Word Mastermind

Word Mastermind is a word game based on the traditional Mastermind game. Word Mastermind will select a random word for you to try to guess. With each guess the game will indicate which letters are in the word and which of those letters are in the correct location.

Play the Game

Use your computer keyboard or click the alphabet buttons to enter the letters of your guess. The letters will appear in the first available row of boxes. Use the backspace key on your keyboard or click the left arrow button to delete the last letter you typed. Once you enter the last letter of a row, the Enter button will be shown. You may then press the Enter key on your computer keyboard or click the Enter button to submit your guess.

If the word you entered is accepted, the letters in your guess that are in the correct location will turn green and those that are in the word but in the wrong location will turn yellow. Letters in the alphabet buttons that are not in the word will turn gray, and those that are in the word will turn green.
