Personal testers’ opinion about Jack Hammer slot

  • This is one game with a short cycle and low dispersion of the winnings.
  • The slot scored 6.09 from 10 wagering points, which indicates that successful competition of the bonus requirements is very much possible.
  • The probability of any hit (winning) in the usual spins is near 25% (i.e. each 4th spin).
  • The Free Spins are triggered approximately every 181st spin (statistically, 0.55%). 
  • The prize pool division is 80% reserved for the payouts in the usual spins and 20% for the bonus.
  • If you liked the Jack Hammer slot - try playing the sequel; you will enjoy it too. 
  • In 2015 NetEnt released the King of Slots slot machine, a complete clone of Jack Hammer. 

Review and recommendations by the testing team

  • Even after a decade of its issuing and despite its outmoded already graphics and sound, the Jack Hammer slot is still treasured by a large number of players due to the big potential of a massive win during the bonus round.
  • The spins in the base game are full of winning combinations, with which the slot will not let you lose the balance, even though the expensive symbols hardly ever drop.
  • This slot triggers the Free Spins in waves. The bottom of the wave is a long interval (100+spins) without any bonus game. On the top of the wave is a series of 1-2 bonus games in a row (with 10-15 spins intervals between them). And then again bottom - top - bottom. During the bonus game, more often than in the usual spins, expensive combinations are issued. Sure is very difficult to obtain 1000x+ bets, but it is quite plausible to receive 50x - 150x total bets, which is pretty good, minding that the balance is also kept in the usual spins. 
  • Many players compare the 2 Jack Hammers machines and summarize that the original slot became redundant after the sequel was released. They might be right considering the limited 25 pay lines of the first Jack Hammer versus the 99 pay lines of the sequel - respectively, the maximum winning per single spin (announced by NetEnt ) is 990 000 coins. Indeed with a larger number of winning lines, the chance of dropping frequently better combinations is logically higher. Both slots have almost identical RTP; just the paytable of Jack Hammer 2 is lower. Be sure to launch Jack Hammer 2, and try your luck with it as well!

NetEnt declares the following probabilities

  • The slot machine's collective percentage pays back to the player is 96.96% (in a long-distance). 
  • 77.3% are reserved for payouts in the base game and 19.7% in the bonus round.
  • The probability of getting any hit (winning) in the main game and the Free Spins is 25.3%.
  • The maximum winning you can obtain with 1 coin per pay line is 10 000 coins and 30 000 coins in the usual spins and the bonus round.

Sticky Win feature

Any 3+ symbols on a winning line, or 3+ Free Spins symbols, dropped anywhere on the reels, is triggering the Sticky Win feature. The winning symbols are frozen in their place, but the rest keep spinning, which boosts the winning chances. If another winning symbol drops - it is also frozen - increasing the winning amount further, and the spin goes on. This continues until no new winning symbols fall on the grid. After that, the full accumulated amount from all the spins is rewarded at once.

Free spins feature

In the usual spins and during the Free Spins, 5+ free spins symbols, dropped randomly on the reels, activate the bonus round (or add Free Spins to the current number). 

The number of Free Spins depends on the number of free spins symbols received: 

  • 5 symbols - 10 spins,
  • 6 symbols - 16 spins,
  • 7 symbols - 20 spins,
  • 8 symbols - 25 spins,
  • 9 (and more) - 30 free spins.

All of the Free Spins wins are with a 3x multiplier.

  • First, we advise you to make DEMO runs on this game, explore the different features, and practice our tips on winning at the Jack Hammer slot.
  • This is an excellent slot to play for bonus wagering and for real money too. 
  • We strongly recommend the Jack Hammer slot to complete the requirements for the bonus money, as the game cycle is short and is good at keeping the balance in the base game.
  • Besides, the slot doesn’t need a big starting bankroll (80-100x total bets will be sufficient).
  • While playing with real money, we recommend the following tactic: use stakes that are multiple of 10. It is observed that the slot behaves well with such bets. But we do not advise raising the bet to more than 50 CAD. This is because higher stakes can severely impact your budget. 
  • Another strategy is to play only until one bonus delivers 80x-150x total bets or a similarly paid combination of top symbols. After that, you better take off.
