Jack Hammer

Jack Hammer is a detective-themed online slot by NetEnt. The slot's full name is Jack Hammer vs. Evil Dr. Wuten, and is not to be confused with its sequel – Jack Hammer 2 – Fishy Business. The game uses 1950s comic book graphics, and its star is a private detective called Jack who is on a mission to prevent a mad doctor called Dr. Wuten from terrorising Grand City.

The Jack Hammer slot is one of the first NetEnt online slots to use sticky wins – a feature which holds all winning symbols in position while the other reels are re-spun to give you the chance to secure even bigger prizes. There are also wild substitutions and a free spins bonus with triple win multipliers.

More about the Software Provider

It's been around since 1996 when it was formed by Pontus Lindwall of Cherry Games, and has since become one of the pioneers of the iGaming industry. To celebrate its 20th anniversary in 2016, NetEnt released a trilogy of slots based on musical legends – Guns N' Roses, Jimi Hendrix, and Motorhead.

Appearance and Sound Effects

Back in the first half of the 1900s, pulp magazines were all the rage and brought us heroes such as The Phantom Detective, Doc Savage, and The Shadow. Jack Hammer takes inspiration from these "pulps" with its graphics and theme to give you colourful comic strip effect reels which tell a story.

Grand City is the fictional location in which the P.I. known as Jack Hammer works, and you can see the silhouette of the city's high rise buildings and a bridge in the background. Each of the paytable symbols forms part of the plot. There's a newspaper headline warning readers that a "Mad Doctor Threatens Grand City", a ringing telephone, a ticking bomb, an image of Dr. Wuten laughing maniacally while holding a bottle of poison, a blonde heroine, a newspaper boy, a car chase, and Jack holding a pistol as he heads out to put an end to Dr. Wuten's deadly plans.

Bonuses and Special Features

In this game, you have a wild symbol which is easy to spot as it's an image of an explosion with the word "WILD" written on it. It can replace all symbols except the Bomb to help create winning combos.
The Bomb is the scatter symbol, and five or more anywhere on the reels triggers the Free Spins Bonus, where you get between ten and thirty free games depending on how many scatters initiated the feature. All prizes are tripled during the Free Spins Bonus.

After every winning spin, the Sticky Win Feature awards a free re-spin while holding all winning symbols in position, and you continue to receive re-spins until no new wins are formed.


Jack Hammer uses five reels, three rows of symbols, and twenty-five fixed paylines, and offers an excellent RTP (Return to Player Rate) of 97.00. The game allows you to create winning combinations from left to right on adjacent reels, starting with the leftmost reel.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.
