The object of the game is to collect 4 pieces of treasure from the Treasure Chest.
To this end, players have to move their ship from a dockside towards the island where the treasure is. They do this by rolling up to 4 colored dice. Each player rolls as many dice as there are players each time it's his/her go. Each player moves their ship according to the number on the die corresponding to their ship. If a player lands on a place next to a plank, the other players must shout out "Walk the Plank" before the dice are thrown again. If they succeed in this, the player concerned must go back to the start.
