How can we help?

Tap a tube to lift the top layer of sand, then tap another tube to pour it in. A layer only lands on the same color, or in an empty tube. Fill every tube with one color to win the level.

Yes. Undo is always free and has no limit. One wrong pour never ruins a level.

Use a Hint to see a good next move, or add an extra tube to make room. Both are helpers you collect or buy with gems. You can also Undo as far back as you like, or restart the level from Settings.

No. There are no timers and no lives. Take as long as you like.

These are the chapter twists. Each one is explained in two short lines the first time you meet it: fog hides gems until they reach the top of a tube, ice locks a gem until another is poured onto it, vines lock a tube until a color is completed, a heavy gem is poured alone, a funnel tube only takes gems until it is full, and a gate tube accepts only the color on its ring.

Yes. Open Settings and switch on Color assist. Every layer of sand then gets its own symbol, so you can tell colors apart without relying on color alone.

Open the game each day to collect your reward. Seven cards make a streak, and day seven holds a treasure chest. If you miss a day, your streak moves back by one card. Dates follow the clock on your iPhone.

A collection of 60 named jewels. You find a new jewel every five levels, and nothing about it is random or for sale. Open the Jewels tab on the home screen to see them.

A monthly track of rewards that you climb by winning levels. The free track is always open. The gold track is an optional purchase for that month and is not a subscription: it does not renew by itself.

Yes. Levels work offline. Ads, purchases and Restore purchases need an internet connection.

Write to support@luminastudio.ai and tell us what happened. Please include the Player ID shown at the bottom of Settings, your iPhone model, your iOS version and the level number. A screenshot helps. The Player ID is a random number that lives only on your phone, so it is the way we can tell reports apart.

Open Settings and tap Restore purchases. You can also find it at the bottom of the Shop. Use the same Apple ID you bought with. Remove ads and other one-time purchases are restored this way.

Still missing? Check that you are online and signed in to the App Store, then try again. If it does not work, email us with the date of the purchase.

It removes the full-screen ads between levels. Optional reward videos stay available. It is a one-time purchase, and you can find it in the Shop and in Settings.

Gems and helpers live on your iPhone. If you delete the app or use Delete data, they are removed. Restore purchases brings back one-time purchases such as Remove ads, but not gems, helpers or a past Jewel Pass month that were already paid out. If you think something went wrong, email us and we will look into it.

Apple handles payments and refunds for App Store purchases, so we cannot refund them. Go to reportaproblem.apple.com and choose the purchase.

Yes. Progress is saved on your iPhone as you play. There is no account and no cloud copy. If you delete the app, your progress is erased. If you restore your iPhone from a backup, it may come back with the backup.

1. Open Settings.
2. Tap Delete data and confirm.

This removes the progress saved on this iPhone, including your settings. Purchases are not lost: use Restore purchases to get Remove ads back.

Gemlign is free to download and shows ads. Remove ads takes away the full-screen ads. To limit tracking for ads, use Settings, then Privacy in the game, and iOS Settings, then Privacy and Security, then Tracking. Ads are not personalised unless you allow it.

If an ad is inappropriate, misleading or broken, write to support@luminastudio.ai and tell us what you saw and roughly when. If you can, include a screenshot.

Write to support@luminastudio.ai and put "Privacy request" in the subject. The game has no account, so we cannot look you up by name or email. Everything the game stores is on your iPhone, where you can erase it yourself with Delete data.

The privacy policy explains what is stored, what is sent and your choices. The terms of use cover purchases and refunds.

Gemlign needs iOS 15 or later.

No. There is nothing to sign up for.

Gemlign is in English for now.
