Puzzle Rating Change

so my friend ( previous 1800) gets put to 1750 but me (3100) gets put to 1500? why did he get -100 and I get - 1500? BS punishing players for actually committing to a practice.

Thanks chess.com now I don't care about premium and I don't want to use your website for making me feel like 50 hours was worth nothing.

Same, I feel woebegone after seeing my puzzle rating points plummet from 2100+ to 1500!! :( I have evidence that it was 2100+ points; it was on my profile, in my 'Awards' section, specifically under 'Achievements', and it was given to me this month.

Same here, 2012 to 1460. What is even going on?

It makes no sense that the score when you get it wrong is double that when you get the solution right.

FerGue52 - I think it is because of the rating of each puzzle. The easier it is considered to be the more you can risk losing, and surely it must be in relationship to your rating at the time.

If that were the case, then the opposite should happen at the most difficult level: if I win +12, if I lose -6.
I repeat, there's no correct logic, and this even before!

Each member's unique puzzle history was put through the new rating algorithm with each puzzle's updated rating. The performance on those puzzles is what decided what the rating was

The number of points gained/lost depends on the puzzle rating compared to your rating.

If you're on Standard difficulty, which is the default, the puzzle ratings are lower than your rating, on average, so you'll gain fewer points on a success and lose more on a failure. It works the same as game ratings.

Try changing to Hard or Extra Hard. You'll gain more points and lose fewer but will likely get fewer puzzles correct and the overall rating changes will be similar.

Yet, logic is logic!
1st If I do the standard level:
If I get it wrong, I lose a lot of points because it was easy;
If I guess right, I get a few points because it's easy!

OK, and everyone here has figured it out!
So strictly speaking, logically =

3rd When I do the extra difficult level:
If I guess right, I get a lot of points;
If I get it wrong, I lose a few, or at least the same number, because it's difficult!
Instead, in the extra difficult level, when I guess right, I get +7+9;
When I get it wrong, -12.
It doesn't make sense!

I don't think I have lost 12 on getting one wrong on Extra Hard. in my last 25 it was 6-8. I may have had 9 but 12 would only happen if you got, and failed, a puzzle at least 100 lower rated.

In looking at your history, the -12 was 200 points lower rated

Let's get this straight once and for all!
- Extra difficult quiz
The value of the points lost cannot be greater than the points won.
Clear?

Yes, they can, if you fail on a puzzle that is lower rated. It's the exact same as if you lost a game against a player lower rated. The overall point gains/loss will be very similar in all three categories, it's just that the average rating of puzzles will be different, so it's expected you'll get fewer correct as you work your way up the difficulty levels

But do you read what I write or do you just continue your reasoning without listening?
I'm not talking about the lower two levels, I'm talking about the EXTRA DIFFICULT level.

Correct +7 points
Incorrect -9 points

It works the same, regardless of level. The rating algorithm is not changed with the Difficulty setting.

If you fail a much lower rated puzzle, you'll lose more points, regardless of your difficulty setting. What matters is the point difference between your rating and the puzzle rating.

Difficulty changed the selection algorithm.

• On Standard, the average rating of puzzles will be lower than your current puzzle rating. Most will be low enough that you don't get many points on a success and will lose a lot more on a failure.
• On Extra Hard most puzzles will be closer to your rating, with some above and some below, and the rating changes will be in a tighter range. You can still get much lower rated puzzles and lose more in a failure though.
• Hard is somewhere in the middle of those.

It's actually awesome that I can now get +7+8 points for a success and lose -7-8 points per a failure in a stable way.

Those +5 -17 were highly frustrating for me because once slightly tilted I used to fall into a positive tilt feedback loop easily - especially considering the game only gave good points back for very fast solutions, kinda forcing my tilted brain not to think much.

The change feels nice, thanks for the devs.

@Martin_Stahl

So the error lies precisely in this basic concept of yours:
"Most Extra Hard puzzles will be closer to your rating, with some above and some below, and the rating changes will be in a tighter range. You can still get much lower-rated puzzles and lose more in a failure, though."
Extra Hard puzzles should only have scores equal to or higher than mine,
and the same should be true for the other levels.

The puzzle score must be equal to or higher than mine, never lower!

That's not the way it works.

There are plans for a harder level, which might work like that, or close to it. Though I haven't heard any details and it might be a while before it's released so there's sufficient testing to make sure it doesn't cause inflation. I also guess that when it's available, most members will miss a lot more than they get right.

the lichess algorithm works differently
