We return to ancient days, when man lived in caves and woman lived in adjoining caves and their language consisted of little more than grunts and gestures. Primitive though we may have been, we still dreamed of ruling over everyone else as leader of the clan!
In Ooga Booga players need to repeat a series of guttural noises, then add to the chain. At the start of each round, players are dealt three cards face-down and those cards remain hidden; each card shows a "word" and associated illustration – "Miti" for woolly mammoth and "Atrrr" for fire. The first player of the round lays a card in the center of the table, makes the noise, then points at another player, saying "Ha!" That player must add a card, repeat both sounds in order, then choose someone other than the player who chose him. Some cards have actions and add a gesture such as sticking out your tongue or pounding the table.
