Can't afford to go to a psychic? Don't worry, you can now have your mind read online

Ha! I tricked it! I didn't even add 2 numbers...just concentrated on a symbol

I did it twice. I added up the numbers, and followed the instructions... How does it know what symbol I picked? It worked both times!

Aargh! Forbidden by ratings check at work....

The first time it was wrong... The second time it was right... I double checked my math to make sure it wasn't human error... I kept the same original number both times? Hmmmm

:censor::censor::censor:!!!! That is queer!!!!! It doesn't work, though, if you just pick a symbol like someone did above!

It changes the symbol each time for the numbers, there is a math formula that gives you a certain group of numbers when you do that formula and it gives the same symbol to those numbers, but each time you refresh the page, those symbols change to a different one

It actually explains how its done. I pretty much figured it out. There are only certain numbers that you can get when you do the math, and the same symbol is placed for each of those numbers (see link above)...the "mind reader" knows the symbol before you even do the math!
