This Halloween casino list is based on our perfectly timed research, which focused primarily on the Halloween slots they offer, and the promotions that can make a difference. This includes, but is not limited to free spins bonus offers, online casino promotions that feature Halloween slot machines, and various raffles, competitions, and a few tournaments. Check them out! However, before you get your expectations high, make sure that you can join the casino!

Top Halloween Online Slots

Halloween slots are distinct, but they, as a group, have quite a few things in common. In general, they all follow some scary, spooky theme, that perfectly fits the whole Halloween festivities. Needless to say, these Halloween slots still follow the basic slot rules.

You still get to win more if you see a lot of Wild symbols on the reels, and you still get to trigger free spins/bonus rounds, or bonus games, which can be extremely rewarding. The hit rate, however, is still within the respective software provider's average. Do not expect a higher hit rate, more frequent bonus games, or common free spins triggers.

The pumpkins, or better said, the Jack’O’Lanters, the ghosts and the “casual” vampire are still part of the paytable. It’s basically how we identify Halloween online slots. That, and we also consider whether they are featured in casino promotions and are promoted during and before Halloween.

By far the most popular Halloween slot in the United Kingdom, it’s Halloween Fortune! Produced by Playtech, and promoted by all Playtech online casinos, the Halloween Fortune slot has a lot to offer. Compared to what the other video slots on this list have to offer, it features the simplest, yet one of the best-designed slot machine features. All symbols you will see on the reels fit the Halloween festivities and the holiday mood. Spooky candle holders that are in fact skulls, cackling witches, weird talismans, and the usual witch's pet, a dark, scary cat. Then again, it wouldn't be a Halloween slot without a Jack’O’Lanter, which in this Halloween game it’s the Wild symbol.

However, you should be more excited about the Bonus symbol, which is, in fact, a boiling cauldron, most likely with the witch's magical potion.

Witches’ Brew Bonus

Should you trigger the bonus game, you will get the privilege to work closely with the witch. You will help her create her magical potion. In practice, you need to select one of the 3 witches, which will determine your free games. Then, you're supposed to choose one of the six options on the screen, which is in fact, your multiplier for the duration of the free spins.

Most importantly, if you land a bonus symbol anywhere on the reels, during free spins, you will win a random amount of additional free spins. However, bear in mind, you can win up to 20 free games in total! It pays well to do the witch’s bidding!

Lastly, the multiplier we mentioned, it can go as high as 10 times!

Lucky Witch (Microgaming)

lucky witch slot by microgaming

Lucky witch is one of Microgaming’s biggest holiday-themed slots, showcasing all the Halloween elements you can think of. The vibe is not as weird as in Paranormal Activity by iSoftBet, but it still is enough to give you that much needed Halloween feel. Microgaming was pushing the limits with their bonus games in the past, and this is probably the best relic of that era. Although all elements are in line with the Halloween customs, you can still quite easily recognise the special symbols while spinning the reels of Lucky Witch slot.

There are two general bonus features which you want triggering as frequently as possible! We prefer the second option.

Free Spins Bonus

The free spins bonus is a simple, free spins feature which can bring you up to 13 free bonus rounds per trigger. Regardless of the number of scatters on screen, you will always get 13 free spins. Besides the free rounds, you will also get the scatter wins added to your payline wins.

Mystery Bonus

Now, this is the real deal! The Mystery Bonus symbol appears only on reels 1, 3 and 5, and should this happen; you will get a Mystery Bonus Game.

  • Magic Potion Bonus – You are supposed to pick from 12 different bottles on screen, and if you are lucky, you will reveal as more. More revealed prizes mean more cash prizes. Revealing the WIN ALL symbol brings you all prizes you could get in this bonus game. However, if you reveal the SKULL symbol, the bonus game is over.
  • Pumpkin Bonus – Conveniently, a Pumpkin bonus is the 2nd bonus game on the menu. Again, you are supposed to choose from several different options, in this case, 3, and you have two chances to change your mind, and pursue a bigger prize. How do you do this? You click YES if you are happy with the prize, or you select NO if you're aiming for a higher prize.
  • Secret Vault Bonus – Tricky, tricky, and it can get even trickier. The Secret Vault bonus game is probably one of the games that’s’ most teasing. First, you select 3 symbols, which are not revealed, but the rest of them are! Then, once all other symbols are shown, you are supposed to choose one of the three symbols you selected in the first place. It's a roller coaster!
  • Spell Book Bonus – Again, another pick and click bonus game. This time around, you are choosing between 3 different books, and each of them comes with a random multiplier. However, that's just the basic multiplier! A magic imp can appear on the screen, casting a spell and granting you a multiplier up to 52x!
  • Two Wild Symbols – We felt like we should make it clear. There are two different Wild symbols. One of them, the Lucky Witch text symbol is available in the base game, whereas during Free Spins, the Wild symbol is the Lucky Witch herself. Moreover, she not only substitutes for any other symbol, but she also doubles any wins that she's a part of. Note, she substitutes only for a few high paying symbols only!

Bloodsuckers (NetEnt)

blood suckers slot screenshot

Blood Suckers is one of NetEnt’s "rolling" legends because, after so many years, it still has a loyal "following" so to speak. Year after year, it has always been at the top of most slot lists.

Conveniently, it's one of the highest RTP slots - with a return rate of 98%. Unlike the Lucky Witch by Play’n Go, Blood Suckers comes with more straightforward bonus features. There's the standard Wild symbol, the free spins, and the distinct bonus game.

Blood Suckers Free Spins

That horrifying vampire bride, you want to see more of her. To be precise, you want to see at least 3 of them on the screen. Regardless of the number of Scatter symbols on the reels, you can win up to 10 free bonus rounds. However, more scatters still means a higher cash prize, equal to the bet times the multiplier, up to 100x. Additionally, any free spins wins are tripled!

Blood Suckers Bonus Game

The bonus game sure fits the name of the slot! Like any vampire movie, there's a vampire hunter, and in this case, that's you. 3 bonus symbols, in succession from the leftmost reel to the right, triggers the bonus game. You are taken to what looks like a "vampire lair". You will have to open the coffins by clicking on them. Opening an empty coffin ends the game.

Happy Halloween (Play’n Go)

happy halloween slot by play n' go

It doesn’t get “more Halloween than this”! Happy Halloween is produced by Play’n Go, and it’s a real treat! There are no card like symbols, meaning all of them showcase some Halloween element, be that a witch, a Jack’O’Lantern, a ghost, a mummy, and there's even a Frankenstein-like character. However, we can't say that it's THE Frankenstein, more like a random reanimated guy. This is for sure one of the Play n' Go best slots

Happy Halloween Free Spins

To trigger the Happy Halloween Bonus Free Spins, you need to get at least 3 scatter symbols on the reels. They pay 4x the total bet, and they also activate the much-desired free spins game. However, that’s not all! You also get 2 STACKED WILD symbols on reels 2, 3, 4 or 5 during every free spin. Believe it or not, we’re not done.

So, the base free spins game comes with 10 bonus rounds, but you can re-trigger the feature, and you can win up to 20 free spins in total, per trigger!

If there are any risk-seekers, feel free to use the gamble feature. We RECOMMEND STAYING AWAY from it because gamble wagers do not count to wagering requirements.

Paranormal Activity (iSoftBet)

paranormal activity slot by isoftbet

Granted, the game is not precisely Halloween-themed, but the online gaming community seems to love it! It's our favourite horror slot game. It’s based on the blockbuster movie Paranormal Activity. ISoftBet has done a fantastic job, and their adaption on the reels is absolutely amazing. Paranormal Activity slot features 3 types of free spins. Each of them comes with a special bonus element, and in all honesty, we can’t decide which one’s best.

Paranormal Activity Slot Bonus Game

You need 3 BONUS Symbols to trigger the "Wheel of Bonus Features" which decides the bonus spins you win. Besides the 3 types of free spins, you can also win cash prizes. Personally, we like the free spins more, they are more volatile, but they also are way more rewarding.

  • Paranormal Free Spins – This type is probably the least volatile one, as you have a guaranteed win, 5 wins to be exact. You get UNLIMITED free spins, and they stop once you get 5 wins. Additionally, with every win, the multiplier increases up to a factor of 5.
  • Possessed Free Spins – Fitting to the movie, in particular, the Possessed Free Spins come in a batch of 10, and all of them include extra stacked WILDS to boost your chances of winning.
  • Demon Spins – Not 5, not 10, but you get 15 Free Spins of this kind. Besides getting 15 bonus rounds, there’s a small change in the paytable. The wild symbol is the Demon. Also, not only it substitutes for other symbols to create a winning line, but it can also possess neighbouring symbols, turning them into Wilds.

Before you get confused, Paranormal Activity is a 243 ways slot, meaning it does not have standard paylines.

Should You Play Halloween Slots Online?

Let's face it; if you're a slot player, you will want to try out something new, something different. It might as well be these glorious horror Halloween online slots, sweeten with a range of online casino Halloween bonuses.

However, when it comes to Halloween slot machines throughout the year, we'd recommend hunting down slots that are featured in online casino promotions and bonuses. Then again, we have to admit that the aforementioned online slots come with unique bonus games, that only a few popular slots can match. This is probably the reason why these slots attract a lot of noise in time for the holiday season.
