- Shading
The brief
Normal sudoku rules apply.
Shade cells using two colours such that each colour forms an orthogonally connected region, and no 2x2 area is a single colour.
Digits in caged cells indicate how many cells of the same colour are seen orthogonally from that position, including itself. The other colour blocks vision.
The digit in a cell with an arrow must match the count of cells of the opposite colour in the given direction. Each arrow is considered separately.
