Sub Zero (game show)

Sub Zero is an interactive children's game show based around the show "The Crystal Maze". The show featured on CBBC on BBC Two from 21 February 1999 to 11 March 2001. The show had teams of both girls (XX) and boys (XY) (Team names were named after chromosome patterns.) doing challenges and, like "The Crystal Maze" children's episodes, contained tasks for children of the pre-teen age group.
The programme was named by a CBBC website user, 12-year-old Edward Stevenson.
Several former contestants have ended up working in the media themselves, including TV presenter Lauren Jamison and Cambridge-based radio presenter, Matt Webb.
