Hi there! I see you're having no sound issue with Magic Tiles 3 on your iPhone running iOS 18.7. Let's work through this together to get your sound back.

First, just to better understand, is there no sound at all when you open the app, or does the sound cut out during gameplay? Also, do you hear sounds from other apps or your phone in general?

Meanwhile, here are some quick steps to try for restoring sound in the game:

1. Check your device's mute switch: Sometimes the physical mute switch on the side of your iPhone can silence game sounds. Make sure it’s off.

2. Increase the volume: Use the volume buttons to make sure the sound isn’t turned down low.

3. Restart Magic Tiles 3 app: Swipe up from the bottom to see your app switcher, then swipe the Magic Tiles 3 app off the screen to close it. Reopen it to see if sound returns.

4. Restart your iPhone: A simple restart can refresh audio settings sometimes.

5. Check in-app sound settings: Open Magic Tiles 3, go to the settings menu inside the game, and verify that sound/music options are turned on.

6. Update the app: Go to the App Store and check if there’s an update available for Magic Tiles 3. Developers often fix sound bugs in updates.

7. Reinstall the app: If none of the above helps, consider uninstalling Magic Tiles 3 and reinstalling it. Just make sure your game progress is backed up through your account.

If after these steps the problem persists, sometimes audio glitches in Magic Tiles 3 can be caused by recent bugs, and the developers release patches to fix them quickly. Let me know if you want me to check if there’s a recent known issue or fix.

Does this sound like a plan? And did you attempt any of these steps already? That way, I can tailor the next suggestions better.
