I don’t mean to brag, but at Dave & Buster’s one night I was able to score 8 out of 9 50’s using the bank method (my first shot was a 30). I actually drained the machine of tickets, and had to wait for the manager to come out and give me the rest.
I have never been able to replicate that, or even come close, but I do normally get pretty good scores (300 avg is probably about right) with the bank.
I didn’t realize that other people had written articles about the bank shot. I figured it out after watching a coworker’s 7 year old rack up about 350 points by wildly flinging them, most of which went off the sides.
A couple of years ago a laudromat near my apartment was selling off their video games and skeeball machines. IIRC, the videogames (standup arcade systems) were about $500 -$800 (I bought their Tempest for $600) but the skeeball machines (lanes? ramps?) were something like $2000. I was quite shocked at that, especially since these ones in particular sucked, they were really short, like about a 6 foot total run.
I just checked, and there are actually a couple full sized ones on sale at ebay for a lot less than that.
