Support and FAQ
Frequently asked questions are below. If you can't find your answer, write to us from the Contact page.
How do I play?
Guide the laser to the purple crystal. Turquoise ringed mirrors rotate when you tap them; purple-framed mirrors can be dragged to a new square. The diamond-shaped energy crystal wakes its linked source when it receives light. See How to Play for details.
Do I need an account or to pay?
No. LUNERON is free; there are no accounts, no ads and no real-money purchases. POP Coins are earned only by playing.
Where is my progress stored?
In this device's browser. It is never sent to a server. Come back with the same browser and you'll continue where you left off.
How do I change the language? Will I lose my progress?
On the website, use the language button in the top menu; in the game, use the globe icon at the top of the main menu or Settings → Language. Your choice is saved on this device. Changing the language never affects your levels, stars, POP Coins or chests.
Will my progress be deleted on iPhone?
Safari may delete local data for sites you haven't visited for a while (about 7 days). To prevent this, open the game in Safari and use Share → Add to Home Screen, then play from there; the Home Screen app isn't affected by this limit. We also recommend making a backup now and then with Settings → Move your save → Copy code and keeping it in Notes.
How do I move my progress to another device?
- On the old device, open the game: Settings → Move your save to another device / site.
- Choose Download backup file or Copy code.
- On the new device, choose Restore from file or Paste code.
- Check the comparison and tap Load backup.
Damaged or incompletely copied backups are never loaded; your current progress changes only if you confirm, and you can undo the last import with one tap.
Can I bring over progress from the earlier POP GRID version?
For browser security, each site can only see its own save, so progress from the earlier version played at another address won't appear here automatically. If that version has a "Move your save" option, take its backup code and load it here with Paste code. The save format is the same, so your levels, stars, POP Coins and chests transfer completely.
There's no sound
On iPhone, check the silent switch on the side and tap the screen once; browsers only turn sound on after the first tap. Make sure the sound button in the game is on.
Can I add the game to my home screen?
Yes. iPhone/iPad: Safari → Share → Add to Home Screen. Android: Chrome menu → Add to Home screen / Install app. Computer: the install icon in the Chrome or Edge address bar.
I'm stuck. Are there hints?
Yes. The hint button gives three levels of help, and the first is always free. Every hint is calculated from your current position towards the shortest solution.
Is it on the App Store or Google Play?
Not yet. We'll announce the mobile apps on the home page when they are released.
