Yes I've played it years ago. I think the national or world championships are still in NJ.
There was another table like that in the 1950's in most bars in NY. It was called Q-Ball. It had only one wood mushroom. I wish I could find one in good shape now. The great thing is you only shoot from the front of it, meaning you don't need anywhere as much room as a 3x7 pool table. I think a company makes one now out in CA or WA. I believe it's called BarBilliards. Johnnyt
