Logic Masters Deutschland e.V.

Rules:

Irregular Squishdoku: Place the digits 1 through 9 once each in every 9-cell region, without repeats in any row or column. Cells on region borders (dashed lines) are shared between multiple regions.

Dutch Flat Mates: Every 5 in the grid must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn’t need both.

Kropki Dots: White dots separate cells with consecutive digits. Black dots separate cells with digits in a 1:2 ratio. Not all dots are given.
