You've got to guess four five-letter words. Replace the gray letter with another pre-selected unknown letter. Try to make a new word by shuffling the letters.

A new word has to be from the list of selection of words. You can find those words by cliking button. If your guess is wrong, there are small circles with letters:

• The grey letter is not in the word in any spot.
• The yellow letter is in the word but in the wrong spot.
• The green letter is in the word and in the correct spot.

If you find the right word continue guessing.

The final word can help you with the last word you need to guess. In the above example, we can conclude that in addition to the green letters [E, E, R and S], either the letter T or B will also appear.
