How to play

It is evident that NetEnt did not hold back in creating this online slot game. But to really enjoy the bonus game, free spins feature, and various winning symbols, you need to learn how to set up your bets properly.

Like the other online slots, you will find the controls at the bottom of the screen – right below the reels.

The first thing that you can do is to adjust the “Bet Level” on the left side of the controls. You can click the left and right arrows to adjust the level from 1 to 10. On the right side is the “Coin Value” that can be adjusted the same way. Click the left and right arrows to adjust between 0.01 and 0.5.

Since the paylines are fixed, your bet per spin will be 0.25 to 250. The bet level and coin value will always be multiplied and the product will also be multiplied by 25. The result will be the bet amount per spin. If you want to set the maximum bet, you just have to click the “Max Bet” button. This will set your bet per spin to 250.

Once you have set your betting preferences, you can click the “Spin” button that looks like two circular arrows. This will get the reels spinning. You can also click the “Autoplay” button to get the reels spinning with no interruptions.

Take note that there are other buttons on the bottom left side of the screen. This will help you with the various information that you may need as you play – like the paytable, settings, etc.

Slots special features

Playing the Jack Hammer slot is highly entertaining and quite easy to understand. But you have to go through the various special features to know the possibilities of winning.


NetEnt perfectly incorporated the theme in the various symbols used in the game. Like the other online slot games, there are low-value and high-value symbols.

The 4 higher-value symbols, from highest to lowest, are Jack Hammer, Dr. Wuten, a woman on the phone and a paper boy. The low-value symbols include Dr. Wuten’s blimp, drive-by shooter, a newspaper headline, telephone, and a flask filled with poison.

Wild and scatter symbols

The Wild symbol is represented by the “WILD” comic-book text with an explosive background. This can substitute for all the other symbols. This is for both high-value and low-value symbols. The only symbol that it cannot substitute is the Free spins symbol.

The Free Spins symbol is the scatter. It is represented by a Bomb symbol with the text “Free Spin” in front. If you get a lot of these scatter symbols, you get to trigger the frees spins feature. The more scatter symbols you get, the more free spins will be awarded to you. For 5 scatters, you get 10 free spins, 6 gives you 15 re-spins, 7 results in 20 free spins, 8 leads to 25 free spins, and finally, 9 to 15 scatters will trigger 30 free spins.

If you win during the free spin feature, you will enjoy a 3x multiplier. This can go as high as 120x. But the average multiplier is really 25x to 50x.

Sticky wins feature

What makes the game really exciting is the Sticky Wins feature. This is the one that will really lead to a lot of payouts.

When you get 3 or more winning symbols on a payline, these will convert into sticky symbols. The other symbols will re-spin. This will repeat until there are no more winning paylines. It can result in four to five wins for one bet.

If you happen to fill the screen with winning symbols, you get to enjoy up to 30x of your bet.
