Theme and Graphics

Jack Hammer rivals any well-known cartoon series with its colorful, comic book-style renderings. Grand City is silhouetted against a purple night sky in the distance, with all its windows flashing brightly. Dr. Wuten’s blimp is visible in the backdrop to the right, impaled by what appears to be Jack Hammer’s floodlight as it flies overhead. Payline numbers are encased in vibrant word bubbles that adorn each side of the screen, maintaining the design’s consistency.

How To Play Jack Hammer Slot

In Jack Hammer, each symbol spins independently, giving 15 spinning reels. The game features Sticky Win, where reels with winning symbols are held, and all other reels re-spin for a chance of bigger wins! And, of course – Free Spins!

Jack Hammer Slot Features

Three or more “Tic-Toc” Bomb Free Spin symbols triggers the Sticky Win feature, where the reels with the winning symbols are held in place, and the others continue to roll. The reels keep spinning as long as new wins are had—the explosive-looking Wild symbol substitutes for any other symbol, except for the Free Spin.


Wild symbols can appear throughout the game and will boost your winning chances. These special symbols substitute for other symbols on a line, making a big win more likely!

Sticky Wins

In Jack Hammer, any win you land will activate the Sticky Win feature. The winning symbols will lock in place, and the rest of the reels will spin. This feature will continue until no more wins are made, potentially leading to some massive wins. The Sticky Wins feature can also be activated by landing three or more scatter symbols.

Jack Hammer Free Spins

To unlock the bonus free spins round, you’ll need five scatters visible on a single spin. The more scatters you land, the more free spins you’ll unlock! Five will give you ten free spins, while you can receive up to twenty if you land more than nine scatters. 

During this bonus round, your wins will have a 3x multiplier applied to them, tripling your winnings!

Tips and Strategy for Jack Hammer Slot Game

Whenever you land a winning combination on the Jack Hammer slot, you’ll trigger the Sticky Win feature. All the winning symbols are locked in place, and the remaining symbols spin again. If you land a new winning combination, you’ll get yet another spin with the added symbol(s) becoming sticky too. This continues until no recent winning or wild symbol is added to the mix. The total winnings are then paid out, and the feature ends.

You trigger the free spins feature on Jack Hammer when you simultaneously land at least five scatter symbols on the reels. Of course, the more scatters you land, the more free spins you get. “Only” 5 scatters will give you ten free spins, while 9 to 15 scatters will reward you with 30 free spins. You can also land 6, 7, or 8 scatters, giving you 15, 20, or 25 free spins.

It does not matter how many free spins you get when it comes to the multiplier cause your winnings will be boosted by 3x no matter what in this feature. It might sound hard to get this many scatters, but remember that the sticky win feature also goes for the free spins symbols.
