The Danish city of Copenhagen is traversed by canals and harbors, and part of it — ""Nyhavn"" (New Harbor) — is known for the colorful gabled houses along the water.

In the game Copenhagen, players design new façades for these houses so that they fit seamlessly into this beautiful harbor setting. By using the cards on displays, players will receive the corresponding façade polyomino tiles, with which they beautify their houses. Overbuilding certain spaces and floors gives additional skills for the rest of the game. Floors that consist of a pure window front are particularly rewarding and give the players many points.
