Puzzle cheaters
Who cares if someone cheats on puzzles? Doesn't affect anyone else.
Spoken like someone who doesn't care about competitive puzzles

We've got people rated 60 000 and more in puzzle, and 600+ in puzzle rush. They're obviously cheating, how are they not banned?
At the higher puzzle ratings, there are less puzzles that super tough. This means that some players just try memorizing the puzzles. It isn't cheating. Others just spend super long calculating and double checking before moving. They may increase their puzzle rating super high by doing this, but it doesn't really help them much as a real game won't let them think about a certain position for hours.
As others have mentioned, discussion of cheating is not allowed in the general forums. This includes puzzles. Create this forum thread in this club instead:
