In the final eponymous Squid game, Gi-hun defeats Sang-woo after a brutal fight but refuses to kill him; he begs Sang-Woo to stop the game using the third clause. Sang-woo instead stabs himself in the neck, and asks Gi-hun to take care of his mother before dying. Gi-hun is returned to Seoul with a bank card to access the prize money, but discovers his own mother has died. A year later, Gi-hun remains traumatized and has not touched his prize money. He receives an invitation card from his gganbu, and finds Oh Il-nam on his deathbed. Il-nam reveals he created the game to entertain bored ultra-rich people like himself. He chose games he played as a child, and participated in Gi-hun's group out of nostalgia. As they talk, Il-nam wagers with Gi-hun on whether an unconscious man lying on a street corner will be helped before midnight. The man is saved, and Il-nam dies shortly after. Gi-hun retrieves Sae-byeok's brother and has him looked after by Sang-woo's mother, also giving them a share of the prize money. As Gi-hun travels to the airport to reconnect with his daughter in Los Angeles, he sees the same game recruiter playing ddakji with another desperate player, but manages only to get that player's invitation card. He calls the card's number before boarding his plane, demanding to know who is running the games. He is curtly ordered to get on the plane, but he ends the call and returns to the airport terminal.
