Halloween is just around the corner, and what better way to get into the spooky spirit than by playing some Halloween-themed slots? Whether you’re a fan of ghosts, witches, or vampires, there are plenty of online slots in the UK to satisfy your love for all things Halloween.

Serial

Launch: November 2022

RTP percentage: 94.08%

Bonus/Jackpot: Yes, there is a bonus game and the possibility for a jackpot win.

Serial is a spooky slot game that immerses players in a world of suspense and horror. At its core, Serial explores the macabre fascination with serial killers, bringing it to your screens in a thrilling slot format.

The game’s sinister aesthetics and unsettling sound effects truly encapsulate the Halloween spirit, with symbols such as skulls, candles, and bats. The popular bonus round and potential for huge jackpots provide the perfect incentive for players.

One of the key reasons to play Serial is its unique ‘Murder Spins’ feature, where players are offered the chance to win big by successfully completing a set of murder scenarios. If you’re looking for a darker, more adult-themed Halloween slot, then Serial by Nolimit City is the perfect pick.

Book of Halloween

Launch: October 2019

RTP percentage: 96.23%

Bonus/Jackpot: Yes, free spins and expanding symbols.

Book of Halloween — inspired by the well-known slot game Book of Ra — has managed to carve its niche in the realm of Halloween-themed slot machines with Tim Burton-esque visuals and soundtrack. The background art creates a feeling of foreboding, with its gnarled and twisted cartoon trees, and a lone house on a hill.

As a creation of Inspired Gaming, the slot game extends over 5×3 reels and 10 paylines, adhering to the standard “Book of…” format. The spectral symbols include a skeleton hand, a bubbling cauldron, a gravestone, and a pumpkin-headed character.

The gameplay revolves around a unique wild/scatter symbol, the Book of Halloween. This not only triggers the standard “Book of…” feature (10 free spins with expanding symbols) but it also sets in motion the “Spin Chance”, a feature that allows players with low credit to earn an extra spin.

This game is for players who crave a classic Halloween slot experience with an added dose of excitement.

Million Dracula

Launch: October 2020

RTP percentage: 95.3%

Bonus/Jackpot: Yes, jackpot and random wilds.

Red Rake’s Million Dracula is a newer addition to games with the Halloween slot theme, making its debut in October 2020. Drawing inspiration from Bram Stoker’s iconic 1897 novel, the game is centred around Count Dracula, the archetypal blood-sucking vampire.

The slot has a distinctive gothic aesthetic, with a dungeon-like backdrop of grey brick and metal grates that create a cold and mysterious atmosphere. The subtle, eerie sounds that ring out during gameplay, punctuated by lightning cracks, scurrying rats, and horror-film screeches, add to the chilling theme. However, despite the dark and slightly obscure visual setting, players will find plenty of exciting features to keep them engaged.

One of the game’s highlight features is the free spins bonus round, which comes with a unique twist. Players can trigger eight, 12, or even 16 free spins by landing three, four, or five-plus bonus symbols, respectively. During this round, players initially start with four rows, with new rows revealed two at a time after each win. The feature is played on special reels, devoid of bonus symbols. If the total win at the end of the feature is less than 10x the bet, four additional spins are triggered.

The maximum win in this feature is a whopping 10,000x the bet that was in play when the round was first triggered. This, coupled with the chance to win a progressive jackpot, makes Million Dracula an enthralling choice for players seeking big payouts.

Sinister Circus

Launch: August 2019

RTP percentage: 96%

Bonus/Jackpot: Yes, free spins and wilds.

Take a trip to a supernatural carnival with 1X2 Gaming’s Sinister Circus.?

The game is set against a creepy circus backdrop, with glowing symbols of hearts, diamonds, clubs, and spades. Prepare to be dazzled by reels of animal performers, a fortune teller, and the top-paying creepy magician.?

Sinister Circus doesn’t skimp on bonus features; the snap of a ringmaster’s whip and the sudden apparition of a deranged clown usher in regular and expanding wilds. Throwing knives act as scatters, triggering a free spins mode where sticky wilds come into play. Based on the number of scatters you land, you can enjoy as many as 15 free spins.

The visuals, coupled with the delightfully macabre music, amplify the game’s spooky undertone. But it’s the high RTP percentage and the potential of winning 1,500x your stake that makes this game a gripping choice for online trick-or-treaters.

Mega Moolah: The Witch’s Moon

Launch:? October 2016

RTP percentage: 88.12%

Bonus/Jackpot: Yes, Mega Moolah progressive jackpot and multipliers.

The Witch’s Moon slot, a part of the adored Mega Moolah series, is set in the enchanted lair of a witch on a moonlit night. Players will find themselves mesmerised by this mystical game with its five reels, three rows, and 25 paylines.

This online slot’s design is simple yet compelling — from the colourful, cartoon-style backdrop to the wooden-like reels displaying symbols ranging from ace to 10, royals to a broom, dripping candles, a bubbling cauldron, a green frog, and a book of spells.?

Mega Moolah: The Witch’s Moon RTP is 88.12%, which is somewhat low for a progressive jackpot slot, but the frequency hit rate of 46.36% means that players can expect to land a winning combination on almost every second or third spin.?

This bewitching slot game offers several bonus features, including multiplier wilds and free spins. The Double Wild feature can double the payout when a wild is part of the winning combination in the base game. But the real highlight of playing online slots such as Mega Moolah: The Witch’s Moon is undoubtedly the chance to hit record-breaking progressive jackpots.
