Tester's review

A low dispersion of the winning and a short cycle, allow you to complete the bonus requirements at the video slot (rating is 6.09 from 10). The probability of hitting any winning during the usual spins is close to 25% (each 4th spin). Also, "free spins feature"rarely triggering than usual in every 181st spin (statistically, 0,55%). The pool is divided into two parts: 80% is pay-out in the usual spins, and the rest is in "the bonus free spins feature". I recommend playing Jack Hammer 2 slot machine. In the first Jack Hammer you can play with a maximum stake of €50. King of Slots video slot is a complete clone of this machine. There was a bug in this slot - it paid much more when gambling in it with maximum (€250 per spin) bet, but Netent rebuilds its last years.

Description of the slot machine

Jack Hammer video slotThe embodiment on the game screen of the heroes of your favourite stories and detective themes are rarely combined at the games of Netent. But complex solutions have long become a privilege of NetEnt, attracting visitors not only with the originality of the plot but also an opportunity to make good money. By following this principle, NetEnt released its new slot machine about Jack Hammer.

The first thing that catches your eyes is the abundance of the thematic comic`s scenes. It is complicated to understand this diversity immediately, so the gambler, especially the one who triggered Jack Hammer video slot for the first time, has to analyse each element separately. The machine gets more brightness from its pay lines, designed as small colourful elements.

This video slot has a background of the city at night, in which the criminal life wakes up in the evening. In the luminous windows of the skyscrapers not only the happy families ready for sleep, but also the criminal authorities, once again debating their devious plans may be seen. The sound effects of the video slot thrill the gambler by their mystery, fully engaging him in the ambience of dangerous adventures. However, all NetEnt machines have their unique sound effects.

  • The maximum payout offered by Jack Hammer video slot is 750 000 coins. But the progressive jackpot and risk games for doubling the developers did not foresee, having decided, probably, that the experience in the emulator of the slot machine abound. The video slot`s RTP is 97%.


The flashing elements on the reels make you enjoy the detective plot that appears uniquely on NetEnt screen more and more.
