I've gotten 3 wings 3 different times and I always play 3 coins at a time. As for halos, only 1 at a time. Now that would be nice!!! I don't even know anyone who had gotten 2 in a row, 2 in the same screen but not in a row.
Oh and I did take and print my screen to prove that I got them and the picture hangs next to my computer awaiting the next time I get them again. biggrinbiggrinbiggrinbiggrin
