Hi there! I see your Solitaire app on your iPhone isn't opening. I’d love to help you get it working again. Just to clarify, when you say it won’t open, do you mean the app doesn’t launch at all, or does it open but get stuck on a loading screen? Also, have you noticed any error messages?

While I wait for your details, here’s a simple first step tailored for your iPhone with iOS 18.7:

1. Force close the app:
- Swipe up from the bottom of your screen (or double-click the Home button if you have one) to open the app switcher.
- Find the Solitaire app and swipe it up off the screen to close it completely.
- Then try reopening it.

If that doesn't help, next steps would be:

2. Restart your iPhone:
- Hold the side button and either volume button until you see the power off slider; slide to power down.
- After it turns off, press and hold the side button until the Apple logo appears.
- Then try the app again.

3. Check for app updates:
- Open the App Store, tap your profile icon on the top right, and scroll to see if there’s an update available for Solitaire.
- If yes, update it and then try launching the app.

4. Reinstall the app (this won’t delete your game progress if you’re signed into a cloud account):
- Tap and hold the Solitaire icon, tap “Remove App” then “Delete App.”
- Head to the App Store, search for Solitaire, and reinstall it.

If you’ve already tried these, or if the app briefly opens but crashes or gets stuck, please let me know so I can suggest more advanced fixes, like resetting app settings or checking for iOS system updates.

Does this help you get Solitaire running?
