Beginner's guide

How to play Diamond Miner

New to the mine? This guide takes you from your very first tap to running a full-scale operation.

Start playing
Open Diamond Miner and you land on the home screen with your first rig ready. You can start without an account; sign in (Profile) to save your progress online automatically.
Collect diamonds
Tap the crystal core or the Tap to Extract button. Each tap adds your current tap power in diamonds. Every 100 diamonds you mine raises your level.
Upgrade your machines
Open Machines. Basic Miner adds tap power, Gold Miner mines every minute while the game is open, and Iron Miner and the higher tiers do both. New tiers unlock at levels 5, 10, 20 and 35.
Build your outpost
Open the Outpost and start a building. Upgrade the Command Center to raise the level cap for everything else. The Refinery and Drone Bay boost income; the Research Lab makes machines cheaper.
Play mini-games
Visit Games for Crystal Run, Crystal Tap, Gem Match and Memory Match. Finish a round to earn a diamond reward and try to beat your best score.
Keep your streak going
Under Rewards, claim your daily reward every day for a bigger bonus, complete missions and unlock achievements.

Crystal Run controls

Mastering the runner

Change lanes: tap the ◀ ▶ buttons or swipe left and right.
Shoot: hold FIRE to blast drones in your lane.
Avoid rocks: rock falls block your shots, so dodge them instead.
Grab crystals: they add to your score and reward.
Survive: each hit damages your hull. Upgrade the Armory for more hull and damage.

Pro tips

Early on, tap power pays off fastest. Once Gold Miner and the Drone Bay are running, your mine keeps working between taps.

A higher Research Lab level cuts the cost of every machine upgrade, up to 20% off. Build it before saving for the top tiers.

The daily reward grows through a seven-day streak. Open the game once a day to keep it going.

Machines and outpost buildings only work while the game is open on your screen. There are no offline earnings.
