Logic Masters Deutschland e.V.

Rules:

Fillomino: Divide the grid into orthogonally connected regions and fill each cell with a number (not necessarily single-digit) showing the number of cells in the region to which it belongs. Two regions of the same size may not share an edge.

Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.

Every Fillomino region is either entirely shaded or entirely unshaded.

A number in a cell counts the total number of shaded cells in the direction of the arrow (not counting the cell itself).
