Estimates are modeled, never reported, and made for two stores only: on Steam from public review counts and prices, on Google Play from install counts and typical spend per download. Each is shown as an estimated low–high range — the Google Play range is the widest we publish. Other stores show prices and charts, and ratings where the store publishes them, with no revenue estimate. They are approximations, not official figures.
