Gem Driller

Drill deep. Strike it rich.

Drill into the wall, fill your hold with gems before the battery dies, then sell the haul or keep it to craft a better drill.

Gem Driller in development: a drill rig cutting through rock blocks studded with ore
Actual development screenshot. The game may change before release.

How to play

Hold to drill.

  1. Drill the wall

    Hold a finger on any exposed block to drill it. Deeper rock is tougher and holds richer gems; TNT, power cells and treasure chests are buried along the way.

  2. Sell or keep

    A run ends when the battery is empty or you surface. Sell the haul for cash, or keep the gems your next drill needs.

  3. Build a better drill

    Sharpen and harden the tip, upgrade the rig, and craft the next drill from the gems you dug up. Harder rock needs a harder tip.

What’s inside

Ten drills. Ten gems. One very deep hole.

A drill to work toward

Ten drills, from rusty to starstone, each crafted from what you mine. Every rock layer is a wall until your tip is hard enough to cut it.

Always something to chase

Missions, a daily gift, a Gem Book to complete, mining bots that earn while you are away, and a rebirth that makes every later run richer.

Progress on your phone

Your drill, upgrades, gems and cash are saved on your device. There is no account and no sign-in.

The game is free with ads: optional rewarded ads for a doubled haul, a battery recharge, a turbo drill or free cash, and an occasional full-screen ad between runs. There are no purchases. Read the privacy notice for details.

How long should I test?

Please stay opted in for at least 14 consecutive days and play regularly during that time. Tell us about pacing, performance, controls and anything that interrupts the fun.

What happens to my email?

Google Groups handles the request. Group owners and managers can see your membership details to manage access; the member list is hidden from other testers. Joining is for test access, not a marketing subscription. You can leave the group at any time. Read about tester privacy.

Google Play says the game is unavailable?

Check that your group request was approved and that you are using the same Google account on both sites. Changes can take a few hours to reach Google Play. If it still fails, contact us below.
