How to play
NetEnt has designed Jack Hammer to be user-friendly, ensuring that both newcomers and experienced players can access all the essential features. The control panel is located beneath the reels, providing straightforward options for adjusting stakes and accessing information.
Set your “Bet Level” using the arrows on the left. Levels range from 1 to 10. On the right side, adjust the “Coin Value” with arrows, choosing between 0.01 and 0.5. The total bet per spin is calculated by multiplying your bet level by coin value, then by 25 fixed paylines. You can use the “Max Bet” button to play at the highest stake of 250 coins per spin.
To start the game, click the prominent “Spin” button. Autoplay is also available for uninterrupted spins according to your selected criteria.
Additional buttons, such as paytable access and settings, are positioned to the lower left, letting you tailor your play session or review symbol values and rules at any time.
RTP and payouts
Jack Hammer features an RTP of 96.96 percent, making it appealing for those seeking more frequent returns. The low variance means wins tend to occur quite regularly, though most are on the modest side. This approach helps maintain player balance, offering a steady stream of smaller payouts as you wait for larger combinations or bonus triggers.
Despite fewer big wins, the interactive features like sticky wins, multipliers, and free spin rounds keep each session engaging. The highest multiplier available during free spins can reach up to 120x, though typical multipliers sit between 25x and 50x.

Special features in Jack Hammer
The entertainment value of Jack Hammer is heightened by its special features, which enhance both the pace of play and the potential winnings.
Symbols
The selection of symbols in Jack Hammer is directly linked to its graphic novel inspiration. High-value symbols are Jack Hammer himself, Dr Wuten, a woman on the telephone, and a paperboy. The lower-value symbols include Dr Wuten’s blimp, a car with a gangster, the newspaper headline, a rotary phone, and a flask with green chemicals.
Wild and scatter
The Wild symbol is a bold “WILD” text set against an explosive background, which substitutes for all symbols except the Free Spins scatter. The scatter is depicted by a bomb emblazoned with “Free Spin”. Landing five or more scatters activates the free spins round, with awards distributed as follows: 5 scatters grant 10 free spins, 6 grant 15, 7 unlock 20, 8 provide 25, and 9 or more trigger 30 free spins. During these rounds, all wins are tripled.
Multipliers during free spins can rise to 120x, depending on the number of winning combinations achieved.
Sticky wins
The Sticky Wins mechanic is a favourite element in Jack Hammer. Any time a winning combination lands or three or more scatter symbols appear, those symbols remain in place while the other positions respin. If new matching or scatter symbols land, they too become sticky, and a further respin is awarded. This loop continues until no additional matching symbols appear, leading to potentially significant rewards within a single spin cycle.
If every space is filled with matching winning symbols, you can expect a payout close to 30x your original bet for that round.
