9-steps Tutorial: Kropki dots

Here is a tutorial sudoku teaching the kropki dots constraint and aimed at first-timers. It is accessible, though not the easiest puzzle. It is build to showcase some common kropki dot logic you will find in almost any kropki sudoku there is!

Rules: Normal sudoku rules. A white dot separate two cells containing consecutive digits (i.e. with a difference of 1). A black dot separate two cells with a ratio 1:2 (i.e. one digit is double the other). Not all dots are given.

Fun puzzle. I couldn't crack it without 1 guess but I'm sure I missed something. Thanks for sharing!

Excellent tutorial. I know all this stuff, but enjoyed it anyway.

Newcomers should benefit from giving this one a whirl (imho)! I cannot think of any Kropki insights that are not here (except, arguably, if the black dot above the 4 had been to the left instead).

Reply: Thanks, hope it can help some people join the sudoku variant world! I guess you can create more logic with using the whole grid, or negative constraints, but this would be more puzzle specific, and a bit hard for a tutorial.
