In 2005, Team 604’s rookie year, the challenge was "Triple Play", a game consisting of pyramid structures on which teams place tetrahedrons (or "tetras") to rack up points for their alliance for that round. The pyramids are positioned in a three by three tic-tac-toe formation. Whichever side has the top-most tetra on a pyramid at the end of the round gains points for that pyramid, and bonus points are awarded for acquiring rows of pyramids with that alliance’s color.
