Jack Hammer 4: Chasing the Dragon

Jack Hammer 4 Chasing The Dragon moves NetEnt's cartoon-detective series into a fog-lit, noir-inspired Asian metropolis, swapping the earlier games' city streets for lantern-lit alleys, calligraphy signage and a skyline that echoes San Francisco's Chinatown. The same pop-art comic style and hard-boiled tone carry over from previous instalments, now wrapped around a dragon-themed criminal underworld that gives the game its title.

Chasing the Dragon plays out on a 6x6 grid using cluster pays rather than lines or ways, so any group of 6 or more matching symbols connected vertically or horizontally anywhere on the board pays out. A 6-symbol cluster returns between 0.3x and 1x the bet, scaling up to 7.5x-40x when a win fills all 36 positions on the grid.

Three Chinese-character tiles standing for fortune, dragon and peace sit alongside a ceremonial pot and a dragon statue as the lower-value icons, while the cast of Pearl, a mysterious raven-haired woman, the villainous elder Dragon and Detective Jack Hammer himself make up the premium symbols.

A Sticky Wins mechanic holds any cluster-winning symbols in place for a respin while the rest of the grid refills, repeating for as long as each respin improves the win and paying out once a respin fails to add anything new; the same hold-and-respin behaviour also kicks in whenever at least 3 scatters land.

Only a wild or a dedicated Question symbol can occupy the four corner positions of the grid, and landing one inside a winning cluster activates whichever effect it carries. A Multiplier corner adds a random 2x to 10x boost, an Upgrader swaps the cluster's symbols for a higher-paying type, a Cash Prize corner pays a flat 0.5x to 2.5x bonus, and an Expander adds up to 4 extra symbols into the winning cluster. The Question symbol pushes all four outcomes higher: it can turn into a bigger 30x or 50x multiplier, a Super Upgrader that jumps the cluster straight to the top-paying symbol, a Super Cash award of 10x or 25x, or a Super Expander that adds as many as 16 symbols to the win.

Five scatters anywhere on the grid award 3 free spins played in a hold-and-win format, opening with three multiplier tiles already on the board carrying a value of 1x to 100x. Any multiplier that lands sticks in place and resets the spin counter, while four extra mechanics take turns occupying the corners for the rest of the round: one adds a new row to the grid, twice at most; another drops three fresh multiplier tiles onto empty spaces, up to three times; a third doubles the value of multipliers next to it, capped at three activations; and the last totals up every multiplier on the board, removes them, and banks the sum as the round's collected win.

An Elevate menu lets players pay into the free spins round directly: a 2x buy doubles the odds of triggering it naturally, a 10x buy guarantees at least one wild feature activates along with a better free spins chance, and outright purchases run to 100x for a standard round, 300x for a super round that starts with 3 wild features and 5 scatters already in play, or 150x for a lucky-draw option.

Jack Hammer 4 Chasing The Dragon carries high volatility and a maximum win of 10,000x the bet, with a default RTP of 96.01% alongside 94.01% and 88.06% configurations, and bets running from 0.20 up to 400 per spin. The wide 6x6 cluster grid keeps wins landing steadily in the base game, but the stacked corner wilds and the hold-and-win free spins are where the biggest multipliers build.
