Puh, hier habe ich echt laaange gebraucht, bis ich den Einstieg gefunden hatte. Aber nach der ersten Ziffer ging es gut und immer besser vorwärts. :-)

In normal non-consecutive puzzles (1~9) the question if the first and last digits of the sequence may be in adjacent cells is never asked. I don't see why it should be questioned if the sequence contains one digit extra. Asked is a sequence with a start (0) and a last digit (9). Of course they may be next to each other.
The previous time a puzzle of this type and size appeared, 0 and 9 were also allowed to be adjacent. See: http://www.logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=0000WM

Darf die 0 an die 9 grenzen?
