Opposite Worlds was an American reality game show that originally aired on the cable channel Syfy. The format of the show was based on the successful Chilean series Mundos Opuestos which aired from 2012 to 2013 on the national free-to-air channel Canal 13. The series revolved around a group of strangers divided into two teams, and made to live in a house divided by "future" and "past" themes. The teams competed in weekly challenges to determine where they would live. One contestant, known as the Decider, selected two contestants to compete in a challenge, with the loser being eliminated from the game. The winner of the series, determined after six weeks, won a $100,000 prize. The series was hosted by Luke Tipple. The show premiered on January 21, 2014 and aired on Tuesdays and Wednesdays, with the latter being a live elimination episode. The show was cancelled after one season.
