Squid Game has featured a number of religious references throughout the nine episodes. There are a handful of scenes that features vivid references to Christianity.
Test and Reward
Squid Game features putting people through tests for a cash reward. This is subtle stance taken by the director to refer Christianity. The Bible says, "Behold, I am coming soon, bringing my recompense with me, to repay everyone for what he has done" (Revelation 22:12). This verse refers to the rewards which are to be given to whoever did good.
Resurrection
In episode 6 of the series, viewers get to witness the heartbreaking death of Player-1 (Oh Il-Nam). However, the last episode reveals that his death was staged and he has been alive throughout the series only to die in the last episode. This event in the series assimilates with the resurrection of Jesus.
​Sacrifice
Sacrifice is a significant observance in most religion including Christianity. Abraham was ready to sacrifice his son for God while Christ's sacrifice was an atonement for the sins of the entire humankind. In Squid Game, Ji- Yeong, an orphan sacrifices herself for Sae-Byeok after learning that Sae-Byeok's family needs her.
"Abel and Cain"
According to bible, the first murderer in history was Cain who killed his own brother Abel. In one of the late episodes of Squid Game, it is revealed that one of the protagonists, Hwang Jun-Ho and an antagonist, Hwang In-Ho are brothers. Upon unveiling the racket run by In-Ho, Jun-Ho is cornered and killed by him. This scene resembles the event of Abel and Cain from The Bible.
​
Bridge of Dread
One of the games in Squid Game involved crossing a bridge of glass. Stepping on the non-tempered glass would break it and cause death. In Western Christianity, a similar bridge is featured where all souls would cross the bridge but only the evil souls would fall off the bridge into hell.
