A Third Adventure on Mystery Island
If you’ve been following along, “Mystery Island: Play For Keeps” is the next chapter in a series that seems to just get better with each film. The journey started with “Mystery Island” in September 2023, and picked up steam with “Mystery Island: Winner Takes All” in March 2025.

The good news? This series isn’t slowing down anytime soon. Fans can look forward to “Mystery Island: House Rules,” airing Sunday, September 14, 2025. While it’s not clear if the story will continue beyond that, it seems like the upcoming film promises more twists, clever mysteries, and the Henstridge-Weber dynamic that has made the series such a fan favorite. If you’re already hooked on the suspense and fun, it seems like September is shaping up to be another perfect Hallmark mystery night.
