Opis w języku angielskim:
Post Office. Card Game is a game in which you will need to place cards covering some parts of the other cards in a way that helps you score the most victory points.
Every player has a starting Package card placed in front of them face up. Each round you take 2 Package cards, pass one to the player on your left and receive one from the player on your right. Then you place one of your cards on top of the already placed card(s) on the table, covering some parts, but not all of it. Your aim is to cover as many mice as you can, creating rows and columns with different types of packages.
At the end of the game, you gain Victory Points for rows and columns containing 3 or 4 different types of packages (one type cannot be repeated within a row/column) and lose Victory Points for each uncovered slot with a mouse. Whoever gains the most Victory Points — wins.
