Sudoku Variants Series (198) - XXV Sudoku

(Published on 12. September 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.

XXV Sudoku
Apply normal Sudoku XV rules: All horizontally and vertically neighbouring digits with the sum 10 are marked with X, all horizontally and vertically neighbouring digits with the sum 5 are marked with V. Additionally, all squares where the sum of the digits adds to 10 are marked with X in the center of the square.

Inspiration for this type comes from WSC 2011.

Solve online in Penpa+ (thx Nick Smirnov!)

Solution code: Row 6, followed by column 1.

You are right. There was a missing X. Unnoticed by me and my tester. Of course it wasn't meant to be there. I hope the difficulty level is still ok now.

I agree too...

azalozni: I agree, there seems to be a missing X. My solution that was accepted isn't really correct.
