Mastermind

Mastermind is a code cracking game. The computer thinks of a code and the player must guess it. After each guess the player is informed of the number of correct digits in the correct position, and the number of correct digits in the wrong position. Using logic deduction the player tries to guess the code in as few guesses as possible.

The game features two difficulty levels. The lower difficulty only uses the numbers 1 through 6 while the more difficult variant uses the numbers 1 through 9.
