I'm hooked on Sudoku!

While I was on vacation, my bro's gf had this puzzle book that she was working in just about every free moment she had available. Then my other brother would pick it up and start a puzzle after she was done. It's highly addictive and after they told me that there is a web version you can play, well...as they say the rest is history. What's this puzzle, you ask? Sudoku!

Here's a definition of the game from WebSudoku.com--

The rules of Sudoku are simple. Enter digits from 1 to 9 into the blank spaces. Every row must contain one of each digit. So must every column, as must every 3x3 square.

Each Sudoku has a unique solution that can be reached logically without guessing.

There are puzzles ranging from easy to evil! Head on over and have fun!
