What is it about?

The Gem Miner Tycoon is a free idle game, which is similar to a mining game.

How does it work?

To begin with, you have to select the type of stone you want to mine, which can be gems, diamonds, rubies, etc.

Then, you need to find a location on the map where you can dig.

Once you're in the location, you have to start the digging process, which will take some time.

After finishing the digging process, you will be rewarded with a number of diamonds, rubies, and other gems.
