I love this game BUT

There is no way to resign or quit a game if you get stuck. You can undo moves or restart the same game but thats it. Perhaps the games designers should take the time to design more puzzles at each level of difficulty.
The few times hints are shown, they are not helpful - inevitably using letters that are not available to play.
Nevertheless, I am hopelessly addicted to and love playing this game.
