Hello,
STRIPES: Each digit in the yellow cell must not be larger than the number of yellow cells in its 3x3 region.
PARITY: 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.
