採礦大亨：掘金之旅 (Idle Miner Tycoon)

Gotta hit the goal in three days, so it's non-stop digging!

The hidden quests are all about watching ads.

It gets hard to dig once you reach the ice continent.

Fun, simple, and easy to pick up

Just playing a bit when I can, logging in occasionally to grab resources.

It's pretty good.

Simple mining, steady and stable upgrading.

Grinding and digging, digging and digging. Unlocking layer by layer. Upgrading, tapping, tapping, tapping

It's also an idle type with ads.

When hiring managers, try to keep the ones that minimize costs and upgrade them together when you upgrade.
