Level 475 is absolutely impossible, or it is rigged. There are 35 moves to free 14 bears, most of which are under 8 layers of ice. I tried it many times without boosters, and I consistently get 12/14 or 13/14, accompanied with the "Oh No so Close" message. My reasoning was, if I used Double Fish, then I could win with this slight edge. However, with Double fish, I got results like 8/14 and 10/14. I have been seeing this pattern over and over. Is there some sort of crazy alogrithim controlling the candies that fall down? I have spent many days and 15 double fish trying to beat this frustrating level.
