World's Deepest Hole: digging and selling cargo
This is one of those skill games where you dig on Route 66 from a first person perspective. You fill the bucket, rise in the lift cage and sell each load to go deeper.
How to start digging and selling
First you go down to the nearest layer and fill a bucket with rock. Then you go upstairs and sell all the cargo to open the next passage. Each new layer becomes harder, so it is better not to linger at the bottom.
How many layers and chambers are there underground?
The game has 12 layers of rock and more than 20 underground chambers. Below are Crystal Caves, an Old Mine Tunnel, a Dungeon, a Diamond Vault, a Lava Cavity, an Underground Lake, a Mushroom Grotto, a Buried Diner, and a Lost Temple.
Tools, dynamite and museum
For money you buy new tools in the store, from a shovel to a laser. Hidden TNT is found in the rock, and dynamite and the Big Bomb help against hard layers. The museum hosts a 1957 Cadillac, a ringing pay phone, and dinosaur bones, and tourists pay to look at the exhibits, similar to Idle Supermarket Tycoon. Daily orders give you another goal for the day, and offline income doesn't stop when you leave.
