Why?
If I have a complete grid, I can remove the top left number, and that's a puzzle.
Or, I can remove the bottom right number, and that's another puzzle.
So, one unique grid can be the solution to multiple puzzles.

- rpadovani 4y agoYap, and that has been refuted: > No, in Sudoku, the constraint of a "unique solution" is that a valid puzzle (i.e. an incomplete grid) must only have one correct way of being filled in without violating the rules. My answer is to the answer to the above comment: > Then the maximum number of solveable puzzles must be the maximum number of unique grids
