November City construction Month (2) - Spiral
Place all buildings in the grid. Buildings may be rotated. They may not touch each other, not even diagonally. All unused cells form a single, closed loop. The given grid is a spiral. Building segments are numbered from 1 to 32, starting from the entrance of the spiral (top left) and moving towards the center. The numbers outside the grid are the sum of the building segments in the corresponding row or column.Inspiration for this puzzle comes from the August LMI puzzle test.
Puzzle:
Solution code: The number of knicks in the loop; row by row, top to bottom. (Example: 40228244)

Such fun. Always love your puzzles because I can do them (not impossibly hard) and always so much variety!

Durch das Einarbeiten im anderen Rätsel ging das jetzt flott. Klasse!

@lupo: Ging mir ganz genauso - ich wollte schon meckern, daß die Lösung nicht eindeutig ist, hab mir aber vorher nochmal die Kommentare durchgelesen :-)

Strange combination for me in the beginning but really a good idea. Well done and fun to solve.

To be honest: In general I don't pay attention to examples, if the rules are clear enough. But for this special puzzle it was helpful to have a look on it.

I know it is quite some effort to create an example. In German we say: "Ein Bild sagt mehr als tausend Worte" So I think it is very useful, especially for new ideas and puzzle variants.

Is it useful to make example puzzles? After reading comments I doubt if I should continue with that? It should save me a lot of time to skip examples...

@pin7guin: Ging mir ähnlich. Allerdings hab ich die Rundwegbedingung erst bemerkt, als ich die letzten drei Felder nicht mehr eindeutig zuordnen konnte und mir daraufhin die Regel nochmal durchgelesen habe...

Das hat Spaß gemacht.

Wenn man im Auge behält, dass ja auch noch der Rundweg drumherumpassen muss, wird das Rätsel gleich viel einfacher... :-)

Schade, schade, schon ist der Rätselspaß wieder vorbei! ;-)) Schönes WE!
