Sudoku is easy to learn and understand. The main aim of Sudoku is to enter a number from one to nine into each cell on puzzle grid. The most frequent layout of a Sudoku puzzle is a 9 x 9 grid that is made of subgrids that are 3 x 3. Each of these subgrids is known as a “regionâ€. Depending on how easy or hard the puzzle is there will be various starting numbers in the cells. These are known as the “givensâ€. Every row, column, and region of the Sudoku puzzle can contain only one instance of each number. You complete the puzzle when all of the cells have been filled in with corresponding numbers.
To complete the Sudoku puzzle requires a lot of patience as well as the ability to think logically. The basic layout of the Sudoku grid is much like a chess game or crossword puzzles. Sudoku is not just a mathematical or arithmetic type of puzzle. It works just as well if the numbers are substituted with letters or other symbols. However, numbers work best.
The bottom line is that Sudoku is a fascinating new puzzle game that has taken the world by surprise and storm. You can now find Sudoku in many national newspapers. The great thing about this puzzle is that the basic principle of solving it is really quite simple. All you need to do is fill in the grid in such a way that each row, column, and region contains the numbers one to nine.
