In the “Letters” application, you should recognize which word can be made up of mixed letters and then put them in the correct order. The user can choose between two modes: in one of them the hint to the they are looking for is a picture, in the other the hint is a short verbal description of the lost password which is displayed after pressing the question mark. By clicking on two letters in turn, you can swap them. An additional difficulty is the limited time which is displayed in the upper right corner of the board.
