Mastermind is a version of the classic board game that challenges you to crack a code of colours chosen by the computer. After each guess at the code, the computer gives you clues as to what you got right or wrong. Requires Netscape 3+, Internet Explorer 4+
How to Play

  • Start the game by clicking on the start button above
  • The computer will choose a code consisting of four coloured balls in a certain order. Your job is to guess the code.
  • Once the game has loaded, you will see a flashing green cursor at the top left of the grid, and eight balls on the right of the screen.
  • Click on a ball to place it in the grid at the position of the green square.
  • To fix any mistakes, click on the ball you want to change, and the cursor will move to that position.
  • Once you have entered your four balls, the computer will give you some clues as to how well your guess matches the answer by giving you two numbers. The right hand column tells you how many of your balls are correct, and the left hand column tells you how many balls are the right colours but in the wrong order.
  • For example, if it says "2 1" that means that one of the balls is correct, and two are in the wrong place.
  • You get eight guesses to crack the code
