This was interesting..

Its the Sudoku.

Having a got a good link the other day, I started trying to solve.

If you have not heard, which is unlikely, its a puzzle. Its a game that needs bit of logic and patience. Normal game is a 9x9 matrix which is sub-divided into nine 3x3 matrix. The objective is to fill the numbers 1-9 in each cell in such a way that each 3x3 matrix and each row / column will not have any repetetion. Generally the puzzle will be given insuch a way that there is a solution and only one solution which u can reach by logic and not by guessing.



I had already heard abt the game and knew the rules, but just a beginner. Created a login and started trying. I got a couple solved and got excited. And there is this puzzle which I was sure that it was having more than one solution. I took snapshot at each stage to proove to the providers that I have found this out. After a lot of painstaking work, I eneded up finding that I was wrong. I lost the sleep for nothing. :)) But it was fun..

This was the site where I was..

Interstingly this game has a long history but got popular in Europe recently thanks to the work of Wayne Gould (born 1945 in New Zealand) is a retired Hong Kong judge. He saw this game accidently in Japan and got addicted to it. He worked on it and developed a software for creating the puzzles. He ditributed it for free to the UK Newspapers and it caught up like that..
