Tichu

Over 642 million Chinese play Tichu nearly every day! The goal of the game is very simple: just get rid of your cards.

Tichu is primarily a partnership game for four. The game comes with two complete decks of cards, so players may alternate playing decks when playing with four or play with larger groups. The groups, however, should not exceed 10 players.

From BoardGameGeek: Partnership climbing card game -- object is rid yourself of your hand. The deck is a standard 52-card pack with four special cards added. When it's your turn, you may either beat the current top card combination or pass. If play passes all the way back to the player who laid the top cards, he wins the trick and can lead the next one. The card led determines the only combination of cards to be played on that trick. So if a single card is led, then only single cards are played. If a straight of seven cards is led, then only straights of seven cards, etc. The last player out gives all the cards he won to the player who exited first, and the last player's unplayed cards are handed to the opposite team. Fives, Tens and Kings are worth points, with each hand worth one hundred points (without bonuses). The first team to 1000 points wins.
