Hi! I understand your House of Fun window keeps flashing and you’re unable to get rid of it. Let me get a bit more info to provide the best help:

- Is this flashing happening when you try to open the app, or while you’re playing inside the app?
- Are you using the web version through your browser or the desktop app on Windows 10?
- Have you noticed if the flashing window is related to any pop-ups, ads, or error messages?
- Have you already tried any fixes, like clearing your browser cache or restarting your device?

Once I get those details, I can guide you through targeted steps to resolve this. Meanwhile, here are some quick initial checks we can try:

1. Clear browser cache and cookies: Sometimes cached data can cause display glitches, especially with WebKit-based browsers on Windows.

2. Disable browser extensions: Some add-ons can interfere with app behavior, causing flashing or freezing.

3. Make sure your Windows and graphics drivers are updated: Outdated display drivers may cause flashing windows.

4. Try running the app in a different browser or use the Windows app version: This can help isolate if it’s browser-specific.

If you can share what you’ve tried or noticed so far, that’d help me tailor the guidance better!
