Introduccion

Sudoku is an application to generate and play the popular Sudoku logic puzzle (also known as Number Place).

The rules of Sudoku are quite simple. In order to complete the puzzle, you must fill each square with a number between 1 and 9 such that every row, column and 3x3 box on the board contains the numbers 1 through 9. Stated another way, you must fill each square such that no number appears twice in the same row, column, or 3x3 box.

These two different ways of looking at the puzzle are two of the principle ways players think as they play. On the one hand, you ask yourself, “How can I fit all the numbers in this box?” On the other hand, you ask yourself, “What numbers can fit in this square without causing a conflict with other numbers in the same row, column, or 3x3 box?”

In spite of the simplicity of the game, Sudoku puzzles can vary widely in their difficulty. Sudoku allows you to select the difficulty of the puzzle you want to play. By default, it will begin with easy puzzles and gradually increase the difficulty of puzzles as you improve.
