How these estimates are made

IdleOn

IdleOn is estimated to have 41k – 140k players a day. Around 500k – 1m accounts have played it in total. The range is anchored on Steam’s official concurrent-player and review counts, then converted to daily actives and accounts — so it covers the Steam player base and will under-count a game played mostly through its own launcher or on console.
