Deutschland braucht Kolonien

Trivia game with questions based on the German colonies until WWI.
-
There are six different maps showing German colonies/Africa. Each player chooses one to play with. Then, 78 cards are shuffled, and players take turns answering questions from the deck. If a player knows the correct answer, he gains the card. The player with most cards is the winner.

Each set of the six maps shows a nice puzzle on the backside.
