MAMEWorld Forums - EmuChat - Re: Identify this Bronze Age game

I have never heard of this one and didn't find any info in my source. It looks like it's from 1974, however, and I don't have many sources from that early.
It wasn't mentioned during Jerry Koci's testimony in the Bally case that I recently posted about (he mentioned every other known Chicago Coin video game).

I do, however, have a guess as to what it might be.
One of the games is called Thumper Bumper.
When I talked to Larry Hutcherson at Exidy, he said their first game was called Thumper Bumper and seemed pretty sure of it.

My other sources show their first game as Hockey/Tennis, followed by something called Sting (which I originally thought was another name for TV Pinball but it looks like it was a separate game). These games were released only on the west coast because Exidy hadn't started distributing nationally yet.

When I talked to Pete Kauffman he said that he didn't think they used the name Thumper Bumper in the released version.
Hockey/Tennis (or Thumper Bumper) was a Pong game that used colored overlays.

Given that Chicago Coin was licensing games from Exidy at the time (they licensed TV Pinball and Destruction Derby, which they released as TV Pingame and Demolition Derby), that Exidy had a game called Thumper Bumper, and that it looks like Blitz used colored overlays, I'm guessing they licensed this from Exidy.

It's still not entirely clear to me what the relationship was between Hockey/Tennis, Thumper Bumper, and Sting was - especially since I've never seen pictures of any of them.
