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.
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.
