Coin Miner

Dig down through eight layers of rock, hire a crew and upgrade your pickaxe. An idle mining game that keeps working while you are away.

How to play

  1. Tap the pickaxe to dig. Every dig earns coins and takes you a little deeper.
  2. Spend coins on crew members who dig for you every second, and on better pickaxes that multiply what each dig earns.
  3. Deeper layers pay more per dig, from topsoil up to the molten core. Each crew member you buy costs 15% more than the last.
  4. Gold Rush triples your earnings for 20 seconds, then needs a minute to recharge. Close the page and your crew keeps digging at half speed for up to an hour.

Tips and strategy

  • Buy a pickaxe upgrade whenever you can afford one early on. It makes every dig and every crew dig worth more.
  • Fire off Gold Rush when you have a lot of crew working, since it multiplies all of it.
  • Check the cost of each crew type against how many digs it adds before you buy.
  • Dig by hand whenever you are here. Each tap pushes you toward the next, richer layer.
