In masternmind you need to think analytically and decode the set of coloured pegs your opponent is using. In these games the PC is the codemaker while you are the codebreaker. Guess at the colours and the order they are set in, and using the hints as to the right positions and colours you can find out what the code is. Break the code before you run out of turn, otherwise you lose! Try some mind-boggling masternmind games here!
