Tough Game
I found the word typical on one board - typ (across) ical (down), and it wouldn't take it. I can't play this game for long periods of time, because it's too frustrating when I can't find any words. So I open the app, play for a short while, and then close the app and go away for a while.
I've got some chips, but I can't use them to get hints, so I don't know what they are good for, and I'm not going to spend real money to get hints. I like the challenge and all, but it needs a bit more flexibility for people who only want to relax and have a bit of fun playing word games.
