Sudoku is my favorite brain exercise. I mean what other game can make you break your #2 pencil and throw the pieces across the room ?
Never have I played such a game that turns out not to be a game. It is more of an exercise in hurting yourself 
As you can tell I do not like the sudoku puzzles

If you have ever seen someones head staring down at a notebook looking thing with a pencil in hand… you may be staring at an avid crossworder… but, recently a new craze has been sweeping the country… SUDOKU!
WIKI says that Sudoku is a logic-based number placement puzzle. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9, only one time each (that is, exclusively). The puzzle setter provides a partially completed grid.
I can tell you from many hours of what I thought was relaxation… turns out, it was more like frustration… that, Sudoku is a great new addition to the games world.
