Sudoku.
You probably know the basic rules. You are presented with a 9x9 grid such as the following, which is initially partially filled in with some characters, usually they are numbers 1-9:
You must fill in the remaining cells such that every row, column, and 3x3 box contains the digits 1 through 9, and the same digit may not appear more than once in any row, column, or 3x3 box. Simple!
The completed Puzzle is then:

Should you choose to immerse yourself into this puzzle cache experience, then like it or not, you will become familiar with twelve of my favorites. Oh, also I have been led to believe there are online solvers for sudokus. If that's your thing, then cool.
If you enjoy solving Sudoku's, this will (hopefully) be an educational and enjoyable journey. If not, then perhaps not. Either way you will likely end up with 9x9 grids pervading your dreams at night.
