The Jack Hammer slot was a huge hit upon its release in 2011. The game tackles a rarely explored detective theme and boasts a cartoon-like design that will appeal to every old-school comic book fan.

With the Jack Hammer online slot, NetEnt first introduced the sticky wins mechanics, which are applied to each payout combo and remain active for as long as the winning sequences appear on the reels. The result could be a series of consecutive hits — all at the cost of one spin. 

As a result of sticky wins, high RTP, and low variance, a regular supply of cash should be assured, which is why you can expect to have more playtime for your investment than on an average slot game. 

Our Jack Hammer slot review dives deep into the game's inner workings by examining its RTP, max payout, visuals, free spins, and more. 

Jack Hammer Theme

Throughout its innovative slot opus, NetEnt has referenced various books, TV shows, movies, and other products from pop culture. With Jack Hammer, it has gone the extra mile to create a storyline tailored specifically around the title. 

The game is set in a noir world of the 1930s and depicts Jack Hammer as a crime-fighting private investigator as he attempts to take down the nefarious Dr. Wuten. Every aspect of the design has been carefully crafted to match the theme — from hand-drawn symbols to animations.

Jack Hammer Graphics and Sound

The visual component and accompanying soundtrack of Jack Hammer are masterpieces. The design is executed in the style of an old-school comic book with a retro flair. A skyline of a grand city with glowing yellow windows forms the backdrop. 

The symbols in the Jack Hammer slot are all story-specific. The game does not feature card symbols like most other themed slot titles. Rather, we have an old-school ringing telephone, blimp, paperboy, gangster-driven car, worried woman, and our main characters. 

The music is as cool as the visuals, with the retro sirens, barking dogs, and the rustling of papers. A smooth jazz soundtrack plays in the background, adding to the tension. 

How to Play Jack Hammer

You can play the Jack Hammer slot in each of our NetEnt online casinos. Before you jump into the action, though (and after you’ve made your first deposit), make sure to claim the welcome bonus package. The best online casinos from our lists in this article typically welcome new arrivals with a hefty deposit bonus, and they often throw in a free spins bundle. Plus, you’ll come across other casino bonuses designed for slot players down the road. These come in the form of reloads, rebates, or classic free spins. 

When you set everything up and load Jack Hammer, the first thing you should do is check the game rules lobby and the pay table. This information will tell you everything you need to know about the Jack Hammer slot game, including bonus features, bet line structure, and special symbols.

Then, you should adjust your stake size via the coin button. Afterward, you can start your spinning session. AutoPlay is also available — you can set it to 10, 25, 50, 100, 250, 500, 750, and 1,000 auto rounds. The Quick Spin button, which significantly speeds up the gameplay when turned on, is adjacent to the Spin button. 

Jack Hammer Features and Gameplay

Jack Hammer slot game incorporates 5 reels, 3 rows, and 25 bet lines — a pretty standard structure for a slot game. Payouts are generated if three of the same symbols appear on a payline from left to right.

The game has an insanely diverse betting setup. The minimum bet is a mere $0.25, while the upper limit reaches $250. In between, there are 42 different staking options. It’s safe to say that Jack Hammer is a one-size-fits-all game in terms of wagering choices. 

The 96% RTP rate is considered a benchmark for online slots. Everything above this threshold is considered solid or high-paying. Jack Hammer takes it up a few notches as far as payback percentage is concerned, clocking in at 96.96%. This figure is in line with some of the best-paying online slots in the industry. 

Jack Hammer's low volatility isn't apparent from its max win, which is 3,000x the stake. Typically, low variance games have a payout potential in the 500x–1,000x spectrum. Once again, Jack Hammer exceeds expectations. The average big win during our sessions was 150x the stake. 

You can play Jack Hammer on a wide range of mobile devices, as the title is developed in HTML5. It’s well-optimized for both iOS and Android phones. 

Apart from the base game symbols, Jack Hammer has two special icons — a wild and a scatter symbol. The wild symbol substitutes all others (except for the scatters), while scatters serve as a prerequisite to triggering a free spins round.

Jack Hammer Bonuses and Free Spins

Two bonus features are the crux of the Jack Hammer slot — sticky wins and free spins. 

The sticky win feature is activated each time three or more symbols align on a payline and form a win, regardless of the combination of symbols involved. Those symbols that are part of the winning combo will remain locked in place (sticky) while the remaining icons on the grid will respin. The re-spin cycle will continue until no new winning combinations are formed or until a wild joins the cluster. 

To trigger the bonus spins, you need to land at least 5 scatter symbols, which could turn out to be a challenging task. The number of free spins you receive is determined by how many scatters were used to initiate the bonus round, as follows: 

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

In addition, all free spin wins are tripled. Plus, the sticky win can kick in, potentially producing a big payday.

After conducting a full Jack Hammer slot review, we found it to be a captivating game that brings forth one of the most rewarding features ever invented. In a way, it’s reminiscent of a cascading reels mechanic, but it’s better because the winning symbols are actually sticky and they stay locked in place as opposed to the tumbling reels, which eliminate them. 

Add to this a thrilling storyline and a retro/comic-book/cartoonish artwork, and it's easy to see why the Jack Hammer slot has been making headlines for over a decade. The high RTP and player-friendly math model are the icings on the cake. If it only had a progressive jackpot, Jack Hammer could easily overtake Starburst or Gonzo’s Quest as the provider’s flagship titles.

The detective/superhero theme doesn’t appeal to everyone, and that’s fine. There are plenty more fish in the sea. If you have an esoteric taste for NetEnt releases, we recommend Bloodsuckers with an industry-high 98% RTP and free spins or the legendary Starburst slot that needs no introduction. 

If you’re a sucker for IGT slots, Lobstermania 2 and Da Vinci Diamonds are well worth checking out. On the other hand, some Microgaming slots feature seven-figure progressive jackpots, which is something you may want to take into account too. You can also try Fishin Frenzy from Blueprint Gaming as well.
