Sudoku Variants Series (253) - Makodoku

(Published on 26. March 2019, 00:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every second Tuesday. I will see how long it takes before I am running out of ideas.

Makodoku
Apply classic sudoku rules. All pairs of adjacent digits with a product less than 10 are marked with a cross sign. All pairs of adjacent digits with a sum less than 10 are marked with a plus sign. If both signs are possible, a cross sign is drawn. If there is no sign between two cells, the sum and product are both minimal 10.

Inspiriation for this type comes from WSC 2018.

Solve online in Penpa+ (thanks Nick Smirnov!)

Solution code: Row 5, followed by column 5.
