 The contestants were also the studio audience who sat in raised seating in opposite sides of the studio, and watched the games take place between the teams whilst supporting the chosen contestants.The two schools competing were originally represented by the T-shirt colours orange and green before they changed to blue and yellow for the second series in 1998.The contestant numbers were randomly selected, each used once only, for both teams (occasionally one team only) and announced and displayed by a large-screened computer named 'Flynn'.
