Sudoku Variants Series (010) - Answer Eight

(Published on 4. February 2014, 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.

Answer Eight
Place the digits from 1 tot 9 in every row, column and 3x3-block. Black dots in the grid imply that applying one of the binary operations (addition, subtraction, multiplication or division) on the two neighboring digits result in the number 8. If there is no black dot between adjacent cells, 8 cannot be produced by the two digits going through any binary operations.

Solution code: Row 2, followed by column 5.

Really nicely made. So much better than the average software-generated puzzle. Thanks Richard!
