Etymology of "Horsengoggle"

(Note to the dyslexic: be sure NOT to confuse this with “Google”.)

Horse and goggle –> Horse ‘n’ goggle –> Horsengoggle

There is a Wikipedia entry for this hand game: a kind of rock-paper-scissors, or drawing straws for a group to pick a single ‘winner’.

My question is, within the context of this game, where did the name come from?

My best guesses:

• A jockey on a horse who wears goggles running around a track like the circle of people?
• The goggles that a horse wears, like blinders?
• People goggling (gaping) at a horse race?
• Horsing around and goggling the results?
• Somehow related to the dice, poker, and basketball games called “horse”?
• ?

The game may have started in Germany, or from an American whose family came from Germany, so maybe “goggle” has some alternate meaning lost in translation?
