The players have their memory tested in a game in which they try to crack a safe. The players receive a secret telegram that contains a vital, secret and unpicked-up-on clue. A secret game tests the moral integrity of the players and they are then separated into "dumb" and "smart" groups as brainteasers test whether the players in this edition are worthy of the "MENSA" tag the show has earned. One player's rule-breaking actions lead to a fine being levied on the entire group.
