2005: Triple Play
For more images of the 2005 game, visit the gallery.
Triple Play is played on a field initially set up as illustrated in the figure bove. Two alliances - one "red" and one "blue" - composed of three teams each compete in each match. The object of the game is to attain a higher schore than your opponent alliance by placing tetras on or into goals, getting three goals in a row capped with tetras, and/or having all three robots on an alliance in their end zone at the end of the match.
A tetras is worth 1 point if contained in any goal and 3 points if stacked on any goal at the end of the match, for the alliance of the corresponding color. Any row of three goals owned by the same alliance at the conclusion of the match is worth 10 points for the alliance. There are eight possible rows. All three robots of the same alliance in their designated end zone at the conclusion of a match is worth 10 points to the alliance. A robot is not considered in the end zone if it is touching the field outside the defined end zone border. The tape line designating the end zone border is considered "in" the end zone.
