What is the Sandbox?
This "Sandbox" is a place where Programming Puzzles & Code Golf users can get feedback on prospective challenges they wish to post to the main page. This is useful because writing a clear and fully specified challenge on the first try can be difficult. There is a much better chance of your challenge being well received if you post it in the Sandbox first.
To post to the Sandbox scroll to the bottom of this page and click "Answer This Question". Give the details of your challenge just as you would when actually posting it. Other users will help you improve your challenge by rating and discussing it. When you think your challenge is ready for the public, go ahead and post it, and mark it as posted here.
See the Sandbox FAQ for more information on how to use the Sandbox.
The Sandbox works best if you sort posts by "active".
This is a community-maintained list of the most active Sandbox submissions, sorted by major contest type. Add an entry to the top of this list if you add a new submission or update an old one. If you don't have enough reputation to edit questions you can ask in chat for a higher-rep user to add your submission for you. You may include a [status] indicator and tags to categorize your submission.
If this list grows too long you may remove entries that have been inactive for several days. It's best to remove submissions from this list once they've been posted to the main page.
