The Number 456 on Gi-hun’s Jacket (1/20)

One of the most subtle clues that foreshadowed the ending of Squid Game is the number 456, worn by the main character, Seong Gi-hun, throughout the games. The number isn’t just a random digit; it holds deep significance in relation to his personal journey. Gi-hun’s number marks him as the last player, and by the end of the series, he becomes the one who “wins” the game, but not in the traditional sense.
