Why my chess puzzle rating dropped a lot out of no where?

Hello everybody, i have come to discuss the sudden puzzle rating drop in almost every chess.com account.

Suddenly between 8 October-10 October (today) in almost every account there was a rating drop between 500-more than 1000. I saw my rating drop today i was at 2030 elo whith a streak of 11 and i open my account and i see 1500 elo even though i didnt got a single puzzle incorrect. I panicked and started looking on internet i saw there are not much videos about this topic but there was a forum about this topic. I saw people complaining about their rating drop but then i noticed all of their rating drop were between 8-10 October then i looked my freinds's account and i saw the same thing i verified the same thing for random accounts and top players like Hikaru it was the same rating drop between 8-10 October. After this research i have three possibilities:

1: Chess.com got hacked

it is possible that chess.com got hacked but it's possibilities of getting hacked are pretty low and also why would someone lower other people's puzzle rating.

2: Chess.com might be testing a new program for puzzle but maybe it caused a glitch and lowered everyone's rating.

3: The puzzle system got corrupt and did this thing.

Not much people have noticed yet so pls tell this to your friends and people you know who play chess bcs even my friends didn't know when i told them about this. And talk about this problem on internet so that more people know and chess streamers talk about this problem make it an important topic on internet to discuss on. We need to send complaints to chess.com. We need to do these things if we want our rating.

Thanks

New Puzzle ratings on Chess.com - October 2025

You may have noticed your Puzzle rating looks very different, and probably lower, than before. Don’t worry, this isn’t just a downgrade within the old system. We’ve introduced an entirely new rating system and re-rated every player and puzzle on Chess.com, processing about 17 billion attempts to ensure accuracy.

New Puzzles rating on Chess.com

The old system caused major rating inflation, which made ratings less meaningful and harder to connect with actual playing or tactical strength. It also prevented us from accurately rating puzzles, which limited our ability to serve you puzzles that were the right level of challenging. For example, in the old system:

Every solved puzzle gave at least 5 points.

Partial credit was awarded for incomplete solutions.

Other features added points just for participation.

These changes made the system 'too generous,' leading to inflated ratings for both players and puzzles.

I found the chess. Com article explaining this.

YES ME TOOO

this happened to me too I went from 3000 to 1800 what the f is going on
