Linq

From BoardGameGeek:

Part word game, part bluffing game, part strategy game, LINQ is a team game in which you don't know who your partner is! Each round, two players will have cards with the same word on it, while the other players will have bluffing cards. The object of the game is to find out which two players have the same card - that is, which two players LINQ - by listening to the clue words that all the players give. For example, if the LINQ word is blue, a player holding that card might say ocean. A player who is bluffing might follow by saying shell. It's not yet clear who has the LINQ, until the other player can describe blue in a different context. After round one has been completed, players can guess who they think has the LINQ, or pass on guessing until after round two. When the LINQ is revealed, players earn 2 or 1 points for correctly guessing after, respectively, round one or round two. (The two players who are LINQed score only if they both identify one another.) The first player to score 10 points wins. It's a unique game in which you play as an individual but must rely on your partner - if only you know who that is!
