This tag is for questions about the name or nature of a specific puzzle, given as much descriptive information about it as the asker possesses. For challenge questions where the asker knows the puzzle type and gives cryptic clues about it, use the [reverse-puzzling] tag instead.

Use this tag when you're not asking about how to solve a puzzle, but asking about what the puzzle is called or how it works, given its description. Try to include as much detail as possible to aid identification, including pictures if applicable.

Note that questions with this tag, unlike most on Puzzling SE, are intended to be asked by people who don't already know the answer. If you're writing a challenge question in which you do know the name and type of the puzzle and are leaving cryptic clues about its nature for others to solve, then you should use the tag instead.
