In this game, you try to run a successful ship-transport operation in the mysterious Bermuda Triangle. There is a track that runs round the board from port to port and you roll a die and move one of your your ships to reach a port to deliver the commodity required by that port. The prices offered by the ports change with each delivery, so you try to arrive when the price is high. There is a lot of scope for blocking other ships and for bumping them back to their last port. So where does the Bermuda Triangle bit come in? There is a mysterious cloud - a plastic construction raised from the board on a central column - which moves about the board and twists around above the ships. There are magnets on the underside of the cloud and on top of the ships, so ships can be picked up and moved or destroyed when the cloud passes over. Each turn, a player moves a ship and the cloud - usually trying to protect their own ships and attack those of other players. - BoardGameGeek
