I've never played the game, so I don't get it.
You start with any 5 letter word of your choice.
Any grey letter is wrong, any yellow letters are right but in wrong spot and any green letter is right and in right spot.
You get 6 chances to guess the word.
So I managed to get all but one letter with first guess (which alone is ridiculously lucky. Nearing lottery chances) and fail to get the last letter with additional 5 guesses.
