Sudoku Variants Series (009) - Next to nine Sudoku

(Published on 28. January 2014, 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.

Next tot nine Sudoku
Apply classic sudoku rules. Digits outside the grid are the direct neighbours of the 9 in the respective row or column.
Clues are written in increasing order.

Solve online in F-Puzzles (thanks Narayana!)

Als ein Sudokuspieler mit noch relativ wenig Erfahrung und bis heute nur erfolglosen Versuchen in Skyline-Rätseln sowie Skyline-Sudokus war dieses Rätsel zwar nach meinem Empfinden nach ziemlich schwer, hat sich aber sauber auf den ersten Versuch lösen lassen. Dieses Rätsel ist ein super Einstieg für diejenigen Rätsler, die sich vor Gitternetzrätseln (Schiffe versenken, japanische Bildrätsel, etc.) scheuen, aber solide Sudokukenntnisse haben, dieses Rätsel führt einen Optimal an die Basics des zweidimensionalen Denkens ran.
