Steamrunners (Hacksaw Gaming) – Slot Review
Steamrunners transports players into a steampunk-inspired world of skybound adventure. Set high above the clouds aboard a floating airship and amidst levitating cities, the slot imagines an alternate reality powered by gears, gas, and mechanical innovation. The visuals blend industrial detail with a sense of whimsy—featuring brass fittings, glowing bulbs, intricate machinery, and sweeping views of cloudscapes and drifting islands that capture the spirit of exploration.
The symbols and characters further enhance the theme, showcasing inventors known as “Steamrunners” equipped with mechanical arms, mysterious gas canisters, and sky cities suspended in the air. Even the Wilds mimic swirling steam, spreading dynamically across the reels. A soundscape of gentle winds, mechanical hums, and rhythmic clanks completes the experience, striking a balance between adventure and artistry—energetic, inventive, and full of charm.
Steamrunners is a 5-reel, 4-row slot featuring 14 fixed paylines. This medium-volatility title offers a 96.32% RTP and a maximum win potential of up to 10,000x your bet. Wagers range from £0.10 to £100 per spin.
Steamrunners Symbols & Pay Table
The game features 14 symbols in total, including five low-paying symbols represented by 10, J, Q, K, and A. Premium symbols include Telescopes, Scrolls, Hats, Vinyl Players, and Goggles. Additional special symbols consist of a Wild, a Scatter, and two Gas Canister symbols — one Green and one Purple. The Wild is the highest-paying symbol, awarding 10x for five on a payline and substituting for all regular symbols.
Steamrunners Features & Mechanics
Wild Gas Canister Features
The Gas Canister symbols play a central role in Steamrunners’ gameplay. When a Green Gas Canister lands, it spreads horizontally and vertically, transforming itself and all adjacent low-paying or Wild symbols into Wilds if those transformations form part of a winning combination. The spread continues as long as new connected low-paying or Wild symbols are transformed.
The Purple Gas Canister functions similarly but with greater impact, transforming itself and all low-paying and Wild symbols on the grid into Wilds if they contribute to a win.
Transformed symbols may also receive random Multiplier values ranging from 2x up to 200x. Existing Wilds affected by Gas Canisters gain a 2x Multiplier. When multiple Wild Multipliers appear in a win, their values are added together before being applied. Only one Gas Canister can land per spin.
Bonus Game – Sky City
Landing three Scatter symbols activates the Sky City Bonus with 8 Free Spins. During this round, all Wilds with Multipliers become Sticky, locking in place for the duration of the feature. Each time a spreading Gas Canister affects a Sticky Wild, its Multiplier doubles, up to a maximum of 5,000x. Additional Scatter symbols during the bonus award extra spins — two Scatters grant +2 spins, while three grant +4.
Bonus Game – Gaslight District
Trigger the Gaslight District Bonus by landing four Scatters, awarding 10 Free Spins. This feature retains the mechanics of the Sky City round but guarantees that at least one Wild symbol remains on the grid throughout all spins. As in the previous bonus, landing two or three Scatters during the round grants +2 or +4 additional spins, respectively.
Hidden Epic Bonus – Court of High Steam
The ultimate feature, Court of High Steam, activates when five Scatter symbols land simultaneously, granting 10 Free Spins. This round includes all base game mechanics but adds a guaranteed Gas Canister symbol on every spin, significantly increasing win potential. Additional Scatters award the same spin bonuses as the previous features (+2 for two Scatters, +4 for three).
