Curdle

If you are old as me you will remember the brilliant "Mastermind" game from the 70's. It was basically Wordle with colours.   You had to guess a secret "code" of 4 colours (can be duplicated), and you got clues in the form of;

 a white peg = right colour but in the wrong place

a black peg = right colour in the right spot.
