Unearth Monstrous Wins in Slotland’s New Castle of Horror Slot

The 27th Anniversary party continues with a week of creepy fun and bone-chilling BOO-nuses

Slotland invites online casino players to step into the Castle of Horror — if you dare. Just in time for the spooky season, the new Castle of Horror slot game throws open its creaky gates and is treating players to a Halloween bonus feast. New and existing players can grab a 105% Match BOOnus and Free Chips.

Shadows crawl across the 6x3 reels in this dark, cartoon-horror adventure. Spin across 13 fixed paylines and encounter a sinister cast of characters, including a Dracula-like vampire with glowing eyes, a snarling werewolf, unnerving pumpkin-spiders, vials with a floating eyeball, and monster jaws full of sharp teeth. The neon-glowing, spooky aesthetic sets the perfect Halloween mood, where a 6x Wild can deliver 2,000x your bet.

“What better way to mark 27 years of entertaining our players than by inviting them into a haunted castle?” said Michael Hilary, Slotland Manager. “This has been a landmark birthday for us, and we wanted to give our players a gift. The Castle of Horror is the perfect blend of spooky fun and big win potential, and it encapsulates the innovative spirit that has kept us at the forefront for nearly three decades.”

The castle’s true terror and treasure lie in its trio of bonus features. Scatter symbols pay instantly, with 1 to 6 scatters awarding up to 10x your total bet. Land 3 or more Free Spins scatters to trigger the Freakish Free Spins round with 3-12 spins, featuring Colossal Wilds and extra spins for additional scatters. For instant rewards, trigger the Pick Me Bonus with 3 or more scatters to level up through the castle's depths, unlocking increasingly valuable coin prizes from up to five rows.

Join Slotland’s birthday bash and Halloween festivities. The terror doesn't stop there! Slotland's sister site, Winaday Casino, has also unleashed the Castle of Horror, offering another venue to hunt for its eerie bounty!
