When does The Crystal Maze return?

The Crystal Maze originally consisted of six series, including five Christmas specials involving teams of children, which aired between 15 February 1990 to 10 August 1995. The first four series and three specials were hosted by Richard O'Brien, with the remaining two series and specials hosted by Edward Tudor-Pole.
