Since early 2006, I have a few contests for overlapping Sudoku variants on my website. If you are interested in these variants, come visit the site and join one or more of the following contests:New puzzles are available weekly and all earlier puzzles can be found in the archives. It will cost you nothing. Since the site is fully supported by donations, it is completely ad-free. When you submit your solutions online, you will be added to the ranking lists.
You can check out any time you like, but you can never leave, unless you have visited the Samurai Rehab Center.
