You can connect your account to Facebook in the SETTING of the game. Your first connection would bring you with plenty of coin rewards!
Use your old device to log into Facebook through the game. In this way, your level progress and Erudition will be synchronized to your Facebook account. Then log into Facebook through the game on your new device, and you will have your progress in a few seconds. In this way, you can play Crossword Quest on both your old and new devices.
Since coins, hints and no-ads are devices specific, they could not be transferred through devices. You can still use these items to help you pass levels on your old device. Thanks for your understanding!
