It's fine to propose question drives, challenges, and contests -- on meta. Embedding all that into a question on main is problematic, and that will have to be edited out before the question can be reopened.
This particular game ("golf"?) proposal strikes me as needing some work. It seems to encourage brainstorming on a discussion forum. Stack Exchange sites are not for free-form brainstorming, and they are not discussion fora. Chat is a great venue for that and our site's chat room is frequently quite active, so please avail yourself of the opportunities there. If you (meaning the author of the question on main) want to pursue the "golf" proposal, please make a new post on meta explaining the idea, how it would work, and how it fits the Stack Exchange model. The fewer established principles you violate, the better the odds are of it working.
Questions are meant to be useful for the long-term. Any limitation in a question like announcing a time period during which answers are welcome runs afoul of this. The asker of a question is of course free to share any constraints he himself is operating under (like "I need to submit a draft in two weeks", but if somebody comes across the question six months later and has a good answer, nothing in the question should discourage him from offering it.
On this specific question, I can't tell what the question actually is. I see it was closed for being off-topic; I would have closed as "unclear what you're asking". My advice to the OP would be to cut all the contest meta stuff and then clarify what remains into a clear question that the community could then reopen.
