🎯 Mastermind Digits
Crack a hidden 4-digit code using black-and-white peg feedback after every guess.
How to Play Mastermind Digits
Goal: figure out the secret 4-digit code (digits 0-5, repeats allowed) in 10 guesses or fewer.
Controls: click digits to build your guess, then click Submit Guess. A filled dot means a digit is correct and in the right spot; a hollow dot means it's in the code but the wrong spot.
Tips:
- Your first guess is pure information-gathering — try 4 different digits to learn the most from the feedback.
- Track which digits you've confirmed are in the code at all, separately from which positions you've confirmed.
