Springboard (or Slinging) refers to the strategy used in team games, typically in Age of Empires II, involving two roles, a spring and a springboard. The player who acts as the springboard essentially launches the spring from the Feudal Age onwards through the Market exchanges and use of tributes. It allows the spring to reach the Imperial Age quickly and deploy vastly superior units against the other team. Variations of the springboard are the rushing springboard, in which the springboard simultaneously coordinates a rush, the three person springboard, which has the third player rush the opposing springboard, and the dual spring, which has two springs and two springboards.
