This expansion was the 2010 Christmas postcard from the designer and released again in standard punch tile form as part of the Brettspiel Adventskalender 2016.
A player wins the Christmas Gift by filling the 6-space enclosure. (Players playing with other postcard expansions must choose which bonus tile to take). Owner must place all their discarded tiles in the enclosure with the Christmas gift. Those tiles remain there until the end of the game (no remodel actions allowed!). Tiles should be stacked. At the end of the game, owner of the Christmas Gift scores 1 point per tile present in enclosure.
Only allowed to be played on Christmas!
