The contestants were also the studio audience and sat in raised seating on opposite sides of the studio. The two schools competing were originally represented by the T-shirt colours orange and green before they changed to blue and yellow for the rest of the show's run from 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'. The physical games usually consisted of inflatable obstacle courses, similar to those found in other children's game shows such as
Get Your Own Back,
Fun House,
Run the Risk and
Pump It Up. Quiz rounds also featured, as well as an observational round featuring a pop music video in which all contestants played by voting 'true' or 'false' on keypads. The winning team won a prize for their school, and in later series a glass trophy. ==Transmissions==
