"Working in teams, the castaways must first traverse a water obstacle course. Once all three members have reached the end of the course, they must retrieve one of three balls. They must then work together to move the ball through a maze, using just their body weight to move the ball. The first team to get all three of their balls through the maze wins." ~ @SurvivorWiki
