Halloween Jack Slot Overview
Halloween Jack is one of NetEnt’s best-loved Halloween slots. It came out on 24 October 2018, just in time for that year’s spooky season. The game plays on 5 reels and 3 rows, with 20 fixed paylines.
The story begins when a cursed jewellery box is opened, and darkness falls over a haunted town. Jack, a sinister jack-o’-lantern, leads the way through a creepy cemetery full of witches, crows and other dark creatures. It’s spooky, atmospheric and very well made.
The main attraction is the walking wild. Every wild gives you a re-spin and then steps one reel to the left. In the free spins, you can also collect lanterns to unlock bigger and scarier wilds. We refreshed this review in October 2026 and checked every figure against NetEnt’s own website.

Theme and Graphics
Halloween Jack is dark, detailed and properly creepy. The reels sit in a misty cemetery under a stormy sky. Meanwhile, haunting music and eerie sound effects give the feeling that something is watching you as you play.
The symbols fit the mood perfectly. Card ranks make up the lower-paying symbols. Above them, you’ll find dark creatures and cursed objects, including a witch, a bat, crows and an undead horse. A treasure chest acts as the scatter.
Jack himself is the star. He’s a menacing jack-o’-lantern who brings the wilds to life. As a result, the game feels more like a horror film than a cheerful Halloween party. If you’d prefer something lighter, try Happy Halloween instead.
Halloween Jack Betting Range
NetEnt lists the bet range as €0.20 to €100 per spin. All 20 paylines are always active, so you only need to choose your total stake. That makes the game quick and easy to set up.
The low minimum suits small budgets, while the €100 maximum gives room for bigger bets. Limits can differ slightly between casinos and currencies, so check the bet settings before you play.
RTP and Hit Frequency
Halloween Jack has an RTP of 96.28%. That’s in line with, or slightly above, the average for modern slots. In simple terms, the game is expected to pay back a fair share of stakes over the long run. Our guide to RTP and online slots explains how this works in plain English.
NetEnt also publishes a hit frequency of 34%. This means roughly one in every three spins lands a win. That’s a little lower than some NetEnt slots, so expect a few quieter spells between wins.
On the other hand, the 7,100x max payout is much bigger than many older slots offer. Most of that potential sits in the free spins, where the upgraded wilds come into play.
Topboss Group tip: Every wild in Halloween Jack brings at least one re-spin. So, a wild landing on the far right reel is great news, as it walks across all five reels before it leaves.
Halloween Jack Symbols
Walking Wild
The jack-o’-lantern is the wild. It stands in for other symbols to help form wins. More importantly, it triggers the Walking Wild feature every time it lands, as we explain below.
Scatter Symbol
The treasure chest is the scatter. Land three or more anywhere on the reels during the main game, and you’ll trigger 10 free spins.
Lantern Symbols
Lanterns only matter during the free spins. Each one you collect counts towards the Jack-o’-lector feature, which upgrades your wilds.
Halloween Jack Bonus Features
The game has three main features, and they all work together. Here’s a quick summary:
- Walking Wilds: every wild awards a re-spin and moves one reel left each time.
- Free spins: three or more scatters award 10 free spins, with more possible.
- Jack-o’-lector: collect lanterns in the free spins to unlock bigger walking wilds.
Walking Wild Feature
Whenever a wild lands, it awards a re-spin. Then, it shifts one reel to the left with each re-spin until it walks off the screen. If new wilds land along the way, they join in and keep the re-spins going.
This feature works in both the main game and the free spins. As a result, the base game never feels too quiet. A single wild on the right side of the reels can lead to a whole string of re-spins.
Free Spins
Land three or more scatter chests anywhere on the reels to win 10 free spins. The Walking Wild feature stays active throughout. In addition, NetEnt says you can win extra free spins during the round, so a good bonus can last longer than ten spins.
Jack-o’-lector Feature
This is the highlight of Halloween Jack. During the free spins, lantern symbols can land on the reels. Collect enough, and your wilds turn into something much more powerful.
| Lanterns collected | Wild unlocked |
|---|---|
| 3 | Stacked Hell Hound Wild |
| 6 | Stacked Jack-o’-lantern Wild |
| 9 | Expanding Death Reaper Wild |
Each of these upgraded wilds still walks left across the reels and triggers re-spins, just like the standard wild. However, because they’re stacked or expanding, they can cover far more of the screen. That’s where the biggest wins in Halloween Jack come from.
How to Play Halloween Jack
Halloween Jack is easy to learn, even if you’re new to NetEnt slots. Follow these steps:
- Set your stake: choose your bet. All 20 paylines are always in play.
- Spin the reels: press Spin, or use Autoplay for a set number of rounds.
- Watch the wilds walk: each wild gives a re-spin and moves one reel left.
- Look for chests: three or more anywhere start 10 free spins.
- Collect lanterns: in the free spins, 3, 6 or 9 lanterns unlock bigger wilds.
Wins pay from left to right along the paylines, starting on the first reel. The scatter chest is the exception, as it counts wherever it lands.
What We Corrected in This Review
Our earlier review had a few details that don’t match NetEnt’s current listing. Here’s what changed:
- Top win: we used to quote a 600,000 coin jackpot. NetEnt now lists the max payout as 7,100x your bet.
- Wild wins: the old review said all wild wins were tripled. NetEnt’s game description doesn’t mention this, so we’ve removed it.
- Extra free spins: we previously said a retrigger added 3 spins. NetEnt only says extra spins can be won, so we’ve kept to that.
Playing Halloween Jack on Mobile
Halloween Jack works on phones and tablets as well as desktop computers. It runs in your mobile browser on Android and iPhone, so there’s no app to download. The dark, detailed graphics also scale down well to a smaller screen.
Pros and Cons
Pros
- Walking wilds give re-spins in every game mode
- Three upgraded wilds in the free spins
- Strong 7,100x max payout
- Solid 96.28% RTP
- Dark, atmospheric horror theme
Cons
- Hit frequency of 34% means quieter spells
- Lanterns only count in the free spins
- Fixed paylines, so no way to play fewer lines
- Too dark for players who want a cheerful theme
Our Verdict
Halloween Jack is a genuinely spooky slot with features that build nicely on each other. The walking wilds keep the base game lively, and the Jack-o’-lector upgrades make the free spins exciting. Wins don’t land as often as in some NetEnt games. Still, with a 96.28% RTP and a 7,100x top payout, it’s one of the best horror slots to play this Halloween.
Similar Slots to Try
If you enjoy Halloween Jack, NetEnt’s Blood Suckers II is another great gothic choice. It has random features, tripled free spins and a treasure bonus game. Habanero’s Hot Hot Halloween takes a brighter approach, with row multipliers and locking free games.
Want something with a werewolf twist? Thunderkick’s Full Moon Romance mixes romance with moonlit horror. For pure haunted-house chills, Play’n GO’s House of Doom is worth a look.
