Logic Masters Deutschland e.V.

Passing Sand Worms split the land in 4 pieces. The main one is a 10-regions irregular Squished Sudoku, the second piece is a single 3x3 region and the rest are single cells.

Rules

Squishdoku: Place digits from 1-9 in every cell, so that no digit repeats in a row, column, or 3x3 region (there are 11 regions total). The dashed lines indicate the boundaries of regions, and cells on the lines are simultaneously part of the regions on all sides of the line.

Kropki: Standard Kropki rules apply. All black and white dots are given.
