What Is The Least Number Of Numbers Needed To Be Given In Order To Determine A Sudoku Puzzle?
I mean
What is the least number of numbers that is needed to be given in a sudoku puzzle in order to determine exactly one solution.
=p
Explain your answer please lol.
Going for "least needed", 17 is the least that has the potential to define a unique 9x9 fill.
Going for "most needed", it should be possible to have a 2x2 that can flip either way, so that 77 squares could be filled and still have a duplicate solve, so 78 would be the magic number to force a unique solution.
I'm not sure given your question which of these answers you are looking for.

The least amount of given numbers to limit the correct answers to only one solution depends on the size of the puzzle.
In a standard 3 x 3 arrangement (total of 9 puzzle blocks) you would need to have 6 given.
