The show itself was set in a fictional skyscraper (which was depicted in the titles by a London council tower block, Trellick Tower, in North Kensington) with a talking lift.

In the first series, the lift was played by David Walliams, who later starred in Little Britain.

The aim of the show was to complete each game (set on a "floor" of the skyscraper), gradually rising up the tower.

The first game was where giant letters had to be fished out of a swimming pool (ostensibly a soup bowl) to make words on the "fridge".

The catch was that the "dark knight" was attempting to stop them, though he could only see the player's last move which was lit up.
