How the Game Plays

Horror Hotel by Relax Gaming takes place on a 6x6 grid set against a moonlit Transylvanian graveyard and a spooky manor. This slot utilizes a Cluster Pays mechanic where winning combinations are formed by landing five or more matching symbols vertically or horizontally adjacent to one another. Lower-value symbols are depicted as colorful potion bottles, while high-value symbols feature classic monster archetypes: a Mummy, a Werewolf, Frankenstein’s Monster, and Count Dracula himself. Every winning cluster triggers a unique cascade where the winning symbols transform into Mystery symbols and sink to the bottom of the grid, followed by a respin of all other positions to potentially increase the cluster or form new ones.

Free Spins Explained

The Free Spins feature is activated by landing three or more Bonus symbols during a single game round, awarding five initial spins. Every additional Bonus symbol beyond the third grants one extra spin. During this round, a progressive win multiplier is introduced, increasing by +1 every time a Mystery symbol reveal occurs. Additionally, the game guarantees at least one Wild symbol on the first spin, with the number of guaranteed Wilds increasing by one on every subsequent free spin.

Mystery Symbol & Respin Feature

The core of the base game is the Mystery Symbol mechanic. When a win occurs, those symbols turn into "Question Mark" tiles and lock in place while the rest of the grid clears for a respin. If new symbols match the existing cluster or form a new winning cluster, those also turn into Mystery symbols and trigger further respins. Once no more wins are formed, all Mystery symbols reveal the same randomly chosen paying symbol for a final payout calculation.
