🎯 Mastermind

How to play Mastermind

1. The computer picks a secret code: 4 colored pegs, drawn from 6 colors. Repeats are allowed.
2. You make a guess by tapping colors from the picker at the bottom. Click a peg in your current guess to remove it.
3. After you submit, you get clues in the small box on the right of that row:
   • a filled circle = right color in the right place
   • a hollow circle = right color, wrong place
   The clues don't tell you which peg is right — just how many of each kind.
4. You get 10 guesses. Crack the code to win.

Each color also has a unique shape (●▲★■◆✚) so you can tell them apart even if the colors look similar. Prefer numbers? Tap the Markers button at the top to switch the pegs to 1–6.
