The game concept is smart and it is addictive to play. But the dictionary is awfully limited, and if you are a lover of language like I am, you will find yourself frustrated to use up powers and construct long words of ten letters or more, only to discover that they are not recognized.
Also: before the update, I could gather powers by merit alone. Not anymore: now powers can be only gathered commercially. It would be nice to have both options simultaneously. Too many game apps are turning over-commercial and if I run out of powers, Ill probably uninstall this one and move on to another game. My all favorite remains Word Jong - you only pay once, and it has a very comprehensive dictionary.
