Sudoku Yeah!

This addictive game drives thousands of people crazy. It is a set of cells that make more than one person pull their hair after trying to solve it and stay halfway. It can be understood that Sudoku is based on the search for a perfect numerical combination. Teachers from around the world recommend it as a method to develop logical skills. The objective of the game is to fill a grid of 9 × 9 cells (81 squares) divided into smaller grids of 3 × 3 with the numbers from 1 to 9, starting from some numbers already arranged in some of the cells. No number should be repeated in the same row, column or sub grid. There are different levels of difficulty and the resolution of the problem requires patience and a little mastery of logic. Explaining this in a simple way, each number can appear only once in each row, column and region. TIP: Use pencil and eraser.
