The winner of Squid Game Season 3 is Kim Jun-hee’s newborn daughter , also known as player 222. Gi-hun sacrifices himself to protect the baby during the final game, leading to her becoming the last survivor and winner of the deadly competition.

Key context:

• The final game, called Sky Squid Game, involves players moving across three towers with deadly rules requiring at least one participant to be pushed off each tower.
• Gi-hun protects the baby throughout the game as other players, including the baby's father Myung-gi, try to kill her.
• Ultimately, Gi-hun and Myung-gi fight, resulting in Myung-gi's death. Gi-hun then throws himself off the tower, ensuring the baby is the sole survivor.
• The creator of Squid Game, Hwang Dong-hyuk, intended this ending to symbolize hope and the future generation, with the baby representing a chance at a better world.

This unexpected outcome differs from prior seasons where adult contestants won, emphasizing themes of sacrifice and humanity amid the brutal game.
