When you encounter a message like this, it is typically because you have a game open on another device. We would suggest closing any games that might be open on other devices, as they are likely causing this issue. When you open a Casino game on our site, a new window will open for that game. Leaving this window open may cause issues when playing from other devices, even if they are logged out of their account on the other device. Make sure to close out games when you are done with them to prevent issues like this from happening.
