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. Some types of puzzle have less than nine symbols.

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 type, Standard Sudoku, 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.
