Mastermind-secret code is a mind and intelligence game played by 2 people. Players are divided into two: those who solve the password and those who set the password. The cipher puts 4 pawns in the game box so that the opponent cannot see them. In this game, one of the players makes a formation in a way that the opponent cannot see, and the opponent's aim is to guess his opponent's formation as quickly as possible. The player who breaks the opponent's codes the fastest wins the game. The goal of the game is to break the opponent's secret color code. There are 128 color pawns in 8 different colors in the game. There are 48 small pawns in yellow and red colors. The decoding player tries to break the opponent's code using color pawns. The deciphering player places the color pawns in the large circles in the game mechanism, one by one. The player who puts the password responds by placing small pawns in the small circles on the game mechanism. In this way, the player who breaks the opponent's code the fastest wins the game. After arranging, the person trying to decipher the code colors 4 guesses on the game table. Afterwards, the cipher puts a small red pawn of the correct color for the spot he placed in the wrong spot, but a small white pawn for the wrong position. It is perfect for parents who want to spend quality time with their children.
