The 2005 FIRST Robotics Competition Game, Triple Play, involved collecting tetrahedron shapes, known as tetras, and placing them on top of tetrahedral goals. The 2 minute and 15 second game had 2 periods: a 15 second autonomous period and a 2 minute drive team-controlled period. Alliances had to cap green Vision tetras and drop hanging tetras in order to obtain extra scoring pieces. Tetras underneath goals were worth 1 point, and tetras capped on goals were worth 3 points. Alliances owned goals when their color tetra was topmost on the goal, and 3 owned goals in a row were worth an extra 10 points. Robots could end the game in their alliance's end zone in order to score an extra 10 points.
