           The playing field is a number of slots, in which a number of
           colored pegs can be placed. I will start by placing a peg in
           each slot, and you will then have to guess what color peg I
           have in each slot. You will then place a peg in each slot,
           and I will have to guess what color peg is in each slot. You
           get one point for each guess I have to make, and I get one
           point for each guess you have to make.

           A guess consists of a possible sequence of colored pegs. The
           guesser's opponent then answers with two numbers: the number
           of pegs in the guess that exactly match the corresponding
           pegs in the configuration, and the number of pegs in the
           guess that match in color but not in position. For example,
           let's say we are playing with five slots, and the following
           situation occurs:

           my configuration:   red  red  yellow    blue brown
                 your guess:   blue red  green     red  red

           The two numbers would then be 1 and 2. The 1 is because we
           each have a red peg in the second slot. In addition, your
           blue matches my blue, though the position is wrong, and one
           of your reds matches my red in the first slot. Only two of
           your reds match because I only have two reds in my
           configuration.

           You will have a chance to decide before we start on how many
           slots and how many colors you want to use.

           When you enter a guess, type the names of the colors,
           separated by spaces. When I make a guess, answer me with two
           digits, possibly separated by spaces.

           Any time it is your turn to enter a guess, you can ask me
           what happened by typing "review" instead of your guess.
