Sudoku Variants Series (099) - Twin Killer

(Published on 20. October 2015, 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.

Twin Killer
Apply classic sudoku rules. The small numbers in the dotted outlined areas are the sum of the digits in that area. Within a dotted outlined area all digits must be different. Both grids have the same solution.

Solve online in Penpa+ (thx bbutrosghali!)

Solution code: Row 3, followed by row 9.

@ildiko: haha, no my last name is not SPORT, although it comes close: STOLK

Das war jedenfalls ein besonders schönes Exemplar!

Juhu! Endlich mal wieder ein Killer (meine Lieblingssudokus) und gleich ein Twin - Danke, Richard. Der Abend ist gerettet - es kommt eh nichts Gescheites im Fernsehen.

Was ich mal fragen wollte: Heißt du mit Nachnamen eigentlich "Sport"? Gab es das nicht schon früher im Fernsehen: Richard Sport - quadratisch, praktisch, gut! ;-)

@Senior: thank you for your kind words and your impressive investigation on the statistics! Some interesting conclusions can be made. I also hope that over 10.000 submissions will be made for the series. As far as I can see I am halfway through with all the variants...

Wieder einmal ein Genuss!

Danke, Richard, für diese einzigartige Serie von nunmehr 100 verschiedenen Sudokuarten!

Von Dezember 2013 bis heute gaben im Rahmen deiner „Sudoku Variants Series“ insgesamt 183 Rätselfreunde über 7500 Lösungen ab. Man kann also mit Fug und Recht davon ausgehen, dass du dem Sudoku einige neue Freunde gewonnen hast. Auf mich trifft diese Feststellung jedenfalls zu.
Ich verbinde meinen Dank mit einer kleinen statistischen Auswertung, die man im Forum einsehen kann.
