Puzzles generally get a seed rating and then get modified based on members pass/fails and are treated like game against the member puzzle rating vs the puzzles rating.
I think after a certain number of solved the rating locks but staff will occasionally set a new rating if warranted.
How are the ratings determined for puzzles? I wasn't able to find much info on the forum because too many results were about player ratings not on the puzzles.
Here are two puzzles that for me appeared to be set at the wrong rating.
Are puzzle ratings re-calibrated from time to time or is this just how they are rated? I remember there was an option to give feedback on puzzles, but I don't see that anymore. Or maybe I'm mistaken. Is there any benefit in adding comments on puzzles?
