Everything in this casino slot will make you feel a little bit scared – from the graphics to the sinister sounds. Halloween Jack is an online slot by NetEnt where a Jack O’Lantern character has the main role. There are some really detailed and chilling visual elements in this game and some of them are animated.

Halloween Jack comes with 5 reels and 20 paylines. The standard matrix is the place where you will find ten standard symbols – five of them are playing card symbols while the others include a rusty horseshoe, a raven, a bat, a demonic horse, and a vampire lady. The crypt is the scatter symbol and landing at least three of them will trigger 10 free spins.

In the free spins mode, the lantern symbol on the fifth reel can activate one of the three wild features. As you might have expected, the wild is represented by Jack O’Lantern. This symbol counts as all standard symbols and triggers a re-spin with a moving wild.

Number of paylines: 25
Return to Player: 95.99%
Maximum win (units): 50.000

My scary list of the best Halloween casino slots continues with Horror Castle, a game present on a few top-rated casino sites. We all know what happens in scary castles because we’ve seen tons of movies like this, right? But, the truth is that Horror Castle by Fugaso is not very scary because you will find cartoonish visuals in this game. Some of them actually make the game look funny.

Anyway, Horror Castle features 5 reels and 25 paylines. I appreciate the fact that they have included unique icons in this game like a chalice filled with position, a spider web, a ghoul, an owl, and an executioner. The Jack O’Lantern symbol is the game’s wild.

This means that it replaces missing basic symbols, but it also multiplies the wins by two. When it ends up on the first or fifth reel, the wild expands and activates a re-spin. In addition, hitting at least three howling wolves on the reels will activate ten free spins with expanded wild.


Facts about Horror Castle

  • Average RTP


  • A relatively new game
  • A nice mix of horror and humor

Return to Player: 95.51%
Maximum win (units): 25.000

The best Halloween casino slots usually have pumpkins in their stories. Well, this one has pumpkin in the title too. While we are talking about pumpkins, did you know that you can make some great desserts with pumpkins? Now back to the game, Pumpkin Bonanza is an enjoyable online slot game made by Playtech.

This is a game that relies on advanced graphics which include visual elements in different colors and a sinister background that looks like a haunted house.  Pumpkin Bonanza is played on 5 reels and has 10 paylines. It’s a simple matrix which is probably why this online slot has just seven regular symbols – four of them are represented by playing card suits, while the others include a straw man, a witch and a silhouette of a flying witch.

The pumpkin acts as a wild symbol which substitutes for all basic symbols. If you can create a winning combo in both directions but you miss a symbol, the pumpkin will appear in the middle and help you. It will also trigger a bonanza spin with more wilds.

  • It’s found on many reliable casino sites

Return to Player: 97.55%
Maximum win (units): 2500

I believe that the intention of the game developers, in this case, was to create cute visuals, but these visual elements are quite creepy and scary. Ghosts Night is an online slot game by World Match which deserves a place on any list of best Halloween casino slots because of the specific atmosphere created by the 3D-like visuals and impressive animations.

You will play on 5 reels and 25 paylines in this game. This is the industry’s standard, but what’s unique is the presence of nine regular symbols including a witch, a ghoul, a vampire, a coffin, a grave, a straw man, a Jack O’Lantern, a werewolf, and Frankenstein’s monster. Hit three or more crypts to launch 12 free spins with an x2 multiplier for the wins.

The skull which for some reason has eyes is the wild symbol which substitutes for all regular symbols. Finally, landing three Count Dracula bonus symbols will trigger a very daunting bonus round where you have to pick vampires to reveal prizes. It shouldn’t be difficult to find this online slot on more than one good casino site.

You can tell by the name of this online slot that the title is actually a play on words. Although it’s on the list of the best Halloween casino slots, HalloWin is actually a cute little game. I really enjoy it because this Cayetano Gaming online slot has very cute graphics which include funny icons in vibrant colors and a view of a haunted estate.

There are no surprising moments when it comes to the matrix of this slot – 5 reels and 20 paylines. On these reels, players can expect to find standard symbols like playing cards, a witch’s, juicy looking desserts (I wonder whether I should try to cook some of these or not), a purple bat and a Jack O’Lantern.

What I like is that the wild symbol comes in the form of a beautiful brunette vampire lady. It’s the symbol that promises top prizes, but it also replaces missing standard symbols on winning lines. Once you hear the pumpkin laughing (this happens at random and sounds creepy), you will get 10 free spins with locked wild symbols.

The first special symbol that you can make a combination with is the trick ‘o treat symbol which launches a trail bonus round.
