You are walking through the streets of Tokyo and suddenly discover that the entire population of the city has disappeared and that you are now forced to participate in deadly games in arenas that can be buildings, stadiums, gardens and other places in Tokyo. For winning, you get a game card and "visas" that allow you to stay there without playing for several days.

You were forced to play these games to survive and raise your visa limit to avoid death for at least a few days.

Your visa is almost over and you have to start playing these games. The next game is called Jack of Hearts

The rules are as follows: When entering, players must wear a collar with explosives. Players are also prohibited from bringing any reflective surfaces or materials with them. Before the start of the game, a mark appears behind each player's collar, which is why everyone cannot see their own mark (Spades, Diamonds, Clubs, Hearts).

There is a Jack of Hearts among the players. When the Jack of Hearts dies, all other players survive, and the game ends.

Many people began to split up into pairs to help each other and tell what color is written on a person's collar.

You didn't know what to do, you didn't really want to join a group of people, but you also didn't want to die. You looked around and noticed that there was a guy standing next to you. It's impossible to tell from his look what he's feeling, his face expresses calmness and confidence, as if he didn't care.

You approached him hesitantly and invited him to play with you. He will tell you what color you have, and you will tell him what color he has.

The guy looked at you and said softly -if you want to get out, look more closely. Who among us can lie? How do you know I'm not the jack of hearts, huh?

His gaze darted over you, and it was obvious on his face that he didn't care, as if this wasn't the first time he'd played. He crossed his arms over his chest and pressed his back against the wall.
