Jack Hammer, NetEnt’s broken-nose detective, is back. In Jack Hammer 3: Diamond Affair, Madam Venom tries to steal the Blue Diamond. You still do this in a purebred setting like the comic books.

Jack Hammer 3 - Slot Review

Compared to predecessors Jack Hammer 1 and 2, a big difference has been implemented. You no longer deal with paylines, but with a Scatters Pays win mechanism. Still, the coveted Sticky Wins feature is back in place.

The payout percentage has gone down and is now 96.08% high. The volatility is at medium which means you can expect some money back on a regular basis. Are you curious if this release improves the series? You can read how Jack Hammer 3 came out of the test in this slot machine review.

How to Play Jack Hammer 3

In Jack Hammer 3: Diamond Affair, NetEnt abandons the classic payline mechanism. In the 5 reels and 6 rows playfield, the Scatter Pays principle applies. This simply requires you to count the number of matching symbols in your playfield. If there are 8 or more, you win.

How much you win depends on the symbol and your bet. Per spin, you bet between $0.20 and $200. You can easily adjust the default value of $1 using the plus and minus buttons or by clicking on the amount.

PROs & CONs of Jack Hammer 3


  • Nice design
  • Sticky Wins
  • For mobile players
  • Large betting range
  • Medium volatility


  • Low maximum profit

Symbols and Payout

While spinning, you will encounter a total of 12 different symbols. It is important to know the order, as you will find out later. For starters, there are 5 low value symbols. You have a location icon, dog chunks, revolver, lipstick and diamonds.

Next, there are 5 characters that all give the same high payout. You have Madam Venom with her snake, blonde beauty Pearl undercover as a singer, two nefarious followers, a dog and a policeman.

The payout in Jack Hammer 3 is per total number of matching symbols. Moreover, it makes a big jump if you can fill your playing field.

Bonus features of Jack Hammer 3

If you counted correctly, we are still missing two symbols. These are linked to the bonus features of Jack Hammer 3. Actually, there is a third special symbol hidden in one of the features. So read quickly what you can expect extra.

Jack Hammer 3

The Scatter Pays mechanism combined with the Sticky Wins will keep you on the edge of your seat.

Sticky Win

As with its predecessors, the Sticky Win feature applies to Jack Hammer 3. Every time you hit 8 matching symbols or at least 3 Scatters, they become Sticky. You get a Respin to collect more of them. By spinning one of the following you will receive a new Respin. You can continue like this until your playfield is full of the same symbol.

  • At least 1 new equal symbol or Scatter.
  • An entirely new combination.
  • A Jack Hammer symbol.

The first two options are obvious on their own. A Jack Hammer symbol comes with extra rules. It changes all Sticky symbols with low payout into the same symbol with higher value. If this causes you to receive character symbols, or were already character symbols, it triggers the Mysterious Multiplier at the top of your playfield.

The Mysterious Multiplier gives character payments as a Multiplier. For x2, x3 and x4, you have a meter for 8 symbols each. After this, you need to collect 20 symbols to increase the multiplier. Your final combination is done times this Multiplier.

Wild Symbol

The coveted Blue Diamond is the Wild symbol of Jack Hammer 3. It substitutes for all symbols except Jack Hammer and the Scatter.

Free Spins Bonus

By collecting 5 or more Scatters, you trigger the bonus game. For 5, 6, 7, 8, 9 or 10+ Scatters, you will receive 10, 12, 14, 16, 18 or 20 Free Spins. During this bonus round, you are more likely to get a winning combination. In addition, the Mysterious Multipliers remain active until the end of the round.

Bonus Buy

If you don’t want to wait to collect 5 Scatters, you can use the Bonus Buy feature. In Jack Hammer 3, it costs you 75 times the bet to buy the bonus game. You then get an initial spin with 5 Free Spins Scatters, followed by a Respin that can yield even more symbols.

What do we think of the Jack Hammer 3 slot machine?

With Jack Hammer 3, NetEnt provides a new slot machine with a familiar design. Especially when it comes to Scatter symbols or when Jack Hammer passed a few times.

One big difference that you might not notice right away is that Jack Hammer 3 distances itself from computer users. The high playfield lends itself perfectly to a vertical mobile screen.

The biggest drawback is the low volatility and maximum profit. But this makes it an excellent slot for new or occasional players who don’t want to take big risks.


Jack Hammer 3 has an RTP of 96.08%. The Bonus Buy feature has a payout percentage of 96.07%.

In Jack Hammer 3, you try to collect the same symbol in your play area at least 8 times. It doesn’t matter where these are located.

Every time you hit 3 Scatters or a winning combination, you get a Respin. As long as you add new symbols or spin Jack Hammer, you keep on playing.

Yes, by collecting 5 or more Scatters, you get 10 or more Free Spins. During the bonus round, winning combinations seem to occur more frequently.
