Frequently asked questions

How do the numbers work?

A number shows how many hazards are in the eight tiles around it, including diagonals. A blank floor tile has no hazards next to it and opens up its neighbours automatically. Near a magnetic anomaly the numbers are distorted, and the in-game Field Guide explains how to correct for it.

How do I flag a hazard?

Press and hold a rock, or tap the button in the bottom-left corner to switch to Flag mode. Then tap any rock to flag it. Tap the button again to go back to digging.

Is every level really solvable without guessing?

Yes. Every cave is checked by a solver before you see it, and caves that would need a guess are thrown away. If you're stuck, look for a number whose hazards are all accounted for, or two neighbouring numbers that share tiles.

How do stars work?

You earn one star for extracting with every mineral, two if you also didn't lose a life or use a continue, and three if you also uncovered every safe tile in the cave.

I've run out of lives. What now?

Lives come back on their own, one every 20 minutes, up to five. You can also refill them with gems or by watching an optional ad. Winning a cave gives back the life you spent to enter it.

I bought something but didn't get it.

First, make sure you're signed in to the same Google Play or Apple account you used to buy it, then restart the game. Unfinished purchases are delivered when the game starts. For Remove Ads and the Starter Pack, open Settings and tap Restore Purchases. If it still hasn't arrived, email us with your order number from your Google Play or App Store receipt.

How do I get a refund?

Purchases are handled by Google Play and the App Store, so refunds follow their policies. On Android, go to Google Play order history. On iOS, go to reportaproblem.apple.com.

Will I lose my progress if I change phones or reinstall?

Your progress is saved on your device, so uninstalling the game or clearing its data will erase it. We don't offer cloud save yet. Remove Ads and the Starter Pack are linked to your store account and can be restored on a new device with Restore Purchases.

How do I change my ad privacy choices?

If you're in a region where we're required to ask for consent, such as the EEA or UK, open Settings and tap Privacy Options to change your choice at any time. You can also reset your advertising ID or turn off ad personalization in your device settings. See our privacy policy for details.

Can I get rid of ads?

Yes. The one-time Remove Ads purchase in the Shop removes the ads that play between levels. Optional rewarded ads, which you choose to watch for extra lives or coins, stay available.
