I played on one of these about ten years ago. Never played on it before, and had a lot of fun. People I was playing thought I played on it all the time when I started running racks and making three rail banks around the corner in the side pocket!
I have never seen that kind of table before but would love to give it a try! Where was it located? I know when I played on the L shaped table, some incredibly interesting shots were able to be played, shots that would never be possible on any other table. I can just imagine what could be done on this one!
We have one of those "z" shaped tables at a strip club in Portland, OR. I was just starting my comeback when I played on it so don't really have a good feel for how it played. It wasn't level, I remember that. So many pockets...
It's definitely a novelty item.
When I played on the L shaped table, all that worked for me was the mirror system, angle in equals reflected angle out. Guess the same would work on this z shaped table, just a few more "reflected angles" to account for.
