This is a list of Gladiators UK events featured in the UK version of Gladiators. Original series events The following events appeared during the original eight-year run of the UK series of Gladiators. In total there were 24 televised events with the Eliminator being the only event to appear in every episode. The event line-up changed from series to series, with new events being added every series, however over the years some events were dropped for safety reasons, and some never made it onto screen. Atlaspheres First appearance: series 1, 1992 – heat 1 Last appearance: series 8, 1999 – "Battle of the Giants" The first event ever shown on Gladiators in 1992. The two contenders and two Gladiators were enclosed in large spherical cages that they had to propel from within. The contenders' task was to roll the spheres onto any of four scoring pods. When a pod was activated, a plume of smoke was emitted and the contender scored 3 points. They were given 60 seconds to score as many points as they could in this fashion, whilst the Gladiators had to block the contenders from scoring. It was crucial that the contenders get the atlasphere into the dead-centre of a pod in order to score. This round holds the record for most objections where video replays demonstrated the referees had made the correct decision. The event's signature tune was "We Will Rock You" by Queen. The event was sometimes modified for celebrity specials, in which either two Gladiators faced three contenders, or three Gladiators faced three contenders from a standing start. From series 7 onwards, 2 contenders faced 3 Gladiators Contenders were not allowed to score on the same pod twice unless they had already scored on another since the last visit. Gladiators were not allowed to double-team a contender and could only keep them confined for ten seconds. Catapult First appearance: series 7, 1998 – heat 4 Last appearance: series 7, 1998 – quarter final 3 Two contenders faced two Gladiators. Each competitor was attached to a bungee cord and on the whistle they began to bounce up and down.

Each game lasted 60 seconds. This event had heavy modification to its gameplay between its initial concept
