Secret Genius 1 сезон 3 серия — Episode 3

The next 12 contestants face a fresh set of challenges based on the games Mensa use to measure IQ, including a code-breaking challenge so complex that the youngest contestant, student Rosie, really struggles with - and not just because she may never have seen a landline phone before. By the end of the episode, only three will earn a coveted place in the Oxford finals.
