True, what you posted,

Code: Select all

347  582  916
951  637  -8-
682  419  573

539  241  867
428  976  135
716  853  -9-

294  768  351
1-5  394  -28
8-3  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.
