How does a Chess Puzzle get its rating
Sort:
I have to imagine puzzles are rated by how many people get them right or wrong at various puzzle ratings. But sometimes I wonder… a lot of times I’ll see puzzles at 2600+ that are insanely obvious one-move solutions; and I’ll wonder ‘how did that one get in here??’

When a Chess puzzle doesn't have an ELO-rating yet, does that mean it gets the estimated ELO-rating of the first to solve it? Or do you have it determined by an engine like Stockfish somehow? I just solved one with a surprisingly high ELO-rating, which is nice, but I'm not too sure how accurate the puzzle ELO-rating was.
I believe a general start rating is assigned and after each solve the rating of the puzzle changes based on being solved or failed. It's treated as a game against a player using that player's puzzle rating.
The puzzles stay in a pending state for a while.
