With various games that people play online and most are for free, it could be a bit confusing whether which one provides entertainment and fun, or which game offers educational benefits too. Among many educational games out there, Sudoku is quite popular. Why? We’ll get to know the reasons below. 

What is Sudoku?

Sudoku is originally called Number Place. This game is a logic-based and combinational number-placement puzzle. The objective of the game is to fill the 9×9 squares with digits so that each row, or each column, and each of the nine 3×3 sub-squares which comprise the grid contain all the digits from 1 to 9. 

Sudoku Games: A Brief History

Number puzzles appeared in newspapers in the late 19th century when French puzzle setters started experimenting with eliminating numbers from the magic squares. On November 19, 1892, one daily newspaper in Paris published a partially completed 9×9 magic square having 3×3 sub-squares.

Nevertheless, it wasn’t named as Sudoku since it contained double-digit numbers and it required arithmetic instead of logic to solve. However, it shared some key characteristics of Sudoku like each column, row, and sun-square added up to the same number. 

The said puzzle was then refined on July 6, 1895, which was almost considered as the modern Sudoku. The modern Sudoku was designed by Howard Garns and it was first published by Dell Magazines named as Number Place. 

In April 1984 in Japan, the puzzle was then introduced by Nikoli in the paper titled Monthly Nikolist which was named as Sūji wa dokushin ni kagiru. This can be translated as “the digits are limited only to one occurrence” or “the digits must be single”. And later on, it was named as SUDOKU.

Tips on How to Play Sudoku

Consider the following tips on how to play sudoku:

  • First, look for the easy play. As you begin playing a Sudoku puzzle, you should look for where you have the easiest opportunities to add numbers. In most cases, this is where there is a row or a crowded square which is almost full of numbers. You can use the process of elimination to figure out where you can place a number.
  • Look for what numbers are missing. Since sudoku is a game of placing numbers on where they don’t already exist, it is a logical process of elimination. Once a number already exists in a square or a row, then the number could not be placed again. Keep thinking or looking for opportunities to add numbers on where they haven’t been placed already.
  • Avoid guessing. This game doesn’t need guesswork. Once you are not sure if the number belongs in a specific spot, you shouldn’t guess.
  • Just keep on moving. If you feel stuck, you must not concentrate too much on one part of the grid. Rather, let your eyes and mind wander into a different place on the grid where you have not put any numbers yet and see new possibilities good for you.
  • Always re-evaluate. As you place a new number on the grid, always re-evaluate. Every time you put a number, it offers you the chance to possibly put more numbers in nearby squares and rows. 

Sudoku Rules

Every game has its rules. With regards to Sudoku, here are some of the rules to take note:

  1. Use Numbers 1 to 9. A sudoku game is played on a grid with 9×9 spaces. And within these columns and rows are nine squares. Each column, row, and square must be filled out with the numbers 1 to 9, without having to repeat any numbers with the column, square, or row.
  2. Don’t repeat any numbers. By seeing what numbers are missing from the column, row, or square, use the process of elimination and deductive reasoning in order to decide what numbers to put in each blank space.
  3. Don’t guess. Don’t try to force anything. Sudoku game rewards insights, patience and recognition patterns and not guessing or blind luck.
