Pretty cool Wendy. It did take me a couple minutes to figure out how it is done. I'll show it to my kids today. It should boggle their minds....




If I knew then what I know now then I would know more now than I know.

Thanks, furshur. It took me a little time, and ultimately it was a card trick I remembered that lead me to the solution.

My kids love math, so I'll be interested to see how quickly they realize how this works.

OK, I give. First I did it without any math. It was right a couple times and wrong a couple. Then I did it with the math - same result. It's weird when it was right but it wasn't always right.

OK, I decided to be more scientific. I tried it a few more times with the math and it was correct 5 out of 5. It missed 3 of 3 without the math. I am totally stumped.

It was right for me without fail. I've sent it to some friends and they say the same. I'll be the first to admit that I'm lousy at math, but math is half the key. I'm reluctant to post the solution here. I like to figure these things out for myself, and others may wish to do the same. Please feel free to PM me if you'd like though, and I will send you the solution.

OK, I see how it is done. But I don't want to spoil it for others. Don't post the answer, Wendy. It's more fun to be mystified.

Showed it to my son. He had seen it and had sat around with another friend and his friend's family and figured it out. Well I'm glad he had some quality time with someone anyway.

My pleasure, Dr. Mabuse. It was a hit last night at my house, too.

It was right for me without fail.

Well I figured out why it it was correct so often on the occasions I didn't do the math. And I must have been sloppy on the occasions I did the math and the 'mind reader' was wrong.

This is much better than the card selecting version I saw. Same principal though.

My husband played around with it without doing the math too. For him, that was the best way to figure out how it works.

I'm such a stick in the mud when it comes to following instructions, it never even occurred to me to try it without the math.

Being in discrete math, I just had to try to come up with a proof for this.

***WARNGING: below contains the answer to why it works***

Let x be an integer, such that x >= 10 and x <= 99.

Therefore the first digit which make up x can be described as:

d1 = floor(x/10) (the floor of 7.3 is 7, the floor of 8.9 is 8)

While the second digit is the remainder of this:

x = 10*floor(x/10) + d2 (quotient-remainder theorm, where d2 is the remainder)

d2 = x - 10*floor(x/10)

The sum of these two digits are:

s = floor(x/10) + (x - 10*floor(x/10))
s = x - 9*floor(x/10)

When this number is subtracted from the original x (as is described in the rules):

n = x - s
n = x - (x - 9*floor(x/10))
n = 9*floor(x/10)

Let the integer y = floor(x/10) (floor must, by definition, be an integer)

n = 9*y

Thefefore the final number n must be divisible by 9.

Why continue? Because we must. Because we have the call. Because it is nobler to fight for rationality without winning than to give up in the face of continued defeats. Because whatever true progress humanity makes is through the rationality of the occasional individual and because any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.
- Isaac Asimov

****More spoiler**** so don't scroll down unless you want the BIG SECRET revealed.











































Basically, per Ricky's solution, you get a set of numbers. The SAME symbol is assigned this entire set.

Also, just to confuse you even more.... the symbol assigned to this set cycles through a group of symbols.

Proof? Look at the number 9. Click the orb. Try again (and note that the symbol for 9 will have changed). Everytime you click the orb, the symbol assigned to 9 will appear.

Ignorance is preferable to error; and he is less remote from the truth who believes nothing, than he who believes what is wrong.
