Build a house with playing cards. stack your cards carefully. for the walls: click on 2 cards of the same suit or of the same value. for the roofs: pick any card. the walls need to be supported by pairs with equal or higher pair value or your house will collapse. special pairs: pairs with a value of 20 can be placed on top of any other pair (even lower values). a pair with value 21 can be placed anywhere and will strenghen the walls directly below.
