From the Box: "They shall mount up with wings as eagles" (Isaiah 40:31)...and Duel in the Sky This is a game of daring, strategy and chance. Two eagles circle, stalk and pursue each other until one swoops to victory. To hover, to dive, to climb, to soar is decided by chance and the cast of a die. Direction and distance is decided by the strategy and daring of the player. This is a 3-dimensional game that teaches in the simplest way: depth perception over a 2-dimensional playing surface. Contents: A large playing surface (cloth board), a die, and two cube playing pieces.
