Jack Hammer: Slot Overview

Jack Hammer slot is classic game from NetEnt featuring comic style graphics in a hero versus villain showdown. The game was released back in July 2011, and it’s remained popular until this day (which should tell you a lot). It’s one of those games you’ll just keep returning to without really knowing why these rather simple features remain so fascinating.

The game is played out with a big city backdrop, and it comes with 5 reels, 3 rows and 25 ways to win. The Private Eye is the hero and the highest paying symbol, while the villain, Dr. Wuten, is the next in line (but not nearly as valuable). It’s really all about the sticky re-spins in the main game, and via this feature you can also trigger the free spins feature with a bit of luck.


Winning symbols will remain frozen on the reels, while the rest of the symbols re-spin. You need as many free spin symbols as possible to get a lot of free spins (up to 30 spins max), and therefore the sticky re-spins always come in handy. All wins in the free spins feature are tripled, and you can win up to 3,000 times your stake on this low variance game.


Jack Hammer: Slot Features


What symbols are there?

Jack Hammer comes with symbols as taken out of a classic cartoon strip from some old newspaper, and it’s cleary set in the 1930s. You’ll find one high value symbol, 3 medium value symbols and 5 lower value symbols on the paytable as follows:

What are the bonus features?

Whenever you land a winning combination on Jack Hammer slot, you’ll trigger the Sticky Win feature. All the winning symbols are locked in place, and the remaining symbols spin again. If you land a new winning combination, you’ll get yet another spin with the added symbol(s) becoming sticky too. This continues until there is no new winning symbol or wild symbol added to the mix. The total winnings are then paid out and the feature ends.


Free spins in Jack Hammer

You trigger the free spins feature on Jack Hammer when you land at least 5 scatter symbols on the reels at the same time. Of course, the more scatters you land, the more free spins you get. “Only” 5 scatters will give you 10 free spins, while 9 to 15 scatters will reward you with a total of 30 free spins. You can also land 6, 7 or 8 scatters, which will give you 15, 20 or 25 free spins respectively.


It does not matter how many free spins you get when it comes to the multiplier, cause your winnings will be boosted by 3x no matter what in this feature. It might sound a bit hard to get this many scatters, but remember that the sticky win feature goes for the free spins symbols too.

Jack Hammer: Slot Verdict
The original Jack Hammer is still going strong after all these years, which really says it all when it comes to the quality NetEnt has delivered here. The comic book style has a nostalgic appeal, and those locked in winning symbols just keep coming and it never gets old. The free spins feature offers a massive potential for a low variance game with the 3x multiplier on every spin. An undying classic we always return to for a good time.



  • Sticky win feature on every win in the base game
  • Free spins feature with 3x multiplier
  • A 3,000x potential on a low variance game



  • Some people prefer the sequel because of more paylines
