Down Deep on a phone at 5,202 metres in the Inner Core: golden rock, the miner protected by a shield bubble, power-ups along the bottom.

Down Deep

Dig to the centre of the Earth, one tap at a time.

A one-finger mining game. Tap left or right to break the rock beneath you, dodge what sticks out, and stay ahead of the cave-in falling from above.

  • 13 layers from Soil to the Inner Core
  • Haptics and sound tuned for every rock
  • Ads only when you choose a reward

How we work

Few things. Finished properly.

  • Small on purpose

    One clear idea per game or app, built carefully and finished. We would rather ship one polished thing than three half-baked ones.

  • Data kept light

    We collect what an app needs to work and nothing more. Shift Vault has no account and no servers at all: your data stays on your phone.

  • Fair to play

    Every Down Deep run that counts towards the leaderboards is checked on our server, so the top of the table belongs to real players.
