A strategy game of placing trading posts and moving stacks of explorers, called caravans, along the path of a river. On your turn, you will pick up a stack of explorers, called a Caravan, and move it mancala-style by dropping the explorers one at a time off the bottom of the stack as it travels forward. Each explorer dropped on a space will earn money if there is a trading post of the same color on the space, so other players may earn money on your move. Drop an explorer on a river crossing, and it will wash downstream to the previous river crossing. Drop an explorer on an animal token, and the owner of that explorer will have a special ability. When a Caravan reaches the source of the river, the game ends and the player who has made the most money along the way wins. —description from the publisher
