Sudoku Variants Series (170) - X? Sums Sudoku

(Published on 28. February 2017, 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.

X? Sums Sudoku
Place the digits from 1 tot 9 in every row, column and 3x3-block. Numbers outside the grid indicate the sum of the first X digits in the corresponding direction. X is the first digit in the corresponding direction. The value of ? is always the same. All possible ?’s have been placed as clue outside the grid.

Solve online in F-Puzzles or CtC-app (thx Nick Smirnov!)

Solution code: Row 3, followed by column 8.

hm, komisch, gelöst, alle Fragezeichenwerte gleich und trotzdem falsche Lösung. Da muß ich wohl nochmal neu Hirn einbringen...

Spannend, wenn man erstmal gründlich denken muss, bevor man mit dem Lösen starten kann. Danke, Richard!
