The Hallowe’en season has already been and gone for 2022, but that won’t stop Relax Gaming from serving up some spooky adventures via their new Horror Hotel online slot! This is a great-looking grid slot that awards a win for any cluster of five or more matching symbols appearing anywhere on the screen – no paylines or payways necessary. The game boasts a higher-than-average RTP of 96.17%, alongside a more than respectable top prize of 20,000x the bet.
The majority of new grid slots employ cascading wins in some manner, but Horror Hotel’s take on the popular mechanic is reasonably unusual and unique. Winning combinations will transform into mystery symbols, and it is all of the non-winning symbols which are removed from the grid. Each time that mystery symbols are created, the game will also award a free re-spin, potentially allowing you to spin many times without spending a penny – nice! Three or more bonus scatter symbols award a minimum of five free spins, which also come with a progressive multiplier feature. For those who wish to bypass the base game, a bonus buy facility is offered at 100x the current stake.
Are you feeling sad that it’s almost a year until the next Hallowe’en season? If so, don’t despair – our free demo slot of Horror Hotel should put a smile back on your face in no time!

Horror Hotel Slot Theme, Stakes, Pays & Symbols
We had a great mix of spooky slots in 2022, with lots of fresh ideas blended with classic concepts. The great thing about horror-themed games is that a wide range of different ideas can be used. Contrast this with the average pack of Christmas-themed games released each year, and you’ll see far more diversity in the “Hallowe’en-themed” slots. For example, let’s pick three games from our catalogue that fall into this category: Curse of the Werewolf, Beetlejuice Megaways, and The Twin Wins Mystery. These are all great fun slots that use wildly different imagery, yet they all fall into the category of spooky slots. The theme of Horror Hotel also hits a great sweet spot; it’s suitably dark yet doesn’t take itself too seriously. Overall, Relax deserves top marks for theme and presentation here.
There’s a huge spread of different payouts listed on the paytable due to the large playfield used in Horror Hotel. The top payouts are reserved for clusters of 35 or more symbols, but those will be extremely rare, considering that there are only 36 possible positions on the grid. Because of this, we’ll state the payouts for the maximum 35+ cluster as well as more reasonably sized hits of 15+ and 20+ matching symbols. Dracula makes an appearance as the highest-paying symbol here and has a return of 5,000x/100x/30x for the aforementioned cluster sizes. Frankenstein, Zombie, and the Werewolf all share the second-place spot with returns of 1,500x/50x/15x. The remainder of the paytable consists of three different coloured potions, all of which share identical payouts of 500x/20x/5x.
I was pleased to see a wide range of different wagers available in Horror Hotel, starting with a minimum bet of €0.10 per round and maxing out at a more than reasonable €50.00 per spin. So, regardless of the size of your balance, there will be a stake suitable for you if you to play at if you wish to do so.
Base Game & Modifiers
The base game of Horror Hotel takes place on a 6×6 playfield, and as this is a grid slot, there isn’t a need for any paylines or payways. Instead, winnings are paid whenever clusters of five or more matching symbols appear in adjacent positions. Prizes get progressively larger as the size of a winning cluster increases, ultimately reaching enormous sums such as 5,000x your stake for a cluster of 35 or more Dracula symbols.
Mystery Symbol
I’m sure you were wondering: how can I possibly hope to fill the entire grid with matching symbols? Aha, Relax has an answer for us here! Every time a winning combination lands on the reels, the symbols which form the win are transformed into mystery symbols. The remaining non-winning symbols are then removed from the screen, and a new set of symbols falls into view from the top.
Now, the game will award you a free re-spin before the mystery symbols again transform into a random symbol selected from the paytable. If the mystery symbols have any further matching symbols in adjacent positions, a new win is awarded before the entire process repeats.
This means that the mystery symbol cluster will progressively increase in size as long as one or more new adjacent symbols happen to fall next to it. If you are lucky, the whole thing could repeat enough times to form a single winning cluster of 35 or more matching symbols.
Horror Hotel Slot Bonus Features
The main bonus round is activated by hitting three or more bonus symbols on a single base game spin. The slot will award five free spins for this, with one additional spin added to the counter for each additional bonus symbol.
Free Spins
The free spins feature has several advantages over the base game. One wild symbol will be added to the playfield for each free spin you win, substantially improving your odds of hitting a large winning cluster. Those clusters are going to be worth much more to you than they would be normally too, as this mode also has a progressive multiplier feature that will increase by 1x before each mystery symbol transformation takes place.
Bonus Buy
If permitted within your jurisdiction, you can pay 100x the current stake to bypass the base game and go directly to the free spins. The number of free spins awarded is decided randomly, but this still seems like a fair price to me, considering the extra potential offered by the bonus round.
Horror Hotel Slot Review Final Thoughts
This is a well-presented slot with plenty of great features, but the huge potential for big wins sets this game apart from the crowd. I’ve been playing more grid slots than anything else recently, and I’ll definitely be adding Horror Hotel to my list of games to check out next time I play for real money.
