On the sudoku site the puzzles there show either 3 or 4 numbers
in each sub grid. So your only possiblity is 1 or 2 as smaller, not
much of a range. 1 you could eliminate as allowing many solutions
so the idea is to figure out if 2 in each grid could be set up
to have only one solution, I think not. I think with 2 in each grid you
have many more solutions so it looks to me like 3 and 4 are the
minimum already.

OK I doubt this will work. But there is a 17 number setup with a unique solution. No 16 numbers setups with unique solutions have been discovered but they haven't been shown not to exist.
EDIT: Well it worked kind of.

Oh, you meant 17 was the answer to the Soduku thing, I was thinking of Life, the Universe, and Everything.
nevermind....😀
That's how I got to the answer to the Soduku thing
42 = 12 + 13 + X
X = 17

site had 6 3's and 3 4's (30) It just seemed to allow more
solutions if you had less occupied squares.
So the key is the *position* in the squares.
