Do you know your mind? It is a family game based on guessing as all participants in the game do not know what is on their cards until the contestant starts asking questions. These questions are answered yes, no, or only. The 200 cards in the game are of three types, either as the name of a person, place, or inanimate. Each person will hold 3 red chips, the contestant will hand one card when guessing what is on the playing card. The winning method is very easy, each player has to guess 3 cards, i.e. the number of chips he holds, and every time the player comes in, he can ask several questions until the time ends according to the hourglass. At the end of time and the player does not guess the card, he must wait for his turn again, and if the player wants to change the card he holds, he must in turn take another card.
