Faced with a locked safe full of cash, contestants must crack The Code by answering questions that will open the safe and win them the jackpot. The jackpot starts at £3,000 but each time a contestant fails - which could only take one wrong answer - they are eliminated immediately and the jackpot grows by £500.
Contestants also have a choice. Do they try to unlock the safe alone or do they work together? In theory, the more brains, the easier the task - but teaming up also means splitting the jackpot.
Along with the contestants, Matt will be joined by newcomer and quiz-expert Lesley-Anne Brewis to offer some all-important extra facts and bits of trivia.
