Logic Masters Deutschland e.V.

Permaculture: Divide the grid along the grid lines into two orthogonally connected parts. In each part, solve one of the following two puzzles. The two puzzles are completely independent of each other and do not interact at all.

A 38: Draw a closed loop in the grid that crosses each field without clue number(s) exactly once and connects the centers of the fields orthogonally. The field with the black dot is the starting point of the loop. Passes must be acquired along the loop, which are required to cross the gray fields, and these are obtained on pass fields, which must be identified.

The clue numbers indicate the number of times, counted from the starting point, that one of up to eight neighboring fields must be crossed for it to be considered a pass field. All possible numbers are indicated, and no gray field may be considered a pass field. The loop must then alternate between pass fields and gray fields - even beyond the starting point and starting from there with a pass field.

Narrow Cave: Blacken some cells so that all white cells (the cave) are orthogonally connected and all black cells are orthogonally connected to the boundary. Cells with clue numbers always remain white. The clue numbers indicate how many cells can be seen in the orthogonal directions from the cell. The cell itself is also counted. The cave must not contain any 2x2 areas.

Some clue numbers are Easter eggs and have yet to be found.
