🎯 Goal

Guess the secret code — a sequence of colored pegs — in as few tries as possible.

🕹️ How to play

  • Select a color from the palette, then click a slot in the current row to place it.
  • Fill all slots in the row, then press Submit Guess.
  • Click a placed peg to remove it (before submitting).

🔍 Feedback

  • Black peg = right color in the right position.
  • White peg = right color but wrong position.
  • The order of feedback pegs doesn't correspond to specific code positions — you must deduce which pegs are correct!

💡 Hints

  • Use the Hint button (3 per game) to reveal one correct peg position.
  • Colors can repeat in the secret code!
