How to play Mastermind
A secret code of four pegs is chosen from six distinct shades. Pick shades to fill a guess row. After each guess you get feedback: a filled peg means a shade is correct and in the right spot; an open peg means a correct shade in the wrong spot. Use the clues to crack the code in ten tries.
