Proposal: Puzzle and Riddle Challenges
I think it's fairly well accepted that we're encouraging a wide variety of puzzles on this proposal, but how do we quantify an acceptable difficulty of puzzle? This may be related to What quality standards? but consider specifically these two questions:
Both are asking very math-y questions, are either of them puzzles? Furthermore, is a math question dressed up as a puzzle actually a puzzle, or still just a math question? It's worth noting that Math.SE has a clause in its FAQ stating that solving mathematical puzzles is on-topic there.
I'd suggest that we determine puzzle status by the following 2 criteria:
- is it presented as a puzzle?
John has 2 apples and picks 2 more up - how many has he got?satisfies this condition
- is it trivial?
2+2=?can never be a puzzle because it's too simple
