Hi! I’d love to help you get your Yahtzee app running smoothly again. When you say it "goes completely down while playing," do you mean it crashes, freezes, or shuts off unexpectedly? Also, does this happen at any particular point in the game or randomly?

In the meantime, here are some initial steps you can try on your Android 10 device that often resolve these kinds of issues:

1. Restart your device – This clears temporary files and memory, which can help the app run better.

2. Clear the app cache:
- Open Settings on your Android device.
- Tap Apps & notifications (or just Apps).
- Find and select Yahtzee.
- Tap Storage & cache.
- Select Clear cache (do not clear data yet, as that may delete your app info or progress).

3. Update the app – Make sure you have the latest version from the Play Store, since developers often fix bugs in updates.

4. Check for system updates – Sometimes Android updates improve compatibility with apps.

If you have tried these or if the issue persists, we can move on to some deeper troubleshooting like clearing app data (which resets the app but may lose local settings) or checking if any other apps running in the background could be causing conflicts.

Let me know if you’ve done any of these steps or if you need help with them! Also, please share if the crash shows any error message. That way, I can tailor assistance more precisely.

Are you satisfied with this starting point?
