This puzzle is taken from my new book "Fog Of War : Vol # 1".
This puzzle was also covered by Bremster on his Youtube channel. You can watch the video

Rules: Classic Sudoku rules apply.
The grid is partially covered in fog. Placing correct digits will clear the fog
from the digit's surrounding cells.
Adjacent digits along each green line have a difference of at least 5.
Adjacent digits along each orange line have a difference of at least 4.
Digits along each grey line have to be different and must form an
arithmetic sequence in the correct order.
A black dot between two digits means one of them is double the other. A
white dot between two digits means they are consecutive. Not all possible
black and white dots are necessarily given.
