Horror Hotel - Slot Overview
Horror Hotel is more of a parody horror release than a serious attempt at being spooky, with lively animations and enjoyable visuals from start to finish. It plays out on a 6x6 grid with cluster wins, set in a graveyard with a mysterious castle dimly lit by the full moon. The base game revolves around the Mystery symbols feature, while the bonus round moves you into the castle reception. The game is capable of dishing out hefty cluster hits and caps out at a 20,000x max win.
Horror Hotel Symbols and Paytable
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 higher paying set features a mummy, a werewolf, Frankenstein and Count Dracula, with the top symbol reaching 5,000x for 35+. The lower paying group is potion bottles in red, green and blue, which can reach 500x for 35+. The Wild symbol steps in for pay symbols to help complete or improve cluster wins.
Cluster wins require 5 or more matching symbols connected horizontally or vertically. Non-winning symbols can be removed via the cascading-style process that ties into the Mystery Symbol feature. You’ll also see a skull Scatter that triggers free spins when 3 or more land. With the mix of premium monsters and colourful potions, the paytable feels balanced for a grid slot that can deliver up to 5,000x from a single cluster and stretch further via features.

Horror Hotel Slot Features
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, and it’s the heartbeat of the base game.
The Cascading mechanic plays out differently than usual because the win first converts into mystery, then the board is cleared of non-winners before the respin. I rate this loop highly, as it builds clusters in a tidy way and can chain several reveals. Wilds aren’t required to start the feature, which speeds things up compared to older riffs on the idea. When it clicks, you can grow a decent cluster and line up those bigger symbol choices off the reveal.
Free Spins in Horror Hotel
The Bonus Round triggers from 3 scatters in view, awarding 5 free spins, and you get +1 additional spin per extra triggering scatter. During the feature, scatters also award +1 extra spin. You’re guaranteed one wild on the first spin, and an additional wild is added per spin that follows. The Mystery Symbol feature remains active, and the win multiplier increases by +1 per cluster win and never resets as long as the feature lasts, which can turn modest boards into tidy returns.
Horror Hotel RTP, Volatility and Bonus Buy
RTP sits at 96.17% with high volatility, on stakes from 0.10 to 50 per spin. The grid format can serve a big hit from the base via mystery loops, and you can still win up to 5,000x from a single cluster, while the overall cap lands at 20,000x your stake. I found the free spins can be short-lived at times with only 5 to start, but the progressive multiplier and growing wild count make extra spins more valuable than usual.
Non-UK players, and anyone in an eligible jurisdiction, can use the Bonus Buy feature at 100x your stake, which guarantees at least 3 scatters and nudges the RTP to 96.5%. It’s a clean way to sample the reception-side action quickly, though the option is not for UK players. If you prefer the organic route, the base game’s mystery-respin loops do a fair job of pacing the balance and feeding bonuses without feeling too grindy.
Review Summary for Horror Hotel
Relax Gaming could’ve released a pure reskin of their 2021 Xmas release, but they’ve built on the original concept in smart ways. In Horror Hotel you don’t need a wild included in the cluster win to trigger the mystery symbol feature, and while symbol values have taken a hit to compensate, the ceiling is still tasty. You can still win up to 5,000x from a single cluster, and the neat respin loop gives the base solid texture.
You still risk getting only 5 free spins, and the bonus can fizzle, yet the mystery symbol respins and increasing amount of wilds help generate clusters. Extra spins land with better upside thanks to the progressive multiplier that never resets in the round. Pros: winning symbols turn mystery for respin; FS with increasing wilds and a progressive multiplier; max win of 20,000x your stake. Con: 100x Bonus Buy not for UK players. Overall, a superior release.
