Game Review

Jack Hammer Slot Game

Step back in time with NetEnt’s comic book styled video slot, Jack Hammer. Drawing inspiration from the trashy pulp fiction detective books that were so popular till the 1950s this slot machine sees you caught in the ongoing battle between the gritty detective Jack Hammer and his arch-nemesis, the evil Dr Wuten.

You play the part of Jack’s erstwhile sidekick as you spin the reels in search of clues to this crazy whodunnit. Succeed in foiling Dr Wuten’s diabolical plans using Sticky Wins, Re-spins, Wild substitutions and Free Spins, and you could find yourself nabbing up to 3000x your bet as a reward.

Theme, Sounds and Symbols

Leaning into the illustrated novel-length hero pulps that were the forerunner of modern days comic books NetEnt has given Jack Hammer slot game a unique design style.

The towering metropolis that acts as the slot backdrop is given a dire crime-ridden feel through the inclusion of howling sirens and barking dogs. While the reels are made to look like the panels of a comic book with speech bubbles denoting the active reels and hard black borders encircling each symbol.

The reels contain four high-value panels. The panel containing our anti-hero Jack Hammer is the highest paying, while the Dr Wuten panel is the second most valuable. These closely followed by a Dame in distress and a plucky Paperboy.

The lower tier symbols showcase several threats to the city such as an evil Zeppelin, a Car Chase, a Newspaper with a disturbing headline, a ringing Phone and a vial of Poison.

There is also an explosive Wild symbol which will substitute for all symbols except the Free Spins symbol. The Free Spins symbol is a ticking timebomb that will unleash free games on the reels.

In keeping with the era the slot plays out in the musical score is a cool jazz track that fades in and out as you spin the reels.

Game Mechanics

While Jack Hammer slots action takes place on a 5-reel 3-row board in practical terms the game has 15 individual reels. This is due to NetEnt spinning each of the 15 available symbols separately and not in five predetermined reels.

Jack Hammer is a low variance slot with 25 fixed paylines and an average RTP of 96.96%. This means that while there will be a fair amount of action on the reels, not many of the wins will be particularly big.

That not to say Jack Hammer isn’t without its moments of adrenalin, triggering the special features puts you one step closer to potentially taking home that 3000x big win, which at max bet could be worth up to €750,000!

Special Features

In addition to the Wild substitutions, Jack Hammer offers players two additional entertaining features, Sticky Wins and Free Spins.

Sticky Win

Any winning combination, or payline containing three or more Free Spin symbols, will trigger the online slots Sticky Win feature. During this feature, the triggering symbols will remain on the reels, and the rest of the symbols will receive a free re-spin.

This offer the dual chance of creating larger and larger wins from base game symbols or, more specifically in the case of the Free Spins symbols, triggering the bonus round.

Free Spin

Given that Jack Hammer has 15 individual reels, it requires a minimum of 5 Free Spin symbols to trigger the free games feature.

Free Spins in Jack Hammer is quite the affair with the game offering up to 30 Free Spins depending on the number of triggering symbols, all wins receive an automatic x3 Win Multiplier and you can win additional bonus spins to keep the action going.

Play ‘On The Go’

With NetEnt’s future-proofing of all their casino games, Jack Hammer is available for you to enjoy on your desktop pc, as well as all of the latest Apple and Android devices.

CasinoWow Game Verdict

See here, and there is nothing we like more than taking out the trash. When you play Jack Hammer, you get to do this in style. Foil the villain’s plans, save the Dame and put away up to 3000x your stake for a rainy day. It doesn’t get better than that, so spin Jack Hammer today.
