Mastermind: free daily puzzle
Crack the secret color code in six guesses.
About Mastermind
Mastermind was invented in 1970 by Mordecai Meirowitz. The codemaker picks a secret color sequence; you guess and get feedback — black peg per exact match, white peg per correct color in the wrong position.
Tips
- Open with two distinct pairs (e.g. AABB) to pin the palette quickly.
- Deduce color counts before worrying about position.
- Track which colors have been fully ruled out to narrow the search.
