Synchronization of mobile and PC accounts is very important as it gives you an opportunity to have your in-game balance, progress and level synced and optimized.
To synchronize your accounts, please use your phone/tablet, open Old Vegas Slots, and then go to the settings icon in the upper right-hand corner of the app page. Under the "Profile" tab, there is a "Connect Facebook" button. Tap this icon to bring up your Facebook account.
Please note that you must be logged into Facebook first in order to connect. If you are not logged in, you will be prompted to log in at that time.
Once you type in your Facebook email and password, you will get a notice saying that you have already authorized Old Vegas Slots.
If the above steps do not help, please contact our support team by submitting a request in the bottom right corner of the screen. Our agents will be happy to be of assistance ;)
