How does the sticky win continue in Jack Hammer 4?

A respin begins when a cluster win of 6 symbols lands or when 3 or more scatters drop. During the respins, winning clusters and scatters stay locked in place, and the round keeps going as long as new symbols join a cluster or more scatters land. As you’d expect from a NetEnt slot, it carries over the Jack Hammer series’ signature feature as is. Series fans will be familiar with the sight of a cluster that keeps growing once it sticks.

Why are the four corner cells special?

On the 6×6 screen, only question mark symbols or wilds appear in the four corners. When a corner symbol takes part in a cluster win, the wild triggers its own feature, while the question mark turns into a wild and then triggers its feature. The features are Expander, Upgrader, Multiplier, Cash Prize, and their super versions. If all four features go off at once, they trigger one after another in a set order.

How do the free spins work?

When 5 scatters land, 3 free spins begin with 3 multiplier symbols already on the board. During this round only multipliers drop, and the spin count resets to 3 each time a new multiplier appears. The corners hold the Unlock, Generate, Double, and Collect features, which trigger when a multiplier drops next to them. Generate places 3 multipliers at random, and Double doubles the adjacent multiplier.

What Elevate features are there?

Free Spins Hunt at 2x your bet doubles your chance of free spins, and Wild Activator at 10x guarantees at least one feature trigger. 100x opens free spins right away, 150x Lucky Draw gives you either free spins or Super Free Spins, and 300x opens Super Free Spins right away. With a range of price points, you can choose to suit your goal.
