The Best Halloween Slots to Play in the UK

Halloween takes place every year on the 31^st of October and has become celebrated worldwide with costumes, pumpkins, trick-or-treating and plenty of candy. Fan of horror films and everything scary? You’re in for a real treat with OLBG’s guide to the best Halloween slots.

Slot studios have jumped on the bandwagon with hundreds of slot games featuring horror-related themes. Like Christmas slots, they can be played all year round. With each scary slot highlighted below, you’ll find UKGC-licensed slot sites to play for real money.

Top 13 Halloween Slots

With hundreds of Halloween-inspired slot games, OLBG has done the hard work for you to come up with the best slots. Normally, we produce a top 10 list but as it’s Halloween, we’ve gone for 13 which relates to bad luck, death and horror.

Nolimit City is the undoubted king with many of our top 13 games produced by the controversial provider. Below, you’ll find details on each slot game, links to reviews with free demos (if available) and what real money casinos you can play them at.

1. Serial (Nolimit City)

Featuring the Bodycam Butcher serial killer who is thirsty for blood, Serial takes you to a gory crime scene: a bathroom with blood-stained shower curtains and blood-splattered walls. It’s as dark and sinister as you’re going to find. The heavy metal soundtrack adds to the disturbing visuals.

Beginning with 5 reels and 243 ways to win, wins award respins which open up Enhancer Cells. They award xWays for more ways to win, xNudge Wilds with an increasing multiplier, regular wilds and character symbols.

New Halloween Slots in 2024

With countess horror-themed games available, there are plenty of new Halloween slots that are released every year. All are not created equal with the 4 best new releases in 2024 highlighted below. They include slots from Print Studios, Big Time Gaming, Hacksaw Gaming and Pragmatic Play:

Dreadworks (Print Studios)

A sequel to Darkness and released on the 10^th of October 2024, Print Studios’ Dreadworks is set in Big Jack’s toy factory and is truly terrifying as you take on evil-intentioned toys. With the ability to change the lightness of the game, it’s played on 5 reels and 26 paylines from 10p a spin.

Features in SuperSpinners multipliers and Jack-in-the-Box Wilds which add their numbers to SuperSpinners as well as randomly add mystery symbols to the reels for more winning opportunities. In the Big Jack Bonus feature, a win with a low-value symbol will see extra free spins awarded as well as the symbol removed from play. Look out for Big Jack who can take over up to 5 reels where he’ll display a random symbol on each free spin.

Dreadworks is quite similar to the Darkness slot and has the same 20,000 x bet max wins. The RTP rate is 96.08% with the volatility in the very high category.

Boo (Big Time Gaming)

Released on the 26^th of September 2024, Big Time Gaming’s Boo slot has 4 reels, 4 rows and 256 paylines. Playable from just 10p per spin, you venture to a graveyard for spine-tingling thrills. With a tongue-in-cheek feel, wins lead to Reactions which see winning symbols replaced by ghost, wild or scatter symbols. Technicolour ghost Wilds appear on reels 2, 3 and 4 and can contain multipliers up to 4x.

In the Free Spins feature, you begin with 12 free spins. All 16 positions contain a persistent multiplier which can grow during the feature. When you win with ghost or wild symbols, 1 or more winning positions will see their multiplier increase up to 3x. The triggering scatters also begin with multipliers up to 4x. Scatters may land for extra free spins and a multiplier boost of up to 3x.

Boo may not be the most frightening listed on this guide to Halloween slots but it boasts a high 96.54% RTP rate and 47,050 x bet max wins.

Evil Eyes (Hacksaw Gaming)

Released by Hacksaw Gaming on the 12^th of September 2024, Evil Eyes has a dark horror feel and is set in an isolated graveyard. Overseen by ‘The Evil Eye’, it’s played on 5 reels and 3,125 ways to win from 10p per spin.

When the Evil Eye symbol appears under a winning symbol, the Evil Spread feature is activated. This sees the Evil Eye mark all winning symbols and rotate them right or down. This then is extended across the reels to replace marked symbols with the winning symbol. There is also free spins where low-value symbols that are spread by the Evil Spread feature are removed from play.

Evil Eyes offers a novel approach to existing mechanics for wins of up to 12,500 x bet. The RTP rate is decent at 96.24%.

Big Bass Halloween 2 (Pragmatic Play)

Released on the 21^st of October 2024, Big Bass Halloween 2 sees Pragmatic Play’s favourite fisherman swap his rod for a chainsaw. With 5 reels and 10 paylines, you can spin away from 10p per spin.

All about the Free Spins feature where you begin with up to 20 free spins, you’ll benefit from up to 5 modifiers which award extra free spins, more random features, extra Fisherman Wilds and Dead Fish Money symbols and starting on level 2. Land Fisherman Wilds with Dead Fish Money symbol to see the latter’s values collected. Collect Fisherman Wilds to progress through the levels for more free spins and a Dead Money Fish symbol multiplier up to 10x.

With a very high 96.71% RTP rate, Big Bass Halloween 2 comes with 5,000 x bet max wins. For reference, it’s the 19^th game in the Big Bass slots series.

Different Types of Halloween Slots

Halloween stretches much further than the 31^st 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.

• 👻 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).
