3 4 7 | 5 8 2 | 9 1 6 ? can be either 2 or 4 and if flipped (but lined
9 5 1 | 6 3 7 | ? 8 ? right) both options work
6 8 2 | 4 1 9 | 5 7 3
AND
5 3 9 | 2 4 1 | 8 6 7
4 2 8 | 9 7 6 | 1 3 5 " can be either 6 or 7 and again if placed properly
7 1 6 | 8 5 3 | ? 9 ? in the rows either position will work

2 9 4 | 7 6 8 | 3 5 1
1 " 5 | 3 9 4 | " 2 8
8 " 3 | 1 2 5 | " 4 9

True, what you posted,
Code: Select all
`347  582  916951  637  -8-682  419  573539  241  867428  976  135716  853  -9-294  768  3511-5  394  -288-3  125  -49`

has 4 solutions and is thus invalid.

But surely that was not the original puzzle youi found in some newspaper.

Please post the original so we can determine what happened. We can often supply missing clues that will make the puzzle unique and symmetric.
