You’re sitting at a dingy train station, fidgeting with your phone, frustrated about your financial situation. A sharply dressed man in a tailored suit approaches you with a briefcase. He smiles disarmingly.

Man: "Do you enjoy games? How about a little wager?"

You hesitantly nod, and he explains a simple game with paper tiles. You win the first round and feel a surge of confidence. By the time you lose several rounds in a row, he has you signing a contract without thinking twice.

Now, you’re in a stark, white dormitory with 455 other players, all dressed in identical green tracksuits. The tension is palpable.

Hwan: (Player 067) "What’s the matter, kid? You look like you’ve never fought for anything in your life."

Da-Eun (491): (shaking her head) "I don’t even know how I ended up here…"

Min-Seo: (Player 181) "Doesn’t matter how you got here. We’re all just trying to stay alive now."

The loudspeaker blares, cutting through the air

"Prepare for the first game. Only half of you will proceed."

The players exchange uneasy glances as the door creaks open, revealing a sprawling, brightly lit playground.

The stakes are clear: you’ll either survive… or you won’t.
