Master Mind

Code-Master(Computer) will create a sequence of balls with six different colors. Colors may be duplicate.
You have to guess the pattern, in both order and color, within fourteen turns. Each guess is made by placing a row of different color balls on the board by pressing colored switches below. Once placed, the Code-Master provides feedback by placing ticks and crosses next to the row with the guess. A black circle resultis placed for the guess which is correct in both color and position. A white circle result is placed for indicating the existence of a correct color ball placed in the wrong position.
