The taba game[1](Jogo do Osso, in Portuguese) is an alternative name for knucklebones. It is a very popular game played by the gauchos of 19th century Argentina and Rio Grande do Sul. The game originates from Greece.
The game is played in a field where the taba or talus bone is thrown to the air. Upon falling the people making bets guess if it will fall upward (suerte) or backward (culo).
