Simple algebra...
Call the 2 digits x and y...
the number is then 10x+y...
If you subtract the sum of the digits (x+y) you get 9x
which is guaranteed to be a multiple of 9...
Check all the symbols that are multiples of 9 (9, 18, 27, etc.) and you will see they are all the same!

First of all this game does not work for any number with the digit zero for its first digit. (ie 07 since 0+7 = 7, 07-7=0; and the number options never indicate a zero as a valid answer). What you are viewing is a trick/visual deception. Assuming that we are not using a single digit number case (anything from 00-09). Any two digit number that is subtracted by its sum of digits will produce a number that is the multiple of the number nine. So if you take 88 and subtract 16, you get 72 and 72=9*8. Or take for example, 17 and subtract 8, you get 9; which is a multiple of itself. Althought I cannot prove it mathematically on this forum, yuo can infer that any multiple of 9 will always be the answer.
If you look carefully at the grid in the end where you choose the picture for the number, all the numbers that are multiples of nine have the same picture (9, 18, 27, 36, 45, 54, 63, 72, 81). Hence, whatever number you choose and sum you end up with, the picture will always be the same for every number.
Doan let the spooky graphics scare you.

I just played it, and now I know how it works, well my sister does. Everytime you will get a result that is a multiple of 9. Each time the symbols change on the numbers.
Now if you play agin will you can see that all the numbers that are multiples of nine will have the same looking symbol.
Example: 52:: 5+2 = 7 ::52-7 = 45::
45 is 9 x 5
12:: 1+2 = 3 :: 12-3 = 9::
9 Is 9 x 1
Try any number sequence and see that it is a multiple of 9.
All multiples of nine have the same symbol

It is a common trick. A two digit number can be represented as 10a+b, where a is the first digit and b is the second digit.
Step 2: subtract the sum of the digits: 10a+b - (a+b) = 9a.
So your answer will always be a multiple of 9. (9, 18, 27, etc.)
Each time you run the game, look quickly at the symbols. The symbols change, but the same symbol is ALWAYS used for the multiple of 9, so you will always be outguessed.

Just pick a two digit number like 77. Add the two numbers together which is 14 and subtract it from 77 which equals 63. Find the number 63 in which has a symbol over it. Stare at the symbol for a while and you're done.

Okay, all of the correct answers will be multiples of NINE. So, any multiple of nine will have the same symbol...sometimes they will throw in the correct symbol a few other times to throw anyone trying to solve the game off the scent, but the correct answers are all:
9, 18, 27,36, 45, 54, 63, 72, 81, 99
get it now? I had a good deal of trouble trying to explain how this game works to my best friend thanks to your question...she's a math freak and she said that there cannot possibly be a perfect equation like that....yeah right.
SO....there you go. Have fun fooling your friends into "guessing" their symbol along with the computer.

edit....yeah, freaky. Ok, so here's how it works.
The answre you get is always a factor of 9. There would only be 9 right answers and the 9 answers divisible by 9 will always have the same symbol, making it correct each time. (I played this a couple of times and noted that it DOES change the symbol of the correct answer each time, but it IS always the factors of 9.)

it goes by 9 so on 9 that is going to be what it will be and then 18 is the same as 9 and 27 is the same as well as 36. only a selected amount of numbers will actually be able to come out of their. all divisible by 9

the symbols change and are repeated.... not matter what you pick (say 10-19 you will ALWAYS get 9) (say 30-39 you will always get 27). Therefore, with the symbols repeating no matter what number you pick you will get only a few final numbers(which all will have that same symbol)

Yes... nothing freaky on it...
It always brings back the number 9 figure based in the mathematical approach they make you drive you mind through...
At least for me it was like that, unless my brain stocks in number 9....
