Su Doku An Amazing game

Today's topic is on the number game Su Doku. Apparently this is an ancient Japanese game (Su means "number/digits" and Doku means "singular").This game has a square grid of 9 rows X 9 columns ( which inturn has 9 3X3 blocks).Numbers have to be placed in the grids in such a manner that each row, column and 3X3 grid contains unique numbers ( 1 to 9).Replication of any digit is not allowed.Each puzzle has one and only solution.

Though this game deals with numbers, this deals purely with logical and analytical skills.It enhances a persons lateral thinking and creativity.
I have been solving this puzzle for the past 1 month and it really honed my lateral thinking skills.

Some of my learnings are:

1.Look out for the solution beyond the scope of the problem.
2.Never overlook those hints which are not so popular.They actually show the easiest path for the solution.
3.Keep trying until the solution is arrived at. for all you know every problem definitely has a solution.
This is really an interesting game.Try your hand on it.
