Intro. You receive an elegant and mysterious invitation to an exclusive ball held in an ancient palace lit by candles. The letter doesn't explain much, just informs the time and a single rule: everyone must wear masks. When you arrive, you realize that the event is much stranger than you imagined. Elegant guests dance, chat and move around the room, but no one reveals their true identity. However, there is a secret that few know: the ball is not just a party. A secret group of extremely rich and influential people organizes these balls every year. They watch everything hidden in private rooms in the palace, watching each guest as if they were pieces in a game. During the night, challenges, riddles and dangerous situations occur among the guests. Meanwhile, the organizers bet among themselves on who will win, who will reveal secrets... and who won't be able to leave the ball. At midnight, the true purpose of the ball will be revealed.
