The Sky is the Index

(Published on 18. September 2026, 16:53 by PrissyP)

Rules

Sudoku:

Normal Sudoku rules apply.

Index Lines:

The value in the Nth cell along a line (starting from the diamond) indicates the position along the line where the value N appears.

For example, if a diamond cell has a value 3, the third cell along that line must have a value 1.

Skyscrapers:

Each cell represents a ‘skyscraper’ whose height is the digit in that cell. Taller skyscrapers obscure the view of smaller ones. Clues outside the grid tell how many skyscrapers are visible looking across the row or column from the direction of the clue.
