How to play Jack Hammer mobile slot

The Jack Hammer slot is a low variance comic book-themed slot game created by NetEnt featuring Sticky Wins, Free Spins, a high 96.96% RTP and low volatility for quick wins.

Jack Hammer Vs. Evil Dr Wuten (to give this slot its full name) is a colourful mobile slot bringing you back to the heydays of Technicolor comic books.

NetEnt have introduced the sticky win feature for the first time in this Jack Hammer Touch mobile slot is often overlooked, with many heading to its sequel, Jack Hammer 2, for spinning thrills.

We think most people are mistaken because, as everyone knows, the original is often much better than the second instalment. Not by much, grant you; the follow-up slot has some decent features, but the original Jack Hammer slot game is the one we keep returning to time and time again.

The original Jack Hammer slot is always better

Why? Well, for one, considering that Net Entertainment gave both the same return to player rate of 96.96% (wonderfully and juicily high), you’d think that as this Jack Hammer game has 25 reels rather than 99 reels of the second, it would have less frequent wins. Quite the contrary.

Wins hit slightly more on the original (2% to 3%), which may not sound like a lot, but it is, especially as this Jack Hammer slot max win is 3,000x your total stake.

Both Jack Hammer slots are made to entertain with their sticky wilds and colourful graphics. Still, the original is slightly higher up the volatility scale due to that slight percentage chance and higher numbers hiding in the reels, making this video slot a far more exciting proposition.

Because that 3% starts to make all the difference when you realise that the maximum win in the free spins for the original mobile slot is £/$/€30,000, a huge increase from the sequel’s maximum win of €5,000.

If you managed to get your whole screen covered in sticky symbols during Jack Hammer 1, you could get as much as £/$/€10,000 on a single line bet. Jack hammer 2? £/$/€2,500.

Bam! Pow! Kaboom! Take that!

Are you starting to see why we favour the older brother? Especially as the fun graphics work just as well on both.

This real money slot game brings you a whole host of characters, removing the traditional J, Q, K, and A symbols for Jack Hammer, Evil Dr Wuten, a ringing phone, a car chase, a radioactive beaker, a paper boy, a damsel in distress and more. Add a hard-hitting, if elusive, free spins feature available, and we can lose ourselves in this little gem for many happy travelling hours.

Jack Hammer mobile slot not only works beautifully on iPads and tablets but loses nothing in translation from PC to Android mobile devices or iPhones, helping no doubt with its simple graphics to begin with.
