Gaun Khane Katha is a game in which one person asks a tricky question and another person or group tries to answer it.
The same answer can be correct for multiple questions as per the logic given for it.

It is basically a traditional quote of Nepal and it is said that one used to place a Gaaun (village) as a bet in this game, hence the name is Gaaun Khane Katha ( village eating game)
