Sudoku is a number puzzle that requires you to use logical thinking to fill in blank squares.

Sudoku is one of the most popular puzzles on the planet. One of the main reasons for this is that you can learn how to play Sudoku in no time at all.
Here are four top tips and strategies that will help get any beginner started when they’re playing Sudoku.
Sudoku is usually played on a 9x9 grid. Each space needs to be filled with the numbers 1-9. The challenge lies in not repeating any numbers in a row, column or square.
Easier Sudoku puzzles have more numbers added to the grid before you start, making it simpler to solve the challenge.
Numbers aside, Sudoku really isn’t a math game. Rather, it’s based on logic, so guessing won’t get you very far. In fact, each Sudoku puzzle has only a single solution.
Patience is key to Sudoku! If you get stuck or need to take a break, our puzzles will automatically save so you can return right where you left off.

The origin of Sudoku comes from puzzles printed in French newspapers during the 19th century. These puzzles asked gamers to remove numbers from squares, creating the foundations of the game that is played today.
On 19 November 1892, a Paris newspaper, Le Siècle, included a puzzle featuring a 9x9 grid containing 3x3 squares. However, while it shared important characteristics with Sudoku, it differed from Sudoku in a few key ways:
These puzzles remained popular in France until the end of the first World War.
Fast-forward to 1979 and these French puzzles were adapted by a retired American architect, Howard Garns, and published in Dell Magazines as Number Place.
This was then adopted by Japanese company Nikoli in 1984 and published under the name Sūji wa dokushin ni kagiru, before being shortened to Sudoku.
Sudoku is an abbreviation of the Japanese term 数字は独身に限る(Sūji wa dokushin ni kagiru). This means "numbers are single". Single comes from dokushin, which means an "unmarried person" in Japanese.
The abbreviation Sudoku was created by Maki Kaji, the president of Japanese puzzle company Nikoli. The name was trademarked by Nikoli and remains registered to this day.
Whether you play Sudoku online or in a written publication, the game has a simple aim: to fill all the cells in the 9x9 grid and 3x3 squares with numbers from 1 to 9, with a single occurrence included in the rows, columns, and squares.
The puzzle starts with some squares including a number in them and others being blank. The goal of the player is to use logic to put the correct digits into the blank squares.
If a Sudoku puzzle has been published correctly then it will have one answer.
However, that’s not to say that Sudoku can’t have two answers, or even multiple solutions. This may happen if you’re playing Sudoku online and the puzzle has been left intentionally incomplete (no pre-filled numbers).
Indeed, in the most acute example of an incomplete puzzle, there could be 6,670,903,752,021,072,936,960 answers to the Sudoku game you’re playing.
