Welcome to Mastermind.

You will need to guess a random code.

For each guess, you will receive a hint.

In this hint, X denotes a correct letter, and O a letter in the original string but in a different position.

Select a number of possible letters for the code (2-20): 4

Select a length for the code (4-10): 4

Enter a guess of length 4 (ABCD): abcd

------------------------------------

1: A B C D => X X O O

------------------------------------

Enter a guess of length 4 (ABCD): abcc

------------------------------------

1: A B C D => X X O O

------------------------------------

2: A B C C => X X O X

------------------------------------

Enter a guess of length 4 (ABCD): abdc

Your guess ABDC was correct!
