Theme and Visuals
Hacksaw Gaming has constructed a steampunk paradise that actually feels lived-in rather than a brass-plated afterthought. The 5×4 grid floats against a backdrop of fractured cities suspended in mechanical skies—think Jules Verne met Mad Max at an aviation convention. Airships drift through copper-tinted clouds while gears and pistons frame the reels, creating an atmosphere that’s both industrially gritty and romantically adventurous. You can try it yourself in our slot demos section.
The symbol design commits fully to the aesthetic: high-paying symbols include a brass telescope, weathered scroll, distinguished top hat, vintage gramophone, and aviator goggles—each rendered with the kind of detail that makes you want to reach through the screen and adjust the monocle. Low-value symbols use stylized playing card ranks (10-A) that feel appropriate rather than lazily inserted. The golden “W” Wild symbol gleams like something you’d find in a captain’s quarters, while the Gas Canisters—those brilliant green and purple pressure vessels—pulse with barely contained energy. When they activate, steam literally erupts across the reels. It’s not subtle, but neither is piloting a steam-powered dirigible through a fractured sky city.
How to Play Steamrunners
Playing Steamrunners is straightforward once you understand the Gas Canister transformation system. Here’s your complete flight manual:
- Launch the game and let the steampunk cityscape materialize around you.
- Set your bet using the stake controls—minimum $0.10, maximum $100 per spin.
- Understand the paylines: The 5×4 grid uses 14 fixed paylines. You need at least 3 matching symbols on a payline from left to right to win.
- Hit spin or enable autoplay for continuous action.
- Watch for Gas Canisters: When Green Canisters land as part of a winning combination, they spread horizontally and vertically, converting connected low-paying symbols (10-A) and existing wilds into new wilds. Purple Canisters are even more powerful—they transform ALL low-paying symbols across the entire grid into wilds.
- Track multipliers: Newly created wilds receive random multipliers from 2x to 200x. When multiple wilds with multipliers appear on the same winning payline, their values add together before being applied to your win.
- Collect scatters: Land 3, 4, or 5 FS scatter symbols to trigger Sky City, Gaslight District, or Court of High Steam free spins respectively.
Pro Tip: Gas Canisters only activate when they’re part of a winning combination. A lone canister sitting in the corner won’t do anything—it needs to be connected to a win before it unleashes its transformative power.
Symbols and Paytable
Steamrunners uses 14 fixed paylines across a 5×4 grid. The paytable is intentionally modest in the base game—the real firepower comes from Gas Canister transformations and stacked multipliers. Here’s what each symbol pays for a 5-of-a-kind combination:
| Symbol | 3 OAK | 4 OAK | 5 OAK |
|---|---|---|---|
| Wild (Golden W) | — | — | 10x |
| Goggles (Premium) | 0.5x | 2x | 5x |
| Gramophone (Premium) | 0.4x | 1.5x | 4x |
| Top Hat (Premium) | 0.3x | 1.2x | 3.5x |
| Scroll (Premium) | 0.25x | 1x | 3x |
| Telescope (Premium) | 0.2x | 0.8x | 2.5x |
| Ace (Royal) | 0.1x | 0.3x | 1x |
| King (Royal) | 0.1x | 0.3x | 1x |
| Queen (Royal) | 0.1x | 0.3x | 1x |
| Jack (Royal) | 0.1x | 0.3x | 1x |
| Ten (Royal) | 0.1x | 0.3x | 1x |
Payout Examples
- Betting $1 and landing 5 Goggles awards $5 (5x multiplier).
- Five Wild symbols on a $5 bet pays $50 (10x × $5).
- All five royal card symbols (10-A) pay identically: just 1x for five of a kind—$1 on a $1 bet.
- But here’s where it gets interesting: if those Wilds carry multipliers from Gas Canister activation, a single 5-Wild line with a 50x multiplier on one wild suddenly pays $250 instead of $50.
The deliberately low paytable values are the point—Steamrunners is designed around wild transformation and multiplier accumulation, not base symbol payouts. Those royal symbols paying just 1x for a full line? They’re canister fodder, waiting to be converted into multiplier-laden wilds.
Wild Symbols
The golden “W” Wild substitutes for all regular pay symbols to complete winning combinations. Five Wilds on a payline pay 10x your bet. But the real magic happens when Gas Canisters create wilds—these newly minted wilds receive random multipliers between 2x and 200x. When a canister hits an existing wild, it grants a 2x multiplier boost. Multiple multipliers on the same winning payline add together before being applied, creating potential for massive combined multipliers.
Gas Canister Symbols
These are the stars of the show. Two canister types operate differently:
Green Gas Canisters: When part of a winning combination, they spread horizontally and vertically from their position, converting themselves and any connected low-paying symbols (10, J, Q, K, A) or existing wilds into new wilds. The chain reaction continues until no more conversions are possible—like a chemical reaction you actually want to see in a lab.
Purple Gas Canisters: The nuclear option. When activated as part of a win, they transform ALL low-paying symbols across the entire grid into wilds—regardless of position. A single Purple Canister can turn a mediocre board into a wild-heavy playground.
Slot Features
Gas Canister Mechanic
This is Hacksaw Gaming’s core innovation for Steamrunners—a transformation mechanic that turns the weakest symbols on the board into your biggest allies. Unlike the DuelReels mechanic in Wanted Dead or a Wild, Gas Canisters work through symbol conversion rather than direct confrontation. Think of them as alchemists who’ve finally figured out how to turn lead into gold (or at least, how to turn card royals into multiplier-laden wilds).
When Gas Canisters land and form part of a winning combination, chemistry happens. Green Canisters spread outward in a cross pattern, converting adjacent low-pays and wilds into new wilds with multipliers. Purple Canisters skip the local approach entirely—they convert every single low-paying symbol on the grid, creating wild explosions that can fill most of the screen.
The multiplier system is where things get genuinely exciting. Newly created wilds receive random multipliers: 2x, 3x, 4x, 5x, 10x, 15x, 20x, 25x, 50x, 75x, 100x, or 200x. When an existing wild gets hit by a canister, it receives a 2x boost instead. And here’s the crucial detail: multipliers on the same winning payline ADD together. A win passing through a 10x wild and a 25x wild doesn’t multiply—it combines for a 35x boost applied to your line win.
Pro Tip: The mathematical ceiling on base game wins is significantly higher than the paytable suggests because of multiplier stacking. Don’t dismiss a spin just because it looks weak—watch for those canisters connecting to wins.
Slot Bonus Features
RTP & Volatility
RTP (Return to Player)
Steamrunners has a default RTP of 96.32%, sitting comfortably above the industry average of 96%. However—and this is crucial—Hacksaw Gaming offers multiple RTP configurations for casino operators: 94.30%, 92.24%, or a punishing 86.26%. The gap between 96.32% and 86.26% is over 10 percentage points, meaning you could be giving the casino an extra $10 per $100 wagered on the lowest version without even knowing it. Always check the game’s information screen before playing to verify which RTP version you’re actually spinning.
Volatility
This is a medium volatility slot, rated 3 out of 5 on Hacksaw Gaming’s scale. The hit frequency is 20.7%—roughly 1 in every 4.8 spins produces a win. This is notably higher than high-volatility slots like Le Bandit (which often drop to 15-18% hit rates), making Steamrunners more accessible for players who don’t enjoy extended dead spells.
Medium volatility creates a different rhythm than Hacksaw’s more brutal offerings. You’ll experience regular small-to-medium wins keeping your balance stable, punctuated by occasional larger hits when Gas Canisters create multiplier-heavy wild clusters. It’s less of a rollercoaster than high-volatility slots, but the 10,000x max win potential means those Gas Canister chain reactions can still deliver substantial payouts.
Pro Tip: Medium volatility doesn’t mean “easy” or “guaranteed profit.” It means the variance is distributed differently—you’ll see more frequent smaller wins rather than extended droughts followed by explosions. Budget accordingly: 50-100x your bet size is reasonable for extended sessions.

- Weak base paytable—royal symbols pay only 1x for five of a kind without canister activation
- Gas Canisters only activate when part of winning combinations—many land uselessly

Conclusion
Steamrunners delivers exactly what its steampunk premise promises: a mechanical symphony where the dual Gas Canister system transforms mundane card symbols into multiplier-laden wilds. The medium volatility positioning (20.7% hit frequency) is a smart departure from Hacksaw Gaming’s typically brutal variance—you’ll see wins regularly while multiplier stacking creates genuine big-win potential.
The RTP variance (96.32% down to 86.26%) remains problematic—always verify your version before playing. The unpurchasable Court of High Steam rewards patient players who trigger it naturally rather than bonus buyers. Best suited for players who appreciate mechanical innovation, enjoy transformation-based gameplay, and want a steampunk slot that genuinely plays differently from standard payline games.
FAQs
Set your bet ($0.10-$100), then spin the 5×4 grid with 14 fixed paylines. Land 3+ matching symbols left to right to win. Gas Canisters transform symbols into wilds when part of winning combinations—green canisters spread locally, purple canisters convert all low-pays on the entire grid. Wilds receive multipliers from 2x-200x that add together on shared paylines. Collect 3-5 FS scatters to trigger free spins features.
Default RTP is 96.32%, but operators can configure it to 94.30%, 92.24%, or 86.26%—always verify before playing. Volatility is medium (3/5) with 20.7% hit frequency (about 1 in 5 spins wins). This creates more frequent wins than high-volatility slots but with modest base payouts. The 10,000x max win potential comes from multiplier stacking rather than base symbol values.
