Full Rules & Information About the Steamrunners Online Slot

Wild Gas Canisters spread horizontally and vertically and transform adjacent low-paying symbols into Wilds with random multipliers between 2x and 200x.

During the free spins, Wilds with multipliers become sticky and double their value each time they’re affected by a spreading Gas Canister symbol, potentially reaching up to 5,000x.

Depending on your jurisdiction and the casino, Steamrunners’ RTP rate could vary between a minimum of 86.26% and a maximum of 96.32%. Now let’s review the game’s symbols and payouts, so you know what you’re up for.

Steamrunners Bonuses & Features

Steamrunners features not one, not two, but three free spins bonus rounds. 3 FS Scatters unlock the Sky City bonus which awards 8 free spins. Wilds with multipliers are sticky during this and all other bonus rounds.

Wild multipliers double every time they are hit by a spreading Gas Canister symbol, reaching a maximum of 5,000x. The Gaslight District bonus is unlocked by 4 FS Scatters and awards 10 free spins. At least one Wild is present on the grid during this game.

Finally, landing 5 FS Scatters in the base game will unlock the Court of High Steam Hidden Epic bonus. You get 10 free spins with 1 Gas Canister on each of them. If you land 2 or 3 Scatters during any of the bonus rounds, you’ll get 2 or 4 extra spins, respectively.

Steamrunners by Hacksaw Gaming has a Bonus Buy menu where you can buy one of the following features:

• BonusHunt FeatureSpins – They cost 3x your bet and make it 5 times more likely to trigger a bonus game.
• SmokeShow FeatureSpins – They cost 50x your bet and guarantee 1 Gas Canister lands on the reels.
• Sky City – You can unlock the Sky City bonus game for 80x your current bet.

Similar Games & Best Alternatives

If you’re looking to explore other Steampunk-themed slots, then we recommend you try Steam Tower by NetEnt. The game has a high RTP rate of 97.04% and a hit frequency of 32.81%.

Another recent Hacksaw Gaming slot, The Count, comes with a pretty similar setup and features. One thing that’s different is its theme – vampires. Instead of Wild Gas Canisters, you get Wild Bat and Expanding Bloody Wilds. And instead of the Sky City bonus, you get Bat to the Bone.

Buckle Up for the Steamrunners Adventure

Steamrunners by Hacksaw Gaming will appeal to many kinds of players. It offers flexible betting limits ($0.10 – $100), three bonus rounds, and a Bonus Buy feature. The slot’s RTP rate could be lower at some US slot casinos, which might be a bit disappointing.
