Game play Jack Hammer™ 3: Diamond Affair slot

Embark on an exhilarating journey into the clandestine underworld, where Detective Jack Hammer™ and the daring Pearl unite in a heart-pounding quest to retrieve the coveted Blue Diamond from the sticky fingers of the infamous Madam Venom! Sticky Win™ makes Jack Hammer™’s formidable allies happy as winning symbols lock onto their places, and a respin’s intrigue unfolds. Jack Hammer™ symbols and high-win pay-out combinations fuel the Mysterious Multiplier progress bar, growing with multipliers for the entire Free Spins round. 


Wilds may show up on the reels across the main game, the bonus game of free spins, and during respins. Wilds substitute for all symbols, bar Free Spins and Jack Hammer™ symbols, and count as the highest possible winning combination on a Scatter Pays win.

Sticky Win™

NetEnt’s signature Sticky Win™ feature can occur during the main game and Free Spins, and awards respins. The feature activates when at least one Scatter Pays win or at least three Free Spins symbols occur to the reels.


When the respin activates, winning symbols forming part of Scatter Pays and Free Spins symbols remain on the gaming grid, and all the other positions spin again. You receive an additional respin when

  • a new symbol is added to the existing Scatter Pays winning combination,
  • a new Scatter Pays winning combination forms, or
  • a Jack Hammer™ symbol appears.

Respins end when neither condition mentioned above is satisfied or when all the positions on the gaming grid are occupied by winning combinations.

Wins are evaluated only after the last respin, based on the original wager at the beginning of the spin that triggered the first respin.

Jack Hammer™ Feature

When the Jack Hammer™ symbol appears on the reels during a respin, the unique Jack Hammer™ Feature activates in the main game and during Free Spins.

When the Jack Hammer™ symbol occurs during a winning combination of low-paying symbols, all these symbols turn into higher-paying peers. If more low-win combinations occur, all instances are upgraded into the same higher-paying win.

Each Jack Hammer™ symbol on the reels increases the win multiplier in the Mysterious Multiplier progress bar. Winning combinations of high-paying symbols also boost the Mysterious Multiplier.

The Mysterious Multiplier progress bar is reset during the main game when respins end. The Mysterious Multiplier maintains progress for the Free Spins and only resets at the end of the bonus round.

Mysterious Multiplier

When the Jack Hammer™ symbol occurs during a winning combination of high-paying symbols, they are added to the Mysterious Multiplier progress bar, increasing the multiplier.

When low-win symbols transform into high-win symbols, these are also added to the Mysterious Multiplier progress bar.

You need eight high-win symbols for 2x, 3x, and 4x multipliers in the Mysterious Multiplier progress bar. You need at least 20 symbols for multipliers of 5x or higher.

Free Spins

Free Spins scatters in the main game and bonus round bring you free spins. When you land 5, 6, 7, 8, 9, and 10 or more Free Spins scatters, you receive 10, 12, 14, 16, 18, and 20 free spins, respectively. Also, free spins are always tallied with the remaining free spins.

If the Mysterious Multiplier feature and Free Spins are activated on the same spin, Free Spins start, and the Mysterious Multiplier progression continues until the end of Free Spins.

Buy Feature

Even the best detectives may need to take the fast track sometimes. At 75x of the original wager, you can head straight into Free Spins!

Theme and Symbols

Head down to the heart of the cartoon-esque nocturnal city streets as you try to solve the mystery of mysteries in the spattering rain.

The low-paying symbols are cartoon representations of objects of intrigue: a detective map, K9 police doggy treats, a revolver, lipstick, and a pair of diamonds and rubies.

The high-paying symbols are the supporting characters of the plot: a policeman, a sniffy police doggo, two robbers, Pearl, and Madam Venom.

The wild is a diamond against a yellow backdrop with the text ‘WILD’ popping in the foreground.

The Free Spins scatter is a ferocious snake, slithering around a red Free Spins text.

The Jack Hammer™ symbol triggering the thrilling feature is no other than the protagonist of the investigation: Jack Hammer™!


No whistleblower connections or detective prowess can guarantee winning in NetEnt’s Jack Hammer™ 3: Diamond Affair, similarly to any other of our video slots. However, the Sticky Win™ triggering respins and Jack Hammer™ feature filling the Mysterious Multiplier progress bar offer a perfect fusion of noir cartoon gameplay.
NetEnt’s Jack Hammer™ 3: Diamond Affair is a quest you can enroll in for free of charge. However, if the intrigue of the night boosts your curiosity, you may decide to bet a coin here and there in this excellent sequel title of medium volatility, 96.08% RTP game with 1,332x max win potential.
