The original Jack Hammer slot featured a 1930’s detective as he tried to put an end to mob boss Don Crabby’s criminal activity. Both characters reappear in Jack Hammer 2, with NetEnt opting to keep much of the theme the same.

There is, however, quite a lot of difference when it comes to how the slot is built; Jack Hammer 2 is structured around a 5-reel, 3-row format with a whopping 99 paylines in play.

Wins are formed from left to right, but every win — even in the base game — triggers what’s known as a sticky wins feature, where respins are awarded.

For a slot with 99 paylines, we were quite surprised to see the minimum bet at just $0.50. So, while it’s not the lowest min bet in the history of online slots, it’s low enough that the vast majority of players should be able to get in on the action without breaking the bank.

Jack Hammer 2 offers a max bet of $250 for those looking to high-roll, a huge amount and enough to satisfy even the biggest whales playing online today.

Game Options

NetEnt’s Jack Hammer 2 slot comes with the usual selection of in-game options.

For example, you’ll find yourself able to set off an autoplay function that sees up to 500 spins playing out automatically. This prevents you from needing to press the “spin” button on every spin manually.

You can also customize the autoplay function. So, for example, it stops automatically when one of the bonus round features is triggered or when you reach a max win cap that you’ve set.

There’s also a quickspin function (although this won’t be available to players from all countries), which significantly decreases the time it takes for each spin to play out.

It’s useful in a game like Jack Hammer 2 because spins can take quite a long time to play out due to the sticky win feature.

RTP and Volatility

Jack Hammer 2 is famed in the online gambling world thanks to its high RTP. It offers one of the best return to player percentages you’ll find out of any slot available today!

The RTP is fixed at 97.07%. Because of this, many online casinos exclude it from being used in conjunction with deposit bonus offers.

In terms of volatility, Jack Hammer 2 is a low variance game. That being said, it is possible to hit some nice big sticky wins, especially during the free spins feature. Don’t rule the game out because of its high RTP and low variance math model; winning symbols, thanks to the 99 payline format, can lead to nice sticky wins, especially during the bonus features. We’ll cover the details of this in just a moment.

Symbols and Payouts

Just like in the original Jack Hammer slot, Jack Hammer 2 offers symbols designed to look like they’re straight out of a comic book. NetEnt has done a really good job of making the icons look great.

In fact, when putting this slot review together, we were actually really impressed with how everything looked. Of course, Jack Hammer himself is worth the most, awarding a payout worth 10X your stake if you manage to land a 5-of-a-kind combo of him anywhere on the reels. Other symbols include a Microphone, Violin Cases, Speed Boats, Barrels, and a Wharf.

The game also has some other premium symbols, including a Pair of Goons, Don Crabby, and Pearl the Moll. Of course, Jack Hammer is the highest paying symbol, so you’ll want to keep an eye out for him!

Bonuses and Features

No video slot today would be complete without an array of bonus features, and Jack Hammer 2 has it all; the free spins feature, a sticky win bonus feature in the base game, and even random multipliers where all wins are multiplied by 3X!

Let’s check out the bonus features you’ll find in the Jack Hammer 2 slot below:

Sticky Win Feature

The Sticky Win feature is a pretty core part of the Jack Hammer 2 slot, and it’s present both during the base game and the main free spins bonus. It’s one of the reasons why so many players like playing Jack Hammer 2 Fishy Business, as it ensures constant action and, essentially, constant bonuses.

Each time you land a win, the symbols involved with the win will lock in place, and a respin will be awarded for free. If on this respin, any new winning symbols land, they are also locked in place, and another respin will be awarded.

This process continues until you either fill the screen with one same symbol or until you fail to land any new symbols. With enough symbols across the reels, Jack Hammer 2 Fishy Business’ Sticky Win feature can produce some really nice hits!

Free Spins Feature

It’s the free spins feature that makes Jack Hammer 2 what it is, however. To trigger the free spins, you will need to land five of the free spins symbols anywhere in view during the base game.

Landing five will award you with ten free spins, although it’s possible to win 16 free spins and 20 free spins, too, with the right number of free spin symbols.

Now, during the bonus, random wilds will be added to the reels before the start of each spin. These random extra wild symbols make it much easier to hit wins, which, in turn, then activates the respin feature.

It’s also possible for you to retrigger the free spins in the Jack Hammer 2 slot, and this is done by landing new scatter symbols. Again, you can win as many as 20 free spins — so they can play out for quite some time!

Our verdict

If you liked the original Jack Hammer online slot, there’s little reason to expect you won’t love Jack Hammer 2. NetEnt has managed to create a sequel that’s really gone down in history as being one of their best slot games.

We love how forming a winning bet line activates the respin feature, and the bonus spins hit very frequently, so you shouldn’t have to wait around long to see the bonus in action for yourself.

What’s more, the free spins mechanic (also known as bonus spins) isn’t overly hard to trigger, and we were awarded it several times while writing this review.

It’s also hard to ignore the incredibly high RTP, 97.1%. This is so much higher than most video slots released today, and it’s a fantastic find, especially since many casino sites are choosing to favour lower-RTP games.

We also like the fact that Jack Hammer 2 is available at many online casinos, and you shouldn’t have to look for long to find it.

Remember, if you’d like to play Jack Hammer 2 for yourself, you can try it out for free right here at Casinomeister! Who knows? Maybe you’ll manage to trigger the free spins bonus for yourself!
