Hi there! I understand that your Mahjong 3! game on your Kindle with Android OS 9 won't update or open. I'd be happy to help you get this sorted out.

To start, could you tell me if the game ever opens at all, or does it just stay stuck when you try? Also, have you tried updating it from the Amazon Appstore (since Kindle uses that) or Google Play Store? Any error messages you see when trying to update or open the game would be very helpful too.

In the meantime, here are some initial steps to try:

1. Restart your device: Sometimes a simple restart helps clear temporary issues.

2. Check your internet connection: A stable Wi-Fi or mobile data connection is necessary for updating and launching the game. You can try toggling airplane mode on and off or connecting to a different network.

3. Clear the app cache and data:
- Go to Settings > Apps (or Applications) > find Mahjong 3!
- Tap Storage
- Tap Clear Cache first. Then if needed, try Clear Data (this may reset game settings or progress, so do this as a last resort if you are okay with it).

4. Update the app manually:
- Open your Amazon Appstore or Google Play Store (whichever you use)
- Search for Mahjong 3!
- Tap Update if available.

5. Reinstall the app:
- Uninstall Mahjong 3!
- Restart your device
- Reinstall the game fresh from your app store.

Because your Kindle runs Android 9, ensuring compatibility might also be a factor. If none of these steps work, the issue might be more specific, and I'll guide you through advanced options or checking for known server issues.

Could you please let me know which steps you've tried already and any error details you see? That way, I can tailor my advice better for you.
