Double Disc Court, commonly referred to as DDC, is a unique sport in that two discs are used in play at the same time.
Double disc court is a frisbee sport which combines quickness, strategy, and throwing ability. It is one of seven events contested yearly at the world overall flying disc championships and the most fun thing to do ever.
DDC is played by two teams of two players each. The courts are 13 meters square and 17 meters apart. You get one point for a throw that lands and stays in the opponents' court, or if an opponent drops your throw. Your opponents get one point if your throw touches outside their court. If you can arrange it so that the other team is touching both discs at the same time, you get two points. That is called "doubling" your opponents.
A common strategy for escaping doubles is for one player to tip one of the discs. While that disc is in the air, the other player catches and throws the other disc.
