begin. The buy menu is broad, though it also pads the package.

Hollow King suits players who want a cluster slot with clear feature structure and a maximum win of 50,000x the bet. The 50,000x max win and the bonus options give serious upside, but the game asks for patience. It suits feature hunters more than players who want simple base game action.
