Can someone help me find a question about a nuber guessing site?

Question

I saw a question the other day where there was a trick using 25 numbers and the site would guess the number you are thinking of. I wanted to show someone else to see if they could work out how it was done also. It used colors and number groupings to work it out. The final page revealed three doors and the number you thinking of always ended up behind the door. It had to because there was only one number it could be from the colour/group combinations.

Anyone remember seeing this?

I think it was posted in this section - although I don't know why?

Answer 1

I remember seeing something on TV as a child, where you stuck your finger on a numbered box on the screen, did things the magician told you too (move up one if your number is odd, that kind of thing) and at the end he knew what number you were on.  Obviously, regardless of the number you started out with, everyone ended on the same number.

Answer 2

I have seen something similar if not the same thing.  And, yes, it is rigged such that there is only one possible number that goes with the color door.  I would have to see it again to recall exactly what the trick was.  Needless to say, it doesn't have any special powers to read your mind.
