Crack the secret code using peg feedback in as few guesses as you can.

How to use it

  1. Click 4 colors from the palette to build your guess for the hidden code, then hit Submit Guess.
  2. A black peg means a color is the right color in the right spot; a white peg means it's the right color in the wrong spot.
  3. Use the feedback to deduce the code within 10 guesses. Clear Row lets you restart the current guess before submitting.
