Sudoku - The simple yet intelligent number puzzle

Sudoku, the popular and addictive number puzzle game was made popular by a Japanese puzzle company, Nikoli. It became a hit internationally in 2005 and never looks back since. Many online Sudoku websites, "How To Sudoku" books and mobile applications were spawned from this simple yet intelligent number game.

In case you are still clueless, Sudoku is actually a simple 9x9 grid that is divided into nine 3x3 blocks. The rule to play is also very simple (yet it will test your reasoning and logic sense). Usually, some numbers will be provided upfront, the objective is to fill the rest of the remaining grids with numbers only from 1 to 9 in a way that no number repeats itself in any block, column or row. 

The difficulty levels of Sudoku are determined by the following:

1. What numbers are provided upfront
2. How many numbers provided up-front and
3. Placement of these numbers?

It is a fun game that can be played individually or with a group of friends (the one completed the grids in the shortest time will be the winner). So, are you ready for a challenge to test your number quotient? Check out the free sudoku online.
