Jack Hammer vs Dr. Wüten is a pop-art-themed online video slot developed by NetEnt, which features five reels and 25 paylines with remarkable graphics and presentation.

Before you can set out on a daring adventure with Jack Hammer, you must first set your bet. Due to the nature of the game's Sticky Win feature, you must play all 25 lines.

Click the buttons to the left and right of Coin Value to change the coin denomination. Available sizes go from 0.01 to 1.00. Then, click the buttons by Bet Level to pick the number of coins on every line. Click the circular arrow button to begin, or use the Max Bet button to wager five coins on each of the 25 lines. You may also pick Autoplay to spin several times without interruption.

Jack Hammer matches or even surpasses any well-known cartoon title with its vibrant, comic book style presentation. The background features a mauve nighttime sky with Grand City silhouetted against it. All the windows are glowing yellow and to the right side of the background, you'll see Dr. Wüten’s blimp flying overhead, with a spotlight beam shining on it. The consistency in the design continues as payline numbers are enclosed in bright comic-style word bubbles that line each side of the screen.

There is no background music track that can be heard in this game, but gripping music builds up during the Sticky Win feature. An exciting, Big Band-style melody plays when you earn a winning combination, and an upbeat track keeps you engaged as you're playing in free spins mode.

There’s a lot to admire about Jack Hammer. The comic book graphics and illustrations complement each other very well and there’s a jazz style track to proclaim winning spins.

The streak spins and free spins have been seen in other slots and they’re both great features especially when you factor in the 3x multipliers in the free spins round.


Symbols come from the story, the highest-value being the hero himself, Jack Hammer. Next in line is the despicable Dr. Wüten, followed by a damsel in distress calling for help, and a classic newspaper boy from days of yore.

The lower set of symbols, in descending order of value, include Dr. Wüten’s blimp, a vehicle driven by goons, a newspaper with a "Mad Doctor Threatens Grand City" headline, a ringing telephone and a beaker full of bubbling orange poison.


Sticky Win Feature

This extra is initiated each time you land a winner. The successful symbols are frozen in place and the reels spin again. If you land a symbol that matches the original win or a wild, then they also lock in place and the process keeps on going. The re-spins continue until there’s one where no new symbol or wild joins the cluster. A payout is then made featuring all the matching symbols.

Free Spins

This round is sparked by landing five or more free spin scatters. The more scatters, the more free spins will be offered:

  • 9-15 scatters = 30 free spins
  • 8 scatters = 25 free spins
  • 7 scatters = 20 free spins
  • 6 scatters = 15 free spins
  • 5 scatters = 10 free spins

Regardless of the number of free spins you win, all payouts during this round are boosted by a 3x multiplier and trebled. Finding five scatters to trigger a round might sound challenging but the Sticky Win feature is your ally here.
