"Background play" in the context of a casino typically refers to a feature that allows you to continue playing casino games while the app or website is running in the background on your device. This feature is common in many online casino platforms and mobile apps. Here's how it works:

1. Mobile Apps: If you're using a mobile casino app, you can often enable background play by simply minimizing the app or switching to another app on your device. The casino game will continue running in the background, allowing you to receive notifications or alerts for wins or bonus rounds.

2. Web Browsers: When playing casino games in a web browser on your computer or mobile device, most modern browsers support background play. You can switch to other browser tabs or even use other applications while the casino game runs in the background.

3. Settings and Permissions: Some casino apps or websites may require specific settings or permissions to enable background play. Make sure you've allowed the app or site to run in the background in your device's settings.

4. Internet Connection: Ensure you have a stable internet connection, as background play relies on maintaining a connection to the casino server.

5. Battery Considerations: Be mindful of your device's battery life when using background play for extended periods. Running graphic-intensive casino games in the background can drain your battery faster.

It's important to note that not all casino games may support background play, and it might vary from one platform to another. Additionally, always gamble responsibly and be aware of your surroundings when playing in the background to ensure that you're in a safe and secure environment.
