Logic Masters Deutschland e.V.

Chaos Construction: Divide the grid into five regions. A region is a group of five orthogonally-connected cells. Each region contains exactly one unbroken renban line, but may contain any number of partial renban lines.

Renban Lines: Each pink line contains a set of non-repeating consecutive digits in any order.

Kropki dots: Cells connected by a white dot are in the same region, and contain consecutive values. Cells connected by a black dot are in different regions, and contain values with a 2:1 ratio.
