From the New World Games website: A sneaky card game for 4 or 6 players Players will pick up and lay out cards, attempting to match four or five cards of the same value. If a player manages to do so, and secretly communicates it to his partner, they win the round. If the player is caught with four or five of a kind by the opponents first, his team loses the round. Each time a team loses, they get one or more letters. When they get enough to spell LOSER, the other team wins.
