50/50 was a British children's game show that was broadcast on BBC1. It was broadcast from 7 April 1997 to 12 July 2005. Two schools in the UK put forward 50 students, each child given a number from 1–50 which they wear during the show, before each round a random number generator picks which students will take part in the next game.
The t-shirt colours were originally green and orange but this was changed to blue and yellow. They sit opposite each other in raised seating while the game takes place in between them. Most of the children will not get an opportunity to play in a game, but there are question rounds and observation rounds where points are won by the number of correct answers. The games usually consist of inflatable obstacle courses similar to those found in Get Your Own Back, Fun House and Run the Risk.
