Prehistoric people were fishing, hunting and gathering during their wandering. It was important to carry as few things with them as possible in order to move easily. They couldn’t speak, but Dudab was one among their primitive words meaning sorry. Lead everybody else by the nose, and keep ahead of everyone.
When it's your turn in Dudab, you can choose one of the two possibilities: lay down a card or draw a card. Then the next player's turn in clockwise order starts. Players need to collect as few cards and as few victory points as possible. For this aim, they have to be very tactical, and say "Dudab" with proper timing. The player who can lead everybody else by the nose and collect the fewest victory points wins.
