How the Game Plays

Castle of Terror takes players to a scenic village in Transylvania, where a looming gothic castle sets the stage for a vampire-themed encounter. The game utilizes a 6x4 grid with 4,096 ways to win, departing from the provider's signature Megaways engine in favor of a fixed-way system. Winning combinations are formed by landing three or more matching symbols on adjacent reels, starting from the leftmost side. The visual style shifts between a sunny, autumnal landscape in the base game and the dark, eerie interior of the castle during bonus rounds. High-paying symbols consist of four residents who reveal their supernatural nature when hit by the game's central mechanic.

Holy Water Feature Explained

The Holy Water mechanic can trigger randomly on any base game spin. When active, bottles of holy water are splashed onto two or more positions across the center four reels. If any of the four high-paying character symbols land in these "wet" positions, they transform into Wilds. Each such transformation also increments a global win multiplier for that specific spin by +1.

Free Spins and Enhanced Free Spins Explained

Landing three Silver Castle Scatters triggers 12 Free Spins, with an additional three spins awarded for every scatter beyond the third. During this round, the Holy Water feature is guaranteed to trigger on every single spin. Multipliers generated by transformations do not reset between spins and continue to grow throughout the session. If the multiplier reaches a multiple of 20, the game awards six extra spins.

If the trigger includes a Gold Castle Megascatter on the sixth reel, the Enhanced Free Spins are activated. In this version, the win multiplier starts at 2x and increases by +2 for every character symbol that transforms into a Wild, significantly boosting the payout potential compared to the standard bonus.

Win Exchange™ Feature

This slot includes a Win Exchange™ mechanic, allowing for alternative ways to enter the bonus round. Any win of 100x the stake or more can be exchanged directly for 12 Free Spins. For wins between 25x and 100x the stake, there is an option to gamble the entire win on a segmented wheel for a chance to win the 12-spin bonus.
