Sudoku Variants Series (060) - Quad Sums

(Published on 20. January 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.

Quad Sums
Place the digits from 1 tot 9 in every row, column and 3x3-block. A circle at a corner implies that one digit is the sum of the remaining three digits at that corner.

Solve online in Penpa+ (thx Nick Smirnov!)

Solution code: Column 4, followed by column 6.

Nee, da's lekker. Een lagere waardering toekennen omdat je de instructies niet goed leest! :-)

Ganz tolles Rätsel, die beiden Quadrate mit vier Punkten sind 'ne Wucht!

Corrected the solution code description in the German version. The code contains columns 4 and 6 instead of rows 4 and 6. The English version was already correct.
