Crack the hidden 4-color code in 10 guesses or fewer. Each color is used once.
A hidden code of 4 pegs is made from 6 colors. Each color is used once, in the code and in every guess.
Tap colors (or press 1–6) to fill the next open slot. Tap a filled peg to remove it. Backspace removes the last peg. Press Guess (or Enter).
After each guess: black = right color in the right spot, white = right color in the wrong spot. Feedback pegs are not in slot order.
