Seong Gi-hun, a divorced father and gambling addict, is introduced as he struggles to make ends meet while living with his elderly mother. He is deeply in debt and is often seen at the racetrack, where he loses money. One day, he is approached by a mysterious man who offers him a chance to win money by playing a simple game. Gi-hun accepts the invitation and is taken to a secluded location where he meets other players, all of whom are in dire financial situations.

The players are soon informed that they will participate in a series of children's games, with the promise of a large cash prize for the winner. The first game is "Red Light, Green Light." As the game begins, players must move towards a finish line while a giant doll turns its head to catch anyone moving during "red light." Many players are eliminated when they fail to stop in time, and it is revealed that elimination means death. Gi-hun and a few others, including his childhood friend Cho Sang-woo and a North Korean defector named Kang Sae-byeok, manage to survive the first game.

After the first game, the surviving players are given the option to leave the game, and many choose to do so. Gi-hun returns to his life, but he is haunted by the events and the deaths he witnessed. He learns that the prize money is substantial, and he struggles with the moral implications of returning to the game. Eventually, he decides to rejoin the competition, motivated by the need to provide for his daughter and to escape his debts.

The second game is "Sugar Honeycombs," where players must carefully carve out shapes from a honeycomb candy without breaking it. Tensions rise as players work against the clock, and some resort to cheating. Gi-hun, with the help of Sae-byeok and a few others, manages to succeed, but not without witnessing more deaths. The psychological toll of the games begins to weigh heavily on the players, and alliances start to form.

In the third game, "Tug of War," teams are formed, and Gi-hun's team, which includes Sang-woo and Sae-byeok, must face off against a stronger team. They strategize and use their wits to win, showcasing their teamwork and ingenuity. The victory comes at a cost, as the losing team is brutally killed, further deepening the emotional scars of the survivors.

The fourth game is "Marbles," where players are paired off and must play a game of their choice to win each other's marbles. Gi-hun is paired with his elderly friend, Player 001, who has been a source of wisdom and support throughout the games. In a heartbreaking twist, Gi-hun ultimately has to betray Player 001 to survive, leading to a devastating emotional conflict within him.

As the games progress, the players learn more about the masked guards and the mysterious Front Man overseeing the competition. Gi-hun discovers that Sang-woo has been making ruthless decisions to ensure his own survival, including manipulating others and betraying alliances. The tension between the two friends escalates, revealing the darker sides of their personalities.

The final game is "Squid Game," a complex and brutal version of tag. Gi-hun faces off against Sang-woo, and the emotional stakes are at their highest. The two engage in a fierce battle, with Gi-hun ultimately gaining the upper hand. In a moment of compassion, Gi-hun offers Sang-woo a chance to leave the game alive, but Sang-woo chooses to take his own life instead, leaving Gi-hun as the sole survivor.

After winning the game, Gi-hun is awarded the massive cash prize but is left traumatized by the experience. He returns to the real world, but the weight of his actions and the loss of his friends haunt him. He learns that Player 001 was the mastermind behind the games, and this revelation adds another layer of complexity to his victory.

In the final scenes, Gi-hun attempts to reconnect with his daughter but struggles to reintegrate into society. He discovers that the games are still ongoing, as he witnesses a man being recruited to participate in the next round. In a moment of defiance, Gi-hun decides to confront the organizers of the games, vowing to put an end to the horrific cycle of violence and exploitation. The series ends with Gi-hun boarding a plane, determined to take action against the organization that put him and so many others through hell.

As the final episode unfolds, the tension is palpable. Seong Gi-hun, the last remaining contestant, stands in the arena, having survived the brutal games that claimed the lives of his friends and fellow players. The atmosphere is heavy with the weight of loss and betrayal. Gi-hun faces off against the final challenge, a twisted version of the childhood game "Squid Game," where he must outsmart his opponent, the enigmatic and ruthless Sang-woo.

In a heart-wrenching climax, Gi-hun manages to defeat Sang-woo, who, in a moment of desperation, asks Gi-hun to end his life, unable to bear the guilt of his actions.

However, Sang-woo takes his own life, leaving Gi-hun to grapple with the emotional aftermath of their friendship and the choices they made throughout the games.

With the games concluded, Gi-hun is declared the winner and is awarded a massive sum of money.
