Wikipedia:Articles for deletion/XKnight Game
After reading your argument, it was your own statement of ''How can I include a reliable source if it does not exist?'' that made me decide against keeping this article.  I understand your point and I do think this is a valid, well-thought-out puzzle format.  As a programmer and a bit of a logic-puzzle-geek myself, I personally think this idea is great, and would love to see more of them.  Inclusion in Wikipedia, however, is based on |notability guidelines, which are not dependant on personal attitudes and interests.  They require that reliable outside sources are used for verification and to show that subjects are of interest.  If, for instance, a published newspaper offered these puzzles in the same way they offer crosswords or sudoku, or a significant puzzle/math magazine or website writes an article about it, then it would meet Wikipedia's guidelines.  This type of puzzle must be promoted to puzzle fans and the media before it can be considered for Wikipedia
