There has only been three in the history of the WWE. The flesh-tearing, oftentimes gory scenery of the Three Stages of Hell match is primarily the reason why the tally of matches is so low. WWE will bring back the match at the next pay-per-view, Payback.
This time, it will involve WWE champion John Cena and Ryback.
Ryback initially announced an Ambulance Match, one day after he rammed Cena through the LED board. The following week, Cena one-upped Ryback by reintroducing this match.
Neither of them have ever been in this match, so in that regard, it should be a level playing field. Conversely, one person who does know about this match is Triple H, as he has participated in all three of the Three Stages of Hell matches.
Here is the history of this intense match.
