The team with the highest score at the end of round two went on to the final challenge of the game, the obstacle course (renamed theSlopstacle Course for Double Dare 2000). Regardless of the outcome, both teams kept the money earned, with $100 as the house minimum ($200 on Double Dare 2000 and $500 on the Fox version of Family Double Dare).
The obstacle course consisted of eight obstacles which had to be completed within 60 seconds. Each obstacle had an orange flag either at the end of or hidden within it. One team member ran the first obstacle, then passed its flag to his/her partner (or the next team member in line on Family Double Dare and Double Dare 2000), who then moved on to the next obstacle. The team continued to alternate in this manner until they completed the course or until time ran out, whichever came first. For safety reasons, team members were given helmets and elbow/knee pads to wear while running the course.
The team won a prize for each obstacle completed, escalating in value up to a grand prize for completing the entire course. On the original and Super Sloppy versions, the grand prize was usually a vacation or a scholarship to United States Space Camp, and each member of the team received identical prizes. On the Fox version of Family Double Dare, as well as the first season of the Nickelodeon run, the grand prize was a car. In 1992, the prize was changed to a vacation; however, the family that won the tournament held that season had the chance to run the Obstacle Course for a car.
On the Fox (1988) version of Family Double Dare, the seventh obstacle offered a cash prize that was worth a different amount (ranging from $2,500 to $5,000) on each episode.
