Err, actually, it is. If you see commercial's 1-on-1 description, it tells you that it teaches the riffle force, along with the click (snap) change and some variations of it.
So yes, it is a riffle force.
Although I'm quite sure that you could cut a playing card in half and put that under the card you want to force... should look a bit cleaner from the side, and stop on the card you are trying to force.
