Every Pentomino is used at most once.
Two neighboring Pentominos touch each other exactly at one side of one cell.
Pentominos may never touch each other diagonally.
The given Pentominos may be rotated and/or mirrored.
The digits in the cells indicate the number of sides of that cells that are used by Pentominos.
For an example see: Pentomino Loop
"49" = Number of fields outside the loop (and without fields enclosed by the loop).
Solution code: Row 5 and column 2: The letter of the pentomino or "-" for an empty field.

Ganz schönes Umdenken zu den normalen Rundwegrätseln. Für mich deutlich schwerer als die ersten 5 der Serie.

Brilliant observation (haven't proved it yet). But strange ideas you have I'd say ;-).

Interesting fact: this also has a unique solution as a slitherlink filled with pentominoes,where the clues are defined as above.
