If youre suffering from the bug where youre continually returned to your last game with three moves to go:
Finish the game, but once its solved dont tap to return to the game menu. Instead, press the iPhone button to return to the app menu and relaunch the app. You should be returned to the game menu where you can start a new game without a crash. (At least, I can.)
The game is still playable, but high scores remain inaccessible without causing a crash. The developers should be ashamed to have pushed out such a crippling update.
