  • People that are new to Sudoku puzzles are going to have great difficulty in solving one. On one side there are so many numbers, and it seems so mathematical. Moreover, on the other side, if you do not have any appropriate solution techniques, it is going to take a lot of guessing and checking as well. In reality, these puzzles are well structured and pretty predictable like general mathematics. There are a few aspects of Sudoku puzzles. Before learning more about them, let’s take a look at some of the basics of Sudoku including the rules, in the game and terminology. What is Sudoku? For anyone who is still not aware of it, should know that Sudoku is s a logic-based and number placement puzzle. It is in the format of a box divided into 9*9 rows and columns including 3*3 sub-grid that results in total 81 cells which are also called Latin square. The aim here is to fill a grid with numbers in a way that each of the columns, each row, and all the grids must contain numbers with digits from 1 to 9. Every Sudoku puzzle starts with some of the cells already filled in. The players use these hints as a starting point so that they are able to find a unique solution. The main point to note here is that you cannot repeat the numbers from 1 to 9 in any of the rows or columns. Although you can repeat these along the diagonals. You have to cross all the constraints of the box.
