When you take a two digit number and add the two digits together, and then subtract the total from the original, the answer is always a multiple of nine

Take: xy
Add to get x+y
The original number really is 10x + y, as the digit to the left represents 10's
Subtract (x+y) to get 9x.

If you look at the digram all the multiples of 9 have the same symbol, so they're "always right"

It uses the last item your mouse cursor was over as the "guessed item".

Every possible result is a multiple of nine...

Any two-digit number can be expressed as a*10 + b. For 73 a=7, b=3...
The puzzle requests that you subtract the sum of a and b from the number, a*10 + b - (a + b), which becomes a * 9 if you reduce it... therefore it's a multiple of nine...

Also...

Every time you refresh the screen the symbols change (to confuse you.)

Something like this was posted before as far as I remember.

The thread went on for about 3 pages of people freaking out until someone finally figured out how it was done. I was one of those ignorent plebs

i got it working once but it just "guessed" the last symbol my cursor was on

It works every single time. If it doesn't work for you, you are doing it incorrectly!

I posted how it works above. It is maths, and is infallible...
