During game play, players use this screen to enter code guess and analyze the clues given by the computer. Here you can see that players press single-letter keys on their keyboard to enter the codes. The computer responds with white and black 'pegs.' A black peg indicates one of the guessed colors is the right color and in the right position. A white peg indicates a correct color that is in the wrong position. The white and black pegs do not signify the color guesses from left to right.
