If you feel that your coin balance doesn’t match what it was the last time you played, it is important to first make sure you are playing in the correct account. You can review your Player ID by going into the “Settings” menu.
Additionally, since you can enjoy the game on any device that’s logged into your Facebook or Apple account (unless you're playing as a Guest), we suggest checking with anyone who has access to those devices. The login history on your Facebook account settings can also be checked to see if your account is logged in somewhere you didn’t realize.
At times, leaving the application open when the device is idle or in sleep mode may cause communication issues as well. It is our recommendation to fully close the application or web browser when the game is not in use. You may consult your device's help guide or user manual from the manufacturer for more information.
Lastly, it is also a good idea to always be aware of how much you are betting on each spin, since an unintended spin at a high bet can give the impression of an incorrect bankroll balance.
