KSudoku is a logic-based symbol placement puzzle.

The player has to fill a grid with symbols so that each column, row and block on the game board contains only one instance of each symbol. In KSudoku the symbols are usually the numbers 1 to 9, but may be the letters A to P or A to Y in larger puzzles. Puzzles start with the board partially filled and it is your job to fill in the rest.

When you start a game, you can choose from several Sudoku types and sizes. You can then have KSudoku generate a puzzle for you to solve or you can start with an empty board and enter in a puzzle from another source, such as a newspaper, then get KSudoku to check it and maybe solve it.

There are many variations of Sudoku in existence and KSudoku provides a good selection of them. The most common variant has a 9x9 square grid and uses Arabic numerals 1 to 9 as symbols. The grid has 9 rows and 9 columns and is divided into 9 blocks of 3x3 squares. The problem is – each symbol can only be used once per row, column or block.

Note

It takes time and concentration to complete a game. However, solving Sudoku puzzles helps to increase overall brain activity and therefore is highly recommended.
