Mind Reader, can't see how it works - try it
 

Hmm...I can usually pick these things but this one, I'm stumped. I have no idea how it knows the answer. Can anyone else figure it out?

It's because the only numbers possible are multiples of 9 up to and including 81, which if you'll notice all have the same symbol associated with them. Neat parlor trick, though.

Oh, ok. Makes sense now but it's still pretty amazing. I recommend it to everyone.

It's not really all that amazing; it's basic manipulation of numbers.

Well it's the best trick I've seen online anyway.

This thing is ancient, and the maths is pretty obvious...

I wasn't really that impressed with it. Once I saw all the numbers that had the same symbol as the number I had, it wasn't that hard to figure out. Meh.

I remember seeing the same trick some years ago. Rather than symbols, they directed you to a numbered column where your final number would be, and it would predict the column number instead.

Simple math, but fun for once.

Yeah, it's pretty easy to spot if you look at the pattern.
11-> 11 - (1 + 1) = 9
12-> 12 - (1 + 2) = 9
13-> 13 - (1 + 3) = 9

and so on....

once you see that, it's obvious why it works.

It is simple math, but I'm sure most of you saying this were stumped by at it one point.

Anyways...

I found a flaw.

I used 10. 1 + 0 = 1. Yes, it comes up as 9, but it wasn't the symbol that was there.

Also, the symbols change each time you click that globe thing.

the symbols change each time to make it seem more random. but on any one chart, all the multiples of 9 have the same symbol. well all mutiples up to 81 (you can't get a higher result when starting with a two digit number).

ye gods, i hate math. it's useful (and interesting to use with certain tricks) but just plain boring to learn.

Okay, you missed what I was saying. I said the symbol for the number 9 on the large chart was NOT the one I got when I clicked the crystal ball. The symbol next to 9 was one thing, but I got another.

Maybe it wasn't a flaw, but a glitch.
