Sudoku Variants Series (147) - Snake Sudoku

(Published on 20. September 2016, 00:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every Tuesday. I will see how long it takes before I am running out of ideas.

Snake Sudoku
Place the digits from 1 to 9 in every row, column and 3x3-block. There is a snake hidden in the grid with head and tail on the grey cells. The snake doesn't touch itself, not even diagonally. It has the form 123456789123..., starts with 1 and ends with 9.

Inspiration for this puzzle comes from Statistica.

Solve online in F-Puzzles (thx bbutrosghali!)

Solution code: Row 4, followed by column 6.

This was by far the most brutal puzzle in this series so far. It took me several attempts over the last months and many trial and error. Would like to see whether there is a more elegant solution.

Lieber Richard, vielen Dank für deine phantastische Serie. Dieses Rätsel hat mich allerdings verzweifeln lassen. Heute Habe ich es endlich lösen können . Ich freue mich schon auf die Fortsetzung, wann auch immer.

Manche Rätsel lassen sich erst lösen, nachdem sie eine zeitlang weggelegt hatte... :-)

Wenn zwei diagonal benachbarte Felder beide Teil der Schlange sind, sind sie immer zwei Glieder voneinander entfernt. Gemeint ist, dass es kein Gebiet innerhalb der Schlange geben darf und dass es kein Quadrat mit vier Schlangenfeldern geben darf.
Ist nicht leicht, das Ding, auch ich hab ziemlich lange daran rumgebastelt ;-).

Hm, nun basteln wir schon einige Zeit, aber irgendwie... zumal sich bei einer nur h/v-Schlange diese auf jeden Fall diagonal berühren muss ... ???

Schöne Idee, hat mir gut gefallen :)

@Hasenvogel: nur h/v.

Darf die Schlange auch diagonal verlaufen oder nur horizontal/vertikal?
