Starting with this, and in successive deliveries, we will address how to resolve sudoku quickly and efficiently.

Solve a Sudoku

Let's start by reviewing the basic rules of the game:

In this first lesson we will expose some useful tips when solving sudokus.

  1. Use a pencil . It is much more comfortable to make a sudoku in pencil than on a computer screen. In addition, the pencil allows you to erase it in a simple way.
  2. Practice gradually. Usually many newspapers and magazines do not catalogue sudokus because of difficulties so, for a neophyte, it can be really complicated to finish a complex sudoku. At we catalogue sudokus so that you can practice with sudokus according to your level. The higher the level the more difficult it will be (usually) to put the numbers and, in the case of the very difficult ones, sometimes you will have to try plays.
  3. To test plays there is nothing better than typing the candidate numbers in the upper left corner of the cell. If you write small or in a margin, as you discard numbers, strike them out.
  4. Take it easy , sudoku is a relaxed game. Some sudokus can be resolved in a matter of minutes but others may take hours or maybe days.
  5. Well-designed sudokus have a unique solution, use this feature to your advantage.
  6. Never feel until you have finished carefully examining all the possible moves.
  7. Follow an order in the placement of the numbers, a good tactic is to start with the numbers that appear more frequently ending in the less frequent; in case of ties decide the order and follow the whole game.
  8. Check that every step you take is valid, a failure at first can be disastrous.
  9. If you don't find a possible solution, ask for help, or try sudoku at another time. Many times the solution appears when you least expect it, and not always when you are in front of the sudoku. ;).
