Japanese Sudoku, free to play on the web

I'd nearly forgotten all about this game, Sudoku, until I saw Joe Grossberg blog about one that's freely available to play on the web at www.websudoku.com. The screenshot to the right shows the result of my lunch hour, today.

Update: If you're looking for another online place to play, check out Iron Sudoku, where a new puzzle is posted daily and you can chat in realtime with other people who are playing the same puzzle. It's very nicely done, although the interface might be a little awkward at first, you do get used to it and it's very playable.
