When I try to save a questions tagged with calculation-puzzle, logic-puzzle, mechanical-puzzle, twisty-puzzles, or whatever tag containing "-puzzle", I get the error message "The 'puzzle' tag is not allowed".

If this behaviour is intended, could we burninate those tags and provide useful alternatives? If not, did somebody mess up with a regular expression and can we have the problem solved? Thanks!

    $\begingroup$ I'm pretty sure the intent was to forbid puzzle (and puzzles) only. That tag conveys no information whatsoever. Tags with the name of the site are normally forbidden for this reason; here “puzzle” is a variation of “puzzling”. We can take this as an opportunity to decide whether we want to standardize tag names on XXX, XXX-puzzle or XXX-puzzles. $\endgroup$ – Gilles 'SO- stop being evil' Nov 22 '14 at 9:52

I just took a look at our tag blacklist, and it has this:


Turns out that really means (^puzzling)|(puzzles?$), which blacklists any tag that starts with "puzzling" or ends with "puzzle" or "puzzles." Definitely not the intent.

I've poked an employee in chat to fix this for us.
