In general, the first rule in such a situation is: Don't tap anything! Often there are simply data collectors lurking behind such winning messages who want to make money with your personal details.

But where do pop-ups come from? They often come from large advertising networks that follow Internet users by analyzing the sites they browse and send them advertisements similar to products and services they are interested in. Casino operators usually can't do anything about it. The most you can do is ask your Internet provider to block ads; the eternal game of cat and mouse.

The fact that similar advertisements appear again and again is often due to cookies that are stored in the browser. Another possibility is that installed apps trigger such advertising messages.

And how do you get rid of aggressive advertising or prevent it from appearing again quickly? The following steps usually help:

Clear Cache on Android Smartphones/Tablets

1. Open the smartphone settings.
2. Tap the “Applications” menu item (on some devices it is also called “Application Manager”, “Apps” or similar).
3. Find and tap the browser app (often called “Internet” if you don’t have a browser like Chrome, Firefox, Opera or similar installed).
4. In the “Storage” section, tap “Clear cache”.
5. Delete the cookies in the settings of the browser app (usually found in the app settings under “Data protection”, “Delete personal data” or similar). If possible, set the browser so that it does not accept third-party cookies and the cookies are deleted every time you exit.

Since such ads can also be triggered by apps, try uninstalling recently installed apps if cleaning the browser does not solve the problem. In a guide, Google explains how you can identify problematic Android apps.

Clear Cache on iPhones/iPads

1. Activate airplane mode.
2. Open “Settings”, scroll to “Safari” and tap.
3. Tap “Clear history and website data”.
4. Close Safari window and restart device.
5. Deactivate airplane mode.
6. If you use other browser apps, repeat steps 1-5 with them too.

More Protection Options from Casino Pop-ups

If you want, you can install an ad blocker. This can prevent casino pop-ups from being displayed. If possible, apps should only be installed from the official stores (Google Play Store, Apple App Store). Look out for reviews from others there. If there are no or hardly any downloads, it is better to wait before installing. While Apple does not allow installation from other sources at all, a block can be set on Google's Android. If you're still using Android 9 or older, tap “Device Security” (or similar) in “Settings.” “Unknown sources” must not be ticked or the slider must be set to “off”.

With Android 10 the procedure has changed. There is no longer a central option to prohibit installations from unknown sources. Instead, you specify in the settings under “Security” and there in “Install unknown apps” which apps that are already installed on your device can be used to install new apps. For protection, it should be banned from all applications except the Play Store.
