What Is Steamrunners?

Steamrunners lifts players into a Victorian-inspired cloud city built on steampunk airships, gears and brass-toned machinery. The setting favors an adventurous, industrial-fantasy tone over a darker or comedic take on the genre, with a soundtrack of clanking gears and hissing steam reinforcing the mechanical theme throughout.

The grid runs on a 5-reel, 4-row layout with 14 fixed paylines, evaluating winning combinations from left to right. Standard symbols fill out the paytable alongside two distinct Gas Canister variants that drive the entire feature set.

Gas Canisters and Sticky Sky City Multipliers

Green Versus Purple Canisters

Green Gas Canisters spread outward and convert themselves along with adjacent low-value symbols into Wild symbols carrying a multiplier between x2 and x200. Purple Gas Canisters work on a broader scale, affecting every low-paying symbol currently on the grid rather than just the ones immediately adjacent. When multiple canister effects combine within the same sequence, their multiplier values stack together for a considerably larger combined payout.

Sky City, Gaslight District and Court of High Steam

Three scatters trigger Sky City Bonus, eight free spins where Wilds created by Gas Canisters become sticky and their multipliers double on every subsequent appearance, climbing all the way toward a genuinely substantial 5,000x ceiling on a single symbol given enough consecutive doublings. Four scatters unlock Gaslight District, ten spins that instead guarantee at least one Wild remains on the grid throughout the entire round, keeping a baseline of extra multiplier potential live on every spin. Five scatters reveal Court of High Steam, guaranteeing a Gas Canister on every single spin of its duration, making it comfortably the most consistent of the three modes for generating fresh Wilds.

Four feature buy options are available: BonusHunt FeatureSpins at 3x increases the trigger chance fivefold, SmokeShow FeatureSpins at 50x guarantees a Gas Canister on the very next spin, Sky City can be bought directly for 80x, and Gaslight District for 200x.

RTP, Volatility and the Realistic Odds

The highest available configuration runs at 96.32% RTP, with lower-paying variants also in circulation depending on the operator. Volatility sits on the medium-high end of Hacksaw's scale, reflecting a game whose real ceiling comes from repeated doubling rather than a single large multiplier reveal.

The 10,000x max win is most realistically chased through a hot Sky City round, where several consecutive doublings on the same sticky Wild can push an individual symbol's multiplier dramatically higher than what any single Gas Canister activation could achieve on its own. Bets run €0.10 to €100 per spin.

Similar Slots Worth Exploring

Players drawn to Hacksaw's spreading-Wild mechanics should also try The Wildwood Curse, another release built around sticky Wilds that chain and multiply across a respin sequence, albeit through a horror setting instead of a steampunk skyline. Fans of a doubling-multiplier structure specifically might also appreciate Aiko and the Wind Spirit's own escalating Wild multiplier system.

Our Verdict

Steamrunners earns its place in Hacksaw's catalog through the interplay between its two Gas Canister types, giving the base game a genuine sense of variety between a focused adjacent-symbol conversion and a broader grid-wide sweep. Sky City's doubling sticky multipliers are the clear highlight, turning a strong opening sequence into a legitimate shot at a five-figure single-symbol multiplier well before the round even ends. The steampunk cloud-city presentation gives the whole package a distinct visual identity, and medium-high volatility strikes a reasonable balance between accessibility and genuine excitement potential.
