This round holds the record for most objections where video replays demonstrated the referees had made the correct decision.
This event had heavy modification to its gameplay between its initial concept and first outing, with the 1998 programme mentioning a volleyball-style net situated between contenders and Gladiators.
Contenders, one at a time, made their way across the arena whilst dodging tennis balls fired at high speed by a Gladiator.
Each of the stations self-destructed at ten-second intervals and their weapons were rendered unusable (a difference from the US version, named Assault, which did not have a limit).
If the contender was hit directly by a tennis ball (ricochets off the floor, station or weapon did not count), they were eliminated.
Armed with a pugil stick (often referred to as a giant cotton bud), they attempted to cause the other to fall from their platform within the 30-second time limit.
After this, contenders would climb a vertical cargo net up to a gantry, where they would take a zip line down to a crash mat on the arena floor.
Hang Tough returned in the Sky series with the same rules and scoring system, but now played above water rather than crash mats.
A variation on Duel (which is known as Joust in the US series) in which contender and Gladiator were sat on sky bikes that twisted, bucked and spun like a rocking rodeo.
A significant majority of games ended in a time limit draw and this event was quickly phased out, making very few appearances before being axed after the 1995 series.
Both participants were forbidden from climbing above the red orbs at the top of the sphere, although this was largely for safety reasons as this took them into the swinging mechanism.
In 1998, the rules were changed: the contender's objective was to hit 4 lit sectors in different positions around the pendulum, while still avoiding being caught by the Gladiator.
Pendulum was originally planned to debut in the Sheffield live 1995 shows, but had to be dropped as the safety net was too big to fit in the arena.
If a Gladiator deliberately moved a scoring basket or blocked the opening, the affected player would be awarded the lost points after the game.
The song used for the male Gladiators was "The Boys Are Back in Town" by Thin Lizzy and later "Let's Get Ready to Rhumble" by PJ & Duncan.
The course comprised a snake beam, wire bridge, hand ladder, two web traps, a high and low wall and a sprint finish.
The course was rearranged for series 4 onwards and the rules were tightened up with penalty points being introduced for stepping off the beam or missing rungs on the hand ladder.
The only new game for series 5 and first road-tested in the 1996 live shows, the contender and Gladiator were positioned on a circular platform in which a large red sumo ball hung from the ceiling.
During pre-production of the first BBC series, an adaptation of the event, named "Battlebridge", was listed in the show's official booklet but was ultimately dropped before filming.
If either competitor released the rope or fell off a platform, the sudden loss of tension would cause their opponent to fall unexpectedly.
They proceeded along all five poles until the end where a suspended silver ring awaited, the first to grab this won the event in a shower of sparks.
In the BBC revival, the Walls were reduced to 10 metres tall[4], and did not feature the ridges or overhangs of the originals; they were also used as projection screens outside of the event.
For the first part of the event, the contender, armed with a rugby ball, had to get past a Gladiator without being tackled, gaining 5 points if successful.
The reason for Cyclotron's removal from the events roster is unknown, although it is rumoured that it was due to technical problems and certain Gladiators commented on it being too difficult to play and very hard for the audience to follow.
When the event was first shown, several warnings were issued by the referee to both contenders and Gladiators for wrestling, not allowing the other to get up after being pushed down on the platform, and for holding onto the supporting wires.
A sort of reverse on the Swingshot event, Contenders and Gladiators were attached to harnesses and push buttons to be launched into the air, where contenders attempted to throw balls into a lower white basket (worth 1 point each) or upper yellow basket (worth 2 points).
Just like in the "Hit and Run" event, the Contenders must keep moving upon crossing the bridge, as stopping for too long leads to either a 2-point penalty or disqualification.
The signature theme for this event is "Jungle Boogie" by Kool & the Gang, the opening section of which plays if a contender is knocked off the bridge.
[7] Contender and gladiator are raised thirty feet off the arena floor on a criss-cross grid of one-metre wide walkways.
As evidenced in the first Semi Final, if a Gladiator sustains an injury during the event (Sabre in this instance), the contender is automatically awarded the full points.
