-Story line-

After a whole week of looking into my Kropki Machine and tweaking it, it decided to do things worse than previously. God knows how quirky these puzzles will be getting. This time it messed with the grid size. I managed to salvage a puzzle from all of this fuss.

-End of Story line-

Apply classic Sudoku rules : Each row and column and must contain the digits 1-9 once. Digits may not repeat within a bold-outlined region.

• Kropki rules are as follows : when two digits are consecutive, a white dot is placed. When a digit is half the other (e.g. 3/6, 4/8 etc.), a black dot is placed. All possible dots are given. A 1/2 pair can be indicated by either a black or white dot.

In this puzzle however, there is a digit N for which all dots were removed (i.e. if N=6, then 5/6 and 6/7 pairs don't have a white dot, and 3/6 pairs don't have a black dot). All other digits follow the classic Kropki rules.

You can use Penpa-edit for solving it on your browser.

And please let me know if anything is wrong with the puzzle. I don't recall a time when I didn't make any mistakes and I'm having nightmares with these kropki dots.
