Many cells are shaded. A cell is shaded if its digit indicates the minimum orthogonal distance to a circle.
A digit on a small arrow indicates the distance to a shaded cell in that direction. If multiple shaded cells are in that direction, the arrow may indicate the distance to any of them.
Digits along a large arrow sum to the digit in the attached circle.
Two cells connected by a red line contain opposite parities.
