      SPOILER

      No matter which 2-digit number begin with, the end number you'll always end up with is a multiple of 9 (9, 18, 27, 36...)- and if you'll notice, the icons representing the multiples of 9 are the same. But the icon changes everytime you refresh the screen, so it looks as though you get a different result each time. Fun game though..hehe.

        it's strange as to why it always come up with multiples of 9,
        but this is what i thought:

        eg:
        for no.10: 10-1=9
        11: 11-2= (11-1)(you get 10) -1=9
        12: 12-3= [(12-1)-1] (you get 10) -1 =9

        as the LHS increases by 1, we subtract 1 more. thus we are able to reach the initial ans of 9.

        this goes on for 20-range (2 tens), 30-range (3tens), etc...
