The mastermind is a puzzle game, where you have to find a color code.
Your goal is to guess the secret code.
The code is a sequence of colored pins, and on each round after you make a guess you will get hints which will help to improve your guess.
The hints are either white or black:
-White for the good color but at the bad position
-Black for the good color and at the good position
Warning /!\ Don't be fooled by the white and black hint pins sequence: they are not in order with your guess pins.
Free game and easy to play.
