99 lines and a lock-in base feature

The recorded game uses five reels, three rows and 99 fixed lines, with bets from 0.50 to 250. It pays line wins, and the official record lists RTP 97.07%, volatility 3.9 and hit frequency 24%. The central base-game distinction is that a winning combination can change the next reel state: its symbols lock rather than disappearing immediately, leaving the remaining reels to spin again. The source does not state a separate cluster or ways model, so the review stays with its documented line structure.

Sticky Win and Free Spins

Sticky Win continues while new wins appear. Winning symbols lock, the reels spin again, and any additional wins also lock and award another spin. When no new win lands, the sequence ends and all locked wins are paid. Five or more Free Spin symbols anywhere on the reels trigger Free Spins at the same bet level as the trigger round. All line wins during Free Spins are doubled, and five or more Free Spin symbols can award additional spins. Random Wild labels may appear during the feature, but the record does not assign them a separate multiplier rule.

Configuration and limits

The maximum payout is 800 times the bet, with no maximum-win probability supplied. The Sticky Win sequence has a clear stopping condition, but the official record does not state the probability of another qualifying win or the maximum number of locked positions. The Free Spins duration is not supplied as a fixed starting count in the preserved description, so no number is invented. The doubled line-win rule belongs to Free Spins and should not be transferred to the base round. The practical comparison is about persistence: the sequel pays only after its lock sequence ends, so a player must distinguish an intermediate locked board from a completed result. That stopping rule is the feature boundary. The feature runs at the triggering bet level, whereas the doubled line-win rule applies only after Free Spins has started. Random Wild labels are noted inside that feature, but no separate payout treatment for them is documented.

Strengths and weak points

Strengths

The Sticky Win stopping rule is explicit, and the transition from locked symbols to a final combined payment gives the base feature a concrete visual progression.

Weaknesses

The preserved record omits starting Free Spins count, lock-position limits and maximum-win probability; the 800-times-bet ceiling therefore does not explain how often large locked totals occur.

Our Editor’s View

Jack Hammer 2 has a readable cause-and-effect loop: a line win locks symbols, the remaining reels spin, and another win extends the sequence. Once no new win lands, the locked total is paid. Free Spins then change the value rule by doubling line wins and allowing additional triggers. The evidence is less complete about starting Free Spins count, lock limits and outcome probabilities, while the 800-times-bet maximum has no frequency context. It suits readers who like incremental lock-in sequences without a separate cluster grid, provided they check the in-game rules for the omitted boundaries.
