I've just released my little app, Crossword Rush, to the Play Store. The puzzles are hand-made (not computer generated) with funny themes. The app is free and comes with 125 crosswords. I went with Kiip rewards rather than pop-up ads, and it is far less annoying. Check out the app here:https://play.google.com/store/apps/deta ... mdhbWUiXQ.
