Jack Hammer 2: Fishy Business review
Jack Hammer 2: Fishy Business sends the hero of the first game underwater to rescue Pearl. NetEnt gives the sequel 99 bet lines, a Sticky Win mechanic, Wilds and a free spins round in which every line win is doubled. The numbers are gentle: Low volatility, a 97.07% RTP, a 24% hit frequency and an 800x max win. It is a game built for frequency rather than height.
Dive for Pearl: setting and layout
In the studio's story Jack dives into danger to rescue Pearl from a watery fate. The sequel is dated 2012 on the studio page and uses a 5x3 layout with 99 bet lines at most. NetEnt says the graphics were upgraded for this version, and that the game adds suspense and style to the slot action.
The studio lists 99 lines as both the maximum and the minimum, so every spin plays the full set.
Sticky Win
The base game is built around one mechanic. After a win, the winning symbols lock in place and the reels spin again. If the next spin adds more wins, those lock as well and another spin follows.
Sticky Win
Winning symbols lock in place and the other reels spin again. New wins lock too and trigger another spin. The chain stops when no new win lands, and then all the locked wins are paid together. A change in how the game behaves signals that Sticky Win mode is active, which builds anticipation.
Free spins with doubled wins
Five or more free spin symbols anywhere on the reels trigger the round. The spins are played at the same bet level as the triggering round, and a sign shows how many remain. All bet line wins during the free spins are doubled, which is the main reason to want the bonus.
Landing five or more free spin symbols in the round awards additional spins. Wild labels can also appear at random, and NetEnt says they represent the battle between Jack Hammer and Don Crabby. The round ends with a win presentation and a return to the main game.
Numbers for a low-volatility game
The catalogue lists a single RTP of 97.07%, a house edge of 2.93%. On $1,000 wagered that is an average cost of $29.30. Hit frequency is 24%, and volatility is Low.
A 100-spin session costs $0.59 on average at a $0.20 bet, $2.93 at $1 and $14.65 at $5, a stake of $500. The max win is 800x the bet: $160 at $0.20, $800 at $1 and $4,000 at $5.
From the first Jack Hammer to similar Low games
The catalogue lists Jack Hammer from 2010, rated Low with 96.96% RTP and a 700x max win. The sequel raises the return by about a tenth of a percentage point and the ceiling to 800x.
Other Low NetEnt titles close in numbers include King of Slots and Long Pao (both 96.96%, 700x), Dazzle Me (96.91%, 700x, 2015), Fortune Rangers (96.9%, 700x) and Motörhead (96.98%, 600x).
Pros
- Low volatility with a 24% hit frequency
- RTP of 97.07% and a house edge of only 2.93%
- Free spins double every bet line win
- Free official demo available
Cons
- Max win is 800x, low next to most current releases
- Sticky Win only pays the locked wins once the chain ends
- 99 lines are always in play, so each spin costs the full bet
Verdict
Jack Hammer 2: Fishy Business is a modest, steady slot: Low volatility, 97.07% RTP and a 24% hit frequency, with Sticky Win to extend wins and doubled line wins in the free spins. The ceiling is 800x, so large payouts are not the aim. A 2.93% house edge still means an expected loss, about $2.93 per $100 wagered, so set a budget and try the demo first.
