This one is my all-time favorite! When it was freshly introduced to the Indian puzzle-lovers, I used to do it daily in all the newspapers I could get my hands on! I remember I was in Mumbai for a friends wedding, back in November 2005, and his brother enjoyed doing Sudoku as much as I did! LOL! It was a daily competition between us as to who would get hold of the day's newspaper first! :-p
Well, I'm sure all of you must already know the rules of this game, but just in case, there's a newbie in the block...
You've got the fill the numbers in the empty cells in such a way that each row (horizontal), each column (vertical), and each individual '9 x 9' box (enclosed within the bold border) contains all the numbers from 1 to 9... ONCE EACH! Obviously, if you repeat any number, you're sure to miss out on some other number then!
Have fun then! Oh and you can change the difficulty level from the drop-down given below the board!
And here's more in Games!
