I was reading this question about throwing a hook in Wii Sports bowling (which I can do), and it reminded me of the one time I was playing Kinect Sports Bowling with my friends and their child.
I'd never played Kinect Sports before, but I thought I remembered Wii Sports being a bit like real-life bowling, so I tried to do the same thing (basically, throw like I would if I were holding a real ball), and it didn't seem to work at all. Instead, I got what seemed to be a sequence of very straight throws: nice when I wanted to pick up the 7 or 10 pins, but not nice when I was throwing a first ball.
So I thought I would ask: what should I be doing to get my ball to hook?
