A Birthday Secret
(Published on 2. January 2025, 20:10 by starwarigami)
A gift for you on my birthday!
Normal Sudoku rules apply.
Digits may not repeat on the blue diagonal line.
Digits outside the grid marked with an arrow show the sum of the digits on the indicated diagonal.
Digits outside the grid without an arrow are skyscraper clues if it is possible to be one, and sandwich sums otherwise.
Skyscraper clues show the number of digits visible from that location in the indicated row or column, where larger digits hide smaller digits from sight.
Sandwich clues show the sum of the digits between the 1 and the 9 in the indicated row or column.
