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.

X's and V's lie on the border between the two regions. Additionally, X's separate digits that sum to 10, and V's separate digits that sum to 5. Not all such X's and V's are necessarily shown.
