Ok, warning, if you don't want to know how it works, or want to work it out for yourself, stop
reading now. . . . . . . . . . . . . Firstly, the maths involved is quite simple. I'm not sure whose
law it is, but it all works around multiples of nine. For some reason, subtracting the sum of the
two numbers from the original number will always give you a multiple of nine. Have a go, it's true.
Next, look at all the multiples of nine in the table to the right of the ball (90 and 99 can not be
achieved with doubles). They all share the same symbol. Hence, whichever multiple of nine you end up
with, the symbol will be the same, and the correct symbol displayed in the ball.
"But hang on, each time I do it, I get a different symbol!"
This is the sneaky bit which really makes it work. Once you've clicked on the ball, the table of
symbols is wiped, and when you click 'Try Again' a new one replaces it. The new table has a new
symbol for all the multiples of nine.
