@CHalb: it really helps to know how this puzzle type works. And to have a lot of experience and a little bit of luck! :-)

I came straight through this with a bunch of thouroughly noted candidates. Nevertheless this is one of Richards' puzzles, where I have not the glimpse of an idea how one might construct it by hand.

Nein, die 9 und die 1 haben bei diesem Rätseltyp jeweils nur einen Nachbarn.

Kurze Frage: Folgt nach der 9 wieder die 1?
Danke und Gruß
