Juosan Division

Rules:

1. Standard: Normal sudoku rules apply.

2. Juosan: Some cells must be shaded such that no column contains a run of three or more adjacent shaded cells, and no row contains a run of three or more adjacent unshaded cells.

3. Divided Killer: In each cage, the clue in the top left corner gives either the sum of the unshaded cells, or the sum of the shaded cells. Digits may not repeat in a cage.

Solve on f-puzzles or CTC.
