Logic Masters Deutschland e.V.

Rules:
Permaculture: Divide the grid into two orthogonally connected areas such that every cell is part of one area. One of the areas is a Meidjuluk puzzle, the other area is a Snake Egg puzzle.
Meidjuluk: Divide the area into regions of orthogonally connected cells. There must exist one region of each size from 1 to N. A region may only contain numbers which are factors of the number of cells the region contains. Regions may not contain multiple instances of the same number.
Snake Egg: Shade some cells to form a non-intersecting path which does not branch and not touch itself orthogonally. Exactly one orthogonally connected area of unshaded cells must exist of each size from 1 to N. Cells with numbers cannot be shaded (except the start and end "digits"), and represent the size of the area they’re in, if given. Two of the given digits, which are identical, mark the start and end of the snake's path, but must be found by the solver.
Interaction: For both rulesets, N is the same, but must be deduced by the solver.
