Halloween Jack Slot RTP, Details and Wager Limits

Reels/Paylines: 5 reels + 20 paylines

Stakes Range: 20p to £100 per spin

RTP: 96.28%

Max Win: 3,000 x stake per spin

The Halloween Jack slot is played on a 5 reel, 20 payline machine. Create winning combinations by land 3, 4 or 5 matching symbols from left to right on adjacent reels, starting from the leftmost reel.

The slot can be played from 20p to £100 per spin. To adjust your stake, simply click + or – either side of the coin value. You can do the same for levels too, which will adjust your stake too depending on the coin value selected.

You can set up to 1000 autospins and set them to stop if certain parameters are met like if a single win exceeds a certain amount. To view the paytable and to understand more about the slot overall, select the orange illuminated ‘i’ situated in the bottom left-hand corner.

The Halloween Jack RTP is 96.28%, which is slightly above average for this type of slot. With a hit frequency of 34.43%, you will land a winning combination on over a third of your spins on average.

The maximum win here is 3,000 x your stake, and the volatility is high.

Theme – a fang-tastic setting

Theme: Halloween

High Value Symbol: Lady Vampire

Compatibility: Mobile, Tablet, Desktop


With a typical Halloween theme depicting pumpkins, skeletons, vampires and more, it’s a game that certainly gets you into the spirit of things and ready for the October 31st festivities.

Visually, the Halloween Jack slot game looks fantastic. Lightning strikes in the background as the reels spin and wins are emphasised with bright orange lines to enhance the Halloween feel. Set within a ghostly, dark landscape, it has a harrowing soundtrack that is quite scary.

Symbols on the reels include A, K, Q, J and 10 royals which are creepily hugged by creatures’ hands. You’ll also see horseshoes, ravens, bats, horses and a female vampire. The vampire is the most rewarding symbol giving you 50 x your stake for 5 across a payline.

There’s also a scatter symbol that triggers the Free Spins feature with 3 or more in view, and a Walking Wild that moves one reel to the left with each respin. All wins with Wild symbols are multiplied by 3.

Halloween Jack Mobile


The Halloween Jack mobile slot gameplay is smooth and the visuals are great on a smaller screen. The game’s been fully optimised for all devices and can be enjoyed on both iOS and Android on smartphones and tablets.

Halloween Jack Bonus Features

There’s plenty of action to be had in this Halloween Jack slot game with 3 bonus features available. Highlights include the Free Spins feature, Walking Wilds, and a Jack ‘o’ Lector feature that can give numerous wild extras.

Walking Wild feature

The Halloween pumpkin symbol is the wild and substitutes for all symbols bar the scatter and lantern – it appears on reels except reel 1 in the base game. Any win involving a wild symbol will apply a 3x multiplier. When a wild appears, the Walking Wild feature is triggered.

A respin is then awarded. All wilds move 1 reel to the left with more re-spins to follow until no more wilds remain present on the reels. The Walking Wild feature can be triggered in the base game and the Free Spins feature.

Free Spins feature


The Free Spins feature can be entered when you get 3 or more treasure chest scatters anywhere on the reels. Your reward will be 10 free spins. If you get 3 or more scatters during the feature, you will win 5 more free spins taking your potential total to 15.

As mentioned, the Walking Wild feature can be triggered on any free spin and this happens when the wild appears on any of the 3 middle reels. Any winning combination involving a wild, like in the base game, is boosted by a 3x multiplier which really helps.

Jack ‘o’ Lector feature


Look out for the lantern symbol which only appears on reel 5 during the feature. When it lands, you will activate the Jack ‘o’ Lector feature, which gives you access to the following 3 wild extras:

Stacked Hell Hound Wild Collect 3 lanterns symbols with the next wild appearing on the reels becoming a 2-high Stacked Hell Hound Wild. This will then trigger the Walking Wild feature.
Stacked Jack-o’-lantern Wild Collect 6 lantern symbols with the next wild appearing becoming a 3-high Stacked Jack-o’-lantern wild. Again, the Walking Wild feature is then played.
Expanding Death Reaper Wild Collect 9 lanterns with the next wild becoming an Expanding Death Reaper wild symbol. You will therefore get a wild reel that shifts 1 reel at a time with each free spin.

RTP (96.28%)

Max Win (3,000 x)


I really like Halloween Jack. The gameplay is great and it’s crawling with ghosts and ghouls – what’s not to like? Variance wise it’s high with maximum wins of 3,000 x your stake on every spin. You’ll need a win involving a 3x wild to land the biggest win, though.

Overall, it’s a brilliant slot from NetEnt which is frightfully feature-packed with tricks and treats. If you like the theme, I highly recommend you play iSoftBet’s Paranormal Activity. We also have a full list of the best Halloween slots on our page dedicated to that time of year. Check it out.
