Steamrunners (Hacksaw Gaming) – Review & Demo Play

The Steamrunners Slot Game

I took to the clouds with Steamrunners, a 5x4 steampunk slot from Hacksaw Gaming, set among skybound cities and glimmering sky courts. The metallic grid of pipes, lights, and cogs delivers 14 paylines paying left to right. Stakes run from 0.10 to 100 per spin, so I could pace sessions sensibly. The default RTP tops out at 96.32, though alternative versions exist, and volatility sits at medium. The vibe is clean, with a rogue airship hovering beside the reels.

For flavour, fierce, fearless Steamrunners ride gas-powered gadgets as wins land from 3 to 5 matching symbols. It is straight video slot play, yet the game’s edge comes from wild-making Gas Canisters and sticky Wild Multipliers during bonuses. The top payout reaches 10,000x the bet, so there is proper headroom without overcooking the maths. I felt the medium profile kept the base game steady enough while leaving room for spikes when canisters connect across the board.

Symbols and Payouts in Steamrunners

Steamrunners packs 10 regular symbols split into low-paying royals 10 to A and premium steampunk kit like a telescope, scroll, hat, gramophone, and goggles. Five-of-a-kind royals pay 1x the bet, while a 5-of-a-kind premium lands between 2.5x and 5x. The golden W wild substitutes for all regulars and pays 10x for five on a line. Wins require 3 to 5 matches along the 14 fixed lines from the leftmost reel, with only the highest win per line paid.

Steamrunners Slot Bonus Features

The engine piece is the Wild Gas Canister. A Green Gas Canister spreads horizontally and vertically, transforming itself and adjacent low-paying symbols into wilds if they are part of a win, and the spread continues through connected lows or wilds. The Purple Gas Canister can convert itself and all low-paying symbols on the grid when involved in a win. Transformed wilds may reveal additive multipliers from x2 to x200, while existing wilds hit by a canister receive x2. Only one canister can land at a time.

Sky City triggers with 3 FS scatters for 8 free spins. Wild symbols with multipliers turn sticky and stay fixed, and when a spreading canister hits them, values double, up to x5,000 per wild. Landing 2 or 3 scatters adds +2 or +4 spins. Gaslight District arrives with 4 scatters and 10 free spins, running the same core rules, but at least one wild is present on the grid throughout the feature, keeping lines alive while you hunt connected spreads.

Court of High Steam is the hidden epic, triggered by 5 scatters for 10 free spins, with one Gas Canister guaranteed on every spin and the same retrigger scheme of +2 or +4. If I wanted to shortcut, FeatureSpins did the job. Bonushunt costs 3x per spin and makes a bonus five times likelier. Smokeshow costs 50x and guarantees a Gas Canister each spin. Sky City and Gaslight District can be bought for 80x and 200x the bet, respectively.

How to Win at Steamrunners Slot

At its core, winning is about lining up 3 to 5 identical symbols along the fixed 14 paylines starting from reel 1. I kept my stake between 0.10 and 100 and used Autoplay and Turbo when I wanted quicker cycles. The canisters do the heavy lifting, so I favoured sessions where lows were plentiful, as they turn into wilds and can carry multipliers. The paytable updates to your stake, so checking values before switching pace helped me keep control.

Steamrunners Slot RTP & Volatility

Steamrunners runs on a medium volatility profile. The top RTP sits at 96.32, though other versions exist at 94.30, 92.24, and 88.26, so I always check the info panel. The maximum win is 10,000x across all modes. If a session would exceed that, the feature ends and awards the cap, which is standard for this maker. That ceiling is reachable when sticky multiplier wilds stack and double through repeat canister hits.

FeatureSpins carry solid figures as well, with Bonushunt and Sky City running at 96.31 and Smokeshow and Gaslight District at 96.26, while volatility shifts from average to high depending on the mode. In practice I found a balanced maths model in base play, with smaller hits ticking over, and larger spikes when a Purple Canister drops or sticky wilds start doubling. Bankroll swings exist, yet the ride felt fair for a medium setting.

Concluding Verdict on Steamrunners

Steamrunners feels like classic Hacksaw built around spreading rather than cascades. The metallic board, fierce, fearless theming, and those additive multipliers give every spin a touch of jeopardy. When Green or Purple Canisters chain through connected lows, the grid can swarm with wilds in seconds. The highlights are Sky City and Gaslight District, where sticky multiplier wilds do the heavy lifting, doubling towards x5,000 and carrying line wins far beyond their face values.

As a long-time player, I rate it a tidy steampunk entry with proper punch from the canisters and a clear route to its 10,000x ceiling. It is not the most forgiving chase for the hidden bonus, yet the four FeatureSpins give good control over how you approach it. If you like medium volatility with bursts of sky-high action when the spreads land, Steamrunners is worth a spin.
