Exclusive Internal Skyscraper Loop
(Eingestellt am 28. Juni 2025, 01:40 Uhr von yttrio)
Rules:
Normal Sudoku rules apply.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
Cells with arrow clues are internal skyscraper clues. Each cell in the grid represents a skyscraper with a height equal to its value. A digit in a clued cell gives the number of skyscrapers visible in the indicated direction (not including the cell itself), where every skyscraper blocks the view of all skyscrapers with the same or lower height behind it.
All cells seen as skyscrapers from a clued cell must be on the loop. All cells in the direction of the clue not seen as skyscrapers must not be on the loop.
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Play the example 6x6 in SudokuPad.
Lösungscode: Digits on the loop in row 6 (left to right) followed by digits on the loop in column 7 (top to bottom)

I’ve recently made the move from two star puzzles to three stars and this was my Everest! Four restarts, many hours, but so worth it in the end

Terrific puzzle, the bottom part of the loop was very tricky for me :D

It's amazing that there is enough information in this grid not only to solve, but to solve so smoothly. But it is a yttrio puzzle, so I don't know why I'm acting all surprised.
