Steamrunners (Hacksaw Gaming) Review

The Steamrunners slot transports you to a steampunk-inspired sky-city, where gas-powered airships and gear-driven machines hover among clouds where brass pipes, floating platforms, and mechanical detail give the slot a distinct “industrial fantasy” vibe.

The setting is playful yet adventurous: vibrant skies, metallic accents and cartoon-style art make Steamrunners slot visually engaging while you chase wins on the reels.

Before you spin, you set a few basic parameters then you’re off to the skies:

• Preferred Spin Options: You can spin manually to catch every “gas-canister spread,” wild transformation and multiplier reveal: or use autoplay to let the Steamrunners slot run at its own pace.

• Bet Options: Stakes run from 0.10 up to 100.00 coins per spin, which is flexible enough for low-stakes players and higher rollers alike.

• Turbo / Speed Options: The slot supports quick-spin features so you can speed up play if you like more pulsating gaming action. 

The Steamrunners slot uses a 5-reel x 4-row grid with 14 fixed paylines. Wins are formed by landing 3 to 5 matching symbols on a payline, from the left-most reel. The base RTP is 96.32% (though lower RTP variants ranging from 94.30%, 92.24% to 86.26% exist depending on operator.

The slot’s volatility is described as medium, balancing between frequency of smaller wins and the occasional bigger payout. The top payout potential is 10,000x your bet. 

• Low-value symbols are the standard card royals (10, J, Q, K, A).

• Higher-value symbols include steampunk-themed icons such as a telescope, scroll, top-hat, gramophone, and goggles. 

• Special symbols include a Wild, Scatter, and two kinds of Gas Canisters (Green & Purple), which trigger the slot’s main mechanics.

• Green Gas Canister: When it lands as part of a win, it spreads horizontally and vertically, converting itself and any adjacent low-value or Wild symbols into Wilds. This spreading continues as long as new convertible symbols connect allowing potentially large portions of the grid to become Wilds.

• Purple Gas Canister: More powerful if it lands, it transforms itself and all low-value symbols on the entire grid into Wilds (when part of a win). Additionally, transformed Wilds may receive a random multiplier between x2 and x200; any existing Wilds affected get a x2 multiplier. If multiple multipliers apply in the same win, their values are added together before payout. 
  
  These Gas Canister mechanics are the core “power plays” in Steamrunners; they can turn a bland grid into a cascade of Wilds and multipliers, greatly elevating win potential even in the base game. 

The slot features three distinct bonus rounds, triggered by landing 3, 4 or 5 Scatter symbols – each with its own twist.

• Sky City Bonus (3 Scatters): awards 8 free spins. During this mode, multiplying Wilds become sticky (stay in place) for the duration. Each time a Gas Canister affects a sticky wild, its multiplier doubles theoretically up to a massive x5,000 multiplier under ideal conditions. Additional Scatters (2 or 3) during free spins grant extra spins (+2 or +4).

• Gaslight District Bonus (4 Scatters): gives 10 free spins. Mechanics from Sky City apply, but with an added twist: at least one Wild is guaranteed on every spin. This ensures consistent action and reduces reliance on pure luck. 

• Court of High Steam (5 Scatters — “Hidden Epic Bonus”): also starts with 10 free spins, but one Gas Canister is guaranteed every spin, maximizing the chance of Wild conversions and high multipliers, making it the “big win” mode. 

Bonus Buy / FeatureSpins: The Steamrunners slot offers multiple fast-track options to jump directly into bonus content or enhance base-game modifier frequency: 

• BonusHunt FeatureSpins: Costs 3x the bet and increases the chance to trigger a bonus round. 

• SmokeShow FeatureSpins: Costs 50x the bet, and guarantees at least one Gas Canister symbol on the spin (boosting chance for wild spreads/multipliers). 

• Direct Free Spins Buy: Pay 80x the bet for Sky City, or 200x the bet for Gaslight District. 

I find the Steamrunners slot to be one of the most creatively executed slots by Hacksaw lately. Its steampunk sky-city theme is vibrant and appealing, and the Gas Canister mechanic adds strong volatility and excitement: transforming ordinary symbols into Wilds, stacking multipliers, and enabling massive win potential.
