Partial Eclipse
(Published on 7. August 2024, 21:00 by XeonRisq)
- Partial sudoku rules apply. The digits 1 to 9 must appear once in every region. The digits in each row and column must be unique.
- Cells in gray are NOT part of the sudoku grid.
- Shady Counters : Numbers in gray specify how many digits in grid cells (white cells) repeat in the associated row and column.
- Rooftops (Skyscraper hybrid) : Each digit in the grid represents the height of a building in its cell. Taller buildings obstruct the view of shorter building's rooftops behind them.
- Clues outside the grid give the number of rooftops visible from the vantage point of the building in the first cell in the associated row or column. (not including itself)

Below demonstrates how the Shady Counters constraint works.
The 2 in gray sees 5-4-8 in the row, and 3-4-8-6-1-2 in the column; of which 4 and 8 repeat.
The 3 in gray sees 6-7-9 in the row, and 6-1-2-7-5-9 in the column; of which 6, 7 and 9 repeat.
The 1 in gray sees 3-2-1 in the row, and 5-9-7-3-8-4 in the column; of which 3 repeats.
Solution code: Row 8 followed by Column 6 (15 digits)

Really great idea with the partial sudoku grid and shady counters. Super smooth execution! I was pleasantly surprised by the flow. Easier than 4* imo

Thanks for the detailed feedback, but 4-stars seems pretty fair with the oddity of the ruleset (but difficulty wise, you may be right); and of course, not everyone can be as good a solver as the infamous "wisty"!

That was not as scary as it seems!!!

Thanks for taking a stab at this one, but I did tell you that it was not as difficult as some of the other recent puzzles. Appreciate the solve/feedback.

Appreciate the generous feedback. And rooftops is an interesting twist on skyscrapers constraint, right? Always a joy hearing from you Elliott, appreciate the continued support.
