Rules
Normal sudoku rules apply.
Shade some cells so that all shaded cells are orthogonally connected, and all unshaded cells are orthogonally connected. No 2x2 area may be completely shaded or unshaded.
The shading splits each line into segments which sum to 10. Digits may repeat within a segment.
Solution code: Column 5
