We used the phrase similar; as Olly Olly Entry, after the seeker would give up the search for hiding individuals, to re-call all players back to the starting place. This place was called gouls; as I remember it. To this day I do not know how to spell it. But, as I think back, it may have been a meaning or pronounciation of GOAL. I am NOW sure that Olly Olly Oxen Free, was definitly was the true phrase of mis-pronounced Olly Olly Entry.This memory of the game hide and seek was played in Methuen, Massachusetts. This Town was also an English settled area, founded by The Searles, Nevins,and Lowell families of Royalty.However I do not think or know if olly olly oxen free is/was originated there in relation to hide and seek. Hope this helps. My question on the subject still remains unanswered.
: There's bound to be a book on children's games. What was your original question, the meaning of "olly olly oxen free"?
: I have a really neat book, "American Children's Folklore: A Book of Rhymes, Games, Jokes, Stories, Secret Languages, Beliefs and Camp Legends for Parents, Grandparents, Teachers, Counselors and All Adults Who Were Once Children" by Simon J. Bronner. (August House, Little Rock, 1988.) Catchy title isn't it?
: It doesn't have what you're looking for. But, like I said, I'll bet someone has written a book with all the old games.
I've seen this before - the phrase is probably derived from the English ear hearing the German expression "Alle, alle alle sind frie" which means "all are free" - the game of hide and seek is over.

Olly olly oxen free is a phrase used in children's games, which is generally used to indicate that people who are hiding (in a game of hide and seek, for example) can safely come out into the open.
Origin
The exact origin of the phrase is unknown, but etymologists suspect it is a childish corruption of a phrase that would have made more sense in the Hide-and-seek context; such as "all ye, all ye, oxen free!", "all in free", "out’s in free", "all set free", "All ye all ye outs in free", "All ye, all ye, outs are free", or "All the, all the outs in free"; or possibly a corruption of the German "Alle, alle auch sind frei", (literally, "Everyone, everyone also is free").
Use
The phrase can also be used to coordinate hidden players in the game "kick the can", where a group of children hide within a given radius and a "seeker" is left to guard a can filled with rocks. The seeker has to try to find the "hiders" without allowing them to sneak in and kick the can.
It's also used in the Halo novels as an identification code of the Spartans.
