The Coffins Symbolize the Final Gift to the Contestants
The number of contestants that die on the show is astronomical, and sooner or later, the players wind up in a black coffin shaped like a gift box with a pink ribbon. This idea was meant to symbolize how the creator of the game saw himself as God and was disposing of their remains in the incinerator as a gift or an act of mercy. But the coffin and pink ribbon added an extra level of cringe-worthiness to the series.
