The 456 participants in the Squid Game all have debts. They enter the game knowing nothing, and the last survivor takes home the prize of 45.6 billion won.

All 456 participants wear teal tracksuits with their respective player numbers attached to the left chest and back.

Participants cannot leave the facility or change their clothes until all games are finished.

First Game Red Light, Green Light (Eliminated if movement is detected by the giant doll robot within 5 minutes.)

Second Game Sugar Honeycombs (Pick out one of four shapes—circle, triangle, star, or umbrella—within 10 minutes. Eliminated if it breaks or if you fail to finish.)

Special Game Thinning Out (When the lights go out at bedtime, participants kill each other with iron pipes or weapons. The fight starts when Jang Deok-su's gang begins killing others. Survive them. In reality, the participants don't even know there is a special game. They just die in their sleep.)

Third Game Tug of War (Remaining participants form teams of 10 for a tug of war 30m in the air. You must pull the opposing team off the platform. The winning team passes.)

Fourth Game Marbles (Played in pairs; take the other's marbles to collect a total of 20. Eliminated if you lose all your marbles.)

Fifth Game Glass Stepping Stones (Choose the tempered glass over normal glass in a two-path bridge to reach the other side. Choosing normal glass results in falling and elimination.)

Sixth Game Squid Game (Offense and defense teams compete within the squid shape on the ground. The offense starts at the head, passes through the body, and returns to the head to step on the home square. The defense must stop them.)
