Glad you found those, EmScape!
I just checked and the Amazon Appstore does not have Cool Reader. Please do post the links in the App section, especially if your Crossword app is a good one. You are not the only one who likes puzzle-type games.

(You might try them first to make sure they work as you want them to on the PE.)
While I was checking the Amazon store I "bought" the free app of the day, in this case a Sudoku app. I have one already, but maybe this one is better! hehe Never hurts to try, eh??
