I faced one of them, (I had a box of 10, originally) after taking a short, 4 hour class at The University of North Carolina by a noted re-facer.
I figured I had little to lose.
It plays. It does not play very well, (because I really still do not know what I am doing, but am decent with symmetry), and, of course, "playable" and "enjoyable" are two entirely different animals.
Interestingly, these were reportedly made by Babbitt for Bay.
