Wikipedia:Articles for deletion/Sudokuthon
per nom - there's a news article about it https://metro.co.uk/2006/10/10/nas-sudokuthon-solution-for-tuesday-261754/ but it looks like it was only for 2006. The Wikipedia article was created around the same time and it looks like it was unknown if this was going to be a yearly event. However,  shows us it was only for 2006 and fails notability
