Mastermind

Mastermind is a game of code breaking. You have 12 turns to guess the secret code. The code is composed of any combination of 4 colored balls from a pool of 6 different color balls, with repetition of the same color allowed. Example code:

blue ball
blue ball
blue ball
blue ball

After each guess, you will receive between 0 and 4 feedback pegs based on your guess. The pegs can either be red or white in color. A red peg signifies one of the balls you guessed was in the correct spot and of the correct color. A white peg signifies one of the balls you guessed was in an incorrect spot but of the correct color. Example guess and feedback based on above code:

blue_ball
green_ball
red_ball
purple_ball

Alternatively, you can choose to be codemaster. You will select your own code and watch the AI solve it (nearly instantly!), with each of the AI guesses and feedback displayed.
