If you have entered a word which contains the letters but not in the correct spot they will be added to the final light gray square on that row. Keyboard Green letter - no other words will use that letter and have been placed correctly. Yellow letter - that letter needs to be placed correctly. Gray letter - that letter has been entered and is not used in any words. White letter - hasn't been entered. Goal is to find all words on the square word in under 15 attempts!
