Jack Hammer: Sticky Win Sequences and Tripled Free Spins
The short answer
Jack Hammer uses Sticky Win: winning symbols stay in place while other positions spin again, allowing the sequence to develop before its locked wins are paid. Its separate free-spin feature triples bet-line wins. These two features affect different parts of the round, so reading them separately makes the display much easier to follow.

How Jack Hammer Sticky Win works
The NetEnt game page describes a five-reel, three-row layout with 25 lines. A winning combination begins a sequence in which its symbols remain locked. Additional winning symbols or combinations can extend that sequence; settlement follows when the sequence finishes.
The useful question during the animation is which positions are already retained. Imagine labeling the grid by reel and row: R1–R5 and top, middle, bottom. Marking the locked positions on that simple grid lets you describe how the next screen builds on the previous one, without treating the two screens as unrelated initial spins.
A sequence log that keeps the amounts clear
Use one row for the initial paid round, with indented notes for its subsequent screens. Record the initial wager once, then record the amount that the final settlement actually credits. A subtotal displayed during an animation may already be part of the final amount.
Illustrative accounting example: a round costs $0.50 and eventually credits $3.50. Its displayed award equals seven times the starting wager, because $3.50 ÷ $0.50 = 7. The round’s net balance change is $3.00. Those are two useful descriptions of the same example, and neither requires counting every animation as a new purchase.
| Item to record | What it explains |
|---|---|
| Initial wager | Cost of starting the round |
| Retained positions | Continuity between Sticky Win screens |
| Final credited award | Amount settled when the sequence ends |
| Round identifier | Reference for reviewing that particular round |
Free spins and the 3× line-win factor
NetEnt specifies entry with five or more Free Spin symbols and a threefold factor on bet-line wins during the feature. The important scope is the eligible line win. For an illustrative unmultiplied line award of $1.20, applying 3× gives $3.60.
When reading the counter, identify whether it is showing the value before or after that transformation. If $3.60 is already the credited value, it already contains the factor. Keeping the stage of the calculation beside the number makes screenshots and session notes easier to interpret.
What to check in the edition you open
Confirm the complete title, provider, wager unit and feature help. Jack Hammer and a sequel with a similar name are separate titles. A publisher’s global product page also describes a product; the operator’s current catalog establishes whether a particular edition is offered in your location.
The guide to reading a paytable explains unit labels. For accounting, slot payout versus net result develops the distinction used in the example above.
Quick questions
Does a retained symbol mean a separately paid spin began? Read the round boundary and settlement record; Sticky Win describes stages within a developing sequence. What should a useful screenshot include? The wager, round identifier and labeled final award provide substantially more context than a cropped winning symbol.
