What tag should be used when asking for a solution to a puzzle?

Asking for a solution to a specific puzzle seems to be on topic, but what tag should we use?

is already used for both these types of questions and questions discussing solutions in general.

Also, as per the comment by TheDoctor, there are two kinds of puzzles to solve:

1. Challenges set by a user to other users, and
2. Puzzles that users need help on.

We need to keep in mind that a tag should be as specific as possible (IMHO, is way too general since on a stack about puzzles, there will be a lot of solutions) while at the same time being intuitive enough that a new user will pick the right tag for the question, instead of using an inappropriate one that just looked right.

is, IMO, way too general of a tag. It should probably be split up into:

• : for questions like "How many solutions are there to _____?" or "What is the maximum number of solutions _____ can have?"
• : for questions asking about a specific solution, like "How does this solution work?" or "How can this solution be proven?" (better tag name suggestion would be great)
• : for questions asking about whether a problem is solvable or not

Questions asking for solutions to puzzles don't need a specific tag, because that's just implied as it's the whole point of a Puzzling site. (If this tag is really needed, I'd suggest .)

• In theory, most of our questions are going to be about specific puzzles, and a good portion will be about solutions. I'd avoid those two tags, and stick, with solvability and possible-solutions for solution counts.

• I think "explain-solution" could work for your "solution" tag. May 20 '14 at 22:34

For challenges, I propose , which should be obvious.

For puzzles where a user doesn't know the solution and posts it here in search of one, I propose either or . Possibly one being a synonym of the other. That way, a new user posting a puzzle, will start typing solu or solv and see an appropriate tag.

Referencing the stance on riddles question, we should have a tag, as opposed to . It means the question isn't a guessing game, where the answers seek "something that fits", but give the answer that is considered "officially correct" for given puzzle, citing sources - e.g. the a quote from the author, the jury from a competition where the riddle was presented, or a peer-reviewed paper.

This kind of answer doesn't leave room for doubts about correctness (even if it's incorrect, say, the author made a mistake solving own puzzle; it's still THE answer the author gave!) and while the solution may (always) arouse doubts, the answers can be rated by quality of the sources cited, quality of citations - accuracy as historical references.

Also, requests for solving riddles with this tag should be accepted (while general riddle questions remain strongly questionable).
