When it comes to performance, the game offers a 96.72% RTP in standard mode and 96.73% RTP when playing with Enhanced Free Spins.

One of the most thrilling features in the Castle of Terror slot is the Holy Water Wilds mechanic. On any base game spin, a splash of holy water can spread across the reels, instantly transforming nearby villager symbols into vampire wilds. This sudden shift can dramatically boost your chances of landing a winning combination, adding a layer of suspense to every spin. It’s not just a visual treat — it’s a powerful win-triggering moment that keeps players on edge.

Free Spins & Enhanced Free Spins – Multipliers that Keep Growing

Triggering the Free Spins feature requires landing 3 or more scatter symbols, launching you into a bonus round where the excitement truly ramps up. You’ll start with an unlimited win multiplier, which increases by +1 each time a vampire symbol appears. For even more adrenaline, the Enhanced Free Spins round — activated by the golden scatter — pushes the multiplier up faster, creating the potential for massive payouts. This is where high volatility meets high reward.

Megaways™ Mechanics – 117,649 Ways to Win

Set against the backdrop of a creepy castle under a blood-red sky, Castle of Terror blends sinister charm with a polished, atmospheric design. The reels are filled with vampire lords, elegant ladies, and spooky villagers, while the chilling soundtrack builds suspense with every spin.
