How these estimates are made

Agar.io

Agar.io is estimated to have 43 – 20k players a day. Around 19k – 2m accounts have played it in total. No Steam data is published for this game, so the range is modelled from the size of its Discord, Reddit, Twitch, YouTube and app-store communities. It is a rough band rather than a measurement.

Rules of Survival

Rules of Survival is estimated to have 3 – 9 players a day. Around 110k – 280k 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.
