Hello.

Community puzzle ‘Mini sudoku solver’ by nicola is bugged. For third test it has more than one solution.

Author’s solutions is

4132
2314
3421
1243

My program gave other solution:

1243
2314
3421
4132

Both solutions are right, but my own causes ‘Failure’.
Please fix this.

P.S. Sorry for my poor english.

Hi,

Actually your solution is incorrect. It’s good for the rows and columns, but not the corners: each 2×2 corner square must also contain all the digits 1 to 4.
