A young girl finds a jewellery box and unwittingly releases the evil trapped inside. This bone-chilling horror is a Halloween favourite for a couple of reasons. Halloween Jack is complete with terrifying images and a score straight out of a Hollywood horror film, setting a scene where you expect the monster to crawl out of your screen.

This 5 x 3 slot game makes for brilliant entertainment if you can handle witches, hell-hounds and deadly curses. Although its nightmarish details may scare you, bonus features like Free Spins, Walking Wilds and the Jack’o’Lector Bonus round present more than enough reasons to endure the frights.

Sinister music and scenes of an abandoned asylum with walking-dead nurses are usually signed to run! With this Gamomat production and the chance to win 5,000 times your stake, it’s the opposite. Sure, you will have to endure the sounds of blood-curdling screams and running into angels of mercy, but that is the cost of a good scare, right?

Book of Madness online slot has a blood-dripping Bonus game with 10 Free Spins if you land 3 Books in a round. The 10 flexible paylines have werewolves, blood iv bags, and haunting images. Its Expanding Bonus Symbol and Gamble Features present hellishly good entertainment.

Ancient Egypt calls from a cracked open tomb and the ghost is ready to take revenge. The slot grid hovers in between pillars and eternal fires burning, and the eerie glow from behind the reels is a hint that something is looming.

Ghost Spins activate at random, where the evil spirit jumps out at you with his piercing eyes and hands. The Canopus Scatter doubles up as the Wild and 5-oak will pay up 2000 coins. Enjoy the thrill of expanding symbols, Free Spins and the chance to win 10,000 x your stake.

Potions, cute critters, and a friendly witch will entertain you in this Progressive Jackpot Network title, presenting the possibility of a mega jackpot win of at least €1 million.

A youthful, pretty witch is the Scatter symbol and triplets will activate 15 Free Spins with a multiplier. The jackpot Bonus Feature will trigger at random where you spin the stone wheel for a chance at the fortune.
