Sudoku Variants Series (000) - Classic Sudoku

(Published on 3. December 2013, 12:00 by Richard)

For a long time I am surprised about the vast number of Sudoku variants that is invented over the years. I have written a lot of different variants too, for championships, the puzzle portal and online tests, but after all those years there are still a lot of variants of which I didn’t write a puzzle myself.
So today is the start of a new project. I will publish a different Sudoku variant every week at Tuesday noon and I will see how long it takes before I am running out of ideas. For this purpose a variant has only one single constraint; combining two variants is not a new variant for this series. Also, I do not distinguish between a variant where ‘all possible dots are given’ and the same variant where ‘not all possible dots are given’ in case of a variant with a constraint on neighbouring cells. Mostly I will choose the variant where ‘all possible dots are given’.

Classic Sudoku
For the preparation of my list of variants, I looked a lot in the portal. I noticed that among the 2.100 puzzles in the portal there is not even one single Classic Sudoku. So the Variants Series has a funny start; its prologue is a Classic Sudoku: place the digits from 1 to 9 in every row, column and 3x3-block.

Solution code: Row 5, followed by column 1.

Das erste von meiner Mutter gelöste Portalrätsel. Da steht einem eigenen Account nichts mehr im Weg :-)

A simple and nice classic Version - good for training of some solving paths.

Mögen dir die Ideen nicht ausgehen, damit wir uns die nächsten 19 Jahre auf den Dienstag freuen können. Ich denke, ich bin nicht die einzige, die eine Kombination von zwei Varianten durchaus als als eigene Variante begrüßen würde. Je mehr, desto besser.

@berni: it will be 010. :-)

Wenn man sich das (000) anschaut, dann kriegt man so eine Idee, in welcher Größenordnung Richard die Anzahl der Varianten sieht... Spannend wird es dann allerdings beim elften Sudoku: Lautet die Zahl dann 010 oder 00A?
