In order to be a contestant, members of the public first needed to buy a TV Dreams scratchcard from their local National Lottery retailer, which was launched in February 1998.
The scratchcard winners would be referred to on the show as 'punters' and would watch the gameplay from a special seating area in the studio.
Each team is strapped into a giant Scalextric style racing car wired down by a bungee catapult.
There are three levels in all and once a team makes it to the top, they must then slide down an escape chute and sprint towards their podium to finish.
From the final remaining pair of punters, a wheel on a gigantic safe door is spun and whichever players space the pointer lands on goes forward to play the final round whilst the other punter is given the consolation prize of £5,000 and a bottle of champagne.
The episodes on 27 June and 4 July were broadcast in an earlier timeslot due to the BBC's coverage of the 1998 FIFA World Cup, which resulted in the National Lottery draw not actually happening within these episodes as tickets were still being sold by retailers at the time of broadcast.
