Sell your discoveries to buy upgrades from your profits and dig even deeper down a huge mine. Be careful not to get stuck down the mine, fall down chasms or be crushed by rockfalls!

- randomly generated mines (every game is different!)
- buy lifts, improved mining gear, supports, ladders, torches and much more
- challenge levels give you specific aims and reward you with medals

NOTE: If you get a blank white screen, disable "compatibility mode" in your phone settings.
