Link to original post : Sudoku Variants Series (061) - Before Nine (von 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. Before Nine Place the digits from 1 tot 9 in every row, column and 3x3-block. Clues outside the grid are the sum of the digits that are placed before the 9 in the corresponding row or column. This variant appears in the coming GP-round, from 30 January till 2 February so you can have some extra practise. (37 mal gelöst, sehr leicht, schön)
