This season's challenge involved collecting yellow stones and stacking them on the foundation plate to earn points. However, the robot had to be able to squeeze under a “skybridge” in the middle of the field, separating your building zone from your collection zone. Points were earned for moving the foundation plate, stacking the yellow stones, and parking under the “sky-bridge” at the end of the game. Extra points were given for placing a custom team-designed capstone at the top of your tower as well as autonomously completing tasks at the beginning of the game.
