Anyway, finding a logical way to solve this one is a real challenge. Using guesswork, french player Yannick Meyapin solved it in 15/20 minutes during a competition. Here is a puzzle which is theoretically even more challenging, with or without guesses : . . . | . . . | . 3 9 . . . | . . 1 | . . 5 . . 3 | . 5 . | 8 . . ------+-------+------ . . 8 | . 9 . | . . 6 . 7 . | . . 2 | . . . 1 . . | 4 . . | . . . ------+-------+------ . . 9 | . 8 . | . 5 . . 2 . | . . . | 6 . . 4 . . | 7 . . | . . .
