are sudoku puzzles np hard?

Well, in principle you just start with a full grid and remove a bunch of numbers. Of course, you need your remaining numbers to give a unique solution... but that's not necessarily as difficult as running through the puzzle to check. It would depend in part on how many numbers you take out on the grid.
