The rules of Jigsaw Sudoku are, Each row must contain the numbers once, and only once. Each column must contain the numbers once, and only once.

The grid starts out with some positions populated and your job is to fill in the remainder. The numbers must meet certain criteria, specifically that the same digit cannot occur more than once in any column or more than once in any row.

Additionally, you'll notice the sudoku grid is divided into 9 squares, each 3x3, and a digit can also only occur within these squares.

These three constraints, that a digit not occur more than once in a row, column or square, make up the basic rules of sudoku. Suduko puzzles typically get more challenging depending on how many numbers are supplied in the initial puzzle.

When there are many numbers supplied, it is easier to figure out which numbers can be put into a specific place in the puzzle.

For example, if eight out of nine positions in a sudoku column already have a value, the nine position must contain the digit not already mentioned in the column.

This same strategy of finding missing digits easily extends to rows or squares. Where sudoku puzzles get challenging is when there are multiple open positions in a row or column In these cases you may need to look at more than one part of the puzzle to figure out how to solve the puzzle.

Consider a row that is missing digits 5 and 6. If that's all the information you have, you have little to do except guess.

However, you could look at the column that intersects one of the blank positions in the row. If that column already has a 5 in it, you know the value that goes in the blank position MUST be 6 because putting a 5 there would violate one of the sudoku rules.

This sort of mutual exclusion is a powerful way to filter out possible values in your solution, and with a little practice you can apply it with rows, columns and squares.

There are many more complex strategies for eliminating potential numbers, but most strategies rely on these simple means of exclusion and thinking one or two steps ahead in the search to see if the solution fits.

This slightly non-deterministic approach to problem solving is one of the characteristics of sudoku puzzles that makes solving them so addictive.
