Feng Shui Ref in a game at a convention.

In this unique take on the trick-taking genre, cards represent the units attacked or defended Allied convoys in the North Atlantic throughout World War II. For each trick, the lead player selects a convoy that traversed either the Arctic or the Atlantic in a given year (1940-1943), then declares whether the battle will be fought in the air, on the surface of the ocean, or under the sea. He follows that up by playing a unit, either German or Allied, that was available in the chosen year and could fight in the chosen environment, and the other players subsequently either pass or play a unit that meets the same conditions. When all players have made their selections, dice (sometimes) are rolled and totals are compared to determine whether the Germans or the Allies won. The player who contributed the most to the winning team acquires the convoy as well as all opposing enemy ships, giving him both victory points and possibly an increased hand size. After twenty convoys have been fought over in this manner, the player with the most victory points' worth of convoys and captured ships wins the game!
