Except inverted. Left spin on a ball makes it go right by Magnus. Left curl makes a stone curl left.

I curl and play pool, so I've come up with reasons for the difference in my head.

The slower turning side creates more friction because it grabs the ice, the faster side glides over rather than grabbing. This is obvious when you intently watch as the curl picks up at the end of the shot.

QED, dunno why a bunch of non-curlers wrote these articles they should just curl.
