How to play Jack Hammer

Jack Hammer has a very unique design, with the 5 reels, 3 rows and 25 paylines looking just like the pages of a comic book. Forget everything you know and expect to see on a slot machine, Jack Hammer does things differently. First off, the style and design of the game emulates that of a comic book perfectly, with each position on the reel looking just like the individual cells of a comic.

The game symbols are all done in that vivid and eye-catching comic book style – with Jack Hammer, Dr. Wüten, a paperboy among other symbols filling up the reels. There’s a Wild symbol that substitutes all other symbols, except the Free Spin symbol.

Jack Hammer also does wins quite differently than your run-of-the-mill slot, with the Sticky Win feature that we’ll cover later. There’s a free spin bonus round that can be unlocked by getting 5 or more Free Spin symbols.

If you want to join Jack Hammer and help him take down the evil Dr. Wüten you can spin for as little as £0.25, or max out at £250.

Jack Hammer features

Jack Hammer has a lot of action packed into one slot, with the Sticky Win feature that constantly ramps up the excitement. The Sticky Win feature works by holding winning symbols on a payline and re-spinning the reels for free. If another matching symbol appears on a payline, you get another re-spin until no more matching symbols appear, the Sticky Win ends and all active wins are paid.

The slot game, Jack Hammer, has a Free Spin feature that is triggered by getting 5 or more Free Spin symbols on any position on the reels. While this may sound like a lot, remember the Sticky Win feature also applies to the Free Spin Symbol. In the Free Spins all wins are tripled (3x).

Free Spin feature

If you want to save Grand City, beat Dr. Wüten and claim your reward, then the Free Spin symbol is your greatest ally. To get into the Free Spins you have to get 5 or more Free Spin symbols on the reels, they can appear anywhere and don’t have to land on a payline. The Sticky Win also applies to the Free Spin symbols, so provided you get 3 on a spin, they are held and the other reels are re-spun until no new Free Spin symbols appear.

Depending on the number of Free Spin symbols you have on the reels, you could be awarded up to 30 Free Spins. Your task in the Free Spins is to foil Dr. Wüten’s evil plan by defusing his time-bomb. You’ll be well rewarded for your efforts with a 3x win multiplier on all wins in the Free Spins game.

Jack Hammer in-game bonus features

Sticky Wins
Jack Hammer features sticky wins that allow for winning symbols to stack up along paylines. The Sticky Win works by holding winning symbols that appear on a payline and re-spinning the other symbols. If another matching symbol appears on a payline, then it is also held and the reels are re-spun until there is no more winning symbols added and all active wins are paid. The Sticky Win feature really adds to the action of Jack Hammer, and brings constant excitement to the reels, with each spin having the potential to lead to some big wins.

Free Spins
The Free Spin feature is triggered by reeling in 5 or more Free Spin symbols on any position on the reels. The Sticky Win also applies to the Free Spin symbols, so once you have 3 on the reels, they are held and the reels re-spun. The max amount of Free Spins that can be won is 30, by getting 9 or more Free Spin symbols. The Free Spin round sees you foil Dr. Wüten’s evil plan, by defusing his nasty time bomb. You are given a 3x win multiplier on all wins during the Free Spin round as a reward for your efforts in saving Grand City from destruction.
