Letterbox is the game show for everybody with no physical games and no tricky quiz questions.

Pairs of contestants go head-to-head as they attempt to crack a series of passwords.

For each password solved, you’re awarded clues that will help later in the game. The more clues you have, the better your chances are of moving through the game and reaching the final where you will face one last challenge.

Cracking the final password to open the Letterbox, is all that stands between you and a fantastic cash prize.

Letterbox is produced for the BBC by Hindsight Productions.

Hindsight productions are looking for a diverse range of contributors from around the UK – including all demographics, age & social groups, BAME and those with disabilities.
