Digging and blasting
You dig with bare hands. There is no shovel and no pickaxe: earth is dug away, rock and gold are blasted.

Digging
Section titled “Digging”- Start: press E. The digger digs diagonally downwards in the facing direction.
- Change direction: left and right turn the digging direction in 45° steps: diagonally down, horizontal, diagonally up, straight down. S stops.
- Automatic: if there is nothing to dig in the diagonal direction, he continues horizontally. If he hits something that cannot be dug, he stops.
- The tunnel is about 22 pixels high, smooth and round. Underground it leaves dark tunnel background, at the surface it becomes sky.

Blasting
Section titled “Blasting”
Buy flints at the base or make them in the chemical lab. Throw with Q, light with E E.
| Explosive | Value | Strength | Notes |
|---|---|---|---|
| Flint | 5 | 18 | explodes on impact |
| T-flint | 4 | 20 | timer, 60 ticks after lighting |
| Super flint | 10 | 30 | |
| Tera flint | 30 | 40 | from Ensign (Blaster) |
An explosion removes all blastable material in its radius. Gold, rock, ore and crystal turn into objects you can collect. Granite becomes rock.
Getting the gold up
Section titled “Getting the gold up”A digger carries a single nugget. The lorry does more: it holds 50 objects, is grabbed (S S) and pushed, and rides the elevator. At the home base gold sells automatically.
