I just purchased Word Scramble Vol. 1.  You don't have to type the answer which makes it easy to play the game.  You just think what the word is in your mind or write it on paper then go to the next page (just like when you turn a page) and the answer appears. Then just keep on going.  For $1.50 it's worth the price.  When you upload it it states that there are 500 words, so I don't understand why the ad states 600.  The game says you start with 5 letter words and then work up to longer words. HOWEVER, it starts with 4 letter words -- perhaps for practice.  Anyway, I'm going to go ahead and get the Vol. 2 since it's only $1.50 and it's really the easiest playing game since you don't have to type anything.
