Different Types of Halloween Slots

Halloween stretches much further than the 31st of October. Celebrated worldwide, you’ll find countless horror films and television series. Movies like The Exorcist, Saw, The Evil Dead, Alien and Beetlejuice are iconic.

There has also been a surge of true crime and serial killer documentaries which have played their part in popularising Halloween-inspired slots. They stimulate mental and physical effects which can lead to fear, anxiety, joy and even excitement.

Below, you’ll find a list of the various types of Halloween slot games you’ll encounter at slot and casino sites:

  • 🧟 Zombie Slots: Films like Night of the Living Dead and Shaun of the Dead as well as TV series such as The Walking Dead make zombie slot games very popular. Playtech has released several official The Walking Dead slots. Other popular choices include 4ThePlayer’s 1 Left Alive, Hacksaw Gaming’s Rotten and Pragmatic Play’s Wild Walker.
  • 🧛 Vampire Slots: With movies such as Twilight and The Lost Boys, there are various vampire slots such as NetEnt’s Halloween Jack, Hacksaw Gaming’s Bloodthirst and Play ‘n GO’s Wild Blood.
  • 💀 Day of the Dead Slots: Celebrated the world over, it’s closely linked to Halloween and has inspired several slot studios with games such as Thunderkick’s Esqueleto Explosivo, Yggdrasil Gaming’s Calavera Crush and Play ‘n GO’s Muerto en Mictlan popular options.
  • 👻 Ghost Slots: Popularised by films such as Ghostbusters, ghost-inspired games include Play ‘n GO’s Ghost of Dead, Quickspin’s Ghost Glyph and IGT’s Ghostbusters Plus (official game).
  • 🐺 Werewolf Slots: I particularly like Pragmatic Play’s Curse of the Werewolf Megaways, NetEnt’s Blood Suckers 2 and Playtech’s Full Moon Fortunes.
  • ⚰️ Horror Slots: There are countless generic Horror-themed games like Skywind’s Alive! Megaways (inspired by Frankenstein), Nolimit City’s Beheaded and Hacksaw Gaming’s Undead Fortune.
  • 🧙‍♀️ Witch Slots: Witches are also popular with 4ThePlayer’s 3 Lucky Witches, Microgaming’s Mega Moolah: The Witches’ Moon and of course Playtech’s Halloween Fortune.
  • 🩸 Serial Killer Slots: The rise of slot games based on notorious serial killers is on the rise with Nolimit City releasing Serial, Disturbed and Kiss My Chainsaw.
  • 🕸️ Mummy Slots: Playtech’s The Mummy: Books of Amun Ra is the official game from the iconic film series. You also have Play ‘n GO’s Legacy of Dead and Rise of Dead.
  • 🎥 Branded Slots: Many slot providers have released official/branded games with licenses from movies or TV series. They include The Walking Dead (Playtech), Lordi Reel Monsters (Play ‘n GO) and Beetlejuice Megaways (Light & Wonder).
