I've watched a lot of streamers play it but I don't know if it is a feature or just for streamers.

i saw hikaru do it once

just watch the game (example gatorade vs gfuel) and guess what rating they play at.

also i think this is just for streamers, not a feature since the streamers have like a dev team that updates all the stuff, i believe 

You can play it here http://eloguessr.com/ and do it on your own. or if you want to participate in a content creators elo guesser, send your game through their discord and you normally have to be a sub.

Oh ok I thought it was on chess.com.

Sme

Just got a 4504

Guess the ELO

This is a rated blitz game played on chess.com. The elo difference between the players is at most 200. Guess the average ELO of the game!

Once i got 5000/5000 but i forgot to took screenshot.
