Sudoku is easy to learn logic-based number placement puzzle and very popular all around the world. It is indeed a game for all ages: from kids in preschool to grown-ups. It is possible to form and solve a Sudoku puzzle with letters or even some symbols. A classic Sudoku puzzle is an 81-cell square grid made up of 3 x 3 sub-grids or 9 smaller blocks, also known as regions and boxes. Some cells already include numbers (called as givens). The game aims to fill all the blank cells with one digit from 1 to 9 in such a way without ever repeating a single one in the same row or the same column, or in the same block to solve it correctly.
