(See cadga)

Originally, I entered a typo on the Arabic result: I had "iiajib" instead
of "iajib" for the actual Arabic word (transcribed without Lojban
conventions) "yajib". With the typo ("iiajib"), cadga won; fixing the
typo to "iajib" made zgadi win.

However, changing Hindi (non-Lojbanic transcribed) "Chahiye" from "caxiie"
to "caie" (which is a somewhat large change, I understand, but it is not
utterly unreasonable), with or without changing English "should" from "cud"
to "cad", makes cadga win again.
Making the Hindi "caxie", though, makes zgadi win, regardless of
English's "cad" or "cud".

Overall, I think that I like zgadi more, but the result is so closely
tied to the etymologies and transcriptions used that I do not see it as a
clear victory solely by these reasons. I guess that usage will decide.
