From the Queen Games and the Gamefest Homepage:In the valley of the Indus, traces of the ancient Harappa culture are to be found. Two to four expedition teams are ready to try to secure the most promising sites in the digging field. Each square on the game board contains valuable finds. Each team would of course like to occupy the best sites, and then dig away in peace and quiet. Players use their archaeologists and assistants, while the workers ensure that the digs are supported. The game is different each time, since the board consists of 7 large and 7 small board segments that are combined differently each time, leading to different dig configurations. - BoardGameGeek
