Horror Hotel Review

This is more of a parody horror release than a serious attempt at being spooky, and you get lively animations and enjoyable visuals in all stages of the game. Horror Hotel plays out on a 6x6 grid with cluster wins, and the game is capable of dishing out 5,000x from a single cluster win. The grid is placed in a graveyard with a mysterious castle in the backdrop, and the uncanny scenery is dimly lit by the full moon.

You’re taken into the reception of the castle in the bonus round, and the base game revolves around the Mystery symbols feature. Winning symbols turn into mystery symbols for a respin, and this repeats if the win is improved or a new win is created. You get a progressive multiplier in the bonus round, as well as an increasing amount of guaranteed wilds. The 20,000x max win is solid, and fans of Santa’s Stack will probably love what Relax has done with the concept in this release.

Horror Hotel Slot Features

The symbols pay between 500 and 5,000 x your stake for 35+ in a cluster, and between 0.1 and 1 x your stake for the minimum of 5 matching symbols in a cluster. The Wild symbol steps in for pay symbols to help complete or improve cluster wins, and non-winning symbols are removed via the Cascading mechanic. The Cascading feature plays out differently than usual in more than one way, however.

All winning symbols, including wilds, are turned into Mystery symbols. You then get a respin as all non-winning symbols are removed, and the mystery symbols drop to the bottom of the grid before the new batch of symbols drop. After the drop, all mystery symbols turn into a randomly chosen matching symbol. This process repeats if the original cluster win is improved, or a new winning cluster is created.

The Bonus Round triggers from 3 scatters in view, and this gives you 5 free spins. You get +1 additional free spin on top of that per additional triggering scatter, and scatters also award +1 extra spin during the feature. You’re guaranteed one wild on the first spin, and an additional wild is added per spin that follows. The win multiplier increases by +1 per cluster win, and it never resets as long as the feature lasts.

On a final note, non-UK players, and anyone living in an eligible jurisdiction, can take advantage of the Bonus Buy feature. This will set you back 100x your stake, and you are then guaranteed to land at least 3 triggering scatters on the spin that follows. The RTP increases to 96.5 % when you purchase the bonus round.

Review Summary

Relax Gaming could’ve easily released a pure reskin of their 2021 Xmas release, Santa’s Stack, but they have instead taken the time and effort to build on the original concept. In Horror Hotel you don’t need a wild included in the cluster win to trigger the mystery symbol feature, but the symbol values have taken a hit to compensate. You can still win up to 5,000x from a single cluster though, so it’s hard to complain too much about that.

You still risk getting only 5 free spins, however, and the feature can be short-lived many times. It’s prolonged by the mystery symbol respins, however, and the increasing amount of wilds will help generate cluster wins. This makes getting extra spins more lucrative than usual, and you can still win up to 20,000x your stake. Overall, Horror Hotel is a superior release, even without the adorable 8-bit pixel visuals you get in Santa’s Stack.
