Jack Hammer Slot Review

Thwart the efforts of the Evil Dr. Wüten in the Jack Hammer slot machine, created by NetEnt and available at both online casinos and brick-and-mortar casinos across the country. Here’s a snapshot of the game to easily compare to other slots:

  • Slot RTP: 96.96%
  • Reel Array: 5 reels, 25 paylines
  • Min/Max Bets: $0.25 – $250
  • Progressive Jackpot: No
  • Key Features: Sticky Wins; Free spins
  • Volatility: Low
  • Maker: NetEnt

    Jack Hammer was first released in 2010. The game comes from a highly respected and player-favorite studio—NetEnt—and offers 25 paylines, an above-average RTP of 96.96%, and low volatility. This makes Jack Hammer the ultimate fit for most players. Whether you’re a seasoned spinner or a newbie, you’ll find something to enjoy in Jack Hammer (and its sequels).

    The betting denominations for Jack Hammer start at $0.25 and go up to $250. Every denomination covers all 25 paylines, so you don’t need to increase your bet for more chances to win. Because the game has low volatility, there’s lots of room to experiment with different wager amounts.

    Jack Hammer’s RTP is 96.96%. This is an above-average RTP, so the game is a top choice for players in search of good returns. Still, keep in mind that RTP is a theoretical measure. There’s no guarantee that you’ll win or get $96.96 back for each $100 wagered. However, the game is programmed to pay out at that ratio across its entire lifespan.

    At first glance, Jack Hammer appears to have five reels and three rows, which is kinda-sorta true. It bears that standard layout, but each symbol spins independently. This means the game plays more like it has 15 individual reels and rows. Visually, this makes the in-game action feel straight out of a noir detective comic—full of interacting story threads, stray clues, and constantly shifting details. Here’s a quick look at the pay structure for Jack Hammer. Winning symbols must appear in a payline from left to right to qualify.

    Jack Hammer Bonus Features

    Bonuses and features are added mechanics within a slot game. Typically, they trigger at random or when you land certain combinations of symbols. Features and bonuses tend to offer bigger rewards than base gameplay, though that’s not a hard and fast rule. Jack Hammer has two amazing bonus features.

    Jack Hammer Sticky Win Feature

    If you land three or more free spin symbols in a winning payline, you will start the Sticky Wins feature in Jack Hammer. The spaces with winning symbols stick in place (thus the name) while all the others re-spin. This keeps happening as long as you continue landing wins. Once a spin ends without a new win, the Sticky Win feature ends.

    Jack Hammer Free Spins

    During the main game, hitting five or more free spins symbols anywhere on the reels (not just in a winning payline) will trigger the free spins bonus. Here’s how the free spins break down.

    • Five free spins symbols: 10 spins
    • Six free spins symbols: 15 spins
    • Seven free spins symbols: 20 spins
    • Eight free spins symbols: 25 spins
    • Nine through fifteen free spins symbols: 30 spins

    The free spins are played at the same bet level as the spin that launched the bonus. During the bonus, you can win additional free spins. Wins during the free spins bonus are tripled, but that excludes any extra free spins won during the bonus.

    Jack Hammer Slot Machines Strategy

    You can use some strategies to enjoy slot games like Jack Hammer. Remember, though, that slots are games of chance. There is no way to guarantee wins. To maximize your fun with Jack Hammer and other slots, try these strategies.


    Don’t be afraid of slightly bigger bets.

    Jack Hammer is a low-volatility slot, so it may hit more than you’re used to if you play medium- or high-volatility slots. Jack Hammer tends to hit with high frequency, small-ish wins. However, be sure to stay well within your budget, and be prepared to lose more than you win. That’s the nature of online casino games.


    Play in demo mode.

    You can try the game for free on this page without using real money. Use this mode to get familiar with how Jack Hammer works.


    Take the game to go.

    Jack Hammer is great for quick mobile sessions because of its low volatility. Give it a try when you only have a few minutes. The action-packed slot is bound to give you some entertainment in a pinch.


    Try the sequels.

    Detective Jack Hammer returns in two other games, which we discuss in more detail below. Give them a spin for more Jack Hammer action.


    Use bonus money.

    Many online casinos will give you bonus money to jumpstart your play. This is an excellent way to try Jack Hammer without staking real money.

    If you like the Jack Hammer slot machine, we recommend checking out the direct sequels. NetEnt has two follow-ups to the popular game.

    Jack Hammer Sequels

    • Jack Hammer 2: Fishy Business sees Jack trying to rescue Pearl from a watery grave. The game offers a 97.07% RTP and plenty of great features. This one ups the ante with 99 paylines.
    • Jack Hammer 3: Diamond Affair takes a different approach. While the first two games have low volatility, the rating for this third installment is high. The RTP is 96.08%.

    Shadow Diamond Noir

    High 5 Games’ Shadow Diamond Noir has a similar feel to Jack Hammer, but it’s slightly less cartoonish. The realistic depictions of jet-setting elites make for stark contrasts with the dark and gloomy city that headlines the game.

    Mystery Express

    From IGT, Mystery Express has similar stakes but a different setting and inspiration. Spurred by the works of Agatha Christie and other mystery writers, Mystery Express takes place on a treacherous locomotive where everyone wants a slice of Europe’s biggest treasure.
