Classic Sudoku - very easy, vol. 9 Stroie Marius

" Sudoku (??, s?doku, digit-single, originally called Number Place) is a logic-based, combinatorial number-placement puzzle. In classic sudoku, the objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution. " ( source: Wikipedia )
