Bird House

Use a standard deck of playing cards.  Each round you deal a certain number of cards to the players.  The round also dictates what is trump.  The players guess how many tricks they will take starting to the left of the dealer.  Those who guessed correctly get 10 points plus the number of tricks they took.  If a player doesn't get their correct number of tricks, they get a zero or "bird house".  The player with the most points wins.
