i do, sudoku

I'm addicted to Sudoku. It used to be that a good crossword puzzle would satisfy me but now there's a bigger beast that has taken hold of my mind. It contains numbers (which I love) but no math (which I'm not particularly fond of) and a grid (like crosswords). It's a logic game. The object - fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. No repeats in the same row, column or grid.

Last week a "Tough" puzzle stumped me but since then I've completed 2 "Diabolical" puzzles with great ease.
