The Layout of Suduko

The regular Suduko puzzle board consists of a 9 x 9 grid. This grid is further divided into 3 x 3 sub-grids bordered with bold lines. They are called boxes or blocks or, at times, regions. A total of 81 squares make up the game board. Some of these squares have numbers in them already, while the remaining squares are blank. The numbers generally used are from 1 to 9.

Rules of the Game

Start the game by filling the squares with numbers. Use logic to decide the appropriate number for the square. You should fill up the squares in such a way that:

• Every row must exhibit ALL the digits from 1 to 9.
• Every column must exhibit ALL the digits from 1 to 9.
• Every 3 x 3 block or box must exhibit ALL the digits from 1 to 9.

Point to remember: All nine digits can appear only ONCE in each row, column, and block. Challenging.

Maddeningly so.

The ultimate objective of the puzzle is to have the numbers 1 to 9 properly allocated across each row, column, and block. And you have to complete the game fast. You don't have all day to work on the puzzle..

Simple Rules, Complex Game

The rules of Suduko are quite simple. That's its main attraction. Games with lengthy and complicated rules turn most people off. However, simple rules don't indicate a simple game—another powerful draw. Initially, you may feel it's easy, but as you proceed, you'll realize how complex Suduko is.

Your mind will become consumed with a world of digits. You'll lose track of time, captivated with this amazing puzzle of numbers. Once you start playing Suduko, you will fall in love with it! You will become a Suduko-addict.

And addiction is just the beginning. There are many other varieties of Suduko available. Some of them use symbols or letters instead of numbers, while others use more than nine digits.
