About this season
Britain's ultimate puzzler. At the start of each episode, six super smart strangers are split into two teams of three. The two teams try to accrue the most points through their powers of puzzling deduction. Every area of our player's mind will be tested across five puzzling rounds – In Other Words (language), Pressure Points (calculation), Rule Breakers (lateral thinking), Picture This (visual intelligence) and Memory Bank (memory). Then, in a dramatic plot twist, the winning team turn on each other to be named the ‘Best of the Best' and earn a place in the series Grand Final where the ultimate puzzler will be crowned.
