The game is about attacking the settlements of other vikings, sink their viking ships and plunder their gold. To win, one must collect 2 golden treasures on one's own settlement or sink all competing viking ships. [translation of box cover blurb]
Each turn, a player rolls two dice and moves either one of initially 7 ships a number of squares equal to the sum of the dice or two ships each according to one of the dice. While moving, ships must avoid squares with obtacles or islands and other ships, except on the final square where it can sink another player's ship or enter an island. When sinking a ship with a gold treasure or entering an island with one, a ship captures the treasure.
