The repeated letters handling is subtle. If your guess contains repeats of a letter it will highlight as many of them as there are repeats in the actual word. Any that can be green will be green and other repeats will be marked yellow to make up the numbers (going from left to right). Repeats left over after that are black. So for example if the target word is QUEEN and you guess EELER (not an accepted guess but let's pretend it is), it would be yellow, black, black, green, black.
