Last I checked there were 3 in the entire United States and nobody was selling. I doubt you will find one of these. I tried for 4 years.

Yes, there are 12 known in the world (they made more, but many were trashed). I said 3 in the USA. Maybe a couple of more were imported since I was looking, but certainly no more than that.
It is a game most people will never see in their lifetime, even if they try. Zankor is another one.

Joe sent me a video link awhile back after he finished restoring his Spooky. Here you go guys, check it out.

Yes, its a translite I made complete with reverse lettering and masking on the back. David hosts all of the translites I worked on in 2007.

I understand they helped several people that broke backglasses or were missing them. The Robot translite was the first one I had printed on the translucent vinyl and it was so nice having something in the backbox (my robot was missing a backglass when I got it).

I don't think Joe ever found a Scramble backglass for his other rare game. I never found source material to help.
