Do you have a 17-clue Sudoku puzzle that might be new? Or is it just an isomorphic copy of one of the known ones?
NOTE: (December 29, 2010): Due to various problems including losing part of the database, some of the data regarding the last 1500 puzzles has been lost. The puzzles themselves are intact, but the date of discovery is incorrect and who found them is no longer known. The numbering (that is, the ID#) of these last 1500 or so is also slightly different.
Enter your puzzle here and we'll let you know if it's already in the database, or if it's a new one.
