@Anomynous I see you were able to activate the mechanism normally in the video. However, every time my B stepped on the mechanism after pushing the first ball, it wouldn't work, so I needed to use an extra autopilot to win.
Like @delator77, I thot I had used a shortcut, but had actually won as intended. Well, bowl me over...the 6th ball is a red herring? I'm not accustomed to that from you; I didn't expect it. Shud'a known with this group... expect the unexpected. So, I actually spent time & gray matter trying to find the purpose of that ball, duh. Regardless, much fun was had.
