Basic Information 

Steamrunners touched down on November 2025, bringing Hacksaw Gaming’s trademark simplicity and style. It runs on a 5x4 grid with 14 paylines. 

With bets from €0.10 to €100, both budget fliers and first-class rollers can have a smooth ride. 

Theme and Graphics

Steamrunners takes you into a steampunk world, floating above the clouds. The main game screen feels like a mashup between a mechanic’s workshop and an airship deck. 

The grid itself is designed like part of a huge machine, with bolts and valves connecting everything. On the left, a handsome engineer with a robotic arm stands with a smirk on his face. On the right, a small red rocket hovers, ready for takeoff. 

While the grid remains the same, the backdrop, characters, and airship change during the free spins. A woman with an oxygen mask and cameras is seen on the right in the Gaslight District bonus. 

A cinematic piece of music plays in the background, creating the perfect atmosphere for you to spin. 

RTP and Volatility

This slot has a medium volatility, meaning that wins will come quite often to keep your spirits high without draining your tank so fast.

It has a hit rate of 20.7% and its RTP is 96.32%, above the industry’s average. Just note that things may shift slightly if you turn on the Buy Bonus engines.  

Below, we list the possible RTPs:

Symbols and Paytable 

High-value symbols include the telescope, scroll, top hat, gramophone, and googles. The googles are the real MVPs, awarding 5x for five of a kind. 

The usual suspects, A, K, Q, J, and 10 are all worth the same prizes. They award payouts from 0.20x to 1x for payline wins.  

How to Play the Slot

To play Steamrunners, start the game at the casino, set your stakes, and click the 'Spin' button. You can turn on Super Turbo to increase the pace and Autoplay for continuous spins. 

Game Mechanics

Despite the game’s 5x4 board, it only offers 14 paylines. To win, you must match at least 3 symbols on these paylines. Winning combinations are counted from left to right, starting from reel 1. 

Payouts are calculated based on the symbols' worth in the paytable. Though you can have wins on multiple paylines, you can’t have more than one win on a payline. 

Feature Symbols Explained

The slot doesn’t just have pretty symbols; it offers special icons that can blow up things (in a good way). Here, we highlight what to expect:

• Wilds: The regular Wild in the game replaces standard symbols to complete winning combos. It also pays 10x stake for 5 of a kind on a payline. The game also offers the Purple Canister Wild and the Green Canister Wild.  

• FS Scatters: The Scatter triggers the free spins games. 

Slot Name Features and Bonuses

Now, let’s explore all the good stuff that makes this slot really exciting. 

Wild Gas Canisters 

The canisters are the stars of the show. When a Green Canister lands, it spreads and transforms adjacent low-paying symbols into Wilds, boosting your chances of hitting combos. It’ll also continue to spread if other low-value symbols are connected to newly transformed symbols. 

The Purple Gas Canister takes things up a notch. When it lands, low-value symbols are turned into Wilds, if they’ll form part of a win. Sometimes, the transformed Wilds may come with multipliers ranging from 2x to 200x. 

Regular Wild symbols affected by the Purple Gas Canister receive a 2x multiplier. The numerous Wilds plus the multipliers create chances for bigger payouts. 

Sky City

Land three Scatters on the grid to trigger 8 Sky City free spins. During this bonus, all Wilds with multipliers stick to the rules. Their multiplier values are doubled each time they’re affected by a spreading Gas Canister. The maximum multiplier value is 5,000x. 

Hitting 2 or 3 more Scatters awards an additional 2 or 4 spins. 

Court of High Storm

Five Scatters on the reels will take you to the Court of High Storm with 10 free spins. This bonus keeps features from the Gaslight District and also guarantees a Gas Canister symbol on every spin. 

Gaslight District

Four Scatters on the reels welcome you to the Gaslight District with 10 free spins. All the features from the Sky City come along for the ride here, plus you’re guaranteed at least one Wild on the grid on each spin. 

Play Options

You can jump into Steamrunners however you like, for free or for real money. If the 10,000x star prize is tempting to you, you’ll need to put some fuel in the tank. Start by tapping the “Play for real” button at the top of this page, then register and top up your balance. 

We gave the slot a few spins ourselves and had a blast. It wasn’t exactly a mind-blowing experience, but the spreading and multiplier Gas Canisters sure brought some heat. We even hit the Gaslight District bonus a couple of times, which left our wallets smiling in the end.  

Play for Real Money or Try the Demo

Real money play carries real risk, so you should only play with money you can afford to lose. But if luck shines on you, you could hit the jackpot or other massive prizes. Just make sure you manage your bankroll properly if you want to keep the fun going for long.   

For those who prefer a safer flight on the machine, the demo version is perfect for you. You can figure out what the Gas Canister does and how to fly smoothly without spending a single coin. But also, there’s no chance of winning any real reward. 

Demo Features and Mobile Compatibility

Like many Hacksaw slots, Steamrunners offer you €5,000 fun credits in the free trial version. With this, you can spin and try out features with the Bonus Buy to your heart's content. Sadly, whatever you win stays strictly in the fantasy realm. 

Whether you’re going after the multipliers for real profits or just having fun on the reels, the game runs flawlessly on mobile. Thanks to the HTML5 tech used in its development, it fits any screen size. You can use iPhones, Android phones, tablets, or iPads.
