Sudoku Rules

I would say there is only one rule to play this puzzle. Each row, each column, and each 3x3 sub-grid should contain the digits 1 to 9. No row, column or grid should have any number more than once. This rule is mentioned considering the regular 9x9 grid puzzle. For more such tips you can refer sudoku todays in page http://sudokutoday.com/

Strategy

There are basic three things that you need to keep in mind

• Scanning

This is a vital step that you need to perform. Keep scanning the puzzle for the missing number while solving the puzzle. When you start solving the puzzle, you would quickly glance through it and fill up the missing number after analyzing the number in the adjacent rows and columns. Once the puzzle starts to get a bit difficult to solve, then you stop scanning. You need to make sure you keep scanning the puzzle after every one or two new entries.

• Marking

When solving medium or hard level puzzle, there would be a point, where you would get stuck and no further scanning would be possible. Here, you need to analyze a bit and start marking the approx option. You can either use dots or subscript numbers to mark the missing numbers. When the print of the puzzle is large, it is advisable to use subscripts. It is difficult to use them in regular size print, hence one can use dots. A dot in the left hand side corner means 1 and a dot in the right hand side corner means 9.

• Analyzing

• In the elimination strategy, the candidate numbers are eliminated, which finally leads to only one choice. After every number is filled in the puzzle a scan must be done of the entire puzzle.

• The what-if strategy is based on guess. The 3x3 sub-grid that contains minimum numbers is selected and the numbers are filled based on the analysis of other sub-grids. During the process of solving the other girds, columns, and rows, if the number in this sub-grid is found to be double, then it needs to erased and logical number should be placed.
