## Parity

### Parity

For this week's contest, the Parity puzzle doesn't seem to be solvable. As seen in the second column from the left, the first row cannot be 6 as 9 should be surrounded by odd numbers, 6 can't be in the 5th row as there is a 6 in that square, and 6 can't be in the 7th row as 3 has to be surrounded by odd numbers, so that leaves 6 in the 9th row, however it should be surrounded by even numbers, but 5 is right next to it

Hi Lowsuann

All the orthogonal neighbors of the colored cells have the same parity (which may be different from the colored one). Non-colored cells CANNOT have all orthogonal neighbors of the same parity.
