Slot review: Steamrunners

Steamrunners takes you high above the clouds into a steampunk-style world where floating cities drift in the sky and gritty, gear-driven machinery hums beneath your reels. You’re joining the “runners” daring aerial engineers racing across steam-powered airships and gear-laden decks. The graphics are crisp and atmospheric: brass piping, clouds gliding past windows, whirring propellers and a backdrop of mechanical invention set the tone. While the theme leans familiar in the steampunk genre, Hacksaw Gaming delivers it with polish and flair. The gameplay feels like part expedition, part machine-lab, and each spin carries the promise of gears clicking into place and systems powering up.

Slot overview: Steamrunners

The game features a 5-reel by 4-row grid with 14 fixed paylines in the standard configuration. Bets begin at around 0.10 and go up to 100 per spin in many jurisdictions. The RTP is quoted at 96.32% for the main version, though alternate variants of 94.32% (and lower) may exist depending on market. Volatility is described as medium so you get a mix of action and patience. The maximum win potential is up to 10,000x your bet.

The base game lets you chase wins, but the real spectacle emerges when special symbols activate and mechanisms cascade across the grid.

Slot features: Steamrunners

Wild Gas Canisters: Two kinds of Gas Canister symbols may land: a green canister and a purple canister. When the green version appears, it spreads to adjacent low-paying and Wild symbols (horizontally/vertically) and converts them into Wilds. The purple version takes it further, affecting all low‐paying and Wild symbols on the entire grid when conditions meet. These conversions can carry additive multipliers ranging from x2 up to x200 on those newly formed Wilds.
Sky City Free Spins: Triggered by 3 Scatter symbols. Awards 8 spins. During this mode any Wild with a multiplier that landed becomes sticky for the remainder of the feature.
Gaslight District Free Spins: Triggered by 4 Scatter symbols. Awards 10 spins. Adds the condition that each spin must have at least one Wild symbol on the grid. Wild multiplier behaviour continues.
Court of High Steam Free Spins: Triggered by 5 Scatter symbols. Awards 10 spins. Adds the further guarantee that each spin will include a Gas Canister symbol, increasing the potential for large transformations. Landing additional Scatters during the feature gives +2 or +4 extra spins for 2 or 3 Scatters respectively.
Feature Buy Options: For players wanting to access the bonus rounds more directly, Steamrunners offers multiple buy-in options:
- BonusHunt FeatureSpins (3x bet) – enhances the chance of entering a bonus game.
- SmokeShow FeatureSpins (50x bet) – guarantees at least one Gas Canister symbol per spin.
- Sky City Free Spins (80x bet) – immediate access to the Sky City bonus.
- Gaslight District Free Spins (200x bet) – immediate entry to the higher-tier feature.

Our verdict: Steamrunners

Steamrunners stands out as a well-executed steampunk slot that balances accessible gameplay with high-potential mechanics. On the plus side: the Wild Gas Canister mechanic is lively, the multiple Free Spins tiers offer meaningful choices, and the max win of 10,000x gives a clear upside. On the flip side: the theme, while polished, doesn’t push beyond genre expectations, and the 14-payline structure is more modest compared to slots offering hundreds or thousands of ways to win.

Players comfortable with medium volatility and who enjoy symbol transformations and feature hunts will find this slot engaging and fun.
