This mini expansion replaces one random card in each row during setup. Each individual card only indicates the row or column where a treasure or curse can be found. Only by finding the pair of special cards can you uncover the exact location of a treasure or curse; the pair will tell you the row and column of the item — the intersection of the row and column is the location of the item.
Because these treasures are harder to find, each one has a value of 36! But beware, these cards also introduce an extra curse introducing the possibility of a fifth cursed location! At the end of the game, the new treasures are awarded as in the base game (evenly split between the surrounding players).
