The games staff wear a distinctive uniform that helps establish their hierarchical role and anonymity. Their attire is characterized by a bright pink jumpsuit: This color contrasts sharply with the green of the participants, creating a clear visual distinction between guards and players. Masks with geometric symbols: Each staff member wears a mask that completely covers their face. These symbols indicate hierarchical rank within the staff: Circles are the lowest-ranking, followed by squares, and finally, triangles, which appear to be the highest-ranking supervisors.

In contrast to the guards' uniform, the players wear teal or light green tracksuits. These are tracksuit-style, with a jacket and sweatpants. They bear a white three-digit number on the back and left chest, identifying them individually.

The games take place on a remote island with a sophisticated, secret facility, carefully concealed and protected by a private army. The motive for this brutal massacre is to satisfy the sadistic desires of a wealthy and powerful elite who use the participants as pawns in a macabre game, where life and death are decided by chance and cruelty. The island serves as an isolated stage where the wealthy and powerful can observe without interference the struggle for survival of desperate individuals, finding pleasure in their suffering and in the absolute power they wield over the life and death of the participants. The massacre is a spectacle staged for their perverse entertainment, a ritual of violence and opulence that exposes the profound inequality and moral corruption of society.

The games are a series of six traditional Korean children's games, but with a deadly twist: defeat means death. Each game takes place in an elaborate and spectacular setting, with an aesthetic that contrasts with the brutality of the consequences. The rules are briefly explained before each game, but the ambiguity and time pressure contribute to the tension and chaos. Participants, recruited from among those with extreme financial difficulties, are forced to compete for a prize of 45.6 billion won.

The process begins with the participants being confined to a common space where they are provided with food and lodging but without precise information about their situation. As the games progress, tensions rise, and alliances are formed and broken with survival as the sole objective. Violence and betrayal are constant, and the lack of information and psychological pressure contribute to the dehumanization of the participants. The games are supervised by masked and heavily armed personnel who are responsible for carrying out death sentences and ordering them to be killed.
