That mash you have posted does not have a single answer. It is not valid.

This is quite similar and is a valid puzzle.

Code: Select all

7 . .|9 . 2|. . 1
. . .|7 . 5|. . .
. 8 2|1 . 4|6 7 .
-----+-----+-----
3 4 .|. . .|. 2 9
. . .|. 2 .|. . .
1 . .|. . .|. . 8
-----+-----+-----
. . 1|8 . 3|5 . .
. . 7|2 . 9|4 . .
2 . .|. . .|. . 7

It needs an xy wing, and simple stuff, to solve.
