I meant to post this a while back, but it lay in the ‘to sort’ area of my bookmarks for a while, sorry. Anyway, next time you need to keep someone quiet for a while, be it a long car journey, the motor mouth in your local pub, or just your own brain cells, head on over here. A simple little wiki page on puzzles, the discussions tab is also worth popping over to, especially if you want to see how your answers compare to others.
