Logic Masters Deutschland e.V.

A Scojo Setting Saturday prompt submission for turning normal outside clues into diagonal ones. Thanks to bootenks and gdc for testing and feedback.

Rules:

• Normal sudoku rules apply.
• Skyscrapers: Clues outside the grid indicate how many digits are 'seen' looking into the grid along the indicated diagonal. Digits are visible when they are larger than all digits before them.
• Grid borders extend the sight line of the clues at a 90° angle, and can be extended multiple times, For example the 3 clue above r1c4 sees along the indicated diagonal from r1c3 to r3c1, then continues along a new diagonal from r3c1 to r9c7, a third diagonal from r9c7 to r7c9, and finally the fourth diagonal from r7c9 to r1c3.

Below is an example of how a skyscraper clue would work. The seen digits from the clues perspective are the circled 3, 4 and 5

All feedback (positive or critical) appreciated!
