Are Chess.com's puzzles getting harder?

In the same time period that my lichess puzzles went from 1800 to 2100, my chess.com dropped from 2500 to 2300

Is chess.com's puzzles getting harder?

They may be yeah. I recently tried some puzzles after a long break from them, and there were a couple I wouldn't have been able to solve in a year. Definitely felt like they were harder than a while ago, whereas in my games I don't feel like I've become worse, but rather the opposite.

I'm sorry

I think they have got harder since around March 2023. In Puzzle Rush Survival I would usually get around 30 using my 3 lives (my record is 36). Now I struggle to get to 25. My rating has gone up however so I don't think I'm getting worse 😃 I'm 1100.

I don't think Puzzle Rush puzzles are getting harder (my score is gradually increasing on all modes), but the 2000-2200 regular puzzles I was previously solving are now straight up crazy. Like, there's no way. At all. Some of them don't even make sense to me after computer analysis - like line "A" is wrong, materially equal to line "B", which is the correct solution, and there are no tactics following, just a whole game there waiting that the CPU knows you're "winning". These guys typically have 20%, 30% pass rates (for many of these seems actually pretty suspiciously high, I digress) and the ratings are never fixed. Should they be normalized to 50% at-rating? Or some %, pick a number....
Meanwhile, the daily have gone the other way, most are all now boring snoozers. =/
I wish these things were normalized, tested, or otherwise calibrated better.

While puzzle ratings can vary across platforms due to differences in puzzle selection and user base, Chess.com may be emphasizing more complex or less straightforward puzzles lately. Additionally, your personal progress and skill level might affect how you perceive the puzzles' difficulty. Have you considered comparing specific puzzle types or themes on both sites to see if there are consistent trends? And can anyone help me regarding sending large files to my friend who is in another country? I am thinking about using Filemail but I haven't used it before. It is my first time and that is why I want to know if it is worth using it. I will be thankful to you, if anyone over here helped me out.

Yep—something's definitely changed the past few weeks... As someone who's played 3 minute puzzle rush daily for a few years now, there's a noticeable increase in difficulty/complexity, with some completely new 'tactical styles' or ideas having been thrown into the earlier lot of puzzles.

I was asking the same question. I’m not doing puzzle rush lately, so I don’t know about that. But with standard rated puzzles I was above 2500 at my normal days, around 2400 at my really bad days and above 2600 at my best. The past couple of days, maybe over a week, I’ve been dropping. I struggle at 2100-2200 now and it feels too hard to get over it. And I don’t think it has anything to do with concentration or stuff like that, I’m playing everyday and my elo on rapid, blitz and also daily is all time high now.

I haven't noticed any changes
