I read all the stuff about not being able to control the outcome of the spin with the "stop" but I have my doubts. I spun the wheel 12 times today and observed. The first 5 times I did not use the stop feature. The last 7 times I did and hit "stop" when the gold circle was at the 12:00 position. EVERY time the gold circle stopped between 8:00 and 10:00. I won the gold prize twice, missed it by one stop the other times. Pure chance? If the result was predetermined then the gold circle's resting spot should be far more evenly distributed. Granted, it's a small sample size.
Feel free to have your doubts. Keep hitting that stop button when you think it is the right moment. Like I said before, every Summer Event there are some that can hit the stop button at the right moment. If you want to fool yourself I can not stop you.
