Terraforming Mars

The taming of the Red Planet has begun! Corporations are competing to transform Mars into a habitable planet by spending vast resources and using innovative technology to raise temperature, create a breathable atmosphere, and make oceans of water. As terraforming progresses, more and more people will immigrate from Earth to live on the Red Planet.

Player estimates

Nobody publishes how many people play Terraforming Mars, so these figures are modelled from the public counts on Google Play, App Store, Steam, Twitch. Each count stands in a roughly known ratio to a population — one Play rating per ~45 players, one Steam review per ~35 owners — and the estimates below combine those readings, weighted by how much each source can be trusted to speak for the whole game. Read the range as the answer and the headline as its middle.

Frequently asked questions

How many people play Terraforming Mars?

We estimate that about 450,000 people have played Terraforming Mars — plausibly between 220K and 900K. Around 22,000 of them play on a given day, in a range of 2.2K and 130K. Both figures are modelled from public counts on Google Play, App Store, Steam and Twitch rather than published by the developer, so read them as a scale rather than as a headcount.

Is Terraforming Mars still active?

Yes. Terraforming Mars is holding steady — it measured within a percent of where it was a week ago. We recheck every source daily, and the charts on this page show each platform's readings over time.

How are the Terraforming Mars player estimates worked out?

Nobody publishes player counts for mobile games, so we infer them. Each public count we can read is converted into a population using a documented ratio — roughly one Google Play rating per 45 people who played, one Steam review per 35 owners, one Discord member per 40 players — and the live counts (Steam concurrents, members online, Twitch viewers) are converted the same way into a daily figure. Those separate estimates are then averaged in proportion to how much each source can be trusted, which is why sources that disagree widen the published range instead of cancelling out. This page is built on 2 readings taken since August 8, 2026.
