Play in Sudokupad
Choose a set of six digits from 1-9 and fill the irregular sudoku so each of the selected digits appears once in every row, column, and marked region.
Kropki dots: Black dots indicate cells with a 2:1 ratio. White dots indicate cells with consecutive digits.
Negative constraint: All dots within a region are given.
Note: If it occurs in the grid, within a region, a pair of 1-2 will be marked with either a black or white dot.
Solution code: Row 6

simple but clever; a pretty puzzle with a fun rule set -- I'd love to see a 9x9 or even a chaos construction with a similar idea

Proof that a puzzle doesn’t have to be difficult to be elegant. Well set.
