1. Playing Sudoku

Q1.1 What is Sudoku?

Sudoku is a Japanese number game. It has been revitalized recently and has become extremely popular in Japan and the rest of the world.

Q1.2 Why should I play Sudoku?

There are many advantages to playing Sudoku.

  • First of all, it is a lot of fun and challenge. The satisfaction of solving a game can be very rewarding.
  • Like many other puzzles and games, Sudoku makes the players think and correlate information, which can help increase concentration and brain power. Playing around with numbers can also help kids become more comfortable with numbers and maths.
  • Sudoku does not require expensive specialized equipment to play; just a pencil/paper and a home PC for everyday use are all you need.

Of course, you may have your own reason for playing Sudoku. In any case, have fun while at it!!

Q1.3 What rules must I follow while playing Sudoku?

Please see the rules page for more information on how to play the games.

Q1.4 Why does my Sudoku have an irregular shape? How do I play this one?

Sudoku has many variations, and the game you are trying may be one of the variations. Please see the rules page, which describes rules for playing regular Sudoku as well as ones for playing the variations.

Q1.5 I am finding it difficult/impossible to get the solution. Should I just guess?

Guessing is usually not a good idea. Each Sudoku puzzle has a unique solution, which can be arrived at without any guesswork whatsoever. The Tips & Strategies page has some pointers on how to go about solving a Sudoku.

If you find a particular Sudoku too difficult, check the puzzle level. If you are just starting with Sudoku, start at the Easy level. With practice, you will get better and you can go onto more difficult and challenging levels.

There is also an option to get a hint to a cell when you find yourself stuck and unable to proceed. Use the "Track Errors" checkbox on the puzzle pages. This will dynamically mark cells in red if you make a mistake, so it that it is easier to backtrack and correct errors.

Q1.6 What is the best strategy to solve a Sudoku puzzle?

There are some strategies which can help in solving all Sudoku puzzles. However, there is no one hard and fast rule or formula which will guarantee a solution.

Q1.7 How do I know if my solution is correct?

Clicking on the "Check Solution" button will tell you whether your solution is correct or not.

This method works even if you have not filled in all the blank cells. In fact, it is a good idea to check your numbers every now and then. If this is not done, you can end up spending a lot of time solving the puzzle, only to find at the very end that you have gone wrong somewhere. It may be difficult to backtrack, since the errors accumulate in Sudoku.
