Jack Hammer NetEnt

Why just read comic books when you can play them? Jack Hammer takes players through a fight between superhero Jack Hammer and the Evil Dr. Wüten. The game features a unique graphical style and feature types. If you want to play for real money, just register at any reputable NetEnt casino.

Before you start your Jack Hammer adventure, set your bet. Due to the nature of the game's Sticky Win feature, you must play all 25 lines. Click the buttons to the left and right of Coin Value to change the coin denomination. Available sizes range from 0.01 to 1.00. Next, click the buttons by Bet Level to choose the number of coins on every line. Click the circular arrow button to begin, or use the Max Bet button to wager 5 coins on each of the 25 lines. You may also select Autoplay to spin several times without interruption.

Jack Hammer's biggest weapon against Evil Dr. Wüten is his Sticky Wins. Get any winning combination to trigger it. Once triggered, all winning paylines or scatters are held in place, and all other symbols are re-spun. The feature repeats itself until no additional wins are obtained. It's hard to find any other online video slot that gives you a feature so often. Jack Hammer also has a free spins feature triggered by 10 or more free spins at a 3x multiplier with 5 or more Explosive Scatters. Overall, Jack Hammer is the most entertaining (and potentially profitable) comic in history.

Jack Hammer is a 5 reel, 25 payline slot from NetEnt. This is a very highly volatile offering from Netent that can either drain your balance or give you a big win. I never really played Jack Hammer that often with my own money but started to love it when I learned the slots true potential in the Videoslots: battle of the slots. After that I started playing it more often in my personal capacity and I must say I always ended up with a smile in the end of my session.

Symbols on the reels you’ll see poison flasks, newspapers, phones, gun-toting mobsters and airships spinning around the reels. They’re joined by 4 higher value symbols. There’s a paperboy, a woman on the phone, the evil Dr Wuten and Jack Hammer himself.

This slot has a sticky Win feature - This extra is triggered every time you land a winner. The successful symbols are locked in place and the reels spin again. If you land a symbol that matches the original win or a wild, then they also lock in place and the process is repeated. The re-spins continue until there’s one where no new symbol or wild joins the cluster. A payout is then made featuring all the matching symbols.

Free Spins feature - this round is triggered by landing 5 or more free spin scatters. The more scatters, means more spins on offer:
• 9-15 scatters = 30 free spins
• 8 scatters = 25 free spins
• 7 scatters = 20 free spins
• 6 scatters = 15 free spins
• 5 scatters = 10 free spins

Regardless of the number of free spins you win, all pay-outs during this round are boosted by a 3x multiplier and trebled. Finding 5 scatters to trigger a round might sound tricky. The sticky win feature is in play in the free spins as well and you can re-trigger the feature.

There are a lot to like about Jack hammer but most importantly look out for you budget, as this slot can drain your balance easily. I love the slot and get constant x150 – x300 wins during free spins. I once got 0 coins during free spins LOL.

There are plenty of possibilities on 25 lines and if they stop symbols so the game continues until the symbols pair up so I think it's a very friendly game. The question of both good luck and skill is to stop the free spins, and then it's about how much FS you get. I play this game with the system and stop it, so I do not let the war to stop. Graphically, it is well-processed and belongs to older good hits. I like her.


It is necessary to have a higher capital, min. rotation on the game is only 0.50 C.

I'd not really spent a lot of time playing this, the original Jack Hammer, until recently - I've played a whole lot of Jack Hammer 2 and enjoyed it although found it quite infuriating at the same time! The original is pretty much in the same vein - the "reels" are a little different to most slots as all 15 positions on display have their own reel making it possible - one time in a billion no doubt - to get a full screen of any symbol as soon as the reels stop!

Much more likely is the possibility of you seeing a full screen of the same symbol following a number of "Sticky Wins" - this is a feature used by both Jack Hammer and its sequel whereby the reels will automatically respin after a winning combination giving you the opportunity to score a further, larger win. Because of this its possible to score many consecutive wins in a row without paying for additional spins!

Because of the 15 "individual" reels, you need at least five "Free Spin" symbols to trigger the free spins, which can be difficult, although the free re-spins help with this - thankfully you receive additional freespins for any extra "Free Spin" symbols too, all the way up to 30 free spins for 9 up to 15 free spin symbols. During free spins wins are tripled too.


One thing that confuses me a little about this game is that the jackpot win is stated as being just 1000x your stake (well, it is stated at 250,000 coins and the max bet is 250 coins...), however the top symbol pays out 1000 coins and with the 3x multiplier in free spins, a full screen of the Jack Hammer symbol should return 3000x your stake by my calculations. I'm not sure whats going on here, it could be a typo or mistake on NetEnts part, but I'm unsure.

All things considered I preferred Jack Hammer 2 - that game requires double the minimum stake at 0.50 per spin, but you play on 99 lines for that stake, which works much better for this type of game - it can feel very frustrating playing this game and getting lots of re-spins which result in no win, something that is very rare with the extra 74 paylines in Jack Hammer 2. It's not a bad game, but with a superior sequel its pretty much redundant now.
