That's creepy. Though it was wrong once out of five trys

That's the strangest thing ever. I did the sum wrong the first time and it still gave me the right symbol.

Is this one of those wiccan sites?

Hehehe, that's clever. Took me a few minutes to figure it out. That little formula you do to pick a number ends up with the same symbol no matter what you choose. Try it 3 or 4 times without clicking the crystal ball, and you'll end up with the same each time. Then when the list refreshes, you'll see all the symbols are shuffled around so they no longer match up to the same numbers, which is why it always ends up guessing a different symbol.

Sorry, us geeks ruined all the fun yet again. :)

Is that true? Is it always like a multiple of 9 or something?

Yep, multiple of 9 every time.

A similar kind of trick: http://www.img.net/magic/pickcrd3.htm

Well that one is simply a trick. No math, just 5 new cards that weren't there previously

Sorry irseg, but that theory just doesn't cut it with me. I still say it's witchcraft.

We found a witch, may we burn her?

She turned me into a newt!
