BM FineWords4.0

From the original 4x4 square, which contains real horizontal and vertical words, at the beginning of the game there is a square containing pairs of words that have changed a letter between them. To find the original words, drag the letter from the first word over the corresponding letter in the second word and they change their place. If the correct word is reached, it becomes green. You will get a hint containing the words that have mixed letters
