The general wisdom, repeated almost verbatim in the sites dealing with it (from BGG onward), is that "it is of African origin", some put it in relation with Neutron, and then nothing else.
For instance, English Wikipedia, not only does not have a page about it, but apparently has no mention at all of it whatsoever in any page!
Does anybody know anything reasonably solid about Bobail? When it became used in Europe? who/when/where brought it from Africa (if...)? Which is exactly its relationship with Neutron? (and which game really influenced the other?). And so on.....
TIA for any detail!
