Just picked up my third pinball machine this weekend. It's a nice EM from Gottlieb, Card Whiz. I've been playing it all weekend and my dad even came over and liked it enough to keep playing a few games on it. He doesn't really care for my "newer" ones but this one seemed to be OK for him.
It's a pretty basic game where the goal is to knock down all of the drop targets (bigger points for getting jokers first) but it's harder than it appears. Despite the simplicity it does have that one more game thing going for it though.
I think I might be picking up a couple more of these older game here soon and getting on with starting to build my own.
