Hills Sanatorium and 7 Other Monster Slots You Need to Play Online

There are many great slot machine themes to enjoy at the top online casinos. Whether you’re a fan of fantasies, holidays, classic slots, or any other genre, you’ll have no trouble finding one you enjoy.

One of the best slot themes has to do with those nasty creatures we call monsters.

I’ll be going over my top eight monster slots, which can all be found at safe online casinos. These monster slot machines all bring something unique to the table.

If you’re looking for the best online slots to play, you can’t go wrong with any from my list below!

Monster slots don’t always need to be scary. But in the case of Hills Sanatorium, you can forget about any laughs.

This is a game designed to put the willies up any scaredy cat chasing wins.

The characters are all very familiar. There is the obligatory scary nun (those of us who went to a Catholic school should be immune) and a collection of masked freaks just waiting for their opportunity to pounce.

This medium volatility slot will have you looking over your shoulder when played in the dark. Until you hit those sweet free spins, of course.

You might find the bonus game mighty scary but more than palatable if you land some big wins. Speaking of wins, if you want more ways to win real money then you should consider playing these Drake Casino slots.

Is the best monster slot online that has been released in the past couple of years? Try it for yourself by visiting Drake Casino.

Can you lump dragons in with monster themed slot machines? Why yes. I just did.

Despite how you might classify these mythological beats, they do, objectively, fall under the category of monsters. And no. I don’t care about your Welsh flag, nor how many episodes of “Lord of the Thrones” you watched with your partner.

The game is pretty neat. It’s bordering on the high-volatile side, with some big wins possible. It’s also rated highly on the list of best dragon slots.

Again, not all slots with monsters require you to prepare for a pant-pooping extravaganza every time you spin the reels.

This one might not be the most terrifying game out there, but try it at DuckyLuck Casino to see how many colossal wins you can bank.

Having played this one recently, I was keen to bring it to the attention of you, good folks.

If you’re wondering when we’ll get back to the scary monster slots, you might be missing a very crucial element that we have in almost every single horror movie: suspense. With that said, goblins are scary, too, right?

If you think I would just throw any monster themed slot machines your way, think again. There is a method to my madness, for sure. Especially when said lunacy can be backed up with reasons to play a particular game.

Aside from the stellar graphics and cool background sounds, you can get a shot at some of the following.

El Royale Casino is where you will find this game. Give it a spin today, and feel free to let me know how you get on in the comments section below.

Ancient Gods might not sound like it has much to do with monsters. At least not to the initiated.

But it’s evident that this game, considered to be an entry for the best monster slot online by yours truly, is not exactly best reflected by its title.

The various beasts you will encounter on your quest for glory are all tempestuously inhumane in their own special ways.

Take, for example, the pissed-looking dragon. Or the weird dinosaur-turtle-dog thingy. Something that reminds me of a more incensed version of a character from my little sister’s favorite show back in the day, Pokémon.

This is one of the slots with a monster theme that will grab by the neck and drag you, elbows deep, into a session that could last a while.

You can read our review of Las Atlantis to become more familiarized with the site, or if you’re after some more traditionally terrifying slots, feel free to keep reading.

The truth is, you’ll come across all kinds of monster casino slots.

But when partaking in a little online gambling in the US, it pays to play a reputable casino. Every single one recommended in this piece is just that, including BetUS.

It’s quite fitting to recommend this slot after discussing the importance of playing at safe sites. You can experience your own Jekyll and Hyde moment by playing at sketchy casinos: things might look great at first, only for a radical change to come out of nowhere.

In this game, based on a story by Robert Louis Stevenson, the duality of good and evil is underlined. But we’re not here for existential allegories, are we? It’s slots with scary monsters we want!

The Dr. Jekyll and Mr. Hyde slot machine is right up our alley. I’m also willing to bet that you’ll find horror slots appealing if this one is at the top of your list.

This slot machine has plenty of rewarding features, such as the following:

• Expanding Wilds
• Free Spins
• Police Badge Sticky Spreading Wilds
• Jekyll’s Potion Expanding Sticky Wild

Check out this BetUS review to get a taste of the site and its offerings. You can expect a creepy slot with an air of gothic unease, much similar to Stevenson’s iconic tale but with bonuses.

Screw the monster slot games, they said. Where are all the best vampire slots online, they said?

Here is one that will appeal to fans of both, is my reply. So, keep it down at the back, and I’ll explain why.

Nobody disputes that vampires are monsters. They vary in terms of fearsomeness, of course.

I mean, I don’t think Gary Oldman’s Dracula would lose in a fight with Count Cashtacular. But he would arguably be stingier if you’re looking for a dig-out.

He never drinks wine, either.

I still rate Count Cashtacular up there with the best scary monster casino slots you can play. Some might find his general profligacy to be terrifying, while others might just be creeped out by his gnashers.

It doesn’t exactly have a creepy Skinwalker Ranch feel to it, but don’t let that deter you from going to Red Dog Casino and trying it out.

There are monster slot machines. And monster slot machines, right?

Ever since we put together our in-depth review of Zombie FC, this game has become one of the most popular in the genre.

I think it’s a fantastically innovative take on the undead theme, with horrifically mutilated soccer stars a pretty fresh take.

You can bag up to 50x multipliers as well as an in-game jackpot. All set against one of the more unsettling backgrounds of any slot you will ever play.

There are a lot of great zombie slots to play online, but this is easily one of the best. Head on over to Ignition Casino and find out what the story is!

Bloodlines is the last entry on my list of the top monster slots to play online.

This is a relatively new addition to Bovada’s casino catalog. Although it hints at royalty, the game is based on one of the more popular areas of monster themed slots: vampires.

Although scarier than Count Cashtacular, the games aren’t a million miles removed from each other in terms of quality. You can get your hands on re-triggerable bonuses, which is also a good thing to keep in mind.

3 scatters or more trigger the free spins. The Bloodlines logo acts as the special symbol required to enter that bonus game. But there are also Bloody Wilds and an awesome Mansion feature that can help you suck the casino dry.

Well, we all hope to do that, right? Be sure to play Bloodlines at Bovada, as well as the best Halloween slots online in order to prepare for the spooky season.

Still haven’t found a game that you want to try yet? Not to worry, there are plenty of slots with monsters across the top casinos. I’ve provided you with a few more great games that you should consider playing.

The first of which is Freaky Frankenstein, which has an RTP of 96.83%. This slot machine is a bit older than most (2017 release date), but it has been able to stay relevant for a good reason. To no one’s surprise, this game is also one of the best Frankenstein slots.

Are you a Bigfoot believer? If so, you should head over to SlotsandCasino to play Bigfoot Mountain. This slot machine has five reels, four rows, and 75 paylines. It has a low volatility rating, but the progressive jackpot gives this slot a lot of upside.

The Godzilla vs. King Kong movie had a strong audience score of 91%. Since a good amount of people enjoyed the film, there’s a chance that this could be their next favorite slot machine.

You can find it at Wild Casino, which offers a 250% welcome bonus (up to $5,000).

That’s going to wrap up my list of monster slot games. As you can tell, there are several great monster slots that you can find at the top online casinos.

You might even feel like you have too many to choose from.

If you’re still struggling to decide on which of these monster slot games you should play, I’ll help point you in the right direction.

To be clear, there is no wrong answer here. That’s because it all comes down to personal preference. I could declare Hills Sanatorium as the winner, but you might not be that interested in it.

Are you most interested in a slot that has a high RTP? In that case, Dr. Jekyll and Mr. Hyde has an RTP of 96.04%, the highest out of these monster slot machines.

If you prefer to play a slot machine that offers free games, I recommend Hills Sanatorium, Goblins: Gluttony of Gems, Dr. Jekyll and Mr. Hyde, or Bloodlines.

Jackpot enthusiasts should make their way to Zombie FC.

As I said, there is no wrong answer here. Play at whichever slot machine or online casino you gravitate to the most. If you’re looking for more related slot machines, I recommend these witch slots.

5 Best Witch Slots to Play Online
