The 17-hint Sudoku puzzle is considered the hardest Sudoku puzzle because it has the fewest number of starting clues while still having a unique solution. The puzzle has exactly 17 clues, meaning there are only 17 numbers initially filled in the puzzle grid, and the player must use logic and deduction to fill in the rest of the grid.
This makes the 17-hint Sudoku puzzle extremely challenging because there are so few clues to start with. The player must use advanced techniques such as X-wing, Swordfish, XY-wing, and XYZ-wing to solve the puzzle, which requires a high level of skill and patience.
In fact, it has been proven that there is no Sudoku puzzle with fewer than 17 clues that has a unique solution. This was discovered by a group of mathematicians in 2012, who used a supercomputer to check all possible Sudoku grids with 16 or fewer clues and found that none of them had a unique solution. Therefore, the 17-hint Sudoku puzzle is considered the hardest possible Sudoku puzzle.
