How to Play Sudoku?
Sudoku requires no calculation or arithmetic skills. It is essentially a game of placing numbers in squares, using very simple rules of logic and deduction. It can be played by children and adults and the rules are simple to learn.
The objective of the game is to fill all the blank squares in a game with the correct numbers. There are three very simple constraints to follow. In a 9 by 9 square Sudoku game:
Every Sudoku games begins with a number of squares already filled in, and the difficulty of each game is largely a function of how many squares are filled in. The more squares that are known, the easier it is to figure out which numbers go in the open squares. As you fill in squares correctly, options for the remaining squares are narrowed and it becomes easier to fill them in.
Ricardo adds, "Of course it's not as sophisticated as the ones designed for the current O.S. of today. It does not generate new puzzles, nor solves them, not even check when a puzzle is solved by the user. But...
It gives some hints as you move the cursor around and there are 20 pages of sudoku puzzles that can be played, edited and saved."
"My approach was to design something near a sudoku paper book. So you can browse the pages at will and work on any puzzle for a while then move to another and play with it and when you're bored you can save the entire book with all your previous inputs and continue playing on a later time."

To enter a number, just type it. It will be accepted if valid.
To clear a cell input use the 0 (zero) key.
With the N and P keys it is possible to choose one of the 20 pages to play.
Use the C key to clear all inputs on a page and start over.
The E key toggles between edit and play modes.
The Q key quits the game.
After quiting you can "save mysudoku" to continue playing it later.
