Personal tester's opinion about Jack Hammer slot

A low dispersion of the winning and a short cycle, allow you to complete the bonus requirements at the 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" are triggered 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 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.

Review and recommendations of the testing team

Despite its outdated graphics and sound, Jack Hammer slot is still loved by many players, due to the high potential of a big win during the free spins feature.

  • In the main game, due to the many winning combinations, the slot is not too bad at keeping the balance; despite the fact, the top symbols are rarely issued.
  • This slot triggers the free spins feature in a big interval. Usually, it comes a series without any feature and then come to a wave of 1-2 features that are triggered in a row (10-15 spins interval). After that comes a series of spins without feature again.
  • In the free spins feature, the slot more often than in the main game gives out winning combinations with expensive symbols.
  • Of course, this slot is not able to give out x1000+ bets, but it is quite possible to get 50x - 150x total bets during free spins, which is not bad, considering the balance keeping in the main game.
    The minus of this slot is the reduced number of playing lines, 25, due to which the spins are not always successful. For fans of slots with a large number of playing lines, the Jack Hammer 2 is recommended, because it has 99 lines, although the payout is low.

It is recommended to play this slot for bonus money. The recommended tactic is to wait until you get the first bonus with a win of 80x - 150x of total bets, or a combination of top characters and then leave the slot.

Description of the slot machine

The embodiment on the game screen of the heroes of your favorite 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.

Sticky Win feature

  • The winning line (with three or more symbols) or three (or more) free spin symbols, dropped anywhere on the reels, trigger Sticky Win feature.
  • The reels with the pay combinations are kept, while the rest continue spinning to increase the chances of the winning.
  • The reels spin until there are no new winnings during the last spin. If a new winning symbol drops on any of the lines, which increases the amount of the winning, it is also kept, and the spin continues.
  • If there are no winnings and Sticky Win feature ends, all the current winnings will be paid out.

Free spins feature

While playing Jack Hammer slot in the usual spins (or during free spins) five or more “Free Spin” symbols, dropped randomly on the reels, activate free spins (or add free spins to current). The amount of free bonus spins on the amount of free spins symbols: 5 symbols - 10 spins, 6 - 16 spins, 7 - 20, 8 - 25 spins, 9 (and more) - 30 free spins. A x3 multiplier during the free spins feature is applied.
