The coin must be easy to split (most likely just glide) and the coins must be coins on all sides
the nearest you would get to this would be a slippery ], some come in a locking variety.
other than that your looking at a triple or quad threat which would have a begining a middle and an end if you get my drift.
most splits have enough power for you to add a regular coin to the middle which if flashed quickly would allow you to devide into two then again for three.
