Yajikazu Sudoku

(Published on 9. September 2020, 14:21 by Madmahogany)

This puzzle is a combination of a Yajisan-Kazusan puzzle and Sudoku

Yajisan-Kazusan Rules: Shade some cells black, such that the unshaded cells form a single orthogonally connected region. Shaded clue cells have no meaning, and shaded cells cannot be orthogonally adjacent.

Sudoku Rules: Normal sudoku rules apply. Cells with arrows are the Yajisan-Kazusan clues. Valid clues give the sum of all the shaded cells in that direction.

There is this nice introductory puzzle for Yajisan-Kazusan by Carrick22

Here's the Penpa-Link for solving

Solution code: The cells of column 4, followed by row 6 (use O for unshaded and X for shaded, i.e. OOXOOOXOX), followed by the digits of row 4, followed by column 7.
