Jack Hammer bonus, free spins & jackpot

Jack Hammer slot has two main bonus features, namely the Sticky Win feature and the Free Spins feature. Sticky Win can be triggered whenever you manage to form a winning combination on the reels. The winning symbols are locked in place as the reels spin one more time. Landing a wild or a symbol that matches the original win, means they will also stick in place, and you will be awarded another re-spin. This process is repeated until there are no new symbols to form winning combinations. Like most slots from this developer, the Jack Hammer free spin feature can be extremely rewarding.

To activate the spins feature you will need to land 5 or more free spin scatter symbols. The more scatters you land, the more free spins you receive in Jack Hammer slot. Landing five scatters will earn you 10 free spins and 6 scatters will award 15 free spins. 7 will earn you 20 free spins, and 8 will earn you 25 spins. Lastly, landing between 9 and 15 scatter symbols will earn you 30 free spins. All wins made during this round are subject to a generous 3x multiplier. The Sticky Wilds feature is active here and can give you the chance to reap maximum benefits.
