While you can play the same account on multiple devices, we do not recommend doing so as it can cause discrepancies in your data. Our cloud save tool was created to let players transfer their game from one device to another and not to play simultaneously. Playing with the same account on more than one device can causes your Bake Off scores, team orders, coin values, and can result in a loss of progress!
However you can play on multiple devices, so long as the game on your devices are not associated to the same Facebook account, at any time!
