Doppelstern-U-Bahn
(Published on 7. July 2012, 16:39 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 into 8 orthogonally connected subregions.
At the intersection points of the grid stars must be drawn, exactly two on each horizontal and each vertical interior line, two into each of the 8 subdomains and two outside the underground plan. The stars must not touch each other, not even diagonally.
Example with 3 regions and only one star:
Solution code: For every row the number of intersection points between the stars, followed by the number of lines going to the right for the first 9 columns.

Der Berliner U-Bahn-Bau hat jetzt fast so lange gebraucht wie der Flughafen ;-))

Tolles Rätsel. Danke! Und ich habe mich erstaunlicherweise beim Code NICHT verzählt :-)

U-Bahnen alleine mag ich eigentlich nicht so, aber diese U-Bahn-Kombirätsel sind absolut toll! Danke!
