When I load this puzzle Sudoku Cue is aware that something is wrong and surrenders. (There are 5 solutions.)
Code: Select all
. . . | . . 1 | . . .
. . 8 | . 4 . | 2 . .
. 4 . | 8 . 5 | . 3 .
---------------------
1 . 5 | . . . | 6 . .
. 2 . | . . . | . 4 .
. . 6 | . . . | 5 . 9
---------------------
. 5 . | 4 . 6 | . 8 .
. . 3 | . 2 . | 7 . .
. . . | 1 . . | . . .
If I now click on solve it decides the puzzle is easy and can be solved with uniqueness.
