Tremendous thanks to Jooshy for testing and catching a final error!
-
Standard Sudoku and Kropki (difference and doubling) Dot rules apply.
- Compass Cells (see example below)
-
Each compass cell points to another cell in the given direction (all point East) that contains identical difference and/or doubling dots, with the distance to that copy given by the cell's digit.
In the finished puzzle, each compass cell is identical to its copy (with the possible exception of its contained digit). - Solve Online

COMPASS COPIES PUZZLE EXAMPLE
Notice how each cell that has a compass direction or ?? is identical in its constraints (dots, even/odd marks, arrow-paths/tips/circles, thermometer paths/tips/bulbs, etc.) to its target cell, which is determined by that direction and by the distance given by the digit in that cell.

Took me a long time to understand the rules.
A compass cell will be identical in its constraints (i.e. type and orientation) to the cell it points at. So if A points at B, then B will get all of the kropki dots or even "is the tip of an arrow from the south west" properties. And vice versa A will get all of B's properties.
You're explaining it in the example, but it took way too long to sink in.
After that it was a really smooth puzzle. I will go and try the other puzzles in the series.
