Logic Masters Deutschland e.V.

Rules:

• Normal sudoku rules apply.
• (Kropki dots) digits separated by a black dot must be in a ratio of 2:1. Not all dots are necessarily given.
• (Clones) Each coloured region in the grid has an identical copy in the other part of the puzzle, which contains the same digits, and is not rotated nor reflected in any way.

To clarify: this puzzle has two parts, and you need both parts to solve it.
