The Elimination Chamber match debuted over 11 years ago at the 2002 Survivor Series and this Sunday's (Feb 23) self-titled pay-per-view will see the 17th edition of the grueling six man elimination which takes place inside a circular steel, chain linked structure. For those unfamiliar with the rules; Two men start in the ring, whilst the other four participants begin in pods in each corner of the chamber. Every 5 minutes, a new combatant randomly enters. Superstars can be eliminated at any point once they have entered the match, but only by pinfall or submissions, as there are no disqualifications or countouts. The matches usually take place for a major title or for a world title shot at WrestleMania. The WWE, World Heavyweight and ECW titles have all been on the inside the chamber. This Sunday's Chamber match is for Randy Orton's WWE World Heavyweight Championship, with the other participants being John Cena, Daniel Bryan, Sheamus, Christian and Cesaro. Orton will be hoping it's 7th time lucky in the Chamber, having not ever won one before. Overall, 45 superstars have taken part in at least one Chamber match over the years, but here we'll go through the top 10 most successful competitors, in terms of victories and eliminations.
