Letterbox, 6.30pm, BBC2

MEL GIEDROYC (pictured) presents this potentially addictive new weekday gameshow, in which pairs of contestants compete to win £2,500 by cracking a series of passwords. As they progress, winning letters en route, they get closer to the Letterbox, in which the prize is locked. Can they solve the final password and open the box?
