There are additional changes in the works and should be rolling out relatively soon.
Here's some information from staff about it.
We are currently working on a significant overhaul of our puzzle difficulty system and puzzle ratings. Over time, the current puzzle rating algorithm created highly inflated puzzle ratings for our members — and consequent inaccurate estimates of a puzzle difficulty. As we roll out our new system, you may see some inconsistencies in your puzzle stats, and rating changes from puzzles solved and missed may be greater than in the past.
We ask you to wait with us just a bit longer! Since in the coming weeks we will be publishing an entirely new rating system for puzzles for all members. We’re confident it will be a major steps towards our ultimate goals:
- Provide a more meaningful rating which correlates more closely to player’s Blitz and Rapid ratings.
- Serve puzzles better suited for each player’s level.
- Offer options to member who are looking for different puzzle-solving experiences.
I am aware there are other threads about this but I want more topics with this title. The current matchmaking for puzzles is ridiculously easy for players 2500+ under the old puzzle matchmaking ratings.
Although I have been 3000+ in puzzles, all I get now are lowball 2200 level puzzles that are too easy. Importantly, I HAVE set my puzzles to Extra Hard difficulty and it makes no difference.
This new matchmaking is causing Chess.com to lose money because players like me that subscribe to play hard and fair puzzles are now just facing easy puzzles and we're stopping our subscriptions.
