Pentomino-U-Bahn

(Published on 19. January 2012, 17:54 by ibag)

Draw a map of an underground with lines from center to center of orthogonally neighbored fields. At the center of a field the lines may run straightforward, turn or branch. There are no dead ends. The underground cannot leave the grid. The numbers at the borders give the corresponding numbers in that row or column. The pieces may be rotated.

The total underground plan encloses an orthogonally connected region. This region is devided by the lines exactly into the 12 pentominos. The pentominos may be rotated and/or mirrored.

Example, using the pentominos, L, P and T:

Solution code: The hint numbers of row 5 from left to right, followed by the letters of the pentominos which are passed by the border between column 7 and 8 from top to bottom (every letter only once).

Sehr schönes Rätsel, aber Aufmschlauchsteherei gehört durchaus zum beruflichen Risiko

Es ging langsam, aber stetig - und immer logisch lösbar - voran. Danke, Gabi!
(Auch wenn Pentominorätsel nie meine Lieblingsrätsel werden werden.)
