Vasa Regalis is a card game version of Vasa Regalis: The Maiden Voyage. Players are shipyard leaders responsible for the building of the Vasa Ship. At the same time, you want to keep as much material as possible to yourself but beware, if the ship sinks you may get the blame. The victory conditions are determined by the sum of all players' actions. If players add a lot to the ship, it will succeed but it is the player placing LEAST on the ship that will win. If, on the other hand, players add little to the ship, it will fail and the player placing MOST on the ship will win. The players start with cards representing goods at different values. Each turn, they may choose to place cards on the ship, inspect cards placed on the ship or replace own cards placed on the ship. When all four parts of the ships have been completed, the game ends and the ship is launched. The challenge of Vasa Regalis is to correctly guess how much the other players add to the ship. The unique mechanism of Vasa Regalis is the ambiguous victory conditions. The players can analyze the piles and draw conclusions but never be sure how to win. Should they add as much to a part as possible or as little as possible? They will not know the answer until the ship is launched but then it is too late to do anything about it.
