FAQ
Frequently asked questions
Where can I download Diamond Miner?
Diamond Miner is distributed only on Google Play. The Download page links to the official listing as soon as it is public on Google Play. Please do not install copies from anywhere else.
Which devices are supported?
Android phones running Android 8.0 or newer.
Do I need an account or an internet connection?
No. The main game works offline without an account. An internet connection is only needed to create or use an optional account.
Where is my progress saved? Will I lose it?
When you are signed in, your progress is saved online with your account, so uninstalling the game or changing phones does not lose it: just sign in again. If you play without an account, progress is not saved. The first time you sign in on a phone with an older saved game, that save is moved into your account once (with fair limits).
Do my machines keep mining when the game is closed?
No. Machines, the Drone Bay and outpost construction only progress while the game is open on your screen. There are no offline earnings.
I did not receive my verification or password reset email.
Check your spam or junk folder and make sure you typed the address correctly. If it still has not arrived after a few minutes, email us from the same address.
Can I earn real money or buy diamonds?
No. Diamonds are virtual game items, not money. They cannot be bought, sold, transferred or cashed out, and the game has no in-app purchases. Signed-in players may request a third-party reward code with diamonds when one is in stock (see Rewards). See the Terms and Conditions.
Why did my diamonds stop going up today?
Each account can earn up to 20,000 diamonds per day from all sources together (taps, machines, mini-games, daily reward, missions, achievements and referral rewards). The Home screen shows how much of today's limit you have used. It resets at 00:00 UTC (05:30 in India). You can keep playing; spending is never limited.
How do I request a reward code?
Open Rewards → Redeem Center while signed in. You need a verified email and an account at least 7 days old, and you can have one request open at a time. The rate is 10,000 diamonds per ₹1 of reward value (for example 300,000 diamonds for ₹30). A reward can be requested only while it is in stock. Every request is checked by a person; if it is refused, the diamonds come back to your balance.
How do invites and referral rewards work?
Your invite code is under Social → Invite Friends. While the programme is switched on, you earn 30,000 diamonds once for each friend who joins with your code, verifies their email, keeps the account for 24 hours and reaches game level 10. Referral diamonds count towards your daily earning limit, so they are added while you play over the following days. Details: Invites.
Does the game show ads or track me?
No. There is no advertising, no ad tracking and no analytics. Our Privacy Policy explains exactly what data is used.
How do I delete my account?
In the app go to Profile → Delete account. If you cannot sign in, follow the steps on the Account Deletion page.
Is Diamond Miner connected to any other game?
No. Diamond Miner is an independent game and is not affiliated with, endorsed by or sponsored by any other game or publisher.
