Logic Masters Deutschland e.V.

Permaculture: Divide the grid into 2 subgrids of orthogonally connected cells. Solve one subgrid according to Pentominous rules, and the other according to Narrowfence rules.

Pentominous: Divide the subgrid into pentominoes (5-cell regions). Pentominoes of the same shape cannot be orthogonally adjacent, counting rotations/reflections as the same. Letters indicate the shape of the pentomino they belong to. Pentominoes may contain any number of letter clues.

Narrowfence: Divide the subgrid into regions, each containing exactly one letter. Regions cannot be rectangular (including squares). Regions with the same letter cannot be the same shape, counting rotations/reflections as the same. No 2x2 area of the subgrid can consist of cells which all belong to regions with the same letter.
