Sudoku (Japanese:数独, Sudoku) is a hobby that became popular in Japan in 1986. The goal is to fill a 9 × 9 grid cells (81 boxes) sub divided into 3 × 3 with the numbers 1 to 9 on some numbers already provided in some of the cells. What matters, however, is that they are nine distinct elements. You should not repeat any figure in the same row, column or sub. A sudoku is well posed if the solution is unique. The resolution of the problem requires some patience and logic skills.La Familia y El Hogar Boletín es presentada por.
