A group of desperate people who are desperate for money receive a mysterious invitation, inviting them to join a game together.
In order to win a prize of 45.6 billion won, 456 contestants with different backgrounds were locked up in secret places to play games.
Each round of the game is a traditional game that Koreans would play when they were young, such as one, two or three wooden people, but the consequence of failing to pass the level is death.

Who will be the final winner and what is the purpose of this game?
