Quick Sudoku

I'm not sure if you have seen these Sudoku (soduku?) puzzles that have become all the rage recently. I must admit they passed me by for a while, not being a crossword puzzle kind of person.

While waiting at the airport the other week I gave one a go, and got quite into it - I managed to do a moderate and a diffucult one and was feeling quite pleased with myself.

You basically need to fill in a 9x9 grid with numbers, so that each row only contains the numbers 1-9 once, and each 3x3 box can also only contain 1-9 once. It sounds easy, but can be quite tricky to complete.

But they do tend to take a lot of time to do, and I am quite an impatient person. So, I have devised my own version. So without further ado, ladies and gentlemen.... I would like to present for the first time: Quick Sudoko.

Answers on a postcard, or the back of a sealed envelope please....
