# Recreational math

Where can I post problems and solutions with no commitment to formal mathematics?

Some of the problems I do I do not find equal on the internet, like some variants of sacks spiral, problems of counting involving geometry or circular sequences as in the collatz conjecture, they apparently have no good application. How do I judge if they are interesting enough to be posted somewhere as recreational math?

If this is not the right place for this question, please tell me where to ask.

Math.se has a tag recreational-mathematics. See HERE for the 4,000 questions with that tag. Perhaps looking at those, in particular the ones that were upvoted and answered, will give you some idea about what is acceptable in math.se.
