Lots of highly animated ads that are distracting and kill performance. Dragging pieces stutter while animations run. Because this causes pieces to jump along you can be fooled thinking a piece has locked into place when it hasnt. Im very disappointed. Also, often when I try to drag a piece some adjacent piece that I am not even touching will move instead. This used to be a fun game, but the frustration level is rising above the fun level.
