Logic Masters Deutschland e.V.

Standard sudoku rules apply. Renban rules apply - the digits on each line make a set of consecutive digits, in any order.

Kropki rules apply – two cells connected by a white dot are consecutive, two cells connected by a black dot are at a 1:2 ratio.

All kropki dots start hidden. Each renban line has revealed all possible kropki dots strictly within the same regions. One additional kropki dot has been revealed for you.

Solve it here on f-puzzles, enjoy.
