Jack Hammer slot review

If reading retro comic books and fighting nasty villains is something that brings you pleasure, then Ne tEnt’s Jack Hammer slot was made for you. Let’s take a stroll in a nighttime Grand City during the 1920-s and find out what dangers this place is hiding. The full title of this 2012 slot game is Jack Hammer vs. Evil Dr Wüten – it presents the private detective Jack who’s trying to save the city from the wicked doctor aiming to blow up and poison everything in existence. But the cool theme is not the only strength of this slot – in this review, we’ll go over the winning possibilities, bonus features and gameplay functions to see how and where you play this slot and get the biggest casino bonus on top of your slot winnings as well.

Jack Hammer slot features


This slot game is equipped with 5 reels, 3 rows and 25 paylines. The reels have a unique comic design and feature symbols including detective Jack Hammer himself, a distressed lady calling for help, the malicious Dr Wüten and a newspaper boy as higher-paying symbols and lower paying ones such as Dr Wüten’s blimp, a city newspaper, a ringing telephone, poison, Zeppelin, etc.

The wild symbol of the slot that helps you replace other symbols and create better winning combos is a typical comic speech bubble with the word Wild in it.

The scatter symbol is a dangerous bomb, but it brings all the lucrative things in this particular slot, so we are sure that you’ll be happy to see it on the reels. Apart from triggering the free spins round, the scatter bomb also activates the Sticky Win bonus feature. During this feature, all the reels that have the winning symbols will stay or stick in place, while the rest of the reels will keep spinning to give you a better chance of activating more paylines and get much bigger winnings. For as long as any additional wins appear on the reels you keep getting the re-spins, but once no more wins show up the feature will end, and the slot will go back to the base mode.

Jack Hammer Slot Free Spins

Oh, yes, the bomb! Did we already mention that we kind of like it? The scatter symbol plays a huge part in getting some serious amounts of free spins.

That’s a lot of free spins if you ask us. Have you ever seen a slot that gives 30 of them? That’s a rare generosity, but it doesn’t end here - all your winnings during the free spins round also get tripled with a cool x3 multiplier feature. A-Ma-Zing!

Jack Hammer slot graphics and sounds

We definitely appreciate Jack Hammer’s quirky and unique comic-book style design. Based on a famous Marvel comic story the slot has a cartoonish but rather dangerous vibe and perfectly encapsulates the 20-s gangster era. Speech bubbles, thick white lines around the symbols, jazzy soundtrack – all together it creates a perfect urban detective story set in Technicolor.

Jack Hammer slot - our conclusion

We will probably get tired even listing all the things that we love about this slot, but let us give it a try. Awesome idea, perfectly executed comic-style design, cool soundtrack, unique story, sticky wins, up to 30 free spins with x3 multiplier, huge betting range, 97% RTP and just a great experience overall. It’s no wonder that just two years after the first Jack Hammer NetEnt released a sequel called Jack Hammer: Fishy Business. Excellent slot, 100% entertainment guarantee!
