I'm not amazed. It was wrong for me. I think this (by the way, did you notice it was a 7-up ad?) takes something simple and disguises it as complex. At the front end you start with any 4-digit number-- why, that's 10,000 possible numbers! But really, it is guessing one out of nine (you pick one digit and it can't be a zero.) ----- Original Message ----- From: "Miguel Motta" To: Sent: Monday, May 09, 2005 8:38 PM Subject: Mind boggler Totally non-musical related BUT what a mind-boggler! Try it... Follow the instructions carefully... on the last page where you're asked to type in your reply just do so as it doesn't cursor... you'll be amazed (and if someone can come back with a logical solution....) http://digicc.com/fido/ Cheers, Miguel
