This is an excellent game which not only broadens your vocabulary, but also refreshes your spelling ability. So it would be the appropriate game to play if you have a child that is a spelling champion or is just beginning to read. The goal in this game is to feed Lex, the bookworm with new words, you do this by touching the first word on the screen and then move your finger to make a chain of letter forming a word, then these letters move to Lex where he eats them causing new letters to appear from the top of the screen, so a little strategic use of letters would be an excellent idea. The longer the words, the happier he becomes. But this is just a minor part of the game, you will also have to pay attention to the green tiles, gold tiles and platinum tiles to make extra points, and to fill the bar faster so you can earn a new rank as bookkeeper or proofreader or even encyclopedia salesman  and move up to the next level. But be aware of the burning tiles, they appear out of nowhere and can give you the headache of your life, so use them in a word quickly before they have the chance to burn their way down to the bottom of the screen and cause a fire in which your library will burn, which then leads to a game over. One other great feature of this game is that it has a vocabulary explanation for the rare words, and it also keeps track of your longest and rarest words. Besides, this game represents a good brain exercise, in which you learn new vocabulary, broaden your word fund and have the time of your life when spending time with the cute Lex and his letters.
