Sudoku Variants Series (016) - Extra Regions Sudoku

(Published on 18. March 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.

Extra Regions Sudoku
Place the digits from 1 tot 9 in every row, column, 3x3-block and each colored extra region.
In this puzzle a very interesting variation to the Law of Leftovers can be applied!

Solve online in F-Puzzles (thanks Nick Smirnov!)

Solution code: Row 2, followed by column 8.

I found this to be a consistently hard, but very satisfying solve. Thanks for the puzzle. Now I'll see if I can understand all the SET theory in the comments.

As someone who solved quite a decent amount of jigsaw puzzles already but still never understood how the law of leftover really works, this was still quite a comfortable solve, the puzzle made it easy to set up contradictions and the regions are easy on the eyes.

Lieber Richard, vielen Dank! Wieder einmal ein sehr schönes Rätsel. Aber ich wüsste sehr gerne, was es mit der Variante des "Law of Leftovers" auf sich hat (vor allem da ich mich mit irregulären Gebieten immer sehr schwer tue.)

Lieber Richard, vielen Dank für dieses und Deine anderen Rätsel. Ich freue mich jedes Mal darauf!

Hat lange gedauert, bis der Groschen bei mir gefallen ist. Aber es lohnt sich, es ist eine tolle Konstruktion.
