The 456 participants in the Squid Game all have debts. They enter this game knowing nothing, and the last one to survive wins the 45.6 billion won prize.

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

Participants cannot leave this place or change their clothes until all games are finished.

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

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

Special Game Weeding Out (When the lights go out during sleep, participants kill each other with pipes or weapons. The fight starts when Jang Deok-su's gang begins killing others. You must survive them. In reality, the participants don't even know a special game exists; 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 edge. The winning team passes.)

Fourth Game Marbles (Played in pairs; you must take your partner's marbles to collect a total of 20 to pass. If you lose all your marbles, you are eliminated.)

Fifth Game Glass Bridge (Choose between tempered glass and normal glass on two paths to reach the other side. If you choose normal glass, you fall and are eliminated.)

Sixth Game Squid Game (Offensive and defensive teams compete on a squid shape drawn on the ground. The offensive team must start at the head, pass through the body, and return to the head to step on the home square. The defensive team must block them.)
