Sub Zero (television)

Sub Zero is an interactive children's game show based around the show Crystal Maze. The show featured on CBBC on BBC2 from the 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.
