Does it keep earning while I'm away?

It does. Your helpers earn Iron passively, and you'll collect capped offline earnings when you return.

How do I earn faster?

Buy more buildings, purchase Boosts, and ascend to bank Brass Cogs — each one permanently multiplies your output.

What does ascending (prestige) do?

Ascending resets your Iron and buildings but grants Brass Cogs that boost every future run, so you grow much faster.

Can I play on my phone?

Yes, it's fully touch-friendly and works on phones, tablets and desktops with one-tap controls.

Is my progress saved?

Your progress saves automatically in your browser, so you can close the tab and pick up right where you left off.

👆 Steam Foundry

📖 View Web Story

Steam Foundry drops you into a clanking Victorian foundry and dares you to build the most mechanical iron empire on the web. It all starts with a single tap on the furnace: each press mints a little Iron, and Stoke the boilers and pour molten iron into clockwork machinery.Spend what you earn to hire helpers like Little Stokers, Busy Stokers and eventually Cosmic Stokers. They keep working even after you stop tapping, so your Iron ticks up every single second — close the tab and you'll come back to a tidy pile of offline earnings. Stack boosts such as the "furnace Festival" to multiply everything, then chase achievements that hand you a permanent edge.When growth slows, ascend to bank Brass Cogs: each one you hold quietly supercharges all future runs, turning a slow start into an avalanche. It is built to play itself while you watch the counters climb, and it runs instantly in your browser on phone, tablet or desktop — no download, no sign-up. Fire up Steam Foundry, find your rhythm, and see how big an empire iron can buy.
