How to "hack" your rating

Bruh try adding this...
<delete_function>. hack.account.player.it=True.. (spanPPP)?/Lifetime(start
print("you are now a staff! please notice this is fake just gives you pawn only viewable by you")
import,,,,,,,,*short*(cook)
start(function)
enable[greenpawn]

I will show you how to "hack" your rating. It's not really hacking, though.
First, go to a page with your rating number. For example, this link: https://www.chess.com/stats/live?type=daily (Stats)
Now, right click the rating number and click "inspect element"
Right click the highlited code and click "Edit as HTML". Then, change the rating (Any number).
You should get this by then.
Then, click the "x" button to close inspect.
You should get this by then. Troll your friends!
This only temporarily lasts. Once you leave the page, it becomes it's usual rating.

i found a real way to hack your puzzel rating, and everyone does it even hikaru NakamurA, the one way to hack it, is by doing the puzzels everyday and practice until you remember all stuff

@Azathot0 - yea, that hack works. Slowly. Very very slowly... My biggest "hack" in puzzles is I try to be REALLY sure I have the best move before making it. If I only get 1 point, it's better than losing 10. I will indeed close the app on the phone & come back later if I can't figure it out. I get a LOT of little 1 point wins but the puzzles aren't so much about rating as it is about a safe practice area that won't hurt my real rating.

yeah that's what i do, but sometimes i be risky, like when you know there is a forced mate in 7 and the puzzels just want you to have better positions, with the rooks knight and bishop, or they would want you to trade queens when you know, there is another way to steal that queen from the opponent, but the puzzels is like
Chess:com puzzels: " Ok Light Yagami, we know this also works, but im sorry, we have to deduct 15 points because you did not do the puzzel the way we wanted you to do, the move you made in the puzzel was indeed correct, but because we only want it in one way, you lose points" that's how i feel chess.com puzzels are like

it kinda does for puzzels, because the harder the puzzels the higher the rating, and the more challenge you will have and learn.

for a regular game of chess, rating doesn't matter, it only matters when your opponent is 2000+ and your 3 to 1000+ rating, then it matters
thx
