Cross the Sums
(Eingestellt am 13. März 2023, 12:56 Uhr von abed hawila)
Puzzle rules:
1. Normal sudoku rules apply.
2. Japanese Sum: shade some cells so that the outside clues indicate the sums of the contiguous shaded cells in that row or column. A number indicates the sum of a complete contiguous block. A question mark (?) indicates that a contiguous block sum to a single-digit number and a double question mark (??) indicates that a contiguous block sums to a double-digit number. An asterisk implies that any number of blocks may exist, including zero. The clues are provided in the correct order (left-to-right, or top-to-bottom), and there is at least one unshaded cell between each pair of clued blocks.
3. Cross the Streams: the shaded cells form a single orthogonally connected group. No 2×2 area within the grid can be totally shaded.
You can play the puzzle online using the following link: Penpa+
You can check the following 6x6 example to visualize how the rules work. Also, you can give it a try here
Hope you have fun!
Lösungscode: Row 7 (9 digits from left to right) followed by the length in cells of each of the shaded segments from top to bottom for column 3. (for example: in the 6x6 puzzle, the length of shaded segments in column 4 is: 211)

Very nice, abed! I like how much CtS logic you actually managed to fit into the puzzle.

A really gorgeous and satisfying puzzle! It’s interesting how the connection of shaded cells can lead to lots of interesting and cool logic :)
[also the 2 stars combo in a column was quite funny there x)]
