The second part of the Squid Game series continues with Seung's team winning a game of tug-of-war, but not without losses. The players are later informed that they will be playing a game with marbles, where the objective is to collect 20 marbles from their opponent without violence. Seung forms an alliance with the old man, who is struggling with Alzheimer's, and they work together to win the game.
Meanwhile, Hwang, a police officer, is secretly investigating the Squid Game and discovers that it has been running since 1999. He also learns that his brother had participated in the game in 2015 and had won. Hwang eventually discovers the location of the game and tries to escape, but is caught by the leader and killed.
The remaining players move on to the next game, which involves crossing a glass bridge. The bridge is made up of reinforced and regular glass, and the players must navigate through it without falling. Seung and Kang are among the players who make it through, but Ali is killed in the process.
The game continues, and the players are eventually reduced to just two: Seung and Sang. They engage in a final game, which involves a squid-shaped drawing that they must navigate through. Seung emerges victorious, but not before Sang tries to kill him.
After the game, Seung is awarded the prize money and returns home to find that his mother has died. He decides to use the money to take care of Kang's brother and Sang's mother, and to start a new life. However, he soon discovers that the old man who had been playing with him was actually the host of the game, and that he had been manipulating Seung all along.
The old man reveals that he created the Squid Game as a way to entertain himself and to find something that the rich would enjoy. Seung is horrified and decides to take revenge, but the old man dies before he can do so.
The series ends with Seung trying to move on with his life, but he is still haunted by the memories of the game. He receives a call from the game's organizers, who try to convince him to forget about the game and enjoy his prize money. However, Seung refuses and decides to take action against them. The series ends with a cliffhanger, as Seung gets off the plane and prepares to take on the game's organizers once again.
