About Atom Farm
Atom Farm is a free chemistry game you play in your browser. Pick two chemicals, put them in a reactor, and see what you make. Hydrogen and oxygen make water. Sodium and chlorine make table salt. Iron oxide and carbon in the furnace make iron, the way people have made it for thousands of years.
What you do
- Combine atoms and compounds to discover 154 real compounds from 57 elements.
- Pick the right equipment: Beaker, Burner, Furnace, Pressure Vessel, Electrolysis Cell or Arc Chamber.
- Earn XP and coins, level up, and fill your collection book.
What you learn
- Which elements react with each other, and what they make
- Why some reactions need heat, pressure or electricity
- What a catalyst does, with real examples like the Haber process and a car's catalytic converter
- Where chemistry shows up in daily life
Reactions are simplified for now: equations aren't balanced yet.

Visit counts
To see how many people visit, we use Cloudflare Web Analytics. It counts page views and records general facts like the country, the type of device and browser, and which page you came from. It uses no cookies, stores nothing on your device, and does not follow you across visits or other websites. We only see totals, never who you are.
Your saved game
Your progress (your chemicals, coins, XP and level) is saved in your browser's local storage on your own device. It is never sent to us or anyone else. Clearing your browser's data for this site, or uninstalling the app, deletes it for good.
Hosting
The website is hosted by Cloudflare. Like every web host, Cloudflare handles the connection to your device and may keep basic technical logs (such as your IP address) to keep the site secure and working. We don't use these logs to identify or track anyone. See Cloudflare's privacy policy.
The game's fonts and images are stored on our own site. The only other request is the small Cloudflare Web Analytics script that counts the visit.
Children
Atom Farm is made to be safe for students of all ages. Because we collect no personal information from anyone, we collect none from children either.
Changes
If this policy ever changes, we will update this page and the date at the top. If Atom Farm ever starts collecting any information, we will say so here first.
