Halloween Jack Features

Prepare for spooky features with Halloween Jack as there are 3 big ones to help you remove the curse and gain the treasure.

It starts with the free spins round which can be triggered by landing 3 or more scatters. You'll win 10 free spins with the chance to win even more by landing 3 scatters during free spins.

The wilds also help out as they award a respin and move the wild one reel to the left. This finishes as soon as there are no wilds left on the reels.

Now, the final main feature is perhaps the most impressive. If you land laterns during free spins, then you can build them up to unlock 1 of 3 features. These include:

Halloween Jack - Free Spins

Free Spins

Scatters can appear anywhere on the reels and landing 3 or more can trigger the free spins round. Players will win 10 free spins with the potential to trigger 5 additional ones during free spins by landing scatters.

Halloween Jack - Walking Wild

Walking Wild

As soon as a wild lands on the reels, a respin is awarded and the wild moves on reel to the left. Ultimately, this continues until there are no wild symbols left on the reels. All wins with wilds pay x3 and can be activated in the main game and free spins.

Halloween Jack - Jack'O'Lector


At any time throughout free spins, the lantern symbol can land on reel 5 to unlock 1 of 3 features depending on how many lanterns symbols you collect.

Halloween Jack Review

Follow the tale of a young woman who accidentally discovers a cursed jewellery box that forces her to do unspeakable things. Even after she tries to dispose of it, Halloween Jack comes back with an even stronger wrath.

Developed by NetEnt, this horror and Halloween slot plays on 5-reels with 20 paylines. Players can win up to 3,000x the stake through the free spins, walking wilds and Jack'o'Lector!


As soon as you open up this slot, you'll notice an eerie graveyard full of graves and mist. The reels are set against a sacred tomb filled with creepy symbols.

Now, the symbols on the reels are straight from a horror film. The typical royal playing card numbers are there but with dirty hands all over them. To make matters even scarier, the other symbols include creepy creatures such as demonic bats or crows.

Music-wise - it's horrifying. There are deep bass and piano notes contrasted with high keys to make it suspenseful. This added with the ambient noises such as lightning and moans make it completely terrifying.

Overall, the design is fantastic and perfect for this genre of the slot. If you love something spooky, you are in the right place.


Despite the scary gameplay, it's quite tame for an online slot. All you have to do is set your bet, then spin and win. There are additional features but they are straightforward.

At the bottom left of the screen, you'll find the paytable along with a short story to get you in the mood for the slot. It's a nice little attention to detail that makes the slot even more terrifying.

Win Potential

Halloween Jack has a high RTP of 96.28% and a high volatility level. Ultimately, this means that players need a decent bankroll to sustain their gameplay.

The maximum win for this slot is 3,000x the stake which can be achieved by filling the reels with wilds during free spins or the spooky woman worth up to 1,000x your stake.

Our Verdict

There aren't many slots that look and feel fearsome - but Halloween Jack delivers. It's scary but retains entertaining gameplay with a solid win potential.

We honestly haven't seen anything like this before and our site, and we love it. Note that the volatility level is high, so if you are uncomfortable with this then we suggest trying Lucky Halloween instead. If you are a high roller and love scary slots, then definitely check out Halloween Jack for a frightful time.
