Spellfie is the new interactive game show that will cast its spell on viewers, one letter at a time. In each episode four contestants give their brains a workout by trying to complete mesmerising word chains. But there’s a twist - every new answer is the same as the previous one, except for one letter. Easy, fun and so addictive. And sometimes harder than you think. An accompanying mobile app means viewers can play along at home, challenge their friends, or qualify for the TV show.
