In The Builders: Middle Ages, the cards represent buildings or workers. Players score points (and gain money) by completing the construction of buildings, while placing a worker on a construction site costs money. Each building has four characteristics (carpentry, masonry, architecture, tilery) rated between 0 and 5, and the workers have the same characteristics valued in the same range. To complete a construction, the player must add enough workers to cover the four characteristics of the building. Some completed buildings join your labor pool as they can be used to complete other buildings. As soon as a player reaches 17 points, players finish the round so that everyone has the same number of turns, then you tally points, with each completed card having a point value and each 10 ecu being worth 1 point. Whoever has the most points wins.
