How to play Horror Hotel mobile slot

The Horror Hotel slot invites you to the colourful graveyard where symbols pay in clusters and leave behind mystery symbols filled with respins.

Relax Gaming studios keep surprising us with volatile and fun games, from Net Gains slot to the Dead Riders Trail review, and we were expecting big things here. Instead, we got something small but in the best way.

The Horror Hotel mobile slot is a 6×6 grid slot where every win will turn into sticky mystery symbols for one free re-spins, allowing you to build up a series of wins that could see you walk away with 20,000x your bet.

It’s no easy feat. Horror Hotel has a low RTP of 94% to make up for its huge top win, not unlike real money slots like the True Grit Redemption slot, for example.

The best advice we can give you here is to bet low and build up slowly as you wait to hit the free spins, where you get progressively bigger multipliers and wild symbols.

A high-variance Halloween slot

The good news is that there’s not a whole load of symbols in this Horror Hotel slot online. The high-paying symbols include Dracula, Frankenstein, the Wolfman, and the Mummy, followed by just three low-paying ones: a red, green, and blue magical potion.

That’s a good thing, mainly because it means you get lots of little wins all the time – unusual for a high-variance machine. But the re-spin feature and your enjoyment of the game depend on getting wins.

Why? Because every Horror Hotel slot win is a sticky win, only instead of keeping the same symbol, the symbols change re-spin after re-spin and drop down the reels.

It allows for surprises, as you can start with a low-paying symbol, but on the next re-spin, it could be a screen full of Dracula popping up to surprise you.

Why the Horror Hotel slot review is only 4 stars

We were so tempted to give this Horror Hotel online slot review a glowing 5 stars, mostly because we had so much fun.

But to get anywhere near the top win of 20,000x your bet, you’ll have to hit 5 scatters and play a minimum of 7 free spins with increasing wilds and multipliers.

That’s the most exciting part – the Horror Hotel bonus games. Because on each spin, the multiplier increases by 1, and the number of wild symbols increases by 1. So by the fifth spin, you have a 5x multiplier and 5 wild symbols.

Getting the top win would be like staking Dracula, burning up Frankenstein’s monster and unravelling the Mummy simultaneously. A long shot. So once you get anywhere near 1,000x your bet, you might consider heading to another of the Relax Gaming slots.

We know you’ll be back to this Horror Hotel grid slot soon enough.

Bonus Features

Cluster Pays: Whenever 5 or more symbols touch horizontally or vertically, you'll get a cluster and a win.

Wild: the W is the wild symbol and substitutes for all symbols except the bonus symbols.

Mystery Symbol Feature: This activates on every win. The winning cluster will stay on screen, drop to the bottom of the reels, and receive a re-spin. These turn into mystery symbols and will always show one paytable symbol - meaning you are guaranteed to get at least 2 wins in a row.

However, the feature continues if you manage to capture any new symbols within the cluster or get another win. So all winning symbols turn to mystery symbols, drop at the bottom of the reel and will all show one symbol.

Free Spins: Get 3 or more ghost scatter symbols, and you'll trigger 5 free spins. Any additional scatter gives you +1 spins to your total.

During the bonus, an increasing number of wilds will land - starting with one on the first, two on the second, and so on.

You also get progressive multipliers that increase on +1x on each spin - again, you get a 1x multiplier on the first spin and a 5x multiplier on the fifth spin.

Buy Bonus: for 102x your bet, you can buy entry straight into the free spins. The RTP of the game increases to 94.61% instead of the normal Horror Hotel slot RTP of 94%.

Horror Hotel Review Conclusion

We had a good time playing this Horror Hotel slot game, despite having a low RTP of 94%. But then again, it has a high top win of 20,000x your bet, so we can almost forgive Relax Gaming.

Despite the cutesy Halloween slot theme, this game is not for the faint of heart.

There are monster wins, and you'll need monstrous patience to hit the free spins and multipliers to get to those wins.

This is no Money Train 3 slot, but if you are a fan of the crazy volatile Relax Gaming slot machines, you should add this to your playlist when you next go to your favourite online casinos.
