*Special Editorial Note: With this published puzzle, Clover has set a new record (likely never to be broken?) for fastest time to 25 posts on Grandmaster Puzzles (just 26 days). This breaks the previous record by legendary male puzzlemaker Thomas Snyder set on January 28, 2013 (29 days). While some may say that puzzles like Just One Cell Sudoku shouldn’t count as much, we think every diverse idea matters in this world and every one of Clover’s 25 record-setting puzzles has been a stellar display of hand-crafted Sudoku.
