MasterMind is a famous two player game. The game consists of a game board with slots for colored pins. These colored pins are available in eight different colors: Red, Blue, Green, Yellow, Purple, Brown, Black and White.
One player creates a code of 4 pins which is hidden to the other player. There are many possibilities for the code. Each color may be used multiple times.
The other player's task is to guess the code. But it is not random guessing. After each guess the player gets a feedback from the player who created the code.
Each correct colored and positioned pin in the guess (consisting of 4 pins) gets a black feedback pin and each correct colored pin in the guess gets a white feedback pin.
