Fans of the famous Jack Hammer comic books series are bound to love this game. The game features the same cartoon-like graphics and retro animations as the original, while Jack Hammer, the competent PI continues his struggle to save Grand City from the hands of evil Dr. Wüten, lord of the underworld.

Due to the success of Jack Hammer, NetEnt has launched a sequel, Jack Hammer 2 – Fishy Business, which also enjoys great popularity. Both games are only available online.

Game Description

Jack Hammer is played with 3 rows of 5 symbols. Unique to NetEnt, each symbol rotates independently, giving a total of 15 reels.

As with other NetEnt slots, the aim of the game is to complete winning combinations of 3-5 like-symbols appearing in succession from leftmost to right across an active bet line. The “Wild” symbol substitutes for all other symbols, except the “Free Spin” symbol, to help complete a winning combination.

There is no scatter symbol in Jack Hammer. There are also no “player’s skill” feature in this game, like the “nudge” or “hold” features, so spin results cannot be manipulated by the player.
There is also an Auto feature, which automatically plays the game for the number of rounds you select. You also have the option to set up Advance Autoplay Settings. For example, you can choose to stop Autoplay after a win, or when your cash funds are reduced or increased by a certain amount.

Paylines and Betting Options

jack hammer 2 slotJack Hammer is a 25-payline game. The number of active paylines is fixed to 25.

However, as in other NetEnt games, you can choose from 1-10 bet levels and freely adjust the coin value. The coin value ranges between 0.01-1. Depending on the coin value and bet level you choose, the bet per spin ranges between €0.25 – €250. Max bet automatically plays the game at the maximum bet level and the pre-selected coin value.

The current bet level, coin value, bet per spin and remaining coins/cash funds, remain displayed on the bottom of the screen during the game.

Bonus Features

Free Spins – in Jack Hammer, 5 or more Free Spin symbols anywhere on the reels, win you free spins (or bonus rounds). The number of free spins is according to the Paytable. For example, 5 Free Spins symbols win you 10 free spins, and 9-15 symbols win you 30 free spins. You can also win additional free spins during a free round.

Sticky Wins – this is another unique feature from NetEnt. A wining bet line or 3 or more Free Spin symbols trigger the Sticky Win feature. The symbols making up a winning combination are held in place, while all other symbols continue spinning, extending each spin and giving you extra chances for winning. The symbols continue re-spinning as long as wining beltlines come up. A no-win spin ends the Sticky Wins feature.

Multipliers – in Jack Jammer, all Free Spin winnings are tripled (!), except for additional free spins winnings.


jack hammer 1Jack Hammer is not a progressive slot game. The paytable payouts are relatively modest, with a maximum jackpot of 1000 coins for 5 Jack Hammer symbols. However the Sticky win feature and the Free Spin multiplier gives you plenty of opportunities for bigger winnings.

Also, according to NetEnt publications, the theoretical rate of return to player is 97%, which is relatively high.


Jack Hammer fans are in for a treat with this game. But this is simply another fun game from NetEnt, and I recommended it to all online gamers, for the first-rate computer artwork, the innovative game play, the many winning opportunities and more.
