Introduction to Jack Hammer
Did you know that Jack Hammer was the first online slot by global software giant NetEnt to feature the iconic Sticky Wins mechanic? Here’s another fun fact for trivia lovers: the slot became such a hit that NetEnt released a sequel, Jack Hammer 2: A Fishy Business, due to popular demand.
Many players will already be familiar with NetEnt’s impressive portfolio, with popular games like Starburst, Gonzo’s Quest, and Jungle Spirit: Call of the Wild. But Jack Hammer vs. Evil Dr Wüten holds a special place in fans’ hearts for its unique storyline and gripping comic-book style.
This is the game where we first meet Jack Hammer, a hard-boiled American private detective who is on a mission to take down the evil Dr Wüten and save his kidnapped girlfriend.
Comic Book Style Gameplay and Storyline

Playing Jack Hammer on a mobile phone often feels more like reading a graphic novel than spinning reels in a slot game.
Each symbol on the reels contributes to the detective narrative, with eye-catching illustrations such as:
- An airship with a skull-and-crossbones flying over a city under searchlights
- A vintage car on two wheels as Jack fires his pistol
- A gloved hand holding a bottle of toxic chemicals
- A ticking time bomb
- A newspaper reading “Mad Doctor Threatens Grand City”
- Dr Wüten creeping up behind a woman calling the police
- A comic-style paperboy shouting headlines
- And, of course, Jack himself, gun in hand
These visually rich symbols not only add to the immersive experience but also form winning combinations when they line up from left to right, starting on the leftmost reel.

Special Features

Bonus Features Explained
Sticky Wins
Sticky Wins are what made Jack Hammer famous. Here’s how it works:
- Whenever you land a winning combination or three or more scatter symbols, those winning symbols are held in place
- The other reels re-spin automatically
- As long as new winning symbols land, the re-spins continue
- This increases your chances of bigger and better wins
Free Spins Bonus Round
Trigger the bonus by landing five or more Scatter (bomb) symbols anywhere on the reels. The number of Free Spins you receive depends on how many bombs appear:
- 5 Scatter symbols = 10 Free Spins
- 6 Scatter symbols = 15 Free Spins
- 7 Scatter symbols = 20 Free Spins
- 8 Scatter symbols = 25 Free Spins
- 9–15 Scatter symbols = 30 Free Spins
All wins during this round are tripled (3x multiplier), and yes – Sticky Wins are active too!
