After a month in Jamaica, it is all down to the final challenge for the $150,000 Chili's dollars! Mark, Colin, and Jamie are going head to head with Lori, Ruthie and Ellen to see whose going to win the Battle of the Sexes. With their losing streak over, the ladies are confident that they have a chance to win... Each team is given a block puzzle as a clue for the mission that is to come. The ladies figure out the puzzle but the guys can't and Mark hopes this isn't a bad sign. After they receive the phone call with details, the teams arrive at the competition course. The game is called "It Takes 3" and will require each trio to work as a team in order to win. The first part of the course is the tri ski slalom, followed by the block-by-block brainteaser, and then the ropes course. No member can advance to the next phase without every person on his or her team completing the obstacle. The horn blows and the mission begins... The guys quickly get in a groove and finish the ski-slalom first. While the ladies are still struggling, the boys get to the block-by-block challenge but can't seem to figure out the mind game. The ladies finish and quickly complete the brainteaser leaving the guys in their dust. The boys continue to struggle as the women have moved on to the ropes course until Colin decides to examine their completed puzzle and copy what they've done. The men don't feel bad for doing what many would consider foul play. The teams are now tied in the last leg of the competition. During the first part of the ropes course, Ellen is worried because she sees Ruthie, superwoman, having trouble crossing the polecat. The guys finish and go on to the tight rope. Colin is nervous about his ankle, but they finish and head to the final leg. As the ladies are just finishing the tight rope, Jamie, Mark and Colin take the zip line and head to the finish line for the win. The ladies finish soon after and are not sad because they know they fought the good fight. Mark gives them credit because they were great competitors throughout the whole time. The only regret Colin has is that Ruthie couldn't win as well. Johnny Mosley then surprises the guys and tells them they also each win a Saturn ion. Both teams are sad their journey is over. As Ruthie explains, The Battle of the Sexes may have been won by the men this time but the truth is that no matter who wins, this battle was about respect.
