- Normal sudoku rules apply.
- Global Indexing: Cells in the same relative position with respect to their box form an indexed set: if the cell in position P for box A has the digit B, then the cell in position P for box B must have the digit A.
- Skyscraper arrows: The digit on an arrow indicates the number of digits seen in that direction, for that effect, digits block any lower or equal digit from being seen.

Definitely learned things about indexing.

It seemed difficult at first, but once I got the hang of thinking in terms of global indexing, it was a pretty quick solve. 2*

Got the first four digits in relatively short order, but then was sat on them for nearly two hours slowly incrementing logic all across the board until it finally reached critical mass. I found it very difficult but quite enjoyable. Thank you.

Very very hard break in, but gets easier along the way. Rich and beautiful.
The indexing part is manageable, but the skyscrapers are not sunflowers.
